1/2/2020 2:00 PM | Many microbes wear beautifully patterned crystalline shells, which protect them from a harsh world and can even help them reel in food. Studies at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have revealed this food-reeling process and shown how shells assemble themselves from protein building blocks. | https://phys.org/news/2019-12-scientists-proteins-crystals-tile-microbe.html |
1/2/2020 4:00 PM | Particles can sometimes act like waves, and photons (particles of light) are no exception. Just as waves create an interference pattern, like ripples on a pond, so do photons. Physicists from the National Institute of Standards and Technology (NIST) and their colleagues have achieved a major new feat—creating a bizarre “quantum” interference between two photons of markedly different colors, originating from different buildings on the University of Maryland campus. | https://phys.org/news/2019-12-scientists-photon-pairs.html |

1/3/2020 6:00 PM | Phase transitions have long been of crucial importance to scientific research. The change from water to ice or steam is a simple example. A phase transition important to pioneering research today is that from metal to insulator in materials referred to as “correlated oxides.” Scientists have reaped many insights into phenomena like superconductivity and magnetism by studying what happens when a correlated oxide that conducts electricity with little or no resistance (metallike) changes to one that does not (insulator) as a result of changes in temperature, pressure, or other external fields. | https://phys.org/news/2019-12-materials-theory-relevant-ultrafast-electronics.html |

Our presence may even be ephemeral—a flash of luminescence in a great dark ocean. Or perhaps we are here to stay, somehow finding a way to transcend our worst instincts and ancient hatreds, and eventually become a galactic species. We could even find others out there, the inhabitants of distant, highly advanced civilizations—the Old Ones, as Sagan might put it. | https://www.smithsonianmag.com/science-nature/why-carl-sagan-truly-irreplaceable-180949818/ |
1/4/2020 2:00 PM | A team of mathematicians from the University of North Carolina at Chapel Hill and Brown University has discovered a new phenomenon that generates a fluidic force capable of moving and binding particles immersed in density-layered fluids.

1/9/2020 4:00 PM | The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate. However, scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current. Simulations by scientists from the University of Groningen and Utrecht University showed that it is unlikely that the current will come to a complete stop, due to small and rapid changes in precipitation over the North Atlantic. However, there is a 15 percent likelihood that there will be a temporary change in the current in the next 100 years. | https://phys.org/news/2019-12-north-atlantic-current-cease-temporarily.html |

The parents were raised well enough to survive and reproduce, and maternal grandmas are 25% related to the children which imparts a sense of biological closeness and responsibility. | https://carinbondar.com/2019/07/17/the-importance-of-animal-grandmas/ |
1/22/2020 10:00 AM | Hummingbirds are some of the most brightly-colored things in the entire world. Their feathers are iridescent— light bounces off them like a soap bubble, resulting in shimmering hues that shift as you look at them from different angles. While other birds like ducks can have bright feathers, nothing seems to come close to hummingbirds, and scientists weren’t sure why. But a new study shows that while hummingbird feathers have the same basic makeup as other birds’, the special shape of their pigment-containing structures enables them to reflect a rainbow of light. | https://phys.org/news/2020-01-hummingbirds-rainbow-pancake-shaped-feathers.html |
1/22/2020 12:00 PM | Researchers at University of California San Diego School of Medicine have discovered how a new immune system works to protect bacteria from bacteriophages (phages), viruses that specifically infect bacteria.

1/27/2020 2:00 PM | 15,000 years ago, some water froze atop the Tibetan Plateau and became part of a glacier. While humans were busy domesticating dogs, the ice entrapped millions of microscopic organisms per square inch. Many of the tiny life forms died, and their genomes—the only proof that they had been there in the first place—slowly degraded. Then, in 2015, scientists from the U.S. and China drilled down 50 meters into the glacier to see what they could find. | https://www.vice.com/en_us/article/pkebx9/scientists-found-ancient-never-before-seen-viruses-in-a-glacier |

2/11/2020 8:00 AM | In 1966, two Caltech scientists were ruminating on the implications of the thin carbon dioxide (CO2) Martian atmosphere first revealed by Mariner IV, a NASA fly-by spacecraft built and flown by JPL. They theorized that Mars, with such an atmosphere, could have a long-term stable polar deposit of CO2 ice that, in turn, would control global atmospheric pressure. A new study from Caltech suggests that the theory, developed by physicist Robert B. Leighton (BS ’41, MS ’44, Ph.D. ’47) and planetary scientist Bruce C. Murray, may indeed be correct. | https://phys.org/news/2020-01-mystery-mars-pole.html |

2/11/2020 6:00 PM | One of the cornerstones of quantum theory is a fundamental limit to the precision with which we can know certain pairs of physical quantities, such as position and momentum. For quantum theoretical treatments, this uncertainty principle is couched in terms of the Heisenberg limit, which allows for physical quantities that do not have a corresponding observable in the formulation of quantum mechanics, such as time and energy, or the phase observed in interferometric measurements. It sets a fundamental limit on measurement accuracy in terms of the resources used. Now, a collaboration of researchers in Poland and Australia have proven that the Heisenberg limit as it is commonly stated is not operationally meaningful, and differs from the correct limit by a factor of π. | https://phys.org/news/2020-02-heisenberg-limit-meaningful.html |

2/29/2020 12:00 PM | NASA’s Juno mission has provided its first science results on the amount of water in Jupiter’s atmosphere. Published recently in the journal Nature Astronomy, the Juno results estimate that at the equator, water makes up about 0.25% of the molecules in Jupiter’s atmosphere—almost three times that of the Sun. These are also the first findings on the gas giant’s abundance of water since the agency’s 1995 Galileo mission suggested Jupiter might be extremely dry compared to the Sun (the comparison is based not on liquid water but on the presence of its components, oxygen and hydrogen, present in the Sun). | https://phys.org/news/2020-02-nasa-juno-jupiter-mystery.html |

3/2/2020 12:00 PM | Surprising new data from NASA’s Hubble Space Telescope suggests the smooth, settled “brim” of the Sombrero galaxy’s disk may be concealing a turbulent past. Hubble’s sharpness and sensitivity resolves tens of thousands of individual stars in the Sombrero’s vast, extended halo, the region beyond a galaxy’s central portion, typically made of older stars. These latest observations of the Sombrero are turning conventional theory on its head, showing only a tiny fraction of older, metal-poor stars in the halo, plus an unexpected abundance of metal-rich stars typically found only in a galaxy’s disk, and the central bulge. Past major galaxy mergers are a possible explanation, though the stately Sombrero shows none of the messy evidence of a recent merger of massive galaxies. | https://phys.org/news/2020-02-brim-sombrero-galaxy-halo-turbulent.html |
3/2/2020 2:00 PM | In a new paper, climate scientists at the University of Massachusetts Amherst and Woods Hole Oceanographic Institution propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age, from about 8,000 to 13,000 years ago. | https://phys.org/news/2020-02-huge-arctic-sea-ice-contributed.html |

3/9/2020 4:00 PM | A group of scientists from the RIKEN Center for Emergent Matter Science in Japan has succeeded in taking repeated measurements of the spin of an electron in a silicon quantum dot (QD) without changing its spin in the process. This type of “non-demolition” measurement is important for creating quantum computers that are fault-tolerant. Quantum computers would make it easier to perform certain classes of calculations such as many-body problems, which are extremely difficult and time-consuming for conventional computers. Essentially, the involve measuring a quantum value that is never in a single state like a conventional transistor, but instead exists as a “superimposed state”—in the same way that Schrodinger’s famous cat cannot be said to be alive or dead until it is observed. Using such systems, it is possible to conduct calculations with a qubit that is a superimposition of two values, and then determine statistically what the correct result is. Quantum computers that use single electron spins in silicon QDs are seen as attractive due to their potential scalability and because silicon is already widely used in electronics technology. | https://phys.org/news/2020-03-scientists-electron-qubit-demolishing.html |

3/13/2020 12:00 PM | The size of a star is a natural consequence of the balance between the inward pull of gravity and the outward pressure of radiation produced inside the star. When these two forces are balanced, the outer layers of the star are stable and said to be in hydrostatic equilibrium. In general, both the gravitational force and the energy generation rate are determined by the mass of a star. During most of their lives, stars burn hydrogen in their cores, and their structures are almost completely determined by their masses. Later in their lifetimes, energy is generated in a shell surrounding their cores, and the outer layers expand, such as in the red supergiant (for higher-mass stars) and red giant (for lower-mass stars) phases. | https://astronomy.com/magazine/ask-astro/2018/06/big-stars |

4/4/2020 8:00 AM | Chiral superconductors are unconventional superconducting materials with distinctive topological properties, in which time-reversal symmetry is broken. Two of the first materials to be identified as chiral superconductors are UPt3 and Sr2RuO4. So far, experimental evidence for broken time-reversal symmetry in both these materials was based primarily on surface measurements collected at a magnetic field equal to zero. | https://phys.org/news/2020-03-evidence-broken-time-reversal-symmetry-topological.html |

4/5/2020 8:00 AM | When cocaine kingpin Pablo Escobar was shot dead in 1993, the four hippos he brought to his private zoo in Colombia were left behind in a pond on his ranch. Since then, their numbers have grown to an estimated 80-100, and the giant herbivores have made their way into the country’s rivers. Scientists and the public alike have viewed Escobar’s hippos as invasive pests that by no rights should run wild on the South American continent. | https://phys.org/news/2020-03-species.html |

4/5/2020 4:00 PM | Almost 35 years ago, scientists made the then-radical proposal that colossal hydrogen bombs called novae go through a very long-term life cycle after erupting, fading to obscurity for hundreds of thousands of years and then building back up to become full-fledged novae once more. A new study is the first to fully model the work and incorporate all of the feedback factors now known to control these systems, backing up the original prediction while bringing new details to light. | https://phys.org/news/2020-03-contested-year-old-novae-iceberg.html |

4/9/2020 6:00 PM | When descendants of ancient fish first hauled themselves onto dry land, they didn’t do so with lungs evolved specifically for that reason. The need to breathe air ultimately led to a change in the function of an organ the fish already had. Likewise, when birds took to the air millions of years later, they did so using feathers that may have originally evolved as insulation or as a way to attract mates. | https://www.sciencenews.org/article/new-book-captures-how-genetics-fills-story-life-evolution |

4/19/2020 2:00 PM | Photosynthesis on Earth is regulated by plant phenology—how plant life cycles interact with the climate—and environmental conditions, both of which changed substantially in recent decades. Unlike early-season photosynthesis which is mostly driven by warming temperatures or the onset of the wet season, late-season photosynthesis can be limited by several factors, such as plant life cycle and radiation, and its underlying mechanisms are less understood. Late-season photosynthesis on land contributes greatly to annual total carbon fixation and is sensitive to climate. Scientists generally agree that temperature limitation on late-season photosynthesis will alleviate with warming but the effects of water availability are highly uncertain. | https://phys.org/news/2020-04-precipitation-essential-counteract-global.html |
4/19/2020 4:00 PM | High vibrational states of the Magnesium dimer (Mg2) are an important system in studies of fundamental physics, although they have eluded experimental characterization for half a century. Experimental physicists have so far resolved the first 14 vibrational states of Mg2, despite reports that the ground-state may support five additional levels. In a new report, Stephen H. Yuwono and a research team in the departments of physics and chemistry at the Michigan State University, U.S., presented highly accurate initial potential energy curves for the ground and excited electron states of Mg2. They centered the experimental investigations on calculations of state-of-the-art coupled-cluster (CC) and full configuration interaction computations of the Mg2 dimer. The ground-state potential confirmed the existence of 19 vibrational states with minimal deviation between previously calculated rovibrational values and experimentally derived data. | https://phys.org/news/2020-04-quantum-enigma-vibrational-states-magnesium.html |

