1/1/2022 6:00 PMThe largest planet discovered to date, that astronomers are sure is a planet and has an accurately measured diameter, is HAT-P-67 b. This planet is a “hot Jupiter” — a gas giant similar to Jupiter or Saturn, but orbiting so close to its star that it takes only a few days (4.8 days in this case) for the planet to orbit once around its sun.https://astronomy.com/magazine/ask-astro/2018/11/the-largest-exoplanet
1/2/2022 8:00 AMNASA marked an impressive milestone when its Parker Solar Probe was the first ever to touch the sun and return earlier this year, and footage from its historic mission offers a stunning glimpse at the massive star’s upper atmosphere. The black-and-white timelapse shows a view from the probe as it hurls through a flurry of glowing bands and sparks that dart across the frame with celestial bodies panning in the background. These structures, known as coronal streamers, are part of the magnetic field surrounding the star—it doesn’t have a solid surface, meaning satellites like Parker come in contact with the fiery matter while flying through it. These sweeping plumes are often visible from Earth during solar eclipses.https://www.thisiscolossal.com/2021/12/nasa-probe-sun-timelapse/

1/12/2022 10:00 AMBy analyzing the acquisition-conservation tradeoff in root systems among different plants, ecologists have put forward the root economics spectrum (RES) hypothesis. Some plant species have finer and cost-effective absorptive roots that contribute to rapid nutrient uptake but have shorter lifespans, whereas others have thicker and less cost-effective absorptive roots marked by slower nutrient acquisition but longer lifespans. The RES hypothesis reflects the correlations among different root traits, which can facilitate the adaptation of plants to the local environment. The RES is one of the core issues in root ecology, but its adaptive role and genetic basis remains largely elusive.https://phys.org/news/2021-12-exploring-genetic-basis-root-economics.html

1/14/2022 6:00 PMAstronomers have managed to link the properties of the inner planets of our solar system with our cosmic history: with the emergence of ring structures in the swirling disk of gas and dust in which these planets were formed. The rings are associated with basic physical properties such as the transition from an outer region where ice can form where water can only exist as water vapor. The astronomers made use of a spread of simulation to explore different possibilities of inner planet evolution. Our solar system’s inner regions are a rare, but possible outcome of that evolution.https://phys.org/news/2021-12-cosmic-history-properties-mercury-venus.html

1/16/2022 4:00 PMWhy the sun’s corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A “hot” trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves travel at the same speed. In an experiment using the molten alkali metal rubidium and pulsed high magnetic fields, a team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a German national lab, has developed a laboratory model, and for the first time experimentally confirmed the theoretically predicted behavior of these plasma waves.https://phys.org/news/2022-01-liquid-metal-insight-mechanism-sun-corona.html

1/21/2022 2:00 PMOne of the characteristic features of modern cosmology is its description of how galaxies evolve: via a hierarchical process of colliding and merging with other systems. Nowhere in the universe do we have a clearer view of this buildup than in our own Milky Way. Currently one of our nearby neighbors, the Sagittarius dwarf galaxy, is being tidally disrupted (a dwarf galaxy has less than about 1% of the stellar mass of a normal spiral galaxy like the Milky Way, and often much less). Two other nearby dwarfs, the Large and Small Magellanic Clouds (with about 1% and 0.7% of the stellar mass of the Milky Way, respectively) are falling towards us. Meanwhile streams of globular clusters encircle the Galaxy, marking the effects of prior mergers. The record of even more ancient mergers can be extracted from the positions and motions of stars in the Milky Way’s stellar halo, the roughly spherical distribution of stars (about one hundred thousand light-years in diameter) older than about 10-12 billion years. Meanwhile Andromeda, our nearest large neighboring galaxy, is about ten times farther away than these dwarfs; a merger with it is expected in another five billion years.https://phys.org/news/2022-01-galaxy-major-collision.html
1/21/2022 4:00 PMIt’s much easier for scientists to see the messy aftermath of stellar explosions than to watch the prelude to the drama. But finally, astronomers managed to observe a red giant star just as it “went supernova,” as exploding stars are called. Using a telescope in Hawaii, a team of scientists gathered observations of a red supergiant star in summer 2020. Lo and behold, in September, that very same star died in a supernova dubbed (SN) 2020tlf — an explosion that team members called “one of the most intriguing” supernovas of its type.https://www.space.com/supernova-observations-what-happens-before-star-explodes

