1/1/2021 2:00 PMPeople around the world are currently isolating themselves or in a formal quarantine to prevent the spread of the SARS-CoV-2 coronavirus. But for decades, astronauts have been quarantined to ensure that they were virus-free and ready to fly (or, in the case of Apollo, to make sure they didn’t bring home any “moon bugs.”) This quarantine period “ensures that they aren’t sick or incubating an illness when they get to the space station,” NASA spokesperson Brandi Dean told Space.com. So what is quarantine really like for an astronaut?https://www.space.com/what-is-quarantine-like-for-astronauts-coronavirus.html

1/2/2021 8:00 AMHydrogen is a sustainable source of clean energy that avoids toxic emissions and can add value to multiple sectors in the economy including transportation, power generation, metals manufacturing, among others. Technologies for storing and transporting hydrogen bridge the gap between sustainable energy production and fuel use, and therefore are an essential component of a viable hydrogen economy. But traditional means of storage and transportation are expensive and susceptible to contamination. As a result, researchers are searching for alternative techniques that are reliable, low-cost and simple. More-efficient hydrogen delivery systems would benefit many applications such as stationary power, portable power, and mobile vehicle industries.https://phys.org/news/2020-12-nanomaterial-hydrogen-liquid-energy-carrier.html

1/25/2021 10:00 AMA new Northwestern University-led study is unfolding the mystery of how RNA molecules fold themselves to fit inside cells and perform specific functions. The findings could potentially break down a barrier to understanding and developing treatments for RNA-related diseases, including spinal muscular atrophy and perhaps even the novel coronavirus.https://phys.org/news/2021-01-videos-rna.html
1/25/2021 12:00 PMA team of biophysicists from the University of Massachusetts Amherst and Penn State College of Medicine set out to tackle the long-standing question about the nature of force generation by myosin, the molecular motor responsible for muscle contraction and many other cellular processes. The key question they addressed—one of the most controversial topics in the field—was: how does myosin convert chemical energy, in the form of ATP, into mechanical work?https://phys.org/news/2021-01-ground-molecular-motor.html
1/25/2021 2:00 PMScientists studying the body’s natural defenses against bacterial infection have identified a nutrient—taurine—that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding, published in the journal Cell by scientists from five institutes of the National Institutes of Health, could aid efforts seeking alternatives to antibiotics.https://phys.org/news/2021-01-scientists-nutrient-bacterial-infection.html
1/25/2021 4:00 PMWhen darkness comes, electric eels emerge from South American river bottoms to attack their prey with up to 860 volts of electricity—enough to kill a person. Now, scientists have revealed the snakelike fish don’t always go it alone: They hunt in packs, similar to wolves, orcas, and some species of tuna. The finding, a first among electric fishes, may open the way for new studies to investigate when social predation evolved among fishes.https://www.sciencemag.org/news/2021/01/shocking-discovery-electric-eels-hunt-packs-amazon-rivers
1/25/2021 6:00 PMThe Milky Way houses 8,292 recently discovered stellar streams—all named Theia. But Theia 456 is special. A stellar stream is a rare linear pattern—rather than a cluster—of stars. After combining multiple datasets captured by the Gaia space telescope, a team of astrophysicists found that all of Theia 456’s 468 stars were born at the same time and are traveling in the same direction across the sky.https://phys.org/news/2021-01-theia-stars-born.html

1/26/2021 10:00 AMPut a particle in a box. According to classical physics (and common sense), that particle should stay in that box forever. But under quantum mechanics, that particle can simply be outside the box the next time you look. In classical thinking, you can measure the momentum and position of something to an arbitrary degree of precision. Not so in the quantum world — the more you know about one, the less you know about the other. Is something a wave or a particle? According to the classical viewpoint, you can pick one and only one. But ask your friendly neighborhood quantum mechanic, and they’ll tell you something can be both.https://www.space.com/do-we-live-in-quantum-world.html
1/26/2021 12:00 PMScientists have figured out a way to create and cancel magnetic fields from afar. The method involves running electric current through a special arrangement of wires to create a magnetic field that looks as if it came from another source. This illusion has real applications: Imagine a cancer drug that could be delivered directly to a tumor deep in the body by capsules made of magnetic nanoparticles. It’s not possible to stick a magnet in the tumor to guide the nanoparticles on their journey, but if you could create a magnetic field from outside the body that centered right on that tumor, you could deliver the drug without an invasive procedure.https://www.space.com/magnetic-fields-created-from-afar

1/27/2021 12:00 PMAn “Old Faithful”-like event in space may shed light on the nature of stars near supermassive black holes embedded in galaxies. Researchers saw repeated outbursts — every 114 days, on average — in a galaxy some 570 million light-years away from Earth. (For perspective, the nearest star system to Earth is roughly 4 light-years away.) The event, known as ASASSN-14ko, is flaring vehemently and in several wavelengths of light.https://www.space.com/old-faithful-galaxy-outbursts-114-days

1/27/2021 4:00 PMEven if you weren’t a physics major, you’ve probably heard something about the Higgs boson. There was the title of a 1993 book by Nobel laureate Leon Lederman that dubbed the Higgs “The God Particle.” There was the search for the Higgs particle that launched after 2009’s first collisions inside the Large Hadron Collider in Europe. There was the 2013 announcement that Peter Higgs and Francois Englert won the Nobel Prize in Physics for independently theorizing in 1964 that a fundamental particle—the Higgs—is the source of mass in subatomic particles, making the universe as we know it possible. Now Jigang Wang, a professor of physics and astronomy at Iowa State and a senior scientist at the U.S. Department of Energy’s Ames Laboratory, and a team of researchers have discovered a form of the famous particle within a superconductor, a material capable of conducting electricity without resistance, generally at very cold temperatures.https://phys.org/news/2021-01-light-controlled-higgs-modes-superconductors-potential.html

1/30/2021 10:00 AMIn June 1991, Mount Pinatubo, a volcanic peak on the Philippine Island of Luzon, literally blew its top. It was the second-most powerful volcanic eruption of the 20th century, ten times stronger than Mount Saint Helens, and its effects were devastating. Lava and ash spewed into the surrounding environment in the Zambales Mountains, pooling in layers up to 600 feet thick in the valleys. Following the eruption, powerful typhoons and monsoon rains triggered landslides and ash flows that continued for many months. Eight hundred people lost their lives, and the lush forests that covered the mountain prior to the eruption were destroyed or severely damaged. In recent years, scientists returned to the region to survey the surviving mammal populations, and in a new paper in the Philippine Journal of Science, the team announced the rediscovery of a species of mouse that had long been feared to be extinct.https://phys.org/news/2021-01-rediscovery-extinct-pinatubo-volcano-mouse.html
1/30/2021 12:00 PMMars was a very different place as a young planet. Liquid water dotted the Red Planet’s landscape with lakes and rivers.

2/13/2021 6:00 PMThe Arctic Ocean was covered by up to 900-meter-thick shelf ice and was filled entirely with freshwater at least twice in the last 150,000 years. This surprising finding, reported in the latest issue of the journal Nature, is the result of long-term research by scientists from the Alfred Wegener Institute and the MARUM.

