1/1/2020 2:00 PMDanish scientists have managed to extract a complete human DNA sample from a piece of birch pitch more than 5,000 years old, used as a kind of chewing gum, a study revealed.https://phys.org/news/2019-12-flavour-stone-age-chewing-gum-yields-human.html
1/1/2020 4:00 PMInfrared cameras detect people and other objects by the heat they emit. Now, researchers have discovered the uncanny ability of a material to hide a target by masking its telltale heat properties.https://phys.org/news/2019-12-camouflage-quantum-material-infrared-cameras.html
1/1/2020 6:00 PMScientists have captured the birth of a high-speed ice feature for the first time on top of a Russian glacier.https://phys.org/news/2019-12-ice-river-arctic-glacier-seas.html
1/2/2020 8:00 AMThe aquatic larvae of the net-winged midge have the unique ability to move around at ease on rocks in torrential rivers using super-strong suction organs. Powerful modern imaging techniques have now revealed the structure of these organs in intricate detail, providing an insight into how they work so reliably. The findings, reported in the journal BMC Zoology, may inform the development of better man-made suction cups that perform well on a variety of surfaces.https://phys.org/news/2019-12-suction-cups-dont-fall.html

1/2/2020 2:00 PMMany 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 PMParticles 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
1/2/2020 6:00 PMDo supermassive black holes have friends? The nature of galaxy formation suggests that the answer is yes, and in fact, pairs of supermassive black holes should be common in the universe.https://www.space.com/supermassive-black-hole-hiding-milky-way.html
1/3/2020 8:00 AMFootprints discovered over 40 years ago in rocks from Yorkshire have been revealed as potentially the earliest prints from an amphibian yet discovered in the UK, and are potentially the oldest from any four-legged animal.https://www.nhm.ac.uk/discover/news/2019/december/fossils-found-in-yorkshire-are-the-oldest-amphibian-footprints.html

1/3/2020 12:00 PMFor decades, mountain gorillas have been subjected to uncontrolled hunting, disease, habitat loss and the ravages of human conflict. Their numbers plummeted, and they are now considered endangered. But as George Dvorsky of Gizmodo reports, there is encouraging news for these great primates. A new survey has found that the mountain gorilla population has risen to 1,063 confirmed individuals—still a disconcertingly low number, but a sign that conservation efforts are working.https://www.smithsonianmag.com/smart-news/endangered-mountain-gorilla-populations-are-growing-180973808/?

1/3/2020 4:00 PMPhosphine is among the stinkiest, most toxic gases on Earth, found in some of the foulest of places, including penguin dung heaps, the depths of swamps and bogs, and even in the bowels of some badgers and fish. This putrid “swamp gas” is also highly flammable and reactive with particles in our atmosphere.https://phys.org/news/2019-12-smelly-poisonous-molecule-sure-fire-extraterrestrial.html
1/3/2020 6:00 PMPhase 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
1/4/2020 8:00 AMScientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory are exceptional in many respects. Working in collaboration with the Imperial College London, for example, they have conducted research on a phenomenon in information processing systems called “exceptional points.” This phenomenon has found applications in microwave, optical and mechanical technologies.https://phys.org/news/2019-12-scientists-exceptional-surface.html

1/4/2020 12:00 PMWe live in Carl Sagan’s universe–awesomely vast, deeply humbling. It’s a universe that, as Sagan reminded us again and again, isn’t about us. We’re a granular element. 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 PMA 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. The breakthrough offers an alternative to previously held assumptions about how particles accumulate in lakes and oceans and could lead to applications in locating biological hotspots, cleaning up the environment and even in sorting and packing.https://phys.org/news/2019-12-fundamental-underwater.html
1/4/2020 4:00 PMThe Earth’s inner core is hot, under immense pressure and snow-capped, according to new research that could help scientists better understand forces that affect the entire planet. The snow is made of tiny particles of iron—much heavier than any snowflake on Earth’s surface—that fall from the molten outer core and pile on top of the inner core, creating piles up to 200 miles thick that cover the inner core.https://phys.org/news/2019-12-scientists-iron-earth-core.html
1/4/2020 6:00 PMA critically endangered toad belonging to one of the most threatened groups of amphibians in the world has been documented by scientists for the first time in 30 years.https://www.newsweek.com/spectacular-starry-night-harlequin-toad-lost-science-1476978
1/5/2020 8:00 AMEarth’s magnetic north pole, which has been wandering faster than expected in recent years, has now crossed the prime meridian.https://www.space.com/earth-magnetic-north-passes-prime-meridian.html