1/22/2022 8:00 AMA group of mysterious, ultradense structures just outside Earth’s core may be the remnants of an ancient interplanetary collision, new research suggests. These strange structures are known as ultralow-velocity zones (ULVZs), because seismic waves generated by earthquakes travel about 50% more slowly through these zones than through the surrounding mantle. That means the ULVZs are also much denser than the rest of the mantle, and possibly made of heavier elements.https://www.space.com/ulvz-giant-impact-hypothesis.html

1/24/2022 12:00 PMGalaxies like the Milky Way are thought to have been built through a series of mergers, drawing in smaller galaxies and clusters of stars and making these foreign stars their own. In some cases, the mergers were recent enough that we can still detect the formerly independent object as a cluster of stars orbiting the Milky Way together. But, as time goes on, interactions with the rest of the stars in the Milky Way will slowly disrupt any structures the cluster incorporates. So it’s a bit of a surprise that researchers found what appear to be the remains of a globular cluster composed of some of the oldest stars around. The finding is consistent with a “growth through merger” model of galaxy construction, but it raises questions about how the cluster stayed intact for as long as it did.https://arstechnica.com/science/2022/01/stars-from-ancient-cluster-found-in-the-milky-way/

1/27/2022 4:00 PMElectrons flowing through power lines and computers inevitably encounter resistance; when they do, they lose some of their energy, which dissipates as heat. That’s why laptops get hot after being used for too long and why the server farms that power the cloud require so much air conditioning to keep the machines from overheating. Likewise, any particles carrying energy tend to lose that energy when they flow in a typical environment. There are a few exceptions, which usually occur at very low temperatures when particles form pairs called quantum condensates. This leads to superconductivity, with vanishing electrical resistance, in some metals such as aluminum, and superfluidity in liquified helium, which can then flow without dissipation.https://phys.org/news/2022-01-tuning-bonds-paired-quantum-particles.html

2/9/2022 2:00 PMThe queen is the most powerful piece on the chessboard. Unlike any other (including the king), it can move any number of squares vertically, horizontally, or diagonally. Now consider this queen’s gambit: If you put eight of them on a standard board of eight squares by eight squares, how many ways could they be arranged so that none could attack the other? Turns out there are 92. But what if you place an even larger number of queens on a chessboard of the same relative size, say, 1,000 queens on a 1,000-by-1,000 square chessboard, or even a million queens on a similarly sized board?https://phys.org/news/2022-01-harvard-mathematician-year-old-chess-problem.html

2/14/2022 4:00 PMMagnetic fields are detected throughout the universe and widely participate in astrophysical dynamics. Various fundamental phenomena, including coronal mass ejections, solar flares, gamma-ray bursts and pulsar winds, are dominated by variations in magnetic fields. Although the mechanisms involved in the origin of magnetic fields in space are still uncertain, one of the widely accepted plausible scenarios is the turbulent dynamo, which amplifies weak magnetic fields. Recent numerical studies and experiments with long pulse laser-produced colliding plasma flows have demonstrated the capability of seed field amplification. Coupling strong magnetic fields and high-power lasers supports cutting-edge research in laboratory astrophysics and laser-driven charged particle accelerations. With moderate laser intensities and a relatively long pulse length, mega-gauss (MG) magnetic fields in plasmas at the edges of focal spots have been achieved. Numerical and theoretical studies predict a magnetic field strength of 100 MG, while state-of-the-art experimental results are about 10 MG.https://phys.org/news/2022-01-instant-turn-over-magnetism-gyro-motion.html

2/20/2022 8:00 AMTransport yourself 50,000 years into the past, and you’d see that the Australian landscape of the Late Pleistocene wasn’t all that different from today’s. Upon leaving your time machine, however, you might wonder if the waters brimmed with steroids.

2/20/2022 12:00 PMThe subject of this image is a group of three galaxies, collectively known as NGC 7764A. They were imaged by the NASA/ESA Hubble Space Telescope, using both its Advanced Camera for Surveys and Wide Field Camera 3. The two galaxies in the upper right of the image appear to be interacting with one another. The long trails of stars and gas extending from them give the impression that they have both just been struck at great speed, thrown into disarray by the bowling-ball-shaped galaxy to the lower left of the image. In reality, interactions between galaxies happen over very long time periods, and galaxies rarely collide head-on with one another. It is also unclear whether the galaxy to the lower left is interacting with the other two, although they are so relatively close in space that it seems possible that they are. By happy coincidence, the collective interaction between these galaxies has caused the two on the upper right to form a shape, which from our solar system’s perspective, resembles the starship known as the USS Enterprise from Star Trek!https://www.nasa.gov/image-feature/goddard/2022/hubble-spots-a-starship-shaped-galactic-pair

2/26/2022 10:00 AMA few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even believed that the Standard Model of particle physics would have to be changed. Physicists at the University of Bonn and the Technical University of Darmstadt have now developed a method that allows them to analyze the results of older and more recent experiments much more comprehensively than before. This also results in a smaller proton radius from the older data.