5/12/2020 12:00 PM | Blood flow in the human body is generally assumed to be smooth due to its low speed and high viscosity. Unsteadiness in blood flow is linked to various cardiovascular diseases and has been shown to promote dysfunction and inflammation in the inner layer of blood vessels, the endothelium. In turn, this can lead to the development of arteriosclerosis—a leading cause of death worldwide—where arterial pathways in the body narrow due to plaque buildup. However, the source of this unsteadiness is not well understood. Now, IST Austria professor Björn Hof, together with an international team of researchers, has shown that pulsating blood flows, such as those from our heart, react strongly to geometric irregularities in vessels (such as plaque buildup) and cause much higher levels of velocity fluctuations than previously expected. The research could have implications on how we study blood flow related diseases in the future. | https://phys.org/news/2020-05-blood-turbulent-previously.html |

5/13/2020 6:00 PM | Snakes should be good at social distancing, at least according to what we know about reptiles: Most are solitary creatures that come together to mate and hibernate, but not much else. Not so garter snakes, the harmless serpents that live throughout North America and part of Central America. Researchers have discovered that garter snakes not only prefer to hang out together, but also seem to have “friends” with whom they spend much of their time. | https://www.sciencemag.org/news/2020/05/garter-snakes-are-surprisingly-social-forming-friendships-fellow-serpents |
5/14/2020 8:00 AM | We can now add atmospheric craziness to WASP-79b’s already substantial exotic appeal. The gas-giant exoplanet, which lies about 780 light-years from Earth, circles extremely close to its bright host star, completing one orbit every 3.7 Earth days. That proximity makes WASP-79b scorching hot, with an average temperature around 3,000 degrees Fahrenheit (1,650 degrees Celsius), NASA officials said. | https://www.space.com/giant-hot-alien-planet-wasp-79b-has-yellow-skies.html |

5/14/2020 2:00 PM | A spacecraft that died in 2017 is still providing insights about Saturn, the planet it studied up close for 13 years. NASA’s Cassini spacecraft helped scientists to discover why Saturn’s upper atmosphere is so hot, which puzzled planetary scientists for decades since the planet is too far from the sun to receive our star’s heat. But, using old data from Cassini, scientists are closer to solving this mystery. | https://www.space.com/saturn-hot-atmosphere-mystery-cassini-spacecraft-discovery.html |
5/14/2020 4:00 PM | Researchers using a technique known as “lucky imaging” with the Gemini North telescope on Hawaii’s Maunakea have collected some of the highest resolution images of Jupiter ever obtained from the ground. These images are part of a multi-year joint observing program with the Hubble Space Telescope in support of NASA’s Juno mission. The Gemini images, when combined with the Hubble and Juno observations, reveal that lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid. The new observations also confirm that dark spots in the famous Great Red Spot are actually gaps in the cloud cover and not due to cloud color variations. | https://phys.org/news/2020-05-gemini-lucky-deep-jupiter-clouds.html |
5/14/2020 6:00 PM | Many galaxies far more active than the Milky Way have enormous twin jets of radio waves extending far into intergalactic space. Normally these go in opposite directions, coming from a massive black hole at the centre of the galaxy. However, a few are more complicated and appear to have four jets forming an ‘X’ on the sky. | https://phys.org/news/2020-05-south-africa-meerkat-mystery-x-galaxies.html |
5/15/2020 8:00 AM | Exotic atoms in which electrons are replaced by other subatomic particles of the same charge allow deep insights into the quantum world. After eight years of ongoing research, a group led by Masaki Hori, senior physicist at the Max Planck Institute of Quantum Optics in Garching, Germany, has now succeeded in a challenging experiment: In a helium atom, they replaced an electron with a pion in a specific quantum state and verified the existence of this long-lived “pionic helium” for the very first time. The usually short-lived pion could thereby exist 1000 times longer than it normally would in other varieties of matter. Pions belong to an important family of particles that determine the stability and decay of atomic nuclei. The pionic helium atom enables scientists to study pions in an extremely precise manner using laser spectroscopy. | https://phys.org/news/2020-05-long-lived-pionic-helium-exotic-experimentally.html |
5/15/2020 10:00 AM | Most everyone knows that humid heat is harder to handle than the “dry” kind. And recently, some scientists have projected that later in the century, in parts of the tropics and subtropics, warming climate could cause combined heat and humidity to reach levels rarely if ever experienced before by humans. Such conditions would ravage economies, and possibly even surpass the physiological limits of human survival. | https://phys.org/news/2020-05-potentially-fatal-combinations-humidity-emerging.html |

If we could replace even a part of that with algal biohydrogen that is made via light and water, it would have a substantial impact. | https://techxplore.com/news/2020-05-scientists-rewire-photosynthesis-fuel-future.html |
5/16/2020 12:00 PM | If lightning exists on Mars, it may be less energetic and frequent than lightning on Earth, all because of the Red Planet’s thin air, a new study finds. Scientists announced the first evidence of lightning on Mars in 2009, after they detected microwave emissions from a 2006 dust storm on the Red Planet that the researchers suggested came from sudden, huge electrical discharges. | https://www.space.com/mars-lightning-weak-thin-atmosphere.html |
5/16/2020 2:00 PM | A new method for reliably identifying the presence of beer or other malted foodstuffs in archaeological finds is described in a study published May 6, 2020 in the open-access journal PLOS ONE by Andreas G. Heiss from the Austrian Academy of Sciences (OeAW), Austria and colleagues. A beverage with prehistoric roots, beer played ritual, social, and dietary roles across ancient societies. However, it’s not easy to positively identify archaeological evidence of cereal-based alcoholic beverages like beer, since most clear markers for beer’s presence lack durability or reliability. | https://www.eurekalert.org/pub_releases/2020-05/p-bwh042920.php |

5/17/2020 10:00 AM | Public health advice for avoiding respiratory illness is largely unchanged since the Spanish flu of 1918, one of history’s deadliest pandemics. Keep a safe distance from other people. Wash your hands frequently with soap and water to kill any germs you may have picked up. Cover your nose and mouth with a face mask—even one fashioned from a bandana will do. Such guidance is based on the understanding that respiratory infections spread through virus-carrying droplets that are expelled when infected people cough, sneeze, or breathe. | https://phys.org/news/2020-05-fluid-dynamics-covid-spreadand.html |
5/17/2020 12:00 PM | Scientists around the world are intensively working on memristive devices that draw extremely low power and behave similarly to neurons in the brain. Researchers from the Jülich Aachen Research Alliance (JARA) and the German technology group Heraeus now report the systematic control of the functional behavior of these elements. The smallest differences in material composition turned out to be crucial, so small that until now, experts had failed to notice them. The researchers’ design directions could help to increase variety, efficiency, selectivity and reliability for memristive technology-based applications, for example, energy-efficient, non-volatile storage devices or neuro-inspired computers. | https://phys.org/news/2020-05-memresistor-material-composition-breakthrough.html |
5/17/2020 2:00 PM | There is ongoing debate among policymakers and the general public about where SARS-CoV-2, the virus that causes COVID-19, came from. While researchers consider bats the most likely natural hosts for SARS-CoV-2, the origins of the virus are still unclear. On May 10 in the journal Current Biology, researchers describe a recently identified bat coronavirus that is SARS-CoV-2’s closest relative in some regions of the genome and which contains insertions of amino acids at the junction of the S1 and S2 subunits of the virus’s spike protein in a manner similar to SAR-CoV-2. While it’s not a direct evolutionary precursor of SARS-CoV-2, this new virus, RmYN02, suggests that these types of seemingly unusual insertion events can occur naturally in coronavirus evolution, the researchers say. | https://phys.org/news/2020-05-relative-sars-cov-evidence-evolved-naturally.html |

5/18/2020 4:00 PM | There are places on Earth that are a little creepy, places that feel a little haunted and places that are downright hellish. The Darvaza gas crater, nicknamed by locals “The Door to Hell,” or “The Gates of Hell,” definitely falls into the latter category—and its sinister burning flames are just the half of it. Located in the Karakum Desert of central Turkmenistan (a little over 150 miles from the country’s capital) the pit attracts hundreds of tourists each year. It also attracts nearby desert wildlife—reportedly, from time to time local spiders are seen plunging into the pit by the thousands, lured to their deaths by the glowing flames. | https://www.smithsonianmag.com/travel/giant-hole-ground-has-been-fire-more-40-years-180951247/ |

5/25/2020 2:00 PM | When early tetrapods transitioned from water to land the way they breathed air underwent an evolutionary revolution. Fish use muscles in their head to pump water over their gills. The first land animals utilized a similar technique—modern frogs still use their head and throat to force air into their lungs. Then another major transformation in vertebrate evolution took place that shifted breathing from the head to the torso. In reptiles and mammals, the ribs expand to create a space in the chest that draws in breath. But what caused the shift? | https://phys.org/news/2020-05-ribs-evolved-movement-co-opted.html |

5/27/2020 2:00 PM | If you ask astronomers how many planets in the universe harbor life, they will likely say there are only two possible answers: one or infinity. We can rule out zero, thanks to the decidedly alive Earth, which means that so far one is the answer. But if we discover another, the answer jumps straight past two to infinity. The reason: You can posit a universe in which the confluence of factors that made life possible here are so complex that the right roll of the dice could statistically happen only once. But if it can happen more than once, why should there be any limit? (Actually, something could be so rare in nature that it happens only two or three times, but the overall zero-one-infinity idea originated with theologians debating atheism, monotheism and infinite polytheism, and planetary scientists just kind of liked it and claimed it as their own.) | https://time.com/5763768/toi-700-d-goldilocks-planet/ |

5/31/2020 8:00 AM | Since the outbreak of COVID-19, there’s been a worldwide shortage of face masks—particularly, the N95 ones worn by health care workers. Although these coverings provide the highest level of protection currently available, they have limitations. Now, researchers reporting in ACS Nano have developed a membrane that can be attached to a regular N95 mask and replaced when needed. The filter has a smaller pore size than normal N95 masks, potentially blocking more virus particles. | https://phys.org/news/2020-05-efficient-filter-n95-masks.html |
5/31/2020 10:00 AM | Catmint, also known as catnip, is well-known for its intoxicating effect on cats. The chemical responsible for the cats’ strange behavior is nepetalactone, a volatile iridoid produced by catmint. An international team of researchers has now found through genome analysis that the ability to produce iridoids had already been lost in ancestors of catmint in the course of evolution. Hence, nepetalactone biosynthesis is the result of repeated evolution. Nevertheless, this particular iridoid differs considerably from other compounds in this group of natural products with regards to its chemical structure and properties, and most likely its ecological functions. | https://phys.org/news/2020-05-mint-catmint.html |