1/5/2020 12:00 PMFarmers could soon be growing tomatoes bunched like grapes in a storage unit, on the roof of a skyscraper, or even in space. That’s if a clutch of new gene-edited crops prove as fruitful as the first batch.https://phys.org/news/2019-12-tomato-ideal-urban-gardens-outer.html
1/5/2020 2:00 PMA European team of researchers including physicists from the University of Konstanz has found a way of transporting electrons at times below the femtosecond range by manipulating them with light. This could have major implications for the future of data processing and computing.https://phys.org/news/2019-12-electronics.html
1/5/2020 4:00 PMScientists from the University of Bristol, in collaboration with the Technical University of Denmark (DTU), have successfully developed chip-scale devices that are able to harness the applications of quantum physics by generating and manipulating single particles of light within programmable nanoscale circuits.https://phys.org/news/2019-12-chip-to-chip-quantum-teleportation-harnessing-silicon.html

1/6/2020 8:00 AMStarting in 536 A.D., the sky went dark for more than a year. In some parts of Europe and Asia, the sun only shone for about four hours a day, and “accounts say the sun gave no more light than the moon,” says Dallas Abbott, who studies paleoclimate and extraterrestrial impacts at Columbia University’s Lamont-Doherty Earth Observatory.https://phys.org/news/2019-12-undersea-volcanism-medieval-year-darkness.html

1/6/2020 12:00 PMSkywatchers from Saudi Arabia and Oman to India and Singapore were treated to a “ring of fire” solar eclipse Thursday, December 26th.https://phys.org/news/2019-12-eclipse-wows-asia.html
1/6/2020 2:00 PMPrinceton researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists’ control over light and boosting research into next-generation solar and optical devices.https://phys.org/news/2019-12-illuminate-absorb-emit.html
1/6/2020 4:00 PMIn this age of “big data,” artificial intelligence (AI) has become a valuable ally for scientists. Machine learning algorithms, for instance, are helping biologists make sense of the dizzying number of molecular signals that control how genes function. But as new algorithms are developed to analyze even more data, they also become more complex and more difficult to interpret. Quantitative biologists Justin B. Kinney and Ammar Tareen have a strategy to design advanced machine learning algorithms that are easier for biologists to understand.https://phys.org/news/2019-12-machine-gene.html
1/6/2020 6:00 PMRats have mastered the art of driving a tiny car, suggesting that their brains are more flexible than we thought. The finding could be used to understand how learning new skills relieves stress and how neurological and psychiatric conditions affect mental capabilities.https://www.newscientist.com/article/2220721-scientists-have-trained-rats-to-drive-tiny-cars-to-collect-food/
1/7/2020 8:00 AMParker Solar Probe launched in August 2018, destined to spend seven years looping ever closer to the sun in hopes of sorting out some of the hottest mysteries about our star. But to do so, the spacecraft needed a carefully choreographed trajectory, one that included seven flybys of Earth’s evil twin, Venus. And Venus scientists, who haven’t had a dedicated NASA spacecraft since the mid-1990s, were not about to let that opportunity fly past them.https://www.space.com/parker-solar-probe-venus-flyby-observations-december-2019.html

1/7/2020 12:00 PMThe star Betelgeuse comprises the shoulder of the constellation Orion, and its abrupt change in brightness hints that it may be on the brink of death. If this star is indeed at the end of its life, it will not go gently into that good night. Before Betelgeuse blips out for good, it will explode in a supernova—a violent stellar cataclysm that could outshine the moon and make it visible even in daylight.https://www.smithsonianmag.com/smart-news/giant-star-betelgeuse-dimming-sign-it-could-explode-180973861/

1/7/2020 4:00 PMFresh findings about the edge of Earth’s atmosphere are puzzling scientists affiliated with two missions that launched this year, and then some. This zone, at an altitude of roughly 50 to 400 miles (80 to 645 kilometers), is full of strange physical phenomena that scientists are only beginning to understand. In the ionosphere, charged particles released by the sun interact with gases at the top of Earth’s atmosphere in intriguing ways.https://www.space.com/ionosphere-science-roundup.html
1/7/2020 6:00 PMDr. Merritt Moore — a quantum physicist and professional ballerin — graduated with Magna Cum Laude Honors in Physics from Harvard and recently graduated with a PhD in Atomic and Laser Physics from the University of Oxford. At the same time, her professional ballet career has seen her dance with the Zurich Ballet, Boston Ballet, English National Ballet, and Norwegian National Ballet.https://medium.com/@daniellenewnham/interview-with-quantum-physicist-and-pro-ballerina-dr-merritt-moore-23862cbb4e64
1/8/2020 8:00 AMOnly four spacecraft ever launched are currently on their way out of the solar system – Pioneer 10 and 11, and Voyager 1 and 2 – and now we know which one will pass by another star system first. (hint – it’s Pioneer 10, and it’ll pass by star system HIP 117795 in about 90,000 years). Altogether, the four probes will pass by approximately 60 star systems in the next one million years, and about 100,000,000,000,000,000,000 years before they’ve all collided with or are captured by a star system.https://phys.org/news/2019-12-spacecraft-star.html