2/27/2022 4:00 PMStar formation in the Milky Way primarily occurs in long, dense filaments of gas and dust that stretch along the spiral arms. Dubbed “bones” because they delineate the galaxy’s densest skeletal spiral structures, these filaments are characterized by being at least fifty times longer than they are wide and having coherent internal motions along their lengths. While most of the key physical properties of these bones are known, what we know of their magnetic field properties is generally unconstrained. These fields can play a critical role either in supporting the gas and dust against gravitational collapse into new stars, or alternatively, in assisting the flow of mass along the bone into cores making new stars. #science #astronomy #milkyway #galaxyhttps://phys.org/news/2022-02-magnetic-field-milky-filamentary-bone.html

3/3/2022 12:00 PMAt the center of spiral galaxies—those near to us but also those billions of light-years away—there is a vast spherical region made up of dark matter particles. This region has two defining characteristics: a density that is constant out to a certain radius that amazingly expands over time, while the density decreases. This suggests the existence of a direct interaction between the elementary particles that make up the dark matter halo and those that make up ordinary matter—protons, electrons, neutrons, and photons. We anticipate that this hypothesis is in direct conflict with the current prevailing theory used to describe the universe—known as Lambda-Cold Dark Matter—which posits that particles of cold dark matter are inert and do not interact with any other particle except gravitationally.https://phys.org/news/2022-02-distant-galaxies-true-nature-dark.html

3/5/2022 8:00 AMIt takes a lot of force to cough a loogie up a nearly 4-meter-long neck, but that’s what one dinosaur had to do. Paleontologists have found strange nodules on the neck of a 150-million-year-old sauropod, evidence of the first known respiratory infection in a dinosaur, The Guardian reports. The long-necked dinosaur, nicknamed Dolly, lived during the late Jurassic period and was unearthed in Montana more than 30 years ago. When researchers recently re-examined the skeleton, they found strange broccoli-shaped bone clusters near where the animal’s air sacs would have been. They looked just like similar spurs that spring up in birds’ lungs when they get a respiratory infection, and computerized tomography scans confirmed the idea, the researchers write this week in Scientific Reports. The team thinks the infection was similar to aspergillosis, which is caused by inhaling mold and can be fatal to modern birds. Although they don’t know whether the infection killed Dolly, it’s clear the poor dino would have been feverish, coughing, and sniffling, they say.https://www.science.org/content/article/sick-dinosaur-may-have-had-earliest-known-cough

3/18/2022 10:00 AMApproximately 80 miles from the westernmost reach of China’s Great Wall, paleontologists found relics of an even more ancient world. Over the last two decades, teams of researchers unearthed more than 100 specimens of fossil birds that lived approximately 120 million years ago, during the time of the dinosaurs. However, many of these fossils have proved difficult to identify: they’re incomplete and sometimes badly crushed. In a new paper, researchers examined six of these fossils and identified two new species. And as a fun side note, one of those new species had a movable bony appendage at the tip of its lower jaw that may have helped the bird root for food.https://phys.org/news/2022-02-fossil-birds-china-great-wall.html
3/18/2022 12:00 PMBrown dwarfs are strange celestial bodies, occupying a kind of intermediate position between stars and planets. Astrophysicists sometimes call them “failed stars” because they have insufficient mass to burn hydrogen in their cores and shine like stars. It is continually debated if the formation of brown dwarfs is simply a scaled-down version of the formation of Sun-like stars. Astrophysicists are focusing on the youngest brown dwarfs, also called proto-brown dwarfs. They are only a few thousand years old and are still in the early formation stages. They want to know if the gas and dust in these proto-brown dwarfs resemble the composition of the youngest Sun-like proto-stars.https://phys.org/news/2022-02-insights-formation-brown-dwarfs.html