6/4/2020 2:00 PM | As embryos develop, tissues flow and reorganize dramatically on timescales as brief as minutes. This reorganization includes epithelial tissues that cover outer surfaces and inner linings of organs and blood vessels. As the embryo develops, these tissues often narrow along one axis and extend along a perpendicular axis through cellular movement caused by external or internal forces acting differently along various directions in the tissue (anisotropies). Researchers have long wondered how simple clusters of cells inside developing embryos transform into tissues and organs—how do tissues physically change shape in the embryo? Might they turn from “solids” into “fluids” at specific times in development to make it easier to rapidly sculpt functional tissues and organs? | https://phys.org/news/2020-05-view-tissues-embryo.html |

6/15/2020 8:00 AM | According to new research by SISSA, ICTP and INFN, black holes could be like holograms, in which all the information to produce a three-dimensional image is encoded in a two-dimensional surface. As affirmed by quantum theories, black holes could be incredibly complex, and concentrate an enormous amount of information in two dimensions, like the largest hard disks that exist in nature. This idea aligns with Einstein’s theory of relativity, which describes black holes as three dimensional, simple, spherical and smooth, as depicted in the first-ever image of a black hole that circulated in 2019. In short, black holes appear to be three dimensional, just like holograms | https://phys.org/news/2020-06-black-holes-hologram.html |

6/15/2020 6:00 PM | Of the advanced propulsion concepts that could theoretically make interstellar space travel possible, few have generated as much excitement—and controversy—as the EmDrive. First described nearly two decades ago, the EmDrive works by converting electricity into microwaves and channeling this electromagnetic radiation through a conical chamber. In theory, the microwaves can exert force against the walls of the chamber to produce enough thrust to propel a spacecraft once it’s in space. At this point, however, the EmDrive exists only as a laboratory prototype, and it’s still unclear whether it’s able to produce thrust at all. If it does, the forces it generates aren’t strong enough to be registered by the naked eye, much less propel a spacecraft. | https://www.wired.com/story/a-mythical-form-of-space-propulsion-finally-gets-a-real-test/ |

The freezing temperatures in parts of Russia, particularly Siberia, may be tough for most folks to cope with, especially during the long winter months. But for scientists, the region can provide tremendous learning opportunities, because the permafrost often captures, and preserves, animal and bird specimens that the cold keeps largely unchanged from their original forms for.

6/17/2020 2:00 PM | The end of the Devonian period, 359 million years ago, was an eventful time: Fish were inching out of the ocean, and fernlike forests were advancing on land. The world was recovering from a mass extinction 12 million years earlier, but the climate was still chaotic, swinging between hothouse conditions and freezes so deep that glaciers formed in the tropics. And then, just as the planet was warming from one of these ice ages, another extinction struck, seemingly without reason. Now, spores from fernlike plants, preserved in ancient lake sediments from eastern Greenland, suggest a culprit: The planet’s protective ozone layer was suddenly stripped away, exposing surface life to a blast of mutation-causing ultraviolet (UV) radiation. | https://www.sciencemag.org/news/2020/05/no-asteroids-or-volcanoes-needed-ancient-mass-extinction-tied-ozone-loss-warming |

With an incidence angle of 26.5° and a shadow of 55 meters, scientists can estimate the depth to be a bit over 100 meters. That estimate is from the edge of the shadow, which begins a slightly downslope from the gradual margin of the pits. When measured from the level of the surrounding mare plain, the depth of the pit is even greater.

Dubbed KOI-456.04, the planet is located just over 3,000 light-years away from the solar system orbiting its parent star, named Kepler-160, close enough there could even be liquid water on the planet’s surface. | https://www.cosmosup.com/astronomers-find-the-most-earth-like-planet-orbiting-a-sun-like-star/ |
6/20/2020 8:00 AM | On October 11, 1984, geologist Kathryn D. Sullivan became the first U.S. woman to take a walk in space, spending more than three hours outside the Challenger shuttle in Earth’s orbit. On June 8, 2020, the now 68-year-old former NASA astronaut and three-time veteran of flights on the Space Shuttle set another record. Together with retired naval officer, successful investor, and undersea explorer Victor Lance Vescovo (born 1966), she became the first woman (and 8th person in history) to reach the deepest point on Earth’s surface, the 10,984 meters deep Mariana Trench in the western Pacific Ocean. | https://www.forbes.com/sites/davidbressan/2020/06/09/geologist-and-former-nasa-astronaut-becomes-first-woman-to-reach-earths-deepest-point/ |

6/27/2020 10:00 AM | Egyptian Blue, also known as calcium copper silicate, is one of the first artificial pigments known to have been used by man. The oldest known example of the exquisite pigment is said to be about 5000 years old, found in a tomb painting dated to the reign of Ka-Sen, the last pharaoh of the First Dynasty. Others, however, state that the earliest evidence of the use of Egyptian blue is from the Fourth Dynasty and the Middle Kingdom, around 4,500 years ago. Nevertheless, by the New Kingdom, Egyptian Blue was used plentifully as a pigment in painting and can be found on statues, tomb paintings and sarcophagi. In addition, Egyptian blue was used to produce a ceramic glaze known as Egyptian faience. | https://www.ancient-origins.net/ancient-technology/egyptian-blue-oldest-artificial-pigment-ever-produced-001745? |

7/1/2020 4:00 PM | Meganeura is a genus of extinct insects from the Carboniferous period (approximately 300 million years ago), which resembled and are related to the present-day dragonflies. Its wingspans from 65 cm (25.6 in) to more than 70 cm (28 in), M.Monyi is one of the largest known species of flying insects. Meganeura was predatory and their diet consisted mainly of other insects. | http://www.geologypage.com/2020/03/meganeura-the-largest-insect-ever-existed-was-a-giant-dragonfly.html |
7/1/2020 6:00 PM | 90,000 years ago, a young girl lived in a cave in the Altai mountains in southern Siberia. Her life was short; she died in her early teens, but she stands at a unique point in human evolution. She is the first known hybrid of two different kinds of ancient humans: the Neanderthals and the Denisovans. | https://bigthink.com/scotty-hendricks/90000-year-old-neanderthal-denisovan-human-hybrid-found-in-ancient-cave |
7/2/2020 8:00 AM | Scientists from the international XENON collaboration, an international experimental group including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), University of Tokyo; the Institute for Cosmic Ray Research (ICRR), University of Tokyo; the Institute for Space-Earth Environmental Research (ISEE), Nagoya University; the Kobayashi-Maskawa Institute for the Origin of Particles and the Universe (KMI), Nagoya University; and the Graduate School of Science, Kobe University, announced today that data from their XENON1T, the world’s most sensitive dark matter experiment, show a surprising excess of events. The scientists do not claim to have found dark matter. Instead, they have observed an unexpected rate of events, the source of which is not yet fully understood. The signature of the excess is similar to what might result from a tiny residual amount of tritium (a hydrogen atom with one proton and two neutrons), but could also be a sign of something more exciting—such as the existence of a new particle known as the solar axion or the indication of previously unknown properties of neutrinos. | https://phys.org/news/2020-06-excess-events-xenon1t-dark.html |

7/14/2020 2:00 PM | Astronomers have spotted the exposed core of a massive alien world, an unprecedented find that could shed considerable light on planet formation, evolution and diversity. The planetary core, called TOI-849b, is unlike anything scientists have seen before, and it could hide a wealth of exciting information in its bizarre depths. | https://www.space.com/exposed-planetary-core-discovery-nasa-tess.html |
7/14/2020 4:00 PM | The universe, as seen through the lens of quantum mechanics, is a noisy, crackling space where particles blink constantly in and out of existence, creating a background of quantum noise whose effects are normally far too subtle to detect in everyday objects. | https://phys.org/news/2020-07-quantum-fluctuations-jiggle-human-scale.html |
7/14/2020 6:00 PM | If the world is to maintain a sustainable economy and fend off the worst effects of climate change, at least one industry will soon have to ramp up dramatically: the mining of metals needed to create a vast infrastructure for renewable power generation, storage, transmission and usage. The problem is, demand for such metals is likely to far outstrip currently both known deposits and the existing technology used to find more ore bodies. | https://phys.org/news/2020-06-geologists-deep-earth-hidden-metal-lodes.html |
7/15/2020 8:00 AM | In 1981, many of the world’s leading cosmologists gathered at the Pontifical Academy of Sciences, a vestige of the coupled lineages of science and theology located in an elegant villa in the gardens of the Vatican. Stephen Hawking chose the August setting to present what he would later regard as his most important idea: a proposal about how the universe could have arisen from nothing. | https://www.quantamagazine.org/physicists-debate-hawkings-idea-that-the-universe-had-no-beginning-20190606/ |

7/15/2020 2:00 PM | This past autumn, a professor at Wuhan University named Jau Tang was hard at work piecing together a thruster prototype that, at first, sounds too good to be true. The basic idea, he said in an interview, is that his device turns electricity directly into thrust — no fossil fuels required — by using microwaves to energize compressed air into a plasma state and shooting it out like a jet. | https://futurism.com/scientist-jet-engine-electricity-thrust |
7/15/2020 4:00 PM | Physicists have reported what could be the first incontrovertible evidence for the existence of unusual particle-like objects called anyons, which were first proposed more than 40 years ago. Anyons are the latest addition to a growing family of phenomena called quasiparticles, which are not elementary particles, but are instead collective excitations of many electrons in solid devices. Their discovery — made using a 2D electronic device — could represent the first steps towards making anyons the basis of future quantum computers. | https://www.nature.com/articles/d41586-020-01988-0 |
7/15/2020 6:00 PM | Solar energy researchers at Oregon State University are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago. Not all materials with the structure, known as perovskites, are semiconductors. But perovskites based on a metal and a halogen are, and they hold tremendous potential as photovoltaic cells that could be much less expensive to make than the silicon-based cells that have owned the market since its inception in the 1950s. | https://phys.org/news/2020-07-crystal-years-key-solar-cell.html |
7/16/2020 8:00 AM | SRON-astronomers have found the signature for aluminum oxide (AlO) in the spectrum of exoplanet WASP-43b. This came as a surprise because AlO is expected to stay hidden in the lower atmospheric layers. It is only the second time that astronomers have observed the molecule in an exoplanet’s atmosphere. | https://phys.org/news/2020-06-astronomers-unexpected-molecule-exoplanet-atmosphere.html |

7/16/2020 2:00 PM | Let’s turn back the hands of time. Before extinction knocked dinosaurs off their pillar, before the “Great Dying” extinction wiped out 95% of all organisms – we had the Paleozoic Era. During this age in Earth’s history, between 541 million and 252 million years ago, arthropods (animals with exoskeletons such as insects, crustaceans, scorpions, and horseshoe crabs) were exploring the extremes of size, from tiny to huge. | https://theconversation.com/giant-sea-scorpions-were-the-underwater-titans-of-prehistoric-australia-141290 |