1/8/2020 2:00 PMThe tail of a feathered dinosaur has been found perfectly preserved in amber from Myanmar. The one-of-a-kind discovery helps put flesh on the bones of these extinct creatures, opening a new window on the biology of a group that dominated Earth for more than 160 million years.https://www.bbc.com/news/science-environment-38224564
1/8/2020 4:00 PMIf the thought of sipping a beer is gag-inducing, you’re not alone. But even if you’re in good company, it begs the question: Why do some people hate the taste of beer? The answer comes down to genetics, which influences how our brains process bitter-tasting and cold beverages.https://www.livescience.com/63039-why-hate-bitter-beer-taste.html
1/8/2020 6:00 PMMany human languages have words for emotions such as “anger” and “fear,” yet it is not clear whether these emotions have similar meanings across languages, or why their meanings might vary.https://science.sciencemag.org/content/366/6472/1517
1/9/2020 8:00 AMNew research suggests forces pulling on Earth’s surface as the planet spins may trigger earthquakes and eruptions at volcanoes.https://phys.org/news/2019-12-earth-earthquakes-volcanic-eruptions-mount.html

1/9/2020 12:00 PMIn a paper published in Proceedings of the National Academy of Sciences (PNAS) Saint Louis University researchers report new information about conditions that can cause Earth’s tectonic plates to sink.http://www.geologypage.com/2016/11/geologists-discover-tectonic-plate-sank.html
1/9/2020 2:00 PMLupus can be a stubborn disease to treat. Although many struck by the autoimmune condition live relatively normal lives, some suffer from kidney failure, blood clots, and other complications that can be deadly. Now, scientists have found that a novel treatment that wipes out the immune system’s B cells cures mice of the condition. Though the work is preliminary, it has excited researchers because it uses a therapy already approved for people with blood cancer.https://www.sciencemag.org/news/2019/03/genetically-engineered-immune-cells-wipe-out-lupus-mice
1/9/2020 4:00 PMThe 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
1/9/2020 6:00 PMUsing data from an especially bright population of stars, astronomers have reconstructed the Milky Way’s peaks and valleys like never before.https://www.pbs.org/wgbh/nova/article/milky-way-3d-map-cepheids/
1/10/2020 8:00 AMThe small hopping insect Issus coleoptratus uses toothed gears to precisely synchronize the kicks of its hind legs as it jumps forward.https://www.smithsonianmag.com/science-nature/this-insect-has-the-only-mechanical-gears-ever-found-in-nature-6480908/

1/10/2020 12:00 PMThe theoretical notion of a ‘quantum heat engine’ has been around for several decades. It was first introduced around sixty years ago by Scovil and Schulz-DuBois, two physicists at Bell Labs who drew an analogy between three-level masers and thermal machines.https://phys.org/news/2019-12-experimental-quantum.html
1/10/2020 2:00 PMScientists from Skoltech and Heriot-Watt University proposed extracting methane by injecting flue gas into permafrost hydrate reservoirs. Since the flue gas contains carbon dioxide, the new technology will also contributes to reduction of this green house gas in the Arctic atmosphere.https://phys.org/news/2019-12-gas-efficiently-methane-permafrost.html