3/21/2022 12:00 PMExploding a photo subject in order to take its picture? An international research team at the European XFEL, the world’s largest X-ray laser, applied this “extreme” method to take pictures of complex molecules. The scientists used the ultra-bright X-ray flashes generated by the facility to take snapshots of gas-phase iodopyridine molecules at atomic resolution. The X-ray laser caused the molecules to explode, and the image was reconstructed from the pieces. “Thanks to the European XFEL’s extremely intense and particularly short X-ray pulses, we were able to produce an image of unprecedented clarity for this method and the size of the molecule,” reports Rebecca Boll from the European XFEL, principal investigator of the experiment and one of the two first authors of the publication in the scientific journal Nature Physics in which the team describes their results. Such clear images of complex molecules have not been possible using this experimental technique until now.https://phys.org/news/2022-02-molecule-snapshot-explosion.html

3/21/2022 6:00 PMIf a star is gigantic enough, it can collapse in on itself to form a black hole. Stars that are still huge, but not big enough to become black holes, tend to explode in supernovae, eventually transforming into what is known as a neutron star. What has long puzzled scientists is that the smallest black holes tend to be at least five times the mass of the Sun, while neutron stars are at most 2.5 times the mass of the Sun. Inside those boundaries lies what has become known as the “mass gap” — a mysterious range between the mass of black holes and neutron stars. Now, though, a new discovery by a team of European astronomers seems to fit into that gap, suggesting a new class of objects that were thought to be impossible.https://futurism.com/astronomers-may-have-discovered-first-ever-black-neutron-star

3/23/2022 8:00 AMThe third-largest crater on the dwarf planet Ceres was geologically active at least once many millions of years after its formation. In a recent study published today in the journal Nature Communications, researchers from the Max Planck Institute for Solar System Research (MPS) in Göttingen, the University of Münster (WWU) and the National Institute of Science Education and Research (NISER) in Bhubaneswar, India present the most detailed study of Urvara crater to date. For the first time, they evaluated camera images from the last phase of NASA’s Dawn mission, which reveal geological structures only a few meters in size. The Dawn spacecraft entered orbit around the dwarf planet in 2015 and studied it up close for about three and a half years. Like Occator crater, Urvara crater may have been the scene of cryovolcanic activity, the researchers argue. The study supports the picture that a global saline ocean extended beneath Ceres’ crust, some of which may still be liquid today.https://phys.org/news/2022-02-dwarf-planet-ceres-chemistry-salt.html

3/24/2022 4:00 PMScientists from University of Regensburg, Massachusetts Institute of Technology, Moscow institute of Physics and Technology, and University of Kansas have discovered abnormally strong light absorption in graphene. The effect arises from the conversion of ordinary electromagnetic waves into super-slow surface waves running through graphene. The observation is of fundamental interest and shows in an impressive way how the interaction of Bernstein modes, collective excitations of electrons driven by their cyclotron motion and the smearing of electric fields at the smallest scales due to nonlocality can influence the radiation absorption of graphene. This behavior could serve as the basis for extremely sensitive infrared and terahertz detectors much smaller than existing ones, with similar absorption efficiency.https://phys.org/news/2022-02-abnormally-strong-absorption-graphene.html

3/26/2022 12:00 PMWhen it comes to describing the fundamental structure and composition of matter, the research field of quantum chromodynamics (QCD) comes into play. With the help of QCD, the strong interaction—one of the four fundamental forces of physics—between the elementary particles of quarks and gluons can be described in hadrons. Hadrons are subatomic particles held together by the strong interaction. The best-known examples are neutrons and protons (so-called baryons), and the lesser-known pion (a so-called meson) is also a hadron. “To a first approximation, the pions are the driving particles behind the strong interaction,” says the physicist Urs Wenger, professor at the Institute for Theoretical Physics at the University of Bern.https://phys.org/news/2022-02-simulate-important-elements-pion.html

3/29/2022 8:00 AMA huge amount of mysterious dark energy is necessary to explain cosmological phenomena, such as the accelerated expansion of the Universe, using Einstein’s theory. But what if dark energy was just an illusion and general relativity itself had to be modified? A new SISSA study, published in Physical Review Letters, offers a new approach to answer this question. Thanks to huge computational and mathematical effort, scientists produced the first simulation ever of merging binary neutron stars in theories beyond general relativity that reproduce a dark-energy like behavior on cosmological scales.