2/19/2021 8:00 AMThe human cellular kinome contains over 500 kinases, accounting for almost 2% of all our genes. It is currently impossible to gauge the phosphorylation status, or even phosphorylation potential, of the entire proteome of any cell. Mitochondria, on the other hand, use just 25 kinases. Moreover, their entire proteome contains only 1,136 proteins, at least according to the latest version of the Mitocarta Database.https://phys.org/news/2021-02-characterization-full-mitochondrial-kinome.html
2/19/2021 10:00 AMWater doesn’t currently exist on Mars’ surface, but it used to. We know this from dramatic dry canyons and river channels seen from orbit, as well as minerals on the surface that only form in liquid water. Around 3 billion years ago, something happened to Mars’ atmosphere, and most of the liquid water evaporated. But some of it may still be underground, safely shielded from harmful solar radiation that bombards the planet’s surface. Could those ancient pockets of water contain life?https://www.planetary.org/space-missions/tianwen-1

These findings revise the population history of no less than seven present-day African countries (Cameroon, Central African Republic, Democratic Republic of the Congo, Republic of the Congo, Gabon, Equatorial Guinea, and Angola) and challenges the commonly held belief that the settlement of Central Africa by Bantu-speaking communities was a continuous process from about 4000 years ago until the start of the transatlantic slave trade.https://phys.org/news/2021-02-epidemic-possibly-population-collapse-central.html
2/23/2021 6:00 PMPlanets, stars, and black holes all grow by consuming material from a spinning disk. While these disks may differ in size, they’re all mostly dependent on the mighty force of gravity, which keeps them spinning around the central mass. Gravity lets small clumps grow into bigger clumps. But it’s not enough to pull the whole disk into the middle in one giant clump, because angular momentum is pulling those clumps away from the center as they spin.https://astronomy.com/news/2019/02/scientists-finally-confirm-a-big-theory-about-solar-system-formation

3/4/2021 2:00 PMTracing back a ghostly particle to a shredded star, scientists have uncovered a gigantic cosmic particle accelerator. The subatomic particle, called a neutrino, was hurled towards Earth after the doomed star came too close to the supermassive black hole at the center of its home galaxy and was ripped apart by the black hole’s colossal gravity. It is the first particle that can be traced back to such a ‘tidal disruption event’ (TDE) and provides evidence that these little understood cosmic catastrophes can be powerful natural particle accelerators.https://phys.org/news/2021-02-ghost-particle-shredded-star-reveals.html

3/16/2021 6:00 PMThe cell membranes of all organisms contain ion channels that permit ions to pass into or out of the cell, and these channels play extremely important roles in fundamental physiological processes such as heartbeats and the rapid conduction of signals along neurons. An important property of these ion channels is their selective conductivity—they selectively permit the passage of particular ions. For example, potassium channels more readily permit the passage of potassium ions than the passage of sodium ions, despite the fact that potassium ions are larger.https://phys.org/news/2021-03-mechanism-cellular-ion-channels.html
3/17/2021 8:00 AMAbout 17 years ago, J.

3/24/2021 4:00 PMWhen it comes to microelectronics, there is one chemical element like no other: silicon, the workhorse of the transistor technology that drives our information society. The countless electronic devices we use in everyday life are a testament to how today very high volumes of silicon-based components can be produced at very low cost. It seems natural, then, to use silicon also in other areas where the properties of semiconductors—as silicon is one—are exploited technologically, and to explore ways to integrate different functionalities. Of particular interest in this context are diode lasers, such as those employed in barcode scanners or laser pointers, which are typically based on gallium arsenide (GaAs). Unfortunately though, the physical processes that create light in GaAs do not work so well in silicon. It therefore remains an outstanding, and long-standing, goal to find an alternative route to realizing a ‘laser on silicon.’https://phys.org/news/2021-03-key-long-sought-goal-silicon-based-laser.html

3/26/2021 2:00 PMOrbiting a red dwarf star 41 light-years away is an Earth-sized, rocky exoplanet called GJ 1132 b. In some ways, GJ 1132 b has intriguing parallels to Earth, but in other ways it is very different. One of the differences is that its smoggy, hazy atmosphere contains a toxic mix of hydrogen, methane and hydrogen cyanide. Scientists using NASA’s Hubble Space Telescope have found evidence this is not the planet’s original atmosphere, and that the first one was blasted away by blistering radiation from GJ 1132 b’s nearby parent star. The so-called “secondary atmosphere” is thought to be formed as molten lava beneath the planet’s surface continually oozes up through volcanic fissures. Gases seeping through these cracks seem to be constantly replenishing the atmosphere, which would otherwise also be stripped away by the star. This is the first time a secondary atmosphere has been detected on a world outside our solar system.https://phys.org/news/2021-03-earth-sized-exoplanet-lost-atmosphere-gained.html

3/28/2021 8:00 AMProteins are the key component in all modern forms of life. Hemoglobin, for example, transports the oxygen in our blood; photosynthesis proteins in the leaves of plants convert sunlight into energy; and fungal enzymes help us to brew beer and bake bread. Researchers have long been examining the question of how proteins mutate or come into existence in the course of millennia. That completely new proteins—and, with them, new properties—can emerge practically out of nothing, was inconceivable for decades, in line with what the Greek philosopher Parmenides said: “Nothing can emerge from nothing” (ex nihilo nihil fit). Working with colleagues from the U.S. and Australia, researchers from the University of Münster (Germany) have now reconstructed how evolution forms the structure and function of a newly emerged protein in flies. This protein is essential for male fertility.https://phys.org/news/2021-03-proteins.html

3/28/2021 2:00 PMMethane raindrops on Titan could grow to be almost a centimeter across, nearly twice the size of large raindrops on Earth (about 6 millimeters). And, thanks to Titan’s thicker atmosphere and lower gravity, they would fall much more slowly, roughly 5.2 feet per second (1.6 m/s), the speed at which snowflakes fall on Earth (compared to rates of terrestrial rainfall at up to 30 ft/s [9 m/s]). The slower speed and larger drops would make it easier to see that raindrops (on Titan and Earth) tend to be distorted and flattened by the atmosphere as they fall.https://astronomy.com/magazine/ask-astro/2015/05/titanic-raindrops

In 2020, she won a Nobel Prize for that work, which dramatically strengthened the evidence that a supermassive black hole, invisible to our instruments, is lurking at the heart of the galaxy. She also became just the fourth woman to win the Nobel Prize in Physics in the award’s more than a century of history, a statistic she told Space.com she views as a responsibility.https://www.space.com/andrea-ghez-supermassive-black-hole-milky-way-diversity
4/11/2021 10:00 AMThe Laser Interferometer Gravitational-Wave Observatory (LIGO) is a pair of enormous research facilities in the United States dedicated to detecting ripples in the fabric of space-time known as gravitational waves.

4/11/2021 12:00 PMMachine vision systems have many applications, including self-driving cars, intelligent manufacturing, robotic surgery and biomedical imaging, among many others. Most of these machine vision systems use lens-based cameras, and after an image or video is captured, typically with a few megapixels per frame, a digital processor is used to perform machine-learning tasks, such as object classification and scene segmentation. Such a traditional machine vision architecture suffers from several drawbacks. First, the large amount of digital information makes it hard to achieve image/video analysis at high speed, especially using mobile and battery-powered devices. In addition, the captured images usually contain redundant information, which overwhelms the digital processor with a high computational burden, creating inefficiencies in terms of power and memory requirements. Moreover, beyond the visible wavelengths of light, fabricating high-pixel-count image sensors, such as what we have in our mobile phone cameras, is challenging and expensive, which limits the applications of standard machine vision methods at longer wavelengths, such as terahertz part of the spectrum.https://phys.org/news/2021-03-classification-single-pixel-detector.html

4/11/2021 4:00 PMIn a quantum theory of point particles, a fundamental quantity is the correlation function, which measures the probability for a particle to propagate from one point to another. The correlation function develops singularities when the two points are connected by light-like trajectories. In a flat spacetime, there is such a unique trajectory, but when spacetime is curved, there can be many light-like trajectories connecting two points. This is a result of gravitational lensing, which describes the effect of curved geometry on the propagation of light.https://phys.org/news/2021-03-theory-mystery-particles-black-hole.html

4/12/2021 10:00 AMWithin the realm of quantum mechanics, the generation of quantum entanglement remains one of the most challenging goals. Entanglement, simply put, is when the quantum state of each particle or a group of particles is not independent of the quantum states of other particles or groups, even over long distances. Entangled particles have always fascinated physicists, as measuring one entangled particle can result in a change in another entangled particle, famously dismissed as “spooky action at a distance” by Einstein. By now, physicists understand this strange effect and how to make use of it, for example to increase the sensitivity of measurements. However, entangled states are very fragile, as they can be easily disrupted by decoherence. Researchers have already created entangled states in atoms, photons, electrons and ions, but only recently have studies begun to explore entanglement in gases of polar molecules.https://phys.org/news/2021-03-theoretical-physicists-quantum-interactions-3d.html

4/14/2021 2:00 PMAbout 10 years ago, researchers at the University of Bonn produced an extreme aggregate photon state, a single “super-photon” made up of many thousands of individual light particles, and presented a completely new light source. The state is called an optical Bose-Einstein condensate and has captivated many physicists ever since, because this exotic world of light particles is home to its very own physical phenomena.