1/10/2020 6:00 PMAs students, Jussi Lindgren and Jukka Liukkonen had found one element of their quantum mechanics lectures unsatisfying. “When we were taught physics, there were some fundamental elements you were told were true, and you had to accept they were true without it being shown why,” said Jussi Lindgren, “and I didn’t really like this”.https://phys.org/news/2019-12-rewriting-quantum-mechanics.html
1/11/2020 8:00 AMUsing the National Science Foundation’s Karl G. Jansky Very Large Array radio telescope, a team of astronomers has captured for the first time an image of large-scale, coherent, magnetic fields in the halo of a faraway spiral galaxy, confirming theoretical modeling of how galaxies generate magnetic fields and potentially increasing knowledge of how galaxies form and evolve.https://phys.org/news/2019-12-giant-magnetic-ropes-whale-galaxy.html
1/11/2020 10:00 AMAuroras paint the sky around the poles when the sun is particularly active, flinging highly charged particles at Earth’s atmosphere. Scientists once thought that the gorgeous events were mirror images, but to their surprise, displays at the north (the aurora borealis) and south (the aurora australis) don’t precisely match.https://www.space.com/43130-northern-lights-auroras-different-in-south.html
1/11/2020 12:00 PMA group of researchers from the Potsdam Institute for Climate Impact Research, Beijing Normal University and Justus-Liebig-Universität Giessen has found a way to predict El Niño events up to a year before they occur. In their paper published in the Proceedings of the National Academy of Sciences, the group describes their complexity-based approach to better predicting the seemingly random weather events.https://phys.org/news/2019-12-el-nio-event-year.html
1/11/2020 2:00 PMWithout a doubt, Tyrannosaurus rex is the most famous dinosaur in the world. The 40-foot-long predator with bone crushing teeth inside a five-foot long head are the stuff of legend. Now, a look within the bones of two mid-sized, immature T. rex allow scientists to learn about the tyrant king’s terrible teens as well.https://phys.org/news/2020-01-teen-age-trex.html
1/11/2020 4:00 PMWhat freshwater turtle has no shell, lives in southeast Asia, and can grow as much as 6 feet (2 meters) long? Meet the Asian giant softshell turtle (Pelochelys cantorii). Unlike many of its turtle relatives—it has no exterior shell, just a layer of thick rubbery skin covering wide-spanning, fused ribs that protect its internal organs. Its frog-like face adds to its unusual appearance. This reptile can be found in freshwater habitats where it burrows beneath the sand with only its snout poking out. Unfortunately, the species is threatened by loss of its riverine and coastal habitats, as well as by being hunted for its meat and eggs.https://tumblr.amnh.org/post/189913727679/what-freshwater-turtle-has-no-shell-lives-in
1/11/2020 6:00 PMA team of astronomers at the National Centre for Radio Astrophysics (NCRA) in Pune, India have discovered a mysterious ring of hydrogen gas around a distant galaxy, using the Giant Metrewave Radio Telescope (GMRT). The ring is much bigger than the galaxy it surrounds and has a diameter of about 380,000 light-years (about 4 times that of our Milky Way).https://phys.org/news/2020-01-gmrt-gigantic-hydrogen-gas-distant.html
1/12/2020 8:00 AMOn frigid days, water vapor in the air can transform directly into solid ice, depositing a thin layer on surfaces such as a windowpane or car windshield. Though commonplace, this process is one that has kept physicists and chemists busy figuring out the details for decades.https://phys.org/news/2020-01-thin-ice.html
1/12/2020 10:00 AMNo one really knows what happens inside an atom. But two competing groups of scientists think they’ve figured it out. And both are racing to prove that their own vision is correct.https://www.space.com/mystery-of-proton-neutron-behavior-in-nucleus.html
1/12/2020 12:00 PMOn a hillside above Stanford University, the SLAC National Accelerator Laboratory operates a scientific instrument nearly 2 miles long. In this giant accelerator, a stream of electrons flows through a vacuum pipe, as bursts of microwave radiation nudge the particles ever-faster forward until their velocity approaches the speed of light, creating a powerful beam that scientists from around the world use to probe the atomic and molecular structures of inorganic and biological materials.https://phys.org/news/2020-01-particle-chip.html
1/12/2020 2:00 PM“The inhabitants of the Border Cave in the Lebombo Mountains on the Kwazulu-Natal/eSwatini border were cooking starchy plants 170 thousand years ago,” says Professor Lyn Wadley, a scientist from the Wits Evolutionary Studies Institute at the University of the Witwatersrand, South Africa (Wits ESI). “This discovery is much older than earlier reports for cooking similar plants and it provides a fascinating insight into the behavioural practices of early modern humans in southern Africa. It also implies that they shared food and used wooden sticks to extract plants from the ground.”https://phys.org/news/2020-01-early-modern-humans-cooked-starchy.html