7/17/2020 8:00 AM | Textbooks had to be rewritten. Members of the public were outraged. Our understanding of the solar system itself was forever changed on Aug. 24, 2006, when researchers at the International Astronomical Union (IAU) voted to reclassify Pluto, changing its status from a planet to a dwarf planet — a relegation that was largely seen as a demotion and which continues to have reverberations to this day. | https://www.space.com/why-pluto-is-not-a-planet.html |
7/17/2020 10:00 AM | Astronauts caught a stunning natural light show this weekend from a comet that has been dazzling skywatchers on Earth as well. That streaker, called Comet NEOWISE or C/2020 F3, first came on the scene at the end of March. At that point, the icy lump was quite faint in our skies, and astronomers weren’t sure that would change. But as time has passed, the comet has brightened immensely, tantalizing skywatchers even after they were disappointed by two other recent comets that faded away. | https://www.space.com/comet-neowise-space-station-astronaut-photos.html |

7/18/2020 8:00 AM | How did the chemical makeup of our planet’s core shape its geologic history and habitability? Life as we know it could not exist without Earth’s magnetic field and its ability to deflect dangerous ionizing particles from the solar wind and more far-flung cosmic rays. It is continuously generated by the motion of liquid iron in Earth’s outer core, a phenomenon called the geodynamo. | https://phys.org/news/2020-07-earth-sustain-magnetic-field.html |
7/18/2020 10:00 AM | Fossils can tell scientists a lot about prehistoric life, but they can’t say everything. When it comes to understanding our animal and plant forebears, there’s a lot we’ll probably never learn from fossils, like what colors ancient animals were. However, in rare cases, researchers get lucky. In a new paper published in the journal, Proceedings of the Royal Society B, by a team of researchers at the Nanjing Institute of Geology and Paleontology, the group identified the true colors of three ancient insects that were preserved in amber—an incredibly rare find for paleontologists. | https://www.popsci.com/story/animals/ancient-insects-amber-colors/ |
7/18/2020 12:00 PM | New research provides the first direct evidence for the Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for weather, climate and fisheries because ocean mixing plays a critical role in these processes. The Gulf Stream is one of the largest drivers of climate and biological productivity from Florida to Newfoundland and along the western coast of Europe. | https://phys.org/news/2020-07-evidence-ocean-gulf-stream.html |
7/18/2020 2:00 PM | Dinosaurs and flying pterosaurs may be known for their remarkable size, but a newly described species from Madagascar that lived around 237 million years ago suggests that they originated from extremely small ancestors. The fossil reptile, named Kongonaphon kely, or “tiny bug slayer,” would have stood just 10 centimeters (or about 4 inches) tall. The description and analysis of this fossil and its relatives may help explain the origins of flight in pterosaurs, the presence of “fuzz” on the skin of both pterosaurs and dinosaurs, and other questions about these charismatic animals. | https://phys.org/news/2020-07-tiny-ancient-relative-dinosaurs-pterosaurs.html |

7/19/2020 4:00 PM | Imagine being able to disappear from one place and then reappear in the exact same condition at another location. You could visit your favorite bakery in Paris for breakfast, spend the afternoon on a beach in Thailand, and — why relegate yourself to Earth? — beam yourself up to the moon before going home to your dinner. The idea of teleportation is fascinating and prevalent in science fiction – and while seemingly unattainable, it is not actually impossible according to the laws of physics … it just depends on scale. | https://www.advancedsciencenews.com/teleportation-is-possible-it-just-depends-on-scale/ |
7/19/2020 6:00 PM | Wormholes make the best shortcuts in the universe. That’s true in a literal sense, since the theoretical things can connect distant corners of the cosmos (or even different universes), allowing a traveler to go someplace without having to visit everywhere in between. Too bad, then, that as far as we know, the things don’t exist.

7/26/2020 12:00 PM | Hypernovas are the most powerful supernova explosions in the universe, 10 to even up to 100 times brighter than a typical supernova. That’s enough energy to completely obliterate our sun 100,000 times over, or enough energy to supply our world’s current total power consumption for the next billion, billion, billion years. | https://www.space.com/how-to-make-a-hypernova-explosion.html |
7/26/2020 2:00 PM | All chimpanzees eat animals at least sometimes, including anything from ants and termites to bushpigs and even baboons. Monkeys, in fact, are typically the most frequent item on the menu, and in some cases chimpanzees can eat so many monkeys they threaten to wipe out entire populations. One group in Senegal even hunts tiny, mouse-like primates known as bushbabies by using spear-like tools to first probe the holes the bushbabies hide in during the day, before reaching in to grab their prey. But until now scientists had never observed them eating reptiles. | https://www.popsci.com/chimpanzees-smashing-eating-tortoises-cognition-tools/ |
7/26/2020 4:00 PM | The Hyksos, who ruled during the 15th Dynasty of ancient Egypt, were not foreign invaders, but a group who rose to power from within, according to a study published July 8, 2020. The Hyksos were a foreign dynasty that ruled parts of Egypt between approximately 1638-1530 BCE, the first instance of Egypt being ruled by individuals of a foreign origin. The common story is that the Hyksos were invaders from a far-off land, but this idea has been drawn into question. Archaeological evidence does link Hyksos culture with an origin in the Near East, but exactly how they rose to power is unclear. | https://phys.org/news/2020-07-hyksos-15th-dynasty-rulers-ancient.html |

7/29/2020 4:00 PM | After expanding their search, a team of researchers found that the Red Planet’s ancient subsurface could have housed microbial life for hundreds of millions of years. By borrowing hydrogen electrons from water, microbes could’ve had enough energy to not only survive underground, but to thrive for miles below the surface. If true, future missions could search areas where the subsurface is now exposed and potentially prove the existence of Martian life once and for all. | https://astronomy.com/news/2018/09/mars-underground-habitable-zone-could-have-hosted-life-for-millions-of-years |
7/29/2020 6:00 PM | Sunspots and their behavior are direct manifestations of the Sun’s magnetic field, which we still don’t fully understand. Here’s what we do know: Ex-tremely hot gas, called plasma, in the Sun’s outer atmosphere rotates differentially — faster at the middle than at the poles — while plasma in the interior rotates as a solid body. The rotation of the charged solar plasma produces a current. This current creates a magnetic field like that of a bar magnet with a north pole and a south pole aligned with the axis of rotation, but the differences of rotation speed mean the magnetic field becomes wound up and tangled. | https://astronomy.com/magazine/ask-astro/2013/08/solar-blemishes |

8/1/2020 8:00 AM | You’ve probably noticed that our appetite for storing data is ravenous. Just three or four years ago, we thought a terabyte of storage space was ridiculously capacious. Now, multi-terabyte storage is an everyday thing. And it’s not just the data we want to stash away that we’re having trouble handling. It’s also the bits coursing through our processors and the power those straining processors require. We’re reaching the limits of our hardware, so only a breakthrough in efficiency that packs data into a much tinier form than it currently inhabits could break through the wall we’ve been rapidly approaching. | https://bigthink.com/technology-innovation/data-on-single-atoms |

Lewis ran tests until around 3:00 in the morning, then ended up sleeping in the next day. It was like she had jet lag, she says, without changing time zones. It’s not that Lewis doesn’t appreciate the merits of a good night’s sleep. She does. But when you’re trying to map what’s happening in a slumbering human’s brain, you end up making some sacrifices. “It’s this great irony of sleep research,” she says. “You’re constrained by when people sleep.” | https://www.wired.com/story/scientists-now-know-how-sleep-cleans-toxins-from-the-brain/ |

8/4/2020 4:00 PM | The size of a star is a natural consequence of the balance between the inward pull of gravity and the outward pressure of radiation produced inside the star. When these two forces are balanced, the outer layers of the star are stable and said to be in hydrostatic equilibrium. In general, both the gravitational force and the energy generation rate are determined by the mass of a star. During most of their lives, stars burn hydrogen in their cores, and their structures are almost completely determined by their masses. Later in their lifetimes, energy is generated in a shell surrounding their cores, and the outer layers expand, such as in the red supergiant (for higher-mass stars) and red giant (for lower-mass stars) phases. | https://astronomy.com/magazine/ask-astro/2018/06/big-stars |

8/8/2020 12:00 PM | Work has begun on an ambitious new mission that will carry a cutting-edge 8.4-foot (2.5-meter) telescope high into the stratosphere on a balloon. Tentatively planned to launch in December 2023 from Antarctica, ASTHROS (short for Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths) will spend about three weeks drifting on air currents above the icy southern continent and achieve several firsts along the way. | https://www.jpl.nasa.gov/news/news.php?feature=7712 |
8/8/2020 2:00 PM | Ancient light from the Big Bang has revealed a precise new estimate for the universe’s age: 13.77 billion years, give or take 40 million years. The new estimate, based on data from an array of telescopes in the Chilean Atacama Desert, also weighs in on one of the most important disagreements in astrophysics: How fast is the universe expanding? | https://www.livescience.com/universe-expansion-atacama-hubble-constant-measurement.html |

8/9/2020 12:00 PM | Japan’s Hayabusa2 spacecraft is nearly home. Having collected samples from the asteroid Ryugu last year, the spacecraft is just months away from returning them to Earth. The samples contain material that likely dates back to the dawn of the solar system, 4.6 billion years ago. They could provide fresh insights into how celestial bodies came to be and even how life on Earth began. But before all that, there is the small matter of getting Hayabusa2’s precious cargo down from the harsh vacuum of space and safely into scientists’ hands. | https://www.scientificamerican.com/article/japan-prepares-for-hayabusa2s-daring-return-to-earth/ |
8/9/2020 2:00 PM | The genome of the phylloxera, an insect that caused plagues that devastated European vines in the 19th century, has been deciphered by an international team involving researchers Miquel Barberà and David Martínez, from the Institute for Integrative Systems Biology (I2SysBio), center of the University of Valencia, and the CSIC. | https://phys.org/news/2020-07-genome-phylloxera-devastated-european-vines.html |
8/9/2020 4:00 PM | Even by the standards of quantum physicists, strange metals are just plain odd. The materials are related to high-temperature superconductors and have surprising connections to the properties of black holes. Electrons in strange metals dissipate energy as fast as they’re allowed to under the laws of quantum mechanics, and the electrical resistivity of a strange metal, unlike that of ordinary metals, is proportional to the temperature. | https://phys.org/news/2020-07-quantum-physicists-mystery-strange-metals.html |
8/9/2020 6:00 PM | There are many types of light—some visible and some invisible to the human eye. For example, our eyes and brain don’t have the tools to process ultraviolet light when it hits our eyes, making it invisible. But there is another type of light that is invisible simply because it never reaches our eyes. When light hits certain surfaces, part of it sticks and remains behind rather than being transmitted or scattered away. This type of light is called near-field light. | https://phys.org/news/2020-07-near-field-advances-particle-high-resolution.html |
8/10/2020 8:00 AM | A new study published in the Journal of the Royal Society Interface saw British and Spanish researchers take a deep dive into the combs of Tetragonula, a stingless bee from Southeast Asia and Australia, to understand how, without some sort of comb blueprint, these animals could so consistently create these complex structures. They found that the bizarre spiral shape of their nests, which have long been a source of confusion for scientists, are crafted in a pattern that is similar at a molecular level to crystal development. | https://www.iflscience.com/plants-and-animals/this-stingless-bee-builds-combs-using-the-same-structural-development-that-forms-crystals/ |