Fortuitously, Mingda Li—the Norman C. Rasmussen Assistant Professor of Nuclear Science and Engineering at MIT, who heads the department’s Quantum Matter Group—was already thinking along similar lines.

4/16/2021 8:00 AMBees are perhaps the insects that most arouse our fascination and curiosity. With the exception of Antarctica, they are found on all continents, in all habitats that contain insect-pollinated flowering plants. Representations of humans collecting honey from wild bees date back to 15,000 years ago, and pots of honey have even been found in the tombs of Egyptian pharaohs like Tutankhamen. Although we generally have a fixed idea about what cartoon bees look like, there are thousands of species around the world, with different sizes, colors and behaviors. There are even several examples of solitary bees, many without stingers, and even some species that survive by plundering other weaker colonies. But something that has consistently impressed researchers is the organization of their hives, which are truly highly populated cities with an efficiency to make any urban planner envious.https://www.archdaily.com/946778/the-incredible-architecture-of-bees

4/21/2021 8:00 AMBelow the verdant surface and organic rich soil, life extends kilometers into Earth’s deep rocky crust. The continental deep subsurface is likely one of the largest reservoirs of bacteria and archaea on Earth, many forming biofilms—like a microbial coating of the rock surface. This microbial population survives without light or oxygen and with minimal organic carbon sources, and can get energy by eating or respiring minerals. Distributed throughout the deep subsurface, these biofilms could represent 20-80% of the total bacterial and archaeal biomass in the continental subsurface according to the most recent estimate. But are these microbial populations spread evenly on rock surfaces, or do they prefer to colonize specific minerals in the rocks?https://phys.org/news/2021-04-earth-crust-mineralogy-hotspots-intraterrestrial.html

4/21/2021 6:00 PMTwo teams of researchers have independently found that there exists a certain type of graphene system where electrons freeze as the temperature rises. The first team, with members from Israel, the U.S. and Japan, found that placing one layer of graphene atop another and then twisting the one on top resulted in a graphene state in which the electrons would freeze as temperatures rose. And in attempting to explain what they observed, they discovered that the entropy of the near-insulating phase was approximately half of what would be expected from free-electron spins. The second team, with members from the U.S., Japan and Israel, found the same graphene system and in their investigation to understand their observations, they noted that a large magnetic moment arose in the insulator. Both teams have published their results in the journal Nature.

In this context, a team of researchers led by Borja Toledo Padrón, a Severo Ochoa-La Caixa doctoral student at the Instituto de Astrofísica de Canarias (IAC), specializing in the search for planets around this type of stars, has discovered a super-Earth orbiting the star GJ 740, a red dwarf star situated some 36 light years from the Earth.https://phys.org/news/2021-04-super-earth-orbiting-red-dwarf-star.html
4/26/2021 6:00 PMWhy is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and Utrecht University (Netherlands) has now been able to show, there is a class of very special light waves for which this does not apply: for any specific disordered medium—such as the sugar cube you may just have put in your coffee—tailor-made light beams can be constructed that are practically not changed by this medium, but only attenuated. The light beam penetrates the medium, and a light pattern arrives on the other side that has the same shape as if the medium were not there at all.https://phys.org/news/2021-04-penetrate-opaque-materials.html

4/28/2021 6:00 PMThe observation that most of the viruses that cause human disease come from other animals has led some researchers to attempt “zoonotic risk prediction” to second-guess the next virus to hit us. However, in an Essay in the open access journal PLOS Biology, led by Dr. Michelle Wille at the University of Sydney, Australia with co-authors Jemma Geoghegan and Edward Holmes, it is proposed that these zoonotic risk predictions are of limited value and will not tell us which virus will cause the next pandemic. Instead, we should target the human-animal interface for intensive viral surveillance.https://phys.org/news/2021-04-pandemic-virus-harder.html
4/29/2021 8:00 AMIt has been known for about a year that minks can become infected with SARS-CoV-2. The virus had been transmitted from humans to farmed mink and mutated in infected animals. Mutations were acquired in the spike protein, which is crucial for the entry of the virus into host cells and represents the central point of attack for antibodies. These SARS-CoV-2 variants from mink were transmitted back to humans, raising concerns that minks could be a continuing source of infection of humans with SARS-CoV-2 variants with altered biological properties. Researchers at the German Primate Center (DPZ) – Leibniz Institute for Primate Research in Göttingen, Germany, have now shown that an antibody used for COVID-19 therapy is unable to effectively inhibit SARS-CoV-2 harboring a spike mutation acquired in minks. In addition, the mutation reduced the inhibition of the virus by antibodies produced in SARS-CoV-2 infected humans. These results show that SARS-CoV-2 can acquire mutations in minks that may reduce control of the virus by the human immune system.https://phys.org/news/2021-04-sars-cov-variants-mink-evade-inhibition.html

5/5/2021 8:00 AMIn 1994, physicist Miguel Alcubierre proposed a radical technology that would allow faster than light travel: the warp drive, a hypothetical way to skirt around the universe’s ultimate speed limit by bending the fabric of reality. It was an intriguing idea — even NASA has been researching it at the Eagleworks laboratory — but Alcubierre’s proposal contained problems that seemed insurmountable. Now, a recent paper by US-based physicists Alexey Bobrick and Gianni Martire has resolved many of those issues and generated a lot of buzz. But while Bobrick and Martire have managed to substantially demystify warp technology, their work actually suggests that faster-than-light travel will remain out of reach for beings like us, at least for the time being.https://www.space.com/warp-drive-research-dashes-faster-than-light-travel-dreams

5/12/2021 4:00 PMMammals see with their eyes, hear with their ears and smell with their nose. But which sense or organ allows them to orient themselves on their migrations, which sometimes go far beyond their local foraging areas and therefore require an extended ability to navigate? Scientific experiments led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), published together with Prof. Richard A. Holland (Bangor University, UK) and Dr. Gunārs Petersons (Latvia University of Life Sciences and Technologies) now show that the cornea of the eyes is the location of this important sense in migrating bats. If the cornea is anesthetized, the otherwise reliable sense of orientation is disturbed while light detection remains unimpaired. The experiment suggests the localisation of a magnetic sense in mammals.https://phys.org/news/2021-05-cryptic-localized-sixth-mammals-lies.html

5/16/2021 6:00 PMLarge amounts of gas are sometimes funneled to a galaxy’s nuclear regions, with profound consequences. The gas triggers starburst activity and can also feed the supermassive black hole, converting it into an active galactic nucleus (AGN); indeed the supermassive black holes in AGN are thought to gain most of their mass in these accretion events. Eventually, outward pressure from supernovae, shocks, and/or AGN activity terminate the inflow. Galaxy mergers are thought to be one mechanism capable of triggering these massive inflows by disrupting the medium. A less dramatic cause may result from gas flows induced by a combination of galactic rotation and the gravitational instabilities generated by galactic bars, the elongated central structures (composed of stars) found in numerous spiral galaxies including the Milky Way.https://phys.org/news/2021-05-barred-galaxy-massive-molecular-inflow.html

5/20/2021 10:00 AMOne third of the proteins essential for life processes are produced in the endoplasmic reticulum (ER) of the cell and distributed via membrane vesicles. Sorting of proteins at ER exit sites and transport to the Golgi apparatus is orchestrated by the so-called COPII protein coat complexes, but not as previously thought. Researchers at Tel Aviv University (TAU), Israel, and the Leibniz Institute on Aging—Fritz Lipmann Institute (FLI) in Jena, Germany, have now found that the COPII complexes do not leave the ER for transport. They remain as gatekeepers at ER exit sites from where they control the protein recruitment, sorting and exit to the Golgi. The new findings could lead to a paradigm shift in cell biology.https://phys.org/news/2021-05-paradigm-cell-biology-protein-thought.html