1/12/2020 4:00 PMIt’s hard to imagine Ohio was once what some would consider a paradise in a vast ocean with tropical weather, considering over 500 million years later we’re landlocked and the weather is as unpredictable as it’s ever been. However, that’s the reality of Ohio’s history — south of the equator, immersed in warm sea water, Ohio supported a variety of marine life. The proof is in the thousands of fossils that can be found in Ohio today.https://www.farmanddairy.com/top-stories/how-to-hunt-for-fossils-in-ohio/592400.html
1/12/2020 6:00 PMFor the first time, researchers have performed a version of the famous double-slit experiment with antimatter particles.https://www.sciencenews.org/article/antimatter-quantum-theory-particle-wave-double-slit-experiment
1/13/2020 8:00 AMA strange, small cone-shaped fossil baffled scientists for a very long time. Now that it has found its family, you’ll never guess its closest living relative.http://www.eartharchives.org/articles/conularia-were-the-cone-shaped-weirdos-of-the-paleozoic/
1/13/2020 10:00 AMAt a recent group meeting, my postdoc raised a question: “Should we make our theoretical model more complex so that our explanation of the data will not appear too trivial?” I was surprised by this suggestion and felt obligated to explain why. “Simplicity is a virtue,” I said, “not a deficiency. Excessive mathematical gymnastics is used to show off in branches of theoretical physics that have scarce experimental data. But as physicists, we should seek the simplest explanation for our data. This is the lifeblood of physics and the appropriate measure of success.”https://blogs.scientificamerican.com/observations/the-simple-truth-about-physics/
1/13/2020 12:00 PMA study led by Kevin Reed, Ph.D., Assistant Professor in the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University, and published in Science Advances, found that Hurricane Florence produced more extreme rainfall and was spatially larger due to human-induced climate change.https://phys.org/news/2020-01-climate-impacted-hurricane-florence-precipitation.html
1/13/2020 2:00 PMResearchers at Columbia University and University of California, San Diego, have introduced a novel “multi-messenger” approach to quantum physics that signifies a technological leap in how scientists can explore quantum materials.https://phys.org/news/2020-01-quantum-breakthrough-technique-astronomy-nano-scale.html
1/13/2020 4:00 PMIt’s official: India will try again to land on the moon. The Chandrayaan-3 mission, which will consist of a lunar rover and a stationary lander, has been approved by the Indian government, K. Sivan, the chairman of the Indian Space Research Organisation (ISRO), announced during a news conference Wednesday, January 1, 2020.https://www.space.com/india-confirms-moon-landing-mission-chandrayaan-3.html
1/13/2020 6:00 PMThe title of this article is a bit misleading. This dish in South Africa is just 50 feet wide – nowhere near a square kilometer – but it’s the first of a planned 3,000 such dishes, spread through Botswana, Ghana, Madagascar, Mauritius, Mozambique, Namibia, and Zambia. Collectively, with another station in Australia, they will be known as the Square Kilometer Array (SKA).https://www.wired.com/story/square-kilometre-array-largest-scientific-structure-ever-africa/
1/14/2020 8:00 AMThe global low-carbon revolution could be at risk unless new international agreements and governance mechanisms are put in place to ensure a sustainable supply of rare minerals and metals, a new academic study has warned.https://phys.org/news/2020-01-sustainable-minerals-metals-key-low-carbon.html
1/14/2020 10:00 AMTwo teams of astronomers independently have gotten the first glimpses of the surface of a pulsar, a rapidly spinning neutron star. Newly created maps of that surface reveal a smattering of bright blemishes in the star’s southern hemisphere, hinting at the presence of complex magnetic fields.https://www.sciencenews.org/article/first-glimpses-pulsar-surface-hint-complex-magnetism
1/14/2020 12:00 PMIn sailing, rock climbing, construction, and any activity requiring the securing of ropes, certain knots are known to be stronger than others. Any seasoned sailor knows, for instance, that one type of knot will secure a sheet to a headsail, while another is better for hitching a boat to a piling.https://phys.org/news/2020-01-mathematical-stability.html
1/14/2020 2:00 PMSerena Auñón-Chancellor, M.D., M.P.H., Clinical Associate Professor of Medicine at LSU Health New Orleans School of Medicine’s branch campus in Baton Rouge, is the lead author of a paper describing a previously unrecognized risk of spaceflight discovered during a study of astronauts involved in long-duration missions. The paper details a case of stagnant blood flow resulting in a clot in the internal jugular vein of an astronaut stationed on the International Space Station.https://phys.org/news/2020-01-occurrence-treatment-spaceflight-medical-miles.html
1/14/2020 4:00 PMIf a meteorite streaking through Earth’s atmosphere is too thin, it’ll tumble about. Too wide and it will flutter wildly. But if it’s taken on just the right cone shape, it’ll plummet straight to the ground.https://www.pbs.org/wgbh/nova/article/cone-meteorites/