8/10/2020 6:00 PM | In 1928, the shy, brilliant physicist Paul Dirac predicted the existence of antimatter. When it was actually discovered 7 years later, Dirac should have become a household name. But his yearning to avoid publicity — he almost turned down the Nobel Prize — discouraged media attention, and he’s known today only among science geeks. | https://astronomy.com/magazine/weirdest-objects/2015/11/8-milky-way-antimatter-fountain |

8/11/2020 4:00 PM | Frequency combs are becoming one of the great enabling technologies of the 21st century. High-precision atomic clocks, and high-precision spectroscopy are just two technologies that have benefited from the development of highly precise frequency combs. However, the original frequency comb sources required a room full of equipment. And it turns out that if you suggest that a room full of delicate equipment is perfect for a commercial application, the development engineer makes a beeline for the nearest exit. | https://phys.org/news/2020-07-silicon-core-fishbone-waveguide-frequency.html |

It’s called the butterfly effect. The big idea is that you’d step out of your time travel machine and accidentally step on a bug. Because this bug doesn’t exist… maybe a frog goes hungry and dies. And maybe that frog was supposed to hop on a sabre-tooth tiger’s face at exactly the right moment so the cave person from which our greatest leader will descend can escape death. Now, because that bug is dead, the cave man didn’t live and our planet is a nuclear wasteland when you return to the “present.” | https://thenextweb.com/science/2020/07/31/quantum-physicists-say-time-travelers-dont-have-to-worry-about-the-butterfly-effect/ |

8/20/2020 10:00 AM | In space, nobody can hear you scream, but with the right equipment, it is possible to detect a roar. That’s what scientists discovered back in 2006 when they began to look for distant signals in the universe using a complex instrument fixed to a huge balloon that was sent to space. The instrument was able to pick up radio waves from the heat of distant stars, but what came through that year was nothing short of astounding. As the instrument listened from a height of about 23 miles (37 kilometers), it picked up a signal that was six-times louder than expected by cosmologists. Because it was too loud to be early stars and far greater than the predicted combined radio emission from distant galaxies, the powerful signal caused great puzzlement. And scientists still don’t know what is causing it, even today. | https://www.space.com/space-roar-loudest-sound-in-the-universe.html |
8/20/2020 12:00 PM | A fossil called Tanystropheus was first described in 1852, and it’s been puzzling scientists ever since. At one point, paleontologists thought it was a flying pterosaur, like a pterodactyl, and that its long, hollow bones were phalanges in the finger that supported the wing. Later on, they figured out that those were elongated neck bones, and that it was a twenty-foot-long reptile with a ten-foot neck: three times as long as its torso. Scientists still weren’t sure if it lived on land or in the water, and they didn’t know if smaller specimens were juveniles or a completely different species—until now. By CT-scanning the fossils’ crushed skulls and digitally reassembling them, researchers found evidence that the animals were water-dwelling, and by examining the growth rings in bones, determined that the big and little Tanystropheus were separate species that could live alongside each other without competing because they hunted different prey. | https://phys.org/news/2020-08-fossil-mystery-super-long-necked-reptiles-ocean.html |

8/20/2020 4:00 PM | Our solar system’s comets are believed to have delivered a wealth of material to early Earth. Among the icy visitors’ suspected gifts were rare gases, small amounts of water, and organic material — all of which could have helped terrestrial life form and evolve. But while ancient Earth received only a moderate influx of comets, any planets around young nearby star Eta Corvi are likely raking in cometary currency. | https://astronomy.com/magazine/news/2020/07/is-eta-corvi-a-window-into-our-past |

8/21/2020 2:00 PM | Supermassive black holes dot our universe, monstrous gravity wells that bind galaxies together and wreath themselves in whirling cocoons of dust that emit bright X-ray beams. Sometimes, bright columns of matter burst up from their poles, forming jets visible across space. And now some scientists suspect these gravitational monsters might host blanets — tens of thousands of them. Nope, that’s not a typo: Scientists suggest calling these black hole planets by the name “blanets.” | https://www.space.com/black-hole-planets-blanets.html |

8/26/2020 8:00 AM | The calcium in our bones and teeth likely came from stars exploding in supernovas and scattering this mineral across the universe in massive quantities, according to a new study. In fact, half of the calcium in the universe likely came from calcium-rich supernovae. But these explosions have turned out to be incredibly rare events that scientists have had difficulty observing and analyzing, so they weren’t sure how the calcium was created. Explosions and mergers of stars are also known to create other heavy elements, like gold and platinum.

8/27/2020 8:00 AM | A new study, published this week in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035. High temperatures in the Arctic during the last interglacial—the warm period around 127,000 years ago—have puzzled scientists for decades. Now the UK Met Office’s Hadley Centre climate model has enabled an international team of researchers to compare Arctic sea ice conditions during the last interglacial with present day.

8/27/2020 6:00 PM | Physicists have long sought to understand the irreversibility of the surrounding world and have credited its emergence to the time-symmetric, fundamental laws of physics. According to quantum mechanics, the final irreversibility of conceptual time reversal requires extremely intricate and implausible scenarios that are unlikely to spontaneously occur in nature. Physicists had previously shown that while time-reversibility is exponentially improbable in a natural environment—it is possible to design an algorithm to artificially reverse a time arrow to a known or given state within an IBM quantum computer. However, this version of the reversed arrow-of-time only embraced a known quantum state and is therefore compared to the quantum version of pressing rewind on a video to “reverse the flow of time.” | https://phys.org/news/2020-08-time-reversal-unknown-quantum-state.html |

8/30/2020 12:00 PM | The extinction of prehistoric megafauna like the woolly mammoth, cave lion, and woolly rhinoceros at the end of the last ice age has often been attributed to the spread of early humans across the globe. Although overhunting led to the demise of some species, a study appearing August 13 in the journal Current Biology found that the extinction of the woolly rhinoceros may have had a different cause: climate change. By sequencing ancient DNA from 14 of these megaherbivores, researchers found that the woolly rhinoceros population remained stable and diverse until only a few thousand years before it disappeared from Siberia, when temperatures likely rose too high for the cold-adapted species. | https://phys.org/news/2020-08-ancient-genomes-woolly-rhinos-extinct.html |

9/2/2020 8:00 AM | As the fiery emissary streaked across the skies of Costa Rica, an unearthly mix of orange and green, Marcia Campos Muñoz was in her pajamas, watching TV on the couch. It was 23 April 2019, a bit past 9 p.m., when she heard a foreboding rumble. Heart racing, she tiptoed outside to calm her barking dog, Perry, and to check on the cow pastures ringing her small house in Aguas Zarcas, a village carved out of Costa Rica’s tropical rainforest. Nothing. She ducked back inside, just before a blast on the back terrace rattled the house to its bones. | https://www.sciencemag.org/news/2020/08/unusual-meteorite-more-valuable-gold-may-hold-building-blocks-life |

9/2/2020 12:00 PM | In the 2014 movie Interstellar, astronauts investigate planets orbiting a supermassive black hole as potential homes for human life. A supermassive black hole warps surrounding space-time, according to Einstein’s theory of general relativity, and at least one of the planets in the movie, called Miller’s planet, experienced time passing at a slowed-down rate. For each hour the astronauts spent on the planet, several years passed outside the black hole’s influence. | https://astronomy.com/news/2019/10/could-life-survive-on-a-planet-orbiting-a-black-hole |

9/3/2020 12:00 PM | In April of this year, NASA nudged the Cassini spacecraft into an orbit that took it through a narrow gap between Saturn’s innermost ring (the D-ring) and the gas giant itself. Over the next few months, Cassini skimmed the upper atmosphere of the ringed planet nearly two dozen times. During 11 of those orbits, Cassini’s Radio and Plasma Wave Science (RPWS) instrument took unprecedented measurements of Saturn’s ionosphere — a shell of charged particles that surrounds the planet and shields it from incoming solar radiation and cosmic rays. | https://astronomy.com/news/2017/12/saturns-ionosphere |
9/3/2020 2:00 PM | Immediately after the Big Bang, every particle in the universe traveled at the speed of light. And then the Higgs field—an invisible and sticky medium that permeates the entire universe—fell into place. Some particles didn’t even notice the shift. But others felt a sudden jolt as their point-like bodies burgeoned with something completely new: mass. | https://www.symmetrymagazine.org/article/a-new-view-of-the-higgs-boson |
9/3/2020 4:00 PM | The remains of several timber circles constructed over 4,500 years ago have been discovered at the Perdigões complex archaeological site in Portugal.

9/5/2020 8:00 AM | Is there life on a distant planet? One way astronomers are trying to find out is by analyzing the light that is scattered off a planet’s atmosphere. Some of that light, which originates from the stars it orbits, has interacted with its atmosphere, and provides important clues to the gases it contains. If gases like oxygen, methane or ozone are detected, that could indicate the presence of living organisms. Such gases are known as biosignatures. A team of scientists from EPFL and Tor Vergata University of Rome has developed a statistical model that can help astronomers interpret the results of the search for these “signs of life.” | https://phys.org/news/2020-08-tool-future-life-exoplanets.html |

9/5/2020 12:00 PM | A small but evolving dent in Earth’s magnetic field can cause big headaches for satellites. Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field—called the South Atlantic Anomaly, or SAA—allows these particles to dip closer to the surface than normal. Particle radiation in this region can knock out onboard computers and interfere with the data collection of satellites that pass through it—a key reason why NASA scientists want to track and study the anomaly. | https://phys.org/news/2020-08-nasa-track-slowly-dent-earth.html |
9/5/2020 2:00 PM | Imagine reading by the light of an exploded star, brighter than a full moon—it might be fun to think about, but this scene is the prelude to a disaster when the radiation devastates life as we know it. Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth’s rock record could confirm this scenario. | https://phys.org/news/2020-08-stars-mass-extinction-earth.html |