Europa is under a constant gravitational assault. As it orbits, Europa’ ice’ surface squeezed and stretched with due to Jupiter’s gravity creating enough heat, scientist think, to support a global ocean beneath the moon solid shell.https://www.cosmosup.com/ice-crust-in-europa-hotter/
5/23/2021 10:00 AMOne of the most prominent evils of rapid industrialization has been the emission of toxic pollutants into the surrounding biosphere, with often disastrous consequences for human beings. Several industrial processes, such as chemical manufacturing and printing, along with facilities such as power plants emit volatile organic compounds (VOCs) that are known to be cancer-causing and raise an important environmental issue in need of a solution. Traditionally, VOCs are controlled via a process called catalytic oxidation, in which they are converted into benign materials in the presence of noble metal (e.g. gold, silver, and platinum) nanoparticles. However, the process is expensive and requires a fine-tuning of nanoparticle characteristics. Thus, a catalytic process not requiring noble metal catalysts is highly desirable. While transition metals and their oxides are a possible alternative, they require complex syntheses and precise chemical composition control.https://phys.org/news/2021-05-bone-deep-mineral-human-bone-toxic.html

5/23/2021 6:00 PMOne of the most basic structural aspects of relativistic spacetime is the description of how time and distances are altered by motion. The theory of special relativity describes a spacetime framework for linear constant motion in which time dilates and lengths contract in response to motion. This framework is described by the Lorentz transformation, which encompasses mathematical formulas that describe how time and distance are altered between moving reference frames. The Lorentz transformation also describes how a stationary observer views time in the moving frame to be offset with distance. The offsetting of time with distance between reference frames generates differential simultaneity, in which events that are simultaneous for one observer will not be simultaneous for a second observer moving relative to the first observer.https://phys.org/news/2021-05-optical-reveal-basic-spacetime-rotating.html

5/29/2021 4:00 PMWhen a piece of conducting material is heated up at one of its ends, a voltage difference can build up across the sample, which in turn can be converted into a current. This is the so-called Seebeck effect, the cornerstone of thermoelectric effects. In particular, the effect provides a route to creating work out of a temperature difference. Such thermoelectric engines do not have any movable part and are therefore convenient power sources in various applications, including propelling NASA’s Mars rover Perseverance. The Seebeck effect is interesting for fundamental physics, too, as the magnitude and sign of the induced thermoelectric current is characteristic of the material and indicates how entropy and charge currents are coupled. Writing in Physical Review X, the group of Prof. Tilman Esslinger at the Department of Physics of ETH Zurich now reports on the controlled reversal of such a current by changing the interaction strength among the constituents of a quantum simulator made of extremely cold atoms trapped in shaped laser fields. The capability to induce such a reversal means that the system can be turned from a thermoelectric engine into a cooler.https://phys.org/news/2021-05-current-trend-reversed-scientists-seebeck.html

5/30/2021 2:00 PMAll modern life is composed of cells, from single-celled bacteria to more complex organisms such as humans, which may contain billions or even trillions of cells. But how life came to be cellular remains uncertain. New research led by specially appointed assistant professor Tony Z. Jia at the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology, along with colleagues from around the world (Japan, Malaysia, France, Czech Republic, India and the U.S.), shows that simple chemical compounds known as hydroxy acids, which were likely common on primitive Earth, spontaneously link together and form structures reminiscent of modern cells when dried from solution, as may have happened on or in ancient beaches or puddles. The resulting structures may have helped scaffold the emergence of biological cellularity, and offer scientists a new avenue for studying early proto-biological evolution and the origins of life itself.https://phys.org/news/2021-05-life-cellular-unusual-molecules.html

While these disks may differ in size, they’re all mostly dependent on the mighty force of gravity, which keeps them spinning around the central mass. Gravity lets small clumps grow into bigger clumps. But it’s not enough to pull the whole disk into the middle in one giant clump, because angular momentum is pulling those clumps away from the center as they spin.https://astronomy.com/news/2019/02/scientists-finally-confirm-a-big-theory-about-solar-system-formation

While many stars change in brightness because they pulsate or are eclipsed by another star in a binary system, it’s exceptionally rare for a star to become fainter over a period of several months and then brighten again.https://phys.org/news/2021-06-astronomers-giant-center-galaxy.html
6/21/2021 10:00 AMHumanity has yet to find extraterrestrial life, but a new study suggests that the exomoons of ‘rogue planets’ could be a good place to look.

Electron emission after light absorption was already explained by Albert Einstein. But since this effect is a highly complex process, scientists have still not been able to fully elucidate its details. Prof. Dr. Bernd von Issendorff and his team at the University of Freiburg’s Institute of Physics have now succeeded in detecting a previously unknown quantum effect in the angular distributions of photoelectrons from cryogenic mass-selected metal clusters. The angular distributions resemble those of classical particles, a behavior that is surprisingly explainable by the strong electron-electron interaction in these many-electron systems.https://phys.org/news/2021-06-electron-merry-go-round-mechanism-classical-behavior.html

6/24/2021 6:00 PMSupermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young. For example, a billion solar mass black holes are found when the universe was just 6% of its current age, 13.7 billion years. How do these SMBHs in the early universe originate? A team led by a theoretical physicist at the University of California, Riverside, has come up with an explanation: A massive seed black hole that the collapse of a dark matter halo could produce.https://phys.org/news/2021-06-seed-black-hole-dark-halo.html

6/25/2021 4:00 PMIn the mid-14th century Europe was devastated by a major pandemic—the Black Death—which killed between 40 and 60 per cent of the population. Later waves of plague then continued to strike regularly over several centuries. Plague kills so rapidly it leaves no visible traces on the skeleton, so archaeologists have previously been unable to identify individuals who died of plague unless they were buried in mass graves. Whilst it has long been suspected that most plague victims received individual burial, this has been impossible to confirm until now.https://phys.org/news/2021-06-evidence-medieval-plague-victims-considerable.html

6/28/2021 6:00 PMFor many years now, astronomers and physicists have been in a conflict. Is the mysterious dark matter that we observe deep in the Universe real, or is what we see the result of subtle deviations from the laws of gravity as we know them? In 2016, Dutch physicist Erik Verlinde proposed a theory of the second kind: emergent gravity. New research, published in Astronomy & Astrophysics, pushes the limits of dark matter observations to the unknown outer regions of galaxies, and in doing so re-evaluates several dark matter models and alternative theories of gravity. Measurements of the gravity of 259,000 isolated galaxies show a very close relation between the contributions of dark matter and those of ordinary matter, as predicted in Verlinde’s theory of emergent gravity and an alternative model called Modified Newtonian Dynamics. However, the results also appear to agree with a computer simulation of the Universe that assumes that dark matter is ‘real stuff’.https://phys.org/news/2021-06-dark-real-misunderstood-gravity.html

7/7/2021 2:00 PMEarth’s climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.https://climate.nasa.gov/evidence/
7/7/2021 4:00 PMFor many years now, astronomers and physicists have been in a conflict. Is the mysterious dark matter that we observe deep in the Universe real, or is what we see the result of subtle deviations from the laws of gravity as we know them? In 2016, Dutch physicist Erik Verlinde proposed a theory of the second kind: emergent gravity. New research, published in Astronomy & Astrophysics this week, pushes the limits of dark matter observations to the unknown outer regions of galaxies, and in doing so re-evaluates several dark matter models and alternative theories of gravity. Measurements of the gravity of 259,000 isolated galaxies show a very close relation between the contributions of dark matter and those of ordinary matter, as predicted in Verlinde’s theory of emergent gravity and an alternative model called Modified Newtonian Dynamics. However, the results also appear to agree with a computer simulation of the Universe that assumes that dark matter is ‘real stuff’.https://phys.org/news/2021-06-dark-real-misunderstood-gravity.html

7/10/2021 2:00 PMAt the dark hearts of galaxies like the Milky Way lie supermassive black holes, with millions or even billions of times the sun’s mass. Some of those supermassive black holes are what scientists call active galactic nuclei (AGN), which spew out copious amounts of radiation like X-rays and radio waves. AGN are responsible for the twin jets of ionized gas you see shooting away in pictures of many galaxies. As all things must pass, so too must every AGN one day shut off. But scientists have never quite understood how or when that happens. Now, researchers led by Kohei Ichikawa, an astronomer at Tohoku University in Sendai, Japan, may have found a clue. Looking at the distant galaxy Arp 187, those researchers have seen what they think is an AGN in its very last days.https://www.space.com/dying-supermassive-black-hole-light-echo
7/10/2021 4:00 PMSince 1880, the Earth’s average surface temperature has risen by 0.07°C (0.13°F) every decade. That number alone may seem negligible, but over time, it adds up. In addition, the rate of temperature change has grown significantly more dramatic over time—more than doubling to 0.18°C (0.32°F) since 1981. As a result of this global warming process, environmental crises have become the most prominent risks of our time. In this global temperature graph, climate data scientist Neil R.