2/3/2020 4:00 PMHumanity’s most far-flung spacecraft, NASA’s 41-year-old Voyager 1, has poked a hole in a long-shot theory of dark matter. Some theorists have argued that the mysterious, unseen stuff, which makes up 85% of the universe’s matter, could consist of countless black holes lingering from the big bang. But Voyager 1, which launched in 1977 and slipped out of the solar system 6 years ago, sees no signs of such hordes, a pair of theoretical physicists reports. The data don’t kill the idea that dark matter is black holes entirely, however, as Voyager 1 can detect only tiny black holes.https://www.sciencemag.org/news/2019/01/aging-voyager-1-spacecraft-undermines-idea-dark-matter-tiny-black-holes

2/11/2020 6:00 PMOne 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

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

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 PMThe 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

4/8/2020 12:00 PMhe universe really likes its information. It doesn’t like to create new information, and it doesn’t like to destroy any of its existing information. In fact, “like” is far too weak of a word. As far as we can tell (and we’ve worked really, really hard to check), information is neither created nor destroyed: information throughout the universe simply persists.https://www.space.com/black-hole-information-paradox-mystery.html

For years, researchers have been serially demonstrating that one particular new cell type can transfer its mitos to yet another particular cell type to achieve some specific metabolic goal essential to survival of the meta-host organism. But what happens when the mitochondria come from the outside world, from other members of your own species, or from a different species altogether? In addressing this very real situation, we first must look at the particulars of how and why mitos are transmitted across cell boundaries in the first place.https://phys.org/news/2020-03-free-range-mitochondria.html

4/9/2020 6:00 PMWhen 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.

5/12/2020 12:00 PMBlood 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

We’ve got a lot of air, more liquid water than we know what to do with, a nice strong planetary magnetic field that protects us cosmic radiation, and nice strong gravity that keeps our muscles strong and our bones thick.https://www.space.com/venus-runaway-greenhouse-effect-earth-next.html
5/17/2020 10:00 AMPublic 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 PMScientists 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 PMThere 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 PMThere 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/

5/27/2020 2:00 PMIf 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 10:00 AMCatmint, 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 PMAs 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 AMAccording 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 hologramshttps://phys.org/news/2020-06-black-holes-hologram.html

6/15/2020 6:00 PMOf 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/

6/16/2020 12:00 PMA prehistoric “Icebird” has been found in Siberian permafrost in remarkably good shape. 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. That enables scientists and researchers to discover a great deal about these species, as they arrive in labs almost identical to the way they looked thousands of years ago.https://www.thevintagenews.com/2020/02/25/icebird/

6/17/2020 2:00 PMThe 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
6/17/2020 4:00 PMWhen the Sun is well overhead, the floor of the Mare Tranquillitatis pit is illuminated. 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. Compare this depth to the width, which ranges from 100 to 115 meters across the sharp precipice.http://lroc.sese.asu.edu/posts/230

6/25/2020 12:00 PMThe brain continues to surprise us with its magnificent complexity. Groundbreaking research that combines neuroscience with math tells us that our brain creates neural structures with up to 11 dimensions when it processes information. By “dimensions,” they mean abstract mathematical spaces, not other physical realms. Still, the researchers “found a world that we had never imagined,” said Henry Markram, director of the Blue Brain Project, which made the discovery.https://bigthink.com/paul-ratner/our-brains-think-in-11-dimensions-discover-scientists

6/27/2020 10:00 AMEgyptian 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.

7/9/2020 12:00 PMAstronomers around the world may have lost access to their telescopes during the coronavirus pandemic, sheltering in place along with the rest of us, but that hasn’t kept them from advancing their field. Two astronomers used the shutdown to comb through existing datasets to hunt for a rare type of quasar and wound up rediscovering a so-called “Einstein ring” first observed back in 1987. They became the first to officially measure its distance from Earth, as reported in a recent paper.https://arstechnica.com/science/2020/06/astronomers-have-finally-measured-the-distance-of-first-observed-einstein-ring/

7/11/2020 10:00 AMWater security is becoming an urgent global challenge. Hundreds of millions of people already live in water-scarce regions, and the UN projects that by 2030 about half the world’s population will be living in highly water-stressed areas. This will be a crisis even for developed countries like the U.S., where water managers in 40 states expect freshwater shortages within the next 10 years. As the global population and GDP grow, so will the demand for freshwater. And, with the continuing rise of global temperatures, water shortages will only get worse.https://phys.org/news/2020-06-unorthodox-desalination-method-global.html

7/15/2020 4:00 PMPhysicists 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

7/26/2020 4:00 PMThe 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.