Under appropriate conditions, we can measure either wave-like or particle-like behavior for photons — the fundamental quantum of light — confirming the dual, and very weird, nature of reality. | https://www.forbes.com/sites/startswithabang/2020/08/19/in-quantum-physics-even-humans-act-as-waves/ |
9/13/2020 2:00 PM | Galactic halos are both more massive and more complicated than scientists realized, according to new observations from the Hubble Space Telescope. The venerable telescope turned its sights on the neighboring Andromeda galaxy using dozens of different quasars to map the galactic halo. Andromeda, more formally known as M31, is a spiral-shaped galaxy about the same size of the Milky Way galaxy we live in, with about 1 trillion stars. Cosmically, it’s right next door, just 2.5 million light-years away, which means that Hubble can study its halo in unprecedented detail. | https://www.space.com/andromeda-galaxy-halo-hubble-telescope-discovery.html |
9/13/2020 4:00 PM | The last time we saw NASA’s Mars 2020 Perseverance rover mission was on July 30, 2020, as it disappeared into the black of deep space on a trajectory for Mars. But with NASA’s Eyes on the Solar System, you can follow in real time as humanity’s most sophisticated rover—and the Ingenuity Mars Helicopter traveling with it—treks millions of miles over the next six months to Jezero Crater. | https://phys.org/news/2020-08-nasa-perseverance-rover-real-mars.html |
9/13/2020 6:00 PM | The LHCb experiment at CERN has developed a penchant for finding exotic combinations of quarks, the elementary particles that come together to give us composite particles such as the more familiar proton and neutron. In particular, LHCb has observed several tetraquarks, which, as the name suggests, are made of four quarks (or rather two quarks and two antiquarks). Observing these unusual particles helps scientists advance our knowledge of the strong force, one of the four known fundamental forces in the universe. At a CERN seminar held virtually on 12 August, LHCb announced the first signs of an entirely new kind of tetraquark with a mass of 2.9 GeV/c²: the first such particle with only one charm quark. | https://phys.org/news/2020-08-open-charm-tetraquark.html |
9/14/2020 8:00 AM | For all of its technological prowess, NASA can still have a hard time sending data from distant space missions back down to Earth and vice versa. It’s part of the reason that images and footage from space are often so grainy. But with new laser facilities coming online next year, NASA plans to beam messages up and down from Earth using infrared lasers, vastly improving the space agency’s bandwidth, according to a NASA press release. | https://futurism.com/the-byte/nasa-facility-beam-messages-space-lasers |
9/14/2020 10:00 AM | Scientists studying leaves from a 23-million-year-old forest have for the first time linked high levels of atmospheric carbon dioxide with increased plant growth, and the hot climate off the time. The finding adds to the understanding of how rising CO2 heats the earth, and how the dynamics of plant life could shift within decades, when CO2 levels may closely mirror those of the distant past. | https://phys.org/news/2020-08-fossil-high-atmospheric-carbon-spurred.html |
9/14/2020 12:00 PM | New simulations show that NASA’s Nancy Grace Roman Space Telescope will be able to reveal myriad rogue planets – freely floating bodies that drift through our galaxy untethered to a star.

9/14/2020 2:00 PM | For several years, astronomers and cosmologists have theorized about the existence of an additional planet with a mass 10 times greater than that of Earth, situated in the outermost regions of the solar system. This hypothetical planet, dubbed Planet 9, could be the source of gravitational effects that would explain the unusual patterns in the orbits of trans-Neptunian objects (TNOs) highlighted by existing cosmological data. TNOs are celestial bodies that orbit the sun and are located beyond Neptune. | https://phys.org/news/2020-08-planet-primordial-black-hole.html |
9/14/2020 4:00 PM | With the help of two extremely bright quasars located more than 7 billion light-years away, researchers recently bolstered the case for quantum entanglement — a phenomenon Einstein described as “spooky action at a distance” — by eliminating one classical alternative: The freedom-of-choice loophole. | https://astronomy.com/news/2018/08/distant-quasars-confirm-quantum-entanglement |

These habitats range from relatively simple, flat surfaces to highly complex three-dimensional structures. | https://phys.org/news/2020-08-nooks-crannies-critters-complexity-habitats.html |
9/15/2020 8:00 AM | One of the worst extinction events in Earth’s history may have been triggered by a supernova, the violent death of a distant star. About 75% of all species on Earth died out at the end of the Devonian Period, nearly 360 million years ago. Rocks from this era preserve many thousands of spores that appear to be scorched by ultraviolet (UV) radiation, indicating that something went seriously wrong with our protective ozone layer. | https://www.space.com/supernova-caused-earth-mass-extinction-devonian.html |

9/16/2020 10:00 AM | Once in a while, over the history of life, a new trait evolves that leads to an explosion of diversity in a group of organisms. Take wings, for instance. Every group of animals that evolved them has spun off into a host of different species—birds, bats, insects and pterosaurs. Scientists call these “key innovations.” | https://phys.org/news/2020-08-biologists-gene-critical-columbines-iconic.html |

9/16/2020 2:00 PM | A nearby star, the host of two (and possibly three) planets, was initially thought to be quiet and boring. These attributes are sought-after as they create a safe environment for their planets, especially those that may be in what scientists call “the habitable zone” where liquid water could exist on their surfaces and life might be possible. But astronomers at Arizona State University have announced that this nearby star turns out to be not so tame after all. | https://phys.org/news/2020-08-planets-safe-stellar-flares-thought.html |
9/16/2020 4:00 PM | White dwarfs are some of the strangest objects in the universe.

Otherwise, his fish story might have turned out even stranger. Instead of two feet, some fish have two sexes. Some change from male to female, and vice versa. And it’s really not that unusual — as many as 500 fish species can change sex in adulthood, along with plenty other animals and plants. | https://www.discovermagazine.com/planet-earth/how-stress-climate-and-trauma-can-trigger-sex-changes-in-nature |
9/18/2020 4:00 PM | Black holes are some of the strangest and most fascinating objects in outer space. They’re extremely dense, with such strong gravitational attraction that even light cannot escape their grasp if it comes near enough. Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term “black hole” was coined many years later in 1967 by American astronomer John Wheeler. After decades of black holes being known only as theoretical objects, the first physical black hole ever discovered was spotted in 1971. | https://www.space.com/15421-black-holes-facts-formation-discovery-sdcmp.html |

Although massive and often active, these objects are still difficult to “see” in the traditional sense of the word for many reasons. But now, using the uniquely sharp “vision” afforded by the National Science Foundation’s Very Long Baseline Array (VLBA), astronomers have spotted for the first time a pair of supermassive black holes orbiting each other in a galaxy 750 million light-years away. | https://astronomy.com/news/2017/06/orbiting-smbhs |

Without zero, there’s no calculus, which means no modern engineering or automation. Without zero, much of our modern world literally falls apart. Humanity’s discovery of zero was “a total game changer … equivalent to us learning language,” says Andreas Nieder, a cognitive scientist at the University of Tübingen in Germany.

9/24/2020 12:00 PM | Ceres, the closest dwarf planet to Earth, may be wrinkling as it shrinks, a new study finds. With a width of about 585 miles (940 kilometers), Ceres is both a dwarf planet and the largest member of the asteroid belt located between Mars and Jupiter. Previous research found that the dwarf planet was not made up solely of rock, but composed partly of both icy and rocky material.

9/24/2020 6:00 PM | Glass is amorphous in nature—its atomic structure does not involve the repetitive arrangement seen in crystalline materials. But occasionally, it undergoes a process called devitrification, which is the transformation of a glass into a crystal—often an unwanted process in industries. The dynamics of devitrification remain poorly understood because the process can be extremely slow, spanning decades or more. | https://phys.org/news/2020-09-devitrification-demystified.html |
9/25/2020 8:00 AM | The camera core for the future Vera C. Rubin Observatory has snapped its first test photos, setting a new world record for the largest single shot by a giant digital camera. The imaging sensor array, which comprises the focal plane for Vera Rubin’s SUV-sized digital camera, snapped the 3,200-megapixel images during recent tests at the Department of Energy’s (DOE) SLAC National Accelerator Laboratory in California.

9/25/2020 12:00 PM | The search for habitable exoplanets spans far and wide, pushing the limits of what our modern telescopes are capable of. But rest assured that we aren’t ignoring what’s in our own backyard. Researchers have kept diligent eyes on Alpha Centauri, the closest system to Earth that happens to house Sun-like stars. And now, a comprehensive study published in Research Notes of the AAS clears Alpha Centauri’s two brightest stars of a crucial habitability factor: dangerous X-ray radiation. | https://astronomy.com/news/2018/06/alpha-centauri-system-could-have-favorable-conditions-for-life |
9/25/2020 2:00 PM | An amateur astronomer has discovered a kilometer-wide asteroid that would create global devastation if it were to hit the Earth. Thankfully that won’t happen: the asteroid will miss our planet by 40 million kilometers as it passes on 10 September 2020, more than 100 times the distance between Earth and the Moon. But the fact that this relatively large near-Earth object, or NEO, wasn’t detected until now serves as a reminder that there’s much work to be done when it comes to defending our planet from dangerous asteroids. | https://www.planetary.org/articles/planetary-society-grant-winner-discovers-large-asteroid |
9/25/2020 4:00 PM | For the first time, climate scientists have compiled a continuous, high-fidelity record of variations in Earth’s climate extending 66 million years into the past.

9/25/2020 6:00 PM | In one of the most complex cosmic dances astronomers have yet spotted, three rings of gas and dust circle a trio of stars. The star system GW Orionis, located about 1,300 light-years away in the constellation Orion, includes a pair of young stars locked in a close do-si-do with a third star making loops around both. Around all three stars is a broken-apart disk of dust and gas where planets could one day form. Unlike the flat disk that gave rise to the planets in our solar system, GW Orionis’ disk consists of three loops, with a warped middle ring and an inner ring even more twisted at a jaunty angle to the other two. | https://www.sciencenews.org/article/weird-warped-planet-forming-disk-orbits-three-stars |
9/26/2020 8:00 AM | A quark is an elementary subatomic particle; three of them make up a proton or a neutron. Some scientists base the suggested existence of quark stars (which would be made of quarks instead of complete protons or neutrons) on a famous conjecture by the eminent Princeton physicist Ed Witten. He said the true ground state of matter (in the sense of the lowest energy per particle) consists of a mixture of roughly equal numbers of up, down, and strange quarks, with enough electrons thrown in to ensure that this soup is electrically neutral. Although scientists have never demonstrated this conjecture to be true, many theoretical astrophysicists have run with it, imagining the potential implications for the heavens. | https://astronomy.com/magazine/ask-astro/2013/04/quark-star |

9/26/2020 2:00 PM | Around 100,000 years ago, the climate changed abruptly and the environment of Central-Eastern Europe shifted from forested to open steppe/taiga habitat, promoting the dispersal of wooly mammoth, wooly rhino and other cold adapted species from the Arctic. Neanderthals living in these territories suffered severe demographic contractions due to the new ecological conditions and only returned to the areas above 48° N latitude during climatic ameliorations. However, in spite of the discontinuous settlement, specific bifacial stone tools persisted in Central-Eastern Europe from the beginning of this ecological shift until the demise of the Neanderthals. | https://phys.org/news/2020-09-oldest-neanderthal-dna-central-eastern-europe.html |

9/26/2020 6:00 PM | Lasing—the emission of a collimated light beam of light with a well-defined wavelength (color) and phase—results from a self-organization process, in which a collection of emission centers synchronizes itself to produce identical light particles (photons). A similar self-organized synchronization phenomenon can also lead to the generation of coherent vibrations—a phonon laser, where phonon denotes, in analogy to photons, the quantum particles of sound. | https://phys.org/news/2020-09-phonon-laser-coherent-vibrations-self-breathing.html |

It rapidly journeys across the sky at 800,000 mph (1.3 million kilometers per hour). But more interesting than that, HD 140283 — or Methuselah as it’s commonly known — is also one of the universe’s oldest known stars. | https://www.space.com/how-can-a-star-be-older-than-the-universe.html |
9/27/2020 2:00 PM | Until 1920, humans had no real sense of how the sun and stars create their vast amounts of energy. Then, in October of that year, Arthur Stanley Eddington, an English astrophysicist, penned an essay elegantly titled “ The Internal Constitution of the Stars.” “A star is drawing on some vast reservoir of energy by means unknown,” he wrote. “This reservoir can scarcely be other than the sub-atomic energy which, it is known, exists abundantly in all matter; we sometimes dream that man will one day learn how to release it and use it for his service.” | https://www.wired.com/story/fusion-energy-iter-reactor-ready-to-shine/ |

9/27/2020 6:00 PM | First, it’s still possible the universe is finite. All we know for sure (mostly for sure) is that it’s bigger than we can observe, essentially because the farthest edges of the universe we can see don’t look like edges. The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. | https://astronomy.com/news/2020/03/is-the-universe-infinite |

9/28/2020 6:00 PM | More than 230 years ago astronomer William Herschel discovered the planet Uranus and two of its moons. Using the Herschel Space Observatory, a group of astronomers led by Örs H. Detre of the Max Planck Institute for Astronomy now has succeeded in determining physical properties of the five main moons of Uranus. The measured infrared radiation, which is generated by the Sun heating their surfaces, suggests that these moons resemble dwarf planets like Pluto.