7/15/2021 6:00 PMNASA’s next big space telescope just took a big step forward toward its planned launch this fall. The $9.8 billion James Webb Space Telescope mission has passed a key launch review, keeping it on track to lift off atop an Ariane 5 rocket before the end of the year, European Space Agency (ESA) officials announced last week.https://www.space.com/james-webb-space-telescope-passes-launch-review
7/16/2021 8:00 AMThe pumpkin toadlet (Brachycephalus ephippium) of Brazil is flaming orange, smaller than a nickel, and deaf to the mating calls of its own species. How the diminutive amphibians found mates amid the leafy chaos of the rainforest floor was a mystery. Now, scientists searching for answers to this acoustic riddle have discovered something unexpected: This toadlet glows, Mongabay reports. The pumpkin toadlet’s back and head glowed blue under ultraviolet (UV) light, researchers reported last week in Scientific Reports. This UV light show could help these toadlets find love in the dark, but researchers still need to figure out whether the frogs can see it. The glow also comes from a surprising source: a fluorescent skeleton shining through translucent patches of the frog’s skin. If the pumpkin toadlet can’t see UV light, researchers speculate that the glowing bones may serve to warn would-be predators of the toadlet’s toxicity.https://www.sciencemag.org/news/2019/04/scientists-discover-frog-glowing-bones
7/16/2021 10:00 AMIn a series of breakthrough papers, theoretical physicists have come tantalizingly close to resolving the black hole information paradox that has entranced and bedeviled them for nearly 50 years. Information, they now say with confidence, does escape a black hole. If you jump into one, you will not be gone for good. Particle by particle, the information needed to reconstitute your body will reemerge. Most physicists have long assumed it would; that was the upshot of string theory, their leading candidate for a unified theory of nature. But the new calculations, though inspired by string theory, stand on their own, with nary a string in sight. Information gets out through the workings of gravity itself—just ordinary gravity with a single layer of quantum effects.https://www.wired.com/story/the-black-hole-information-paradox-comes-to-an-end/

7/16/2021 2:00 PMMost biological traits are inherited via genes, but there are exceptions to this rule. Two teams from the University of Geneva (UNIGE) have been investigating the location of centromeres—specific sites on chromosomes that are essential for cell division. They found that in the small worm Caenorhabiditis elegans, the transmission of the correct location of these sites to the offspring is not mediated by genes, but by an epigenetic memory mechanism.https://phys.org/news/2021-07-inherited-memories-chromosomal-site.html
7/16/2021 4:00 PMFor the hundreds of millions of people living in coastal regions around the world, rising seas driven by climate change pose a direct threat. In order for authorities to plan appropriate protection strategies, accurate information on sea-level rise close to the coast is imperative. For various reasons, these measurements are difficult to get from satellites. However, new ESA-funded research demonstrates how a specific way of processing satellite altimetry data now makes it possible to determine sea-level change in coastal areas with millimetre per year accuracy, and even if the sea is covered by ice.https://www.esa.int/Applications/Observing_the_Earth/New_satellite_data_techniques_reveal_coastal_sea-level_rise

7/17/2021 8:00 AMThe methane wafting from Enceladus may be a sign that life teems in the Saturn moon’s subsurface sea, a new study reports. In 2005, NASA’s Cassini Saturn orbiter discovered geysers blasting particles of water ice into space from “tiger stripe” fractures near Enceladus’ south pole. That material, which forms a plume that feeds Saturn’s E ring (the planet’s second-outermost ring), is thought to come from a huge ocean of liquid water that sloshes beneath the moon’s icy shell.https://www.space.com/methane-plume-enceladus-possible-sign-alien-life
7/17/2021 10:00 AMAmphipods—small, shrimplike crustaceans in most aquatic ecosystems—start to fall apart once they hit depths of 4500 meters. There, a combination of crushing pressures, low temperature, and higher acidity causes the calcium carbonate in their exoskeletons to dissolve, making them vulnerable to pressure and predators. Now, scientists have discovered how one species, Hirondellea gigas, can survive in the deepest part of the ocean: with aluminum suits of armor.https://www.sciencemag.org/news/2019/04/shrimplike-creature-makes-aluminum-armor-survive-deep-sea-s-crushing-pressure

7/18/2021 2:00 PMScientists know that the Earth was bombarded by huge impactors in distant time, but a new analysis suggests that the number of these impacts may have been 10 times higher than previously thought. This translates into a barrage of collisions—similar in scale to that of the asteroid strike that wiped out the dinosaurs—on average every 15 million years between 2.5 and 3.5 billion years ago. Some of these individual impacts may have been much bigger, possibly ranging from city-sized to small province sized. Researchers are also considering what effect the impacts may have had on the Earth’s evolving near-surface chemistry.

7/26/2021 4:00 PMWith its global subsurface water ocean, Saturn’s moon Enceladus is considered to be one of the best places to search for life. Now, new research from a team of biologists suggests life on Enceladus might indeed be quite possible … and that we might already have evidence for it. Something is producing a lot of methane on Enceladus, or rather in its subsurface ocean. And methane can be a life sign. Charlie Wood discussed these curious results on June 8, 2021, in Popular Science. Intriguingly, according to Wood’s article, initial analysis suggests the methane is being produced in a way similar to methanogenic microbes in oceans on Earth.https://earthsky.org/space/methane-on-enceladus-methanogens/

8/5/2021 12:00 PMPlace one clock at the top of a mountain. Place another on the beach. Eventually, you’ll see that each clock tells a different time. Why? Time moves slower as you get closer to Earth, because, as Einstein posited in his theory of general relativity, the gravity of a large mass, like Earth, warps the space and time around it. Scientists first observed this “time dilation” effect on the cosmic scale, such as when a star passes near a black hole. Then, in 2010, researchers observed the same effect on a much smaller scale, using two extremely precise atomic clocks, one placed 33 centimeters higher than the other. Again, time moved slower for the clock closer to Earth.https://bigthink.com/surprising-science/time-perception

8/8/2021 2:00 PMThroughout the 20th century, a number of discoveries revolutionized our Universe. The discovery of the interior structure of atoms as well as radioactivity led to the quantum revolution, exposing the bizarre and counterintuitive rules that nature plays by at a fundamental level. The birth and growth of experimental particle physics led to enormous theoretical developments, enabling everything we observe to be represented as composites of indivisible quanta. At last, in the late 1960s, the final theoretical pieces of our quantum Universe were put into place, completing what we know today as the Standard Model. More than half a century later, every prediction it’s ever made has been borne out by experiments, with no conflicts at all.https://www.forbes.com/sites/startswithabang/2021/07/27/the-standard-model-is-an-orphan-theory-now/
8/8/2021 4:00 PMAn international team of astrophysicists from the Instituto de Astrofísica de Canarias (IAC), the University of La Laguna (ULL) and the Space Telescope Science Institute (STScI, U.S.) has discovered the presence of transverse rotation (in the plane of the sky) in three dwarf spheroidal galaxies. These are a very faint type of galaxy and are quite difficult to observe. These new findings help to trace their evolutionary history. The finding was made using the most recent data from the GAIA satellite of the European Space Agency.https://phys.org/news/2021-07-dwarf-spheroidal-galaxies-rotate.html
8/8/2021 6:00 PMJennifer Toussaint, chief of animal control in Arlington, Virginia, can’t forget the four baby blue jays. In late May, worried residents had delivered the fledglings to her clinic just outside of Washington, D.C., within just a few hours. Each was plump, indicating “their parents had done a great job caring for them,” Toussaint says. But the birds were lethargic, unable to keep their balance, and blinded by crusty, oozing patches that had grown over their eyes.https://www.sciencemag.org/news/2021/07/songbirds-are-mysteriously-dying-across-eastern-us-scientists-are-scrambling-find-out