7/29/2020 6:00 PMSunspots 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 AMYou’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

8/1/2020 6:00 PMLaura Lewis and her team of researchers have been putting in late nights in their Boston University lab. 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/
8/2/2020 8:00 AMOver two dozen misidentified supermassive black holes have finally been revealed in a new, sky-scanning study. A team of researchers led by Erini Lambrides of Johns Hopkins University (JHU) in Baltimore, Maryland has spotted 28 supermassive black holes that have been masquerading as other cosmic objects using a host of telescopes including NASA’s Chandra X-ray Observatory, Hubble Space Telescope and Spitzer Space Telescope. The team observed these black holes which lie 5 billion light-years or more away within the Chandra Deep Field-South (CDF-S), the deepest X-ray image ever taken.https://www.space.com/misidentified-supermassive-black-holes-discovered.html

8/2/2020 4:00 PMIn the early morning hours of July 20 on Tanegashima, a small island just off the southern coast of Kyushu, Japan, a 174-foot rocket roared to life and lifted a spacecraft on the first leg of a 306-million-mile journey to Mars. The spacecraft itself, however, is not Japanese. Called al-Amal, or “Hope,” it was designed and managed by the Mohammed Bin Rashid Space Centre (MBRSC) in the United Arab Emirates. Safely separated now from the Japanese rocket, the probe will fire its own thrusters to leave Earth orbit for Mars in about 28 days, arriving in February 2021 to complete the first interplanetary voyage initiated by an Arab country.https://www.nationalgeographic.com/science/2020/07/uae-mars-mission-hope-aims-inspire-new-generation-space-scientists/

8/3/2020 12:00 PMThe Sun is an ordinary star. It bathes the solar system with light and heat, making life possible on Earth. It’s as regular as clockwork, and it sets our daily life cycles in conjunction with Earth’s spin. Little wonder ancient peoples revered the Sun as a god. Yet the Sun will not always be steady and reliable. Billions of years from now, the Sun’s finale will turn Earth — and the entire inner solar system — into a very nasty place.https://astronomy.com/magazine/greatest-mysteries/2019/07/42-what-will-happen-to-the-sun

8/4/2020 4:00 PMThe 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

8/9/2020 6:00 PMThere 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.

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

8/17/2020 10:00 AMBack to the Future, The Terminator, The Time Machine, all of these stories share a central theme where traveling through time is a dangerous proposition that could destroy the very fabric of our reality. 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 AMIn 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 PMA 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

8/27/2020 8:00 AMA 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. Their findings are important for improving predictions of future sea ice change.https://phys.org/news/2020-08-evidence-loss-arctic-sea-ice.html
8/27/2020 10:00 AMArctic sea ice is melting more quickly than once assumed. Today’s climate models have yet to incorporate the steep rise in temperatures that have occurred over the past 40 years. This, according to a new study by researchers at the University of Copenhagen and other institutions.https://phys.org/news/2020-08-underestimated-pace-arctic.html
8/27/2020 12:00 PMPlants are factories that manufacture yield from light and carbon dioxide—but parts of this complex process, called photosynthesis, are hindered by a lack of raw materials and machinery. To optimize production, scientists from the University of Essex have resolved two major photosynthetic bottlenecks to boost plant productivity by 27 percent in real-world field conditions, according to a new study published in Nature Plants. This is the third breakthrough for the research project Realizing Increased Photosynthetic Efficiency (RIPE); however, this photosynthetic hack has also been shown to conserve water.https://phys.org/news/2020-08-breakthrough-photosynthetic-hacks-boost-yield.html

8/27/2020 6:00 PMPhysicists 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

When Hamilton College Associate Professor of Biology Andrea Townsend began studying the social behavior of American crows, her work was complicated by West Nile virus, an emerging disease with devastating effects on crow populations. Her research pivoted to investigating the effects of disease on crow social behavior. “It made me wonder how social animals should, in general, respond to novel diseases,” Townsend said. “Do other animals ‘socially distance’ during disease outbreaks, like humans during the COVID-19 pandemic?”https://phys.org/news/2020-08-emerging-infectious-disease-social-distancing.html
8/30/2020 12:00 PMThe 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

9/5/2020 8:00 AMIs 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 PMA 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

9/13/2020 12:00 PM“Is it a wave or is it a particle?” Never has such a simple question had such a complicated answer as in the quantum realm. The answer, perhaps frighteningly, depends on how you ask the question. Pass a beam of light through two slits, and it acts like a wave. Fire that same beam of light into a conducting plate of metal, and it acts like a particle. 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/

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. But for the vast majority of our history, humans didn’t understand the number zero. It’s not innate in us. We had to invent it. And we have to keep teaching it to the next generation.https://www.vox.com/science-and-health/2018/7/5/17500782/zero-number-math-explained