Recently, with new telescopic technologies, astronomers have made big strides toward finding all our stellar neighbors. Knowing the stellar cast, they can then project this information into the galaxy at large to help us learn how stars, and even planets, are born and live out their lives. As a result of these studies, astronomers are now learning how our own Sun fits into the overall picture. | https://astronomy.com/magazine/2019/10/meet–the-stars-next-door |

10/4/2020 6:00 PM | The toughest organisms on Earth, called extremophiles, can survive extreme conditions like extreme dryness (desiccation), extreme cold, space vacuum, acid, or even high-level radiation. So far, the toughest of all seems to be the bacterium Deinococcus radiodurans—able to survive doses of radiation a thousand times greater than those fatal to humans. But to this date, scientists remained puzzled by how radio-resistance could have evolved in several organisms on our planet, naturally protected from solar radiation by its magnetic field. While some scientists suggest that radio-resistance in extremophile organisms could have evolved along with other kinds of resistance, such as resistance to desiccation, a question remained: which genes are specifically involved in radio-resistance? | https://phys.org/news/2020-09-evolution-radio-resistance-complicated-previously-thought.html |

10/10/2020 2:00 PM | Unlike secondary batteries that need to be recharged, fuel cells are a type of eco-friendly power generation system that produce electricity directly from electrochemical reactions using hydrogen as fuel and oxygen as oxidant. There are various types of fuel cells, differing in operating temperatures and electrolyte materials. Solid oxide fuel cells (SOFCs), which use a ceramic electrolyte, are receiving increasing attention. Because they operate at high temperatures around 700 degrees Celsius, they offer the highest efficiency among fuel cell types, and can also be used to produce hydrogen by steam decomposition. For the commercialization of this technology, further improvement of cell performance is necessary, and novel high-temperature catalyst materials are highly anticipated. | https://phys.org/news/2020-09-high-performance-single-atom-catalysts-high-temperature-fuel.html |
10/10/2020 4:00 PM | Using observations made with the Gran Telescopio Canarias (GTC), at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands), and with the ATACAMA Large Millimeter/submillimetre Array (ALMA), in Chile, astronomers have found the first galaxy whose ultraviolet luminosity is comparable to that of a quasar. The galaxy, called BOSS-EUVLG1, has a red-shift of 2.47. This is a measure of the reddening of the light coming from the galaxy, and can be used to find its distance: the further away the galaxy, the greater the value. For BOSS-EUVLG1, the value of 2.47 means that the galaxy has been observed when the universe was some 2000 million years old, around 20% of its present age. | https://phys.org/news/2020-09-astronomers-galaxy-ultraviolet-luminosity-quasar.html |

10/12/2020 6:00 PM | The Large Hadron Collider (LHC) is renowned for the hunt for and discovery of the Higgs boson, but in the 10 years since the machine collided protons at an energy higher than previously achieved at a particle accelerator, researchers have been using it to try to hunt down an equally exciting particle: the hypothetical particle that may make up an invisible form of matter called dark matter, which is five times more prevalent than ordinary matter and without which there would be no universe as we know it. The LHC dark-matter searches have so far come up empty handed, as have non-collider searches, but the incredible work and skill put by the LHC researchers into finding it has led them to narrow down many of the regions where the particle may lie hidden—necessary milestones on the path to a discovery. | https://phys.org/news/2020-09-ground-dark.html |

10/15/2020 6:00 PM | Quantum mechanics arose in the 1920s, and since then scientists have disagreed on how best to interpret it. Many interpretations, including the Copenhagen interpretation presented by Niels Bohr and Werner Heisenberg, and in particular, von Neumann-Wigner interpretation, state that the consciousness of the person conducting the test affects its result. On the other hand, Karl Popper and Albert Einstein thought that an objective reality exists. Erwin Schrödinger put forward the famous thought experiment involving the fate of an unfortunate cat that aimed to describe the imperfections of quantum mechanics. | https://phys.org/news/2020-10-quantum-mechanics-reality-person.html |

A new study has found the most commonly-theorized origin of gold — collisions between neutron stars — can’t explain gold’s abundance either. So where’s the gold coming from? There are some other possibilities, including supernovas so intense they turn a star inside out. Unfortunately, even such strange phenomena can’t explain how blinged out the local universe is, the new study finds. | https://www.space.com/where-did-gold-come-from.html |
10/16/2020 4:00 PM | The moon may be hiding the scientific key to the mysterious past of our neighboring world, Venus. Scientists think that Earth and Venus were once awfully similar.

10/18/2020 8:00 AM | At around 60 million light-years from Earth, the Great Barred Spiral Galaxy, NGC 1365, is captured beautifully in this image by the NASA/ESA Hubble Space Telescope. Located in the constellation of Fornax (the Furnace), the blue and fiery orange swirls show us where stars have just formed and the dusty sites of future stellar nurseries. | https://phys.org/news/2020-10-hubble-swirls-stars.html |
10/18/2020 10:00 AM | Black holes are perhaps the strangest, least-understood objects in our universe. With so much potential — being linked to everything from wormholes to new baby universes — they have sucked in physicists for decades. | https://www.space.com/bizarre-charged-black-holes.html |
10/18/2020 12:00 PM | Bill Nye, everybody’s favorite “science guy,” has teamed up with 4-H to take students to Mars (figuratively speaking.) 4-H is a network of youth organizations across the United States that provides educational opportunities. Every year, 4-H hosts the 4-H STEM (science, technology, engineering and mathematics) Challenge (formerly known as 4-H National Youth Science Day). This year’s challenge — Mars Base Camp — marks the 13th annual event to date, and it will explore human space exploration and humanity’s efforts to reach the Red Planet. | https://www.space.com/bill-nye-4-h-mars-base-camp.html |
10/18/2020 2:00 PM | Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics and particle sorting. | https://phys.org/news/2020-10-nanoscale-machines.html |
10/18/2020 4:00 PM | Only one in a hundred million stars makes the cut to be classified a Wolf-Rayet: ferociously bright, hot stars doomed to imminent collapse in a supernova explosion leaving only a dark remnant, such as a black hole. Rarest of all, even among Wolf-Rayets, are elegant binary pairs that, if the conditions are right, are able to pump out huge amounts of carbon dust driven by their extreme stellar winds. As the two stars orbit one another, the dust gets wrapped into a beautiful glowing sooty tail. Just a handful of these sculpted spiral plumes has ever been discovered. | https://phys.org/news/2020-10-eye-stellar-cyclone-bizarre-secrets.html |
10/18/2020 6:00 PM | Telescopes have captured the rare light flash from a dying star as it was ripped apart by a supermassive black hole. This rarely seen “tidal disruption event” — which creates spaghettification in stars as they stretch and stretch – is the closest such known event to happen, at only 215 million light-years from Earth. | https://www.space.com/black-hole-star-death-spaghettification |

10/19/2020 10:00 AM | Researchers using Cassini’s RPWS data showed that Saturn has a cold, compact, and dynamic ionosphere with a density that can vary by as much as a factor of 100. Furthermore, the researchers found that Saturn’s enormous and opaque rings cast ionosphere-altering shadows over the planet, and they may even generate “ring rain.” | https://astronomy.com/news/2017/12/saturns-ionosphere |
10/19/2020 12:00 PM | Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the strongest, thinnest material known to man, it is also an excellent conductor of heat and electricity. | https://phys.org/news/2020-10-stacking-graphene-rare-magnetism.html |
10/19/2020 2:00 PM | In a recently published study, a team of researchers led by the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) at Monash university suggests an innovative method to analyse gravitational waves from neutron star mergers, where two stars are distinguished by type (rather than mass), depending on how fast they’re spinning. | https://phys.org/news/2020-10-method-analyse-densest-star-universe.html |
10/19/2020 4:00 PM | A team of physicists led by Professor Patrick Windpassinger at Johannes Gutenberg University Mainz (JGU) has successfully transported light stored in a quantum memory over a distance of 1.2 millimeters. They have demonstrated that the controlled transport process and its dynamics has only little impact on the properties of the stored light. The researchers used ultra-cold rubidium-87 atoms as a storage medium for the light as to achieve a high level of storage efficiency and a long lifetime. | https://phys.org/news/2020-10-physicists-successfully.html |
10/19/2020 6:00 PM | At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers have measure how much dark matter there is around galaxies, and have found that it varies between 10 and 300 times the quantity of visible matter. However, a few years ago, the discovery of a very diffuse object, named Dragonfly 44, changed this view. It was found that this galaxy has 10,000 times more dark matter than the stars. Taken back by this finding, astronomers have made efforts to see whether this object is really anomalous, or whether something went wrong in the analysis of the observations. Now we have the answer. | https://phys.org/news/2020-10-puzzle-strange-galaxy-dark.html |
10/20/2020 8:00 AM | Bill Nye has had it with flat-Earthers and other science deniers. While humanity is landing robots on Mars and breaking open the mysteries of the universe, there continues a social trend of “science denialism.” From opposition to handwashing in the 1800s to modern climate deniers, anti-maskers and “flat-Earthers,” or people who believe that planet Earth is actually flat ( it is not), “anti-science” movements aren’t new, but they are a problem facing us all today, according to Nye.. | https://www.space.com/bill-nye-speaks-out-flat-earthers-science-denial |

10/20/2020 12:00 PM | Researchers at Pacific Northwest National Laboratory (PNNL) have increased the conductivity of copper wire by about five percent. That may seem like a small amount but it can make a big difference in motor efficiency. Higher conductivity also means that less copper is needed for the same efficiency, which can reduce the weight and volume of various components that are expected to power our future electric vehicles. | https://phys.org/news/2020-10-copper-higher-efficiency-electric-motors.html |
10/20/2020 2:00 PM | There is an old saying, “If rubber is the material that opened the way to the ground, aluminum is the one that opened the way to the sky.” New materials were always discovered at each turning point that changed human history. Materials used in memory devices are also drastically evolving with the emergence of new materials such as doped silicon materials, resistance changing materials, and materials that spontaneously magnetize and polarize. How are these new materials made? A research team from POSTECH has revealed the mechanism behind making materials used in new memory devices by using artificial intelligence. | https://phys.org/news/2020-10-materials-ai.html |
10/20/2020 4:00 PM | Once a black hole forms, its intense gravitational field produces a surface beyond which even light cannot escape, and it appears black to outsiders. All the details of the complex mix of matter and energy in its past are lost, leaving it so simple that it can be completely described by just three parameters: mass, spin, and electric charge. Astronomers can measure the masses of black holes in a relatively straightforward way by watching how matter moves in their vicinity (including other black holes) under the influence of their gravitational fields. | https://phys.org/news/2020-10-supermassive-black-hole-milky.html |
10/20/2020 6:00 PM | The dominant thinking in evolution focuses on inheritance between parent and offspring – or ‘vertical gene transfer (VGT)’. But now scientists are paying more attention to ‘horizontal gene transfer (HGT)’: the transmission of DNA other than from parent to offspring, as this transfer can tell us about the evolution of a number of other organisms such as bacteria. It can also help us to better understand antibiotic resistance. | https://phys.org/news/2020-10-world-microorganisms-evolution.html |

10/21/2020 10:00 AM | Scientists in Australia have stumbled across an unusual way to observe color that had previously gone unnoticed. To create the effect, researchers attached a very thin film of one material to another, larger sample. The electric field (an invisible force created by the attraction and repulsion of electrical charges) is very strong where the two materials are connected. | https://phys.org/news/2020-10-dont-hidden-colours-coincidence.html |
10/21/2020 12:00 PM | Over the past few years, a growing number of researchers worldwide has been conducting studies investigating the properties and features of so-called twisted van der Waals (vdW) materials.