8/9/2021 12:00 PMWhen a star like our sun gets to be old, in another seven billion years or so, it will no longer be able to sustain burning its nuclear fuel. With only about half of its mass remaining it will shrink to a fraction of its radius and become a white dwarf star. White dwarf stars are common; over 95% of all stars will become white dwarfs. The most famous one is the companion to the brightest star in the sky, Sirius, but more particularly all stars known to host exoplanets will also end their lives as white dwarfs.https://phys.org/news/2021-07-planetary-remnants-white-dwarf-stars.html
8/9/2021 2:00 PMFor the past 50 years, manufacturers have considered carbon fiber a dream material: Though individual fibers are thinner than a strand of human hair, they can be twisted together and fused with a matrix material to form a lightweight composite that is stronger than steel, twice as stiff and a good conductor of heat. And, unlike metals, the material doesn’t crack over time. It’s been used in a wide range of applications, including air and spacecraft, cars, buildings, medical devices and sports equipment.https://phys.org/news/2021-07-simple-inexpensive-method-carbon-fiber.html
8/9/2021 4:00 PMUntil recently it was thought neutron-star mergers were the only way heavy elements (heavier than zinc) could be produced. These mergers involve the mashup of the remnants of two massive stars in a binary system. But we know heavy elements were first produced not long after the Big Bang, when the universe was really young. Back then, not enough time had passed for neutron star mergers to have even occurred. Thus, another source was needed to explain the presence of early heavy elements in the Milky Way.https://www.space.com/supernova-explosion-heavy-metals-in-milky-way

8/16/2021 8:00 AMRecent record-breaking rainfall across the northeastern United States is part of a larger trend. From Maine to West Virginia, the Northeast has seen an abrupt increase in extreme precipitation—heavy rain and snow resulting in about 1 to 2 inches of water in a day depending on location since 1996, which has coincided with warming sea surface temperatures in the North Atlantic. Northeast extreme precipitation is typically caused by tropical cyclones, thunderstorms along fronts, and extratropical cyclones like Nor’easters. A recent study published in Weather and Climate Extremes finds that the increase in extreme precipitation after 1996 was caused by greenhouse gases from human activity and surface temperature variability of the North Atlantic Ocean, known as Atlantic variability.https://phys.org/news/2021-08-extreme-precipitation-northeast-atlantic-variability.html

8/23/2021 8:00 AMThe interplay between light and matter encompasses a stunning spectrum of phenomena, from photosynthesis to the captivating colors of rainbows and butterfly wings. Diverse as these manifestations may be, they involve very weak light-matter coupling—in essence, light interacts with the material system but does not change its basic properties. A distinctively different set of phenomena arises, however, for systems that are artifically engineered to maximize light-matter coupling. Then intriguing quantum states can emerge that are neither light nor matter, but a hybrid of the two. Such states are of high interest from a fundamental point of view as well as for creating novel functionalities, for instance for enabling interactions between photons. The strongest couplings to date have been realized with semiconductor materials confined to tiny photonic cavities. In these devices the coupling is typically increased by making the cavity ever smaller. But even if associated fabrication challenges can be addressed, the approach is about to encounter fundamental physical limits, as a team led by Professors Giacomo Scalari and Jérôme Faist at the Institute of Quantum Electronics report in a paper published today in Nature Photonics. With this work, they set quantitative limits to the miniaturization of such nanophotonic devices.https://phys.org/news/2021-08-exploring-limits-light-matter-coupling-nanoscale.html

8/25/2021 8:00 AMFor almost a century, astronomers have known that the universe is expanding. Space-time is stretching itself out over billions of light-years, carrying the galaxies within it apart, like raisins embedded within a rising loaf of bread. This steady expansion, pitted against the cosmos’ urge to collapse under its own gravity, means there are two main scenarios for how the universe will eventually end. These scenarios are dubbed the Big Crunch — where gravity overcomes expansion and the Big Bang occurs in reverse — and the Big Freeze — where gravity loses out to the expansion and all matter is isolated by unfathomable distances.https://astronomy.com/magazine/news/2021/02/the-beginning-to-the-end-of-the-universe-the-mystery-of-dark-energy
8/25/2021 10:00 AMOne of the enduring enigmas of Mercury is why such a small planet, roughly 38 percent of Earth’s diameter, is so dense. From Mariner 10’s 1974–5 flybys of the innermost world and now the orbiting MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft, we know Mercury has an average density of 5.43 grams per cubic centimeter. (Earth’s average density is 5.52 g/cm3.) This value means the planet must hold a high percentage of iron because the rocky surface material is much less dense than the planet’s average. New results from MESSENGER indicate that the metallic core likely makes up more than 80 percent of Mercury’s diameter.https://astronomy.com/magazine/ask-astro/2012/11/weighty-world
8/25/2021 12:00 PMUranus and Neptune are called ice giants because they are smaller and compositionally different from Jupiter and Saturn, the gas giants. Jupiter and Saturn are composed of mostly hydrogen and helium, with large mantles of metallic hydrogen (which acts like a metal, due to the pressure and temperature within these planets) and only small cores of rock and ice. This is why they are called gas giants: They are mostly gaseous, with very little rock and ice.https://astronomy.com/magazine/ask-astro/2019/06/why-do-astronomers-call-uranus-and-neptune-ice-giants

8/26/2021 10:00 AMMeet the Japanese giant hornet: massive, extremely aggressive, and a honey bee’s worst nightmare. A single giant hornet can kill 40 European honey bees in one minute, and a group of 30 could wipe out an entire hive of 30,000 European honey bees in little more than three hours. Growing up to 2 inches in length, with a wingspan of 2.5 inches, these giants are about 5 times larger than the average bee. When they attack a hive, they quickly decapitate and dismember the inhabitants — flying off with the bees’ thoraxes, as well as honey and bee larvae, which they feed to their young.https://roaring.earth/honeybees-vs-hornets/

8/29/2021 10:00 AMMore than a decade ago, the world’s most energetic laser started to unleash its blasts on tiny capsules of hydrogen isotopes, with managers promising it would soon demonstrate a route to limitless fusion energy. Now, the National Ignition Facility (NIF) has taken a major leap toward that goal. Last week, a single laser shot sparked a fusion explosion from a peppercorn-size fuel capsule that produced eight times more energy than the facility had ever achieved: 1.35 megajoules (MJ)—roughly the kinetic energy of a car traveling at 160 kilometers per hour. That was also 70% of the energy of the laser pulse that triggered it, making it tantalizingly close to “ignition”: a fusion shot producing an excess of energy.https://www.sciencemag.org/news/2021/08/explosive-new-result-laser-powered-fusion-effort-nears-ignition

9/2/2021 6:00 PMComet 67P/Churyumov-Gerasimenko is half the density of water. This density implies a high porosity in the range of 70 to 80 percent, depending on the assumed dust-to-ice ratio. (You can use 0.9 gram per centimeter for ice and 1.5 to 2 grams per centimeter density for the dust.) Other comets show densities similar to 67P, but those have been less accurately determined during high-velocity spacecraft flybys and via the plume ejected by the impactor of NASA’s Deep Impact mission. Thus, we can infer that cometary material is made of weakly bonded icy dust aggregates with high porosity and low strength.https://astronomy.com/magazine/ask-astro/2015/06/boulders-on-comets

9/9/2021 12:00 PMAn object crossing a black hole’s event horizon, the point of no return, will simply pass through from its own perspective, unaffected by time dilation. However, its appearance to outside observers is strongly affected by the black hole’s presence. Light signals sent from the object at even time intervals (from the object’s perspective) will be received further and further apart in time as the object approaches the event horizon. The strong gravitational field near the event horizon curves space, increasing the distance light must travel to reach the observer. The curvature and distance to the observer — and hence the signal’s travel time — approach infinity at the event horizon, so an outside observer will never see an object actually fall into a black hole. The object instead will appear to freeze at the event horizon.https://astronomy.com/magazine/ask-astro/2014/11/frozen-stars

9/10/2021 8:00 AMIn the summer of 2018, a hobby drone dropped a small package near the lip of Stromboli, a volcano off the coast of Sicily that has been erupting almost constantly for the past century. As one of the most active volcanoes on the planet, Stromboli is a source of fascination for geologists, but collecting data near the roiling vent is fraught with peril. So a team of researchers from the University of Bristol built a robot volcanologist and used a drone to ferry it to the top of the volcano, where it could passively monitor its every quake and quiver until it was inevitably destroyed by an eruption. The robot was a softball-sized sensor pod powered by microdoses of nuclear energy from a radioactive battery the size of a square of chocolate.