Scientists found that the ancestral dog population still stealthily wanders in the Highlands of New Guinea. This finding opens new doors for protecting a remarkable creature that can teach biologists about human vocal learning. The New Guinea singing dog can also be utilized as a valuable and unique animal model for studying how human vocal disorders arise and finding potential treatment opportunities. The study was performed by researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, Cenderawasih University in Indonesia, and other academic centers.https://phys.org/news/2020-08-discovery-ancient-dog-species-human.html

The research team, which includes physicists from the University of Maryland, detected two black holes merging, but one of the black holes was 1 1/2 times more massive than any ever observed in a black hole collision. The researchers believe the heavier black hole in the pair may be the result of a previous merger between two black holes.This type of hierarchical combining of black holes has been hypothesized in the past but the observed event, labeled GW190521, would be the first evidence for such activity.https://phys.org/news/2020-09-heaviest-black-hole-merger-gravitational.html
9/22/2020 10:00 AMHas the universe been around forever? If so, perhaps it’s been bouncing back and forth in a never-ending cycle of big bangs in which all matter bubbles out of a singularity, followed by big crunches, in which everything gets swallowed up again to form that dense point from which the universe is born again.

9/25/2020 6:00 PMIn 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 AMA 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 PMAround 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

9/27/2020 2:00 PMUntil 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/

10/4/2020 6:00 PMThe 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

10/5/2020 12:00 PMBringing the power of the sun to Earth requires sound theory, good engineering, and a little finesse. The process entails trapping charged, ultra-hot gas known as plasma so its particles can fuse and release enormous amounts of energy. The most widely used facilities for this process are doughnut-shaped tokamaks that hold plasma in place with strong magnets that are precisely shaped and positioned. But errors in the shaping or placement of these magnets can lead to poor confinement and loss of plasma, shutting down fusion reactions.https://phys.org/news/2020-09-scientists-technique-advance-quest-fusion.html

10/10/2020 2:00 PMUnlike 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

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

10/15/2020 8:00 AMThe vast majority of planets near foreign stars are discovered by astronomers with the help of sophisticated methods. The exoplanet does not appear in the image, but reveals itself indirectly in the spectrum. A team of scientists from the Max Planck Institutes for Astronomy and Extraterrestrial Physics has now succeeded in obtaining the first direct confirmation of a previously discovered exoplanet using the method of radial velocity measurement. Using the the GRAVITY instrument at the VLT telescopes in Chile, the astronomers observed the faint glint of the planet Beta Pictoris c, some 63 light-years away from Earth, next to the bright rays of its mother star. The researchers can now derive both the brightness and the dynamic mass of an exoplanet from these observations and thus better narrow down the formation models of these objects.https://phys.org/news/2020-10-astronomers-reveal-image-beta-pictoris.html
10/15/2020 10:00 AMRUDN mathematicians analyzed the properties of gravitational waves in a generalized affine-metrical space (an algebraic construction operating on the notions of a vector and a point) similarly to the properties of electromagnetic waves in Minkowski space-time. They report the possibility of transmitting information with the help of nonmetricity waves and transferring it spatially without distortions. The discovery could lead to a new means of data transfer in space, e.g., between space stations.https://phys.org/news/2018-10-mathematicians-possibility-gravitational.html

10/15/2020 4:00 PMWe don’t usually post pre-prints, but we couldn’t resist this one. A group of physicists from Georgia Tech went to Zoo Atlanta to watch animals urinating. To their surprise, they discovered that regardless of size, most mammals urinate for about the same amount of time (21 seconds), despite large differences in bladder volume, a phenomenon they term the “Law of Urination”. They explain this law using physics, and illustrate their explanation with an amazing video (below) that is absolutely a must-see.https://www.discovermagazine.com/planet-earth/regardless-of-bladder-size-all-mammals-pee-for-approximately-21-seconds-with-video-goodness
10/15/2020 6:00 PMQuantum 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

10/16/2020 2:00 PMSomething is raining gold across the universe – but no one knows what it is. 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 PMThe 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 4:00 PMOnly 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.

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 PMAt 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 2:00 PMThere 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 PMOnce 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 PMThe 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

10/23/2020 10:00 AMAn 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

10/27/2020 10:00 AMReinfection, 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
10/27/2020 12:00 PMOnce 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

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. Still, the scientists have now separated the effects of the ice loss from other effects and quantified it.https://phys.org/news/2020-10-ice-loss-due-vicious-circle.html

11/10/2020 4:00 PMThe 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

11/11/2020 8:00 AMIn 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 AMThe 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 4:00 PMAt 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