10/21/2020 4:00 PM | For a tiny embryo to develop into an adult organism, its cells must develop in precise patterns and interact with their neighbors in carefully orchestrated ways. To create complex tissues and organs—from the pattern of rods and cones in the retina to the Byzantine filtration systems of the kidney—all these developing cells must constantly answer a fundamental but surprisingly difficult question: Where am I? | https://phys.org/news/2020-10-developmental-illuminate-regenerative-medicine.html |
10/21/2020 6:00 PM | In a changing climate, understanding how organisms respond to stress conditions is increasingly important.

10/22/2020 8:00 AM | At first glance the apparently barren expanses of the Sahel and Sahara deserts feature little greenery, but detailed satellite imagery combined with computer deep learning has revealed a different picture. In fact, some 1.8 billion trees dot parts of the West African Sahara and Sahel deserts and so-called sub-humid zone, a previously uncounted bounty that overturns previous assumptions about such habitats, researchers say. | https://phys.org/news/2020-10-barren-millions-trees-dot.html |
10/22/2020 10:00 AM | For more than a decade, the American public has been fascinated with string theory.

10/23/2020 10:00 AM | An international group of astronomers, led by Martin Schlecker of the Max Planck Institute for Astronomy, has found that the arrangement of rocky, gaseous and icy planets in planetary systems is apparently not random and depends on only a few initial conditions. The study is based on a new simulation that tracks the evolution of planetary systems over several billion years. Planetary systems around sun-like stars, which produce in their inner regions super-Earths with low water and gas content, very often form a planet comparable to our Jupiter on an outer orbit. Such planets help to keep potentially dangerous objects away from the inner regions. | https://phys.org/news/2020-10-simulations-reveal-rocky-super-earths-thin.html |
10/23/2020 12:00 PM | Four-and-a-half billion years ago, Earth’s surface was a menacing, hot mess. Long before the emergence of life, temperatures were scorching, and the air was toxic. Plus, as a mere toddler, the Sun bombarded our planet with violent outbursts of radiation called flares and coronal mass ejections. Streams of charged particles called the solar wind threatened our atmosphere. Our planet was, in short, uninhabitable. | https://www.nasa.gov/feature/earth-and-moon-once-shared-a-magnetic-shield-protecting-their-atmospheres |

10/24/2020 6:00 PM | Researchers at Tufts University have found that those distinctly funky smells from cheese are one way that fungi communicate with bacteria, and what they are saying has a lot to do with the delicious variety of flavors that cheese has to offer. The research team found that common bacteria essential to ripening cheese can sense and respond to compounds produced by fungi in the rind and released into the air, enhancing the growth of some species of bacteria over others. The composition of bacteria, yeast and fungi that make up the cheese microbiome is critical to flavor and quality of the cheese, so figuring out how that can be controlled or modified adds science to the art of cheese making. | https://phys.org/news/2020-10-funky-cheese-microbes.html |

10/27/2020 10:00 AM | Reinfection, in which an individual is subject to multiple, distinct infections from the same virus species throughout their lifetime, is a salient feature of many respiratory viruses. Indeed, the persistence and ubiquity in human society of common respiratory viruses—including influenza viruses, respiratory syncytial virus (RSV), rhinovirus, and the endemic coronaviruses—are largely due to their ability to produce repeat infection. Since the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the ongoing coronavirus disease 2019 (COVID-19) pandemic, a critical concern has been whether humans will experience reinfections with this pathogen, which might enable it to become endemic. | https://science.sciencemag.org/content/early/2020/10/13/science.abe5960 |

10/29/2020 4:00 PM | Ants are one of the most successful groups of animals on the planet, occupying anywhere from temperate soil to tropical rainforests, desert dunes and kitchen counters. They’re social insects and their team-working abilities have long since been identified as one of the key factors leading to their success. Ants are famously able to lift or drag objects many times their own weight and transport these objects back to their colony. But with previous research having focused on the social aspects of an ant colony, looking at an individual ant has been somewhat neglected. | https://phys.org/news/2020-10-flight-huge-benefits-ants.html |

10/30/2020 6:00 PM | Life on Earth has a long, but also an extremely turbulent history. On more than one occasion, the majority of all species became extinct and an already highly developed biodiversity shrank to a minimum again, changing the course of evolution each time. The most extensive mass extinction took place about 252 million years ago. It marked the end of the Permian Epoch and the beginning of the Triassic Epoch. About three quarters of all land life and about 95 percent of life in the ocean disappeared within only a few thousand years. | https://phys.org/news/2020-10-driver-largest-mass-extinction-history.html |

11/3/2020 6:00 PM | Black holes are powerful engines of pure gravity, capable of pulling on objects so intensely that they can’t possibly escape. When those objects near the event horizon, they’re accelerated to incredible velocities. Now, some physicists are suggesting harnessing the gravitational pull of black holes to create ferocious particle accelerators. The trick, the new study finds, is to carefully set everything up so that particles don’t get lost forever in the insatiable black hole. This new insight may help us identify black holes from the streams of particles blasting away from them. | https://www.space.com/black-holes-transformed-into-particle-accelerators |

11/7/2020 4:00 PM | The loss of huge ice masses can contribute to the warming that is causing this loss and further risks. A new study now quantifies this feedback by exploring long-term if-then scenarios. If the Arctic summer sea ice were to melt completely, a scenario that is likely to become reality at least temporarily within this century, this could eventually add roughly 0.2 degrees C to global warming. It is, however, not in addition to IPCC projections of future warming, since these already take the relevant mechanisms into account.

11/10/2020 4:00 PM | The gravitational force in the Universe under which it has evolved from a state almost uniform at the Big Bang until now, when matter is concentrated in galaxies, stars and planets, is provided by what is termed ‘dark matter.” But in spite of the essential role that this extra material plays, we know almost nothing about its nature, behavior and composition, which is one of the basic problems of modern physics. In a recent article in Astronomy & Astrophysics Letters, scientists at the Instituto de Astrofísica de Canarias (IAC)/University of La Laguna (ULL) and of the National University of the North-West of the Province of Buenos Aires (Junín, Argentina) have shown that the dark matter in galaxies follows a ‘maximum entropy’ distribution, which sheds light on its nature. | https://phys.org/news/2020-10-mystery-dark-galaxies.html |
11/10/2020 6:00 PM | There’s an extremely rare metallic asteroid lurking between Mars and Jupiter, and it’s worth more than the entire global economy. Now, the Hubble Space Telescope has given us a closer look at the object, which is worth an estimated $10,000 quadrillion. | https://www.cbsnews.com/news/hubble-space-telescope-rare-asteroid-16-psyche-worth-10000-quadrillion/ |
11/11/2020 8:00 AM | In a first, NASA scientists have spotted a molecule of cyclopropenylidene (C3H2) in the atmosphere of the largest of Saturn’s 62 moons, Titan. Calling this development ‘unexpected’, scientists claim that this is the first time that they have detected this molecule in an atmosphere. They found C3H2 by using a radio telescope observatory in northern Chile known as the Atacama Large Millimeter/submillimeter Array (ALMA). Scientists believe that this carbon-based molecule may be a “precursor to more complex compounds that could form or feed possible life on Titan”. | https://gadgets.ndtv.com/science/news/nasa-scientists-cyclopropenylidene-c3h2-molecule-moon-titan-atmosphere-saturn-alma-2317114 |
11/11/2020 10:00 AM | The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy. Today, this process uses instruments with a grating that spreads out the light from an object by wavelength. This spread-out light is called a spectrum. Every element — and combination of elements — has a unique fingerprint that astronomers can look for in the spectrum of a given object. Identifying those fingerprints allows researchers to determine what it is made of. | https://astronomy.com/magazine/ask-astro/2019/06/how-do-scientists-determine-the-chemical-compositions-of-the-planets-and-stars |
11/11/2020 12:00 PM | When people take antibiotics for one infection, another can swoop in to take its place: the bacterium Clostridioides difficile, which causes severe, recurring colon infections that kill nearly 30,000 people annually in the United States, most over the age of 65. Now, researchers have a new idea for battling C. diff – they have modified yeast to produce and deliver antibodies that defang the bacterium’s two toxins and spur recovery in infected mice. | https://www.sciencemag.org/news/2020/10/antibody-producing-yeast-vanquishes-deadly-gut-infection-mice |

11/11/2020 4:00 PM | At first glance, a pack of wolves has little to do with a vinaigrette. However, a team led by Ramin Golestanian, Director at the Max Planck Institute for Dynamics and Self-Organization, has developed a model that establishes a link between the movement of predators and prey and the segregation of vinegar and oil. They expanded a theoretical framework that until now was only valid for inanimate matter. In addition to predators and prey, other living systems such as enzymes or self-organizing cells can now be described. | https://phys.org/news/2020-10-biological.html |
11/11/2020 6:00 PM | The Kingdom of Saudi Arabia (KSA) is at a crossroads. Recent long-term studies of the area indicate that rising temperatures and evaporation rates will likely further deplete scarce water resources critical to meeting the nation’s agricultural, industrial, and domestic needs; more extreme flooding events could endanger lives, economic vitality, and infrastructure; and a combination of increasing heat and humidity levels may ultimately render the kingdom uninhabitable. Facing a foreboding future, how might the nation adapt to changing climatic conditions and become more resilient to climate extremes? | https://phys.org/news/2020-10-saudi-arabia-humidity-precipitation-extremes.html |

11/13/2020 2:00 PM | Sometime toward the end of the last ice age, a gray wolf gingerly approached a human encampment. Those first tentative steps set his species on the path to a dramatic transformation: By at least 15,000 years ago, those wolves had become dogs, and neither they nor their human companions would ever be the same. But just how this relationship evolved over the ensuin |