9/15/2021 8:00 AMWe are all prisoners of our background and experience. What each of us considers normal is based on our lifelong encounters. The materials we relate to and find familiar range from the thinness of mountain air to the high density of iron, as in trying to budge the anchor of a friend’s boat. Rarely do we venture outside this envelope and encounter Earth’s highest-density elements, which are twice iron’s weight.

Achieving a better understanding of how such systems with many particles evolve in time is a frontier of quantum physics. The result could greatly simplify the study of quantum systems that have been excited out of equilibrium. Besides its fundamental importance, it could eventually inform the development of quantum-based technologies, which include quantum computers and simulators, quantum communication, and quantum sensors.https://phys.org/news/2021-09-theory-many-particle-quantum.html
9/19/2021 8:00 AMIn a remote galaxy, two neutron stars circled one another in a ballet of ultimate destruction and inevitable creation. Both objects were the remnants of massive stars, probably from a binary system, that had become supernovae long before. Each was incredibly massive, with neutrons so closely packed that their cores became diamond. The dance, alas, could not go on forever and the stars collided, releasing unimaginable energy and sending gravitational waves speeding through the fabric of space-time.https://astronomy.com/magazine/news/2020/11/does-all-the-gold-in-the-universe-come-from-stars

9/19/2021 2:00 PMYears ago, planetary scientists thought of Venus as Earth’s sister planet. Similar in size, both close to the Sun, both rocky bodies, Earth and Venus were practically considered two of a kind. That abruptly changed, however, when astronomers got their first close-up look at Venus. The moment arrived in 1962, when Mariner 2 flew by the planet, and far more forcefully in 1970, when Venera 7 touched down on the hellishly hot surface. Not only do surface temperatures on our sister planet exceed 750° F (400° C), but Venus’ thick carbon-dioxide atmosphere produces a greenhouse effect that hosts sulfur-dioxide and sulfuric-acid clouds. It’s not a friendly environment for living things of any sort.https://astronomy.com/magazine/greatest-mysteries/2019/07/33-why-did-venus-turn-itself-inside-out

However, according to two new studies—one experimental and the other theoretical—that are the outcome of the collaboration between the groups of Prof. Talila Volk of the Molecular Genetics Department and Prof. Sam Safran of the Chemical and Biological Physics Department at the Weizmann Institute of Science, this image should be reconsidered. Clarifying it is essential since DNA’s spatial arrangement in the nucleus can affect the expression of genes contained within the DNA molecule, and hence the proteins found in the cell.https://phys.org/news/2021-09-imaging-method-reveals-dna-cell.html

10/1/2021 12:00 PMDespite a plethora of archaeological research over the past century, the timing of human migration into the Americas is still far from resolved. In a study of exposed outcrops of Lake Otero in White Sands National Park in New Mexico, Bennett et al. reveal numerous human footprints dating to about 23,000 to 21,000 years ago. These finds indicate the presence of humans in North America for approximately two millennia during the Last Glacial Maximum south of the migratory barrier created by the ice sheets to the north. This timing coincided with a Northern Hemispheric abrupt warming event, Dansgaard-Oeschger event 2, which drew down lake levels and allowed humans and megafauna to walk on newly exposed surfaces, creating tracks that became preserved in the geologic record.https://www.science.org/doi/abs/10.1126/science.abg7586

10/14/2021 6:00 PMFor a quarter of a century, Wolfgang Pauli’s prediction remained an educated guess. In 1930, the Austrian physicist predicted the existence of a ghostly new subatomic particle. After observing beta decay in a radioactive nucleus, Pauli noted that an undiscovered particle must exist to explain the resulting spectrum. During beta decay, a proton becomes a neutron by emitting a positron. But Pauli argued the nucleus also emitted an unknown electrically neutral particle. He thought this hypothetical particle had less than 1 percent of a proton’s mass.https://astronomy.com/magazine/greatest-mysteries/2019/07/50-do-neutrinos-hold-secrets-to-the-cosmos
10/15/2021 8:00 AMIn December 2020 a 40-centimetre steel capsule parachuted to Earth, landing next to a bush in the remote Australian outback. Inside the capsule were rock samples from an ancient asteroid that formed during the earliest days of our solar system. To gather those rocks, the Japanese spacecraft Hayabusa2, spent six years traveling 3.2 billion kilometres to the asteroid, Ryugu, which orbits between Earth and Mars, blew a hole in it with a copper cannonball, sampled rock from the blast site, and made the long journey back to Earth. Those rocks could help reveal the source of the water that ultimately filled our oceans.https://www.nature.com/articles/d42473-021-00388-w

10/15/2021 12:00 PMScientists have developed a groundbreaking theory for calculating what’s happening inside a proton traveling at the speed of light. For more than 2,000 years, scientists thought the atom was the smallest particle possible. Then, they discovered that it has a nucleus made up of protons and neutrons surrounded by electrons. After that, they found that the protons and neutrons themselves have a complex inner world full of quarks and antiquarks held together by a superglue-like force created by gluons.https://phys.org/news/2021-10-proton.html

10/16/2021 6:00 PMThe universe was created about 13.8 billion years ago in a blaze of light: the big bang. Roughly 380,000 years later, after matter (mostly hydrogen) had cooled enough for neutral atoms to form, light was able to traverse space freely. That light, the cosmic microwave background (CMB) radiation, comes to us from every direction in the sky uniformly … or so it first seemed. In the last decades astronomers have discovered that the radiation has faint ripples and bumps in it at a level of brightness of only a part in one hundred thousand—the seeds for future structures, like galaxies.https://phys.org/news/2021-10-latest-results-cosmic-microwave-background.html

10/18/2021 4:00 PMSometime 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 ensuing millennia has been a mystery. Now, in the most comprehensive comparison yet of ancient dog and human DNA, scientists are starting to fill in some of the blanks, revealing where dogs and humans traveled together—and where they may have parted ways.https://www.science.org/content/article/how-dogs-tracked-their-humans-across-ancient-world

10/19/2021 12:00 PMDomestic cats and other felids rub their faces and heads against catnip (Nepeta cataria) and silver vine (Actinidia polygama) and roll on the ground as a characteristic response. While this response is well known, its biological function and underlying mechanism remain undetermined. Here, we uncover the neurophysiological mechanism and functional outcome of this feline response. We found that the iridoid nepetalactol is the major component of silver vine that elicits this potent response in cats and other felids. Nepetalactol increased plasma β-endorphin levels in cats, while pharmacological inhibition of μ-opioid receptors suppressed the classic rubbing response. Rubbing behavior transfers nepetalactol onto the faces and heads of respondents where it repels the mosquito, Aedes albopictus. Thus, self-anointing behavior helps to protect cats against mosquito bites. The characteristic response of cats to nepetalactol via the μ-opioid system provides an important example of chemical pest defense using plant metabolites in nonhuman mammals.https://www.science.org/doi/full/10.1126/sciadv.abd9135

10/21/2021 4:00 PMMysterious forces may be a reliable trope in science fiction, but in reality, physicists have long agreed that all interactions between objects evidently arise from just four fundamental forces. Yet that has not stopped them from ardently searching for an additional, as-yet-unknown fifth fundamental force. The discovery of such a force could potentially resolve some of the biggest open questions in physics today, from the nature of dark energy to the seemingly irreconcilable differences between quantum mechanics and general relativity. Now, a recent experiment carried out at the National Institute of Standards and Technology (NIST) is offering fresh hints about a fifth force’s possible character. An international collaboration of researchers used neutrons and a silicon crystal to set new limits on the strength of a potential fifth fundamental force at atomic scales. Published in Science in September, the study also includes measurements of the precise structure of both silicon crystals and neutrons themselves.https://www.scientificamerican.com/article/new-universal-force-tested-by-blasting-neutrons-through-crystal/

10/22/2021 2:00 PMAn international team of physicists led by researchers at Indiana University Bloomington has announced the world’s most precise measurement of the neutron’s lifetime.https://phys.org/news/2021-10-physicists-world-precise-neutron-lifetime.html
10/22/2021 4:00 PMIs there life on Venus? That might sound like an odd, even absurd, question, given the extremely hostile conditions on the planet’s surface. After all, on Venus, it’s hot enough to melt lead. But, as we were reminded last year with the discovery of phosphine, there’s still the potential for microbial life in Venus’ atmosphere. Although the clouds are very acidic, temperatures and pressures become Earth-like at mid-altitudes. Now, a new study announced by researchers at CalPolyPomona in California shows that Earth-like photosynthesis in Venus’ atmosphere is possible.https://earthsky.org/space/photosynthesis-in-venus-atmosphere-phototrophs-microbes/
10/22/2021 6:00 PMIt isn’t every day that scientists dig up a dinosaur jaw—or unearth the remains of fossilized insects. So paleontologists couldn’t believe their luck when, in 2010, they found the 75-million-year-old jawbone of a duck-billed hadrosaur in Dinosaur Provincial Park in Canada’s Alberta province, topped with a 7-centimeter-wide blob of amber containing traces of trees and sap-sucking aphids.https://www.science.org/content/article/remarkable-fossil-features-insect-trapped-amber-stuck-dinosaur-jaw
10/23/2021 8:00 AMA team of scientists recently discovered the age of over 50 footprints that were found in fossilized beach sediment near Trachilos, Crete in 2017. They are the oldest known pre-human footprints ever found, dating back more than six million years. The international team of researchers published their findings in Scientific Reports on October 11. Utilizing geophysical and micropaleontological methods to find the age of the footprints the scientists estimated them to be about 6.05 million years old.https://www.newsweek.com/over-50-fossilized-footprints-found-sand-dated-more-6-million-years-old-1638673
10/23/2021 10:00 AMEven though we call it home, the Milky Way remains rich with mysteries and surprises. Case in point: Astronomers recently noticed our galaxy has a broken arm.https://astronomy.com/news/2021/09/the-milky-way-has-a-broken-arm
10/23/2021 12:00 PMScientists just broke the record for the coldest temperature ever measured in a lab: They achieved the bone-chilling temperature of 38 trillionths of a degree above -273.15 Celsius by dropping magnetized gas 393 feet (120 meters) down a tower.https://www.livescience.com/coldest-temperature-ever
10/23/2021 2:00 PMA widely accepted theory of Native American origins coming from Japan has been attacked in a new scientific study, which shows that the genetics and skeletal biology “simply does not match-up”.https://phys.org/news/2021-10-popular-theory-native-american-debunked.html
10/23/2021 4:00 PMThe source of marble for a statue of Apollo on the Greek island of Delos has been a mystery to art historians and archaeologists for decades. The stone’s chemistry pointed geochemists to the southern end of the nearby island of Naxos, but no one thought there were ancient marble quarries there. A geoarchaeologist believes he found the source.https://phys.org/news/2021-10-tucked-away-marble-quarries-source-archaic.html
10/23/2021 6:00 PMIn October 2019, a high-energy neutrino slammed into Antarctica. The neutrino, which was remarkably hard to detect, piqued astronomers’ interest: what could generate such a powerful particle?https://phys.org/news/2021-10-black-hole-star-neutrino.html
10/24/2021 8:00 AMAstronomers have discovered the very first confirmed planetary system that resembles the expected fate of our solar system, when the Sun reaches the end of its life in about five billion years.https://phys.org/news/2021-10-crystal-ball-solar-future.html
10/24/2021 10:00 AMA team of researchers affiliated with several institutions in Germany and two in France has set a new record for the lowest temperature ever recorded in a lab setting—38 picokelvins. In their paper published in the journal Physics, the group describes their work with a time-domain matter-wave lens system. Vincenzo Tamma with the University of Portsmouth has published a Viewpoint article in the same journal issue discussing the work done by the team in Germany.https://phys.org/news/2021-10-coldest-temperature38-picokelvins.html
10/24/2021 12:00 PMLike tardigrades, Bdelloid rotifers can also survive drying, freezing, starving, and even low-oxygen conditions. Now, scientists report that they revived some of these rotifers after having been frozen in Siberian permafrost for at least 24,000 years.https://www.iflscience.com/plants-and-animals/microscopic-animal-brought-back-to-life-after-24000-years-frozen-in-siberian-permafrost/
10/24/2021 2:00 PMThe interior of the Earth is a mystery, especially at greater depths (> 660 km). Researchers only have seismic tomographic images of this region and, to interpret them, they need to calculate seismic (acoustic) velocities in minerals at high pressures and temperatures. With those calculations, they can create 3D velocity maps and figure out the mineralogy and temperature of the observed regions. When a phase transition occurs in a mineral, such as a crystal structure change under pressure, scientists observe a velocity change, usually a sharp seismic velocity discontinuity.https://phys.org/news/2021-10-quantum-phase-transition-global-scale.html
10/24/2021 4:00 PMIn February of 2013, skywatchers around the world turned their attention toward asteroid 2012 DA14, a cosmic rock about 150 feet (50 meters) in diameter that was going to fly closer to Earth than the spacecraft that bring us satellite TV.https://phys.org/news/2021-10-physicists-method-defending-earth-cosmic.html
10/24/2021 6:00 PMThe Australian-made space weather satellite CUAVA-1 was deployed into orbit from the International Space Station on Wednesday (Oct. 6). Launched to the space station in August aboard a SpaceX Falcon 9 rocket, a major focus of this shoebox-sized CubeSat is to study what radiation from the sun does to Earth’s atmosphere and electronic devices.https://www.space.com/forecasting-space-weather-is-hard-a-new-australian-satellite-may-help-make-it-easier
10/25/2021 8:00 AMWhen light interacts with matter, for example, when a laser beam hits a two-dimensional material like graphene, it can substantially change the behavior of the material. Depending on the form of interaction between light and matter, some chemical reactions appear differently, substances turn magnetic or ferroelectric or begin to conduct electricity without any losses. In particularly thrilling cases, an actual light source may not even be necessary because the mere possibility for light to exist, i.e., its quantum equivalent, the photons, can change the behavior of matter. Theoretical scientists try to describe and predict these fascinating phenomena because they could be crucial in the development of new quantum technologies.https://phys.org/news/2021-10-highly-quantum-light-matter-interactions.html
10/25/2021 10:00 AMA global collaboration, led by researchers from UNSW, has shown how liquid gallium can be used to help achieve the important goal of net zero carbon emissions. Engineers from UNSW have helped to discover a cheap new way to capture and convert CO2 greenhouse emissions using liquid metal.https://phys.org/news/2021-10-liquid-metal-proven-cheap-efficient.html
10/25/2021 12:00 PMMetasurfaces are nanoscale structures that interact with light. Today, most metasurfaces use monolith-like nanopillars to focus, shape and control light. The taller the nanopillar, the more time it takes for light to pass through the nanostructure, giving the metasurface more versatile control of each color of light. But very tall pillars tend to fall or cling together. What if, instead of building tall structures, you went the other way?https://phys.org/news/2021-10-holey-metalens-focuses-ultra-deep-holes.html
10/25/2021 2:00 PMQuantum technology typically employs qubits (quantum bits) consisting of, for example, single electrons, photons or atoms. A group of TU Delft researchers has now demonstrated the ability to teleport an arbitrary qubit state from a single photon onto an optomechanical device—consisting of a mechanical structure comprising billions of atoms. Their breakthrough research, now published in Nature Photonics, enables real-world applications such as quantum internet repeater nodes while also allowing quantum mechanics itself to be studied in new ways.https://phys.org/news/2021-10-quantum-teleportation-mechanical-motion-silicon.html
10/25/2021 4:00 PMScientists have known for a long time that magnetism is created by the spins of electrons lining up in certain ways. But about a decade ago, they discovered another astonishing layer of complexity in magnetic materials: Under the right conditions, these spins can form little vortexes or whirlpools that act like particles and move around independently of the atoms that spawned them.https://phys.org/news/2021-10-skyrmions-lot-common-glass-high-temperature.html
10/25/2021 6:00 PMThe first time Frédéric Santoul witnessed the voracious feeding habits of Europe’s largest freshwater fish, he was standing on a medieval bridge in Albi, a town in southern France. On a small island below, in the Tarn River, pigeons wandered about, oblivious to the group of wels catfish moving near the gravel bank. Suddenly a fish catapulted out of the water and onto land, snatching a pigeon in a flurry of feathers before heaving itself back into the river, bird in mouth.https://www.nationalgeographic.com/a