4/9/2022 2:00 PMOn most days, the Earth Observatory presents our planet in close-up, filling the camera with its oceans and mountain ranges, clouds and rivers. But occasionally, NASA helps us all take a step back to see the big picture of our place in the solar system and universe. Such a view was recently beamed back by NASA’s Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft.https://earthobservatory.nasa.gov/images/45710/earth-and-moon-from-mercury
4/9/2022 4:00 PMSoft and immobile, sea sponges may appear inert, but these simple animals are rich with chemistry. From them, scientists have uncovered plenty of biologically active compounds, some of which have gone on to become medications. All of these small molecules, however, actually originate from bacteria living within these animals. Now, new research has uncovered an exception. Today, scientists report that sponges themselves, not their resident microbes, produce at least one promising group of compounds.https://phys.org/news/2022-03-sponges-microbes-biologically-potent-compounds.html

4/10/2022 4:00 PMMost living organisms have an internal clock which, among other things, controls the sleep-wake rhythm. The internal rhythm lasts approximately one day (circadian), i.e. about 24 hours, and is regulated by means of various clock genes. There is also permanent coordination with factors such as light and temperature for synchronizing the internal clock with the external day-night rhythm. A team led by neurobiologist Prof. Ralf Stanewsky from the University of Münster has now demonstrated in the Drosophila melanogaster fruit fly that a certain ion transport protein (KCC) plays a role in regulating circadian rhythms by means of light.https://phys.org/news/2022-03-internal-clock-fruit.html

4/12/2022 8:00 AMFirst predicted in Einstein’s theory of general relativity, gravitational waves are tiny ripples in spacetime generated by titanic and powerful cosmic events. The great physicist believed that no equipment would ever be sensitive to detect these faint cosmic ripples. Fortunately, Einstein was wrong, but that doesn’t mean that the detection of gravitational waves has been easy.https://phys.org/news/2022-03-documents-gravitational-wave-observatory-europe.html

4/12/2022 12:00 PMEver feel like there’s just not enough time in the day? Turns out, you might be onto something. Earth is rotating faster than it has in the last half-century, resulting in our days being ever-so-slightly shorter than we’re used to. And while it’s an infinitesimally small difference, it’s become a big headache for physicists, computer programmers and even stockbrokers.https://astronomy.com/news/2022/02/earth-is-spinning-faster-now-than-it-was-50-years-ago

4/12/2022 4:00 PMComputers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There is one obstacle, however: after a few hundred kilometers within an optical fiber, the photons that carry the qubits or “quantum bits” (the information) disappear. They therefore need “repeaters,” a kind of “relay,” which are partly based on a quantum memory. By managing to store a qubit in a crystal (a “memory”) for 20 milliseconds, a team from the University of Geneva (UNIGE) has set a world record and taken a major step towards the development of long-distance quantum telecommunications networks.https://phys.org/news/2022-03-quantum-bit-fora-record-breaking-milliseconds.html
4/12/2022 6:00 PMBlack holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers.

4/13/2022 10:00 AMNASA is preparing to send humans to Mars sometime in the 2030s. The 3-year mission will expose astronauts to a long period of microgravity, which will cause them to lose bone mass. But now, scientists report transgenic lettuce that produces a bone-stimulating hormone. Someday, astronauts could grow the lettuce in space and help guard against bone loss—simply by eating a big bowl of salad. In addition, the lettuce might help stave off osteoporosis in resource-limited areas here on Earth, the researchers say.https://phys.org/news/2022-03-space-grown-lettuce-astronauts-bone-loss.html

4/14/2022 8:00 AMScientists have found a new way to “see” inside the simplest atomic nuclei to better understand the “glue” that holds the building blocks of matter together. The results, just published in Physical Review Letters, come from collisions of photons (particles of light) with deuterons, the simplest atomic nuclei (made of just one proton bound to one neutron).https://phys.org/news/2022-03-physicists-breakup-simple-nucleus.html
4/14/2022 10:00 AMThe double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and particle characteristics — known as the particle-wave duality of matter — depending on the scenario, according to the scientific communication site Interesting Engineering. According to the University of Sussex, American physicist Richard Feynman referred to this paradox as the central mystery of quantum mechanics.https://www.space.com/double-slit-experiment-light-wave-or-particle
4/14/2022 12:00 PMThe number of sunspots on our sun typically ebbs and flows in a predictable 11-year cycle, but one unusual 70-year period when sunspots were incredibly rare has mystified scientists for 300 years. Now, a nearby sun-like star seems to have paused its own cycles and entered a similar period of rare starspots, according to a team of researchers at Penn State. Continuing to observe this star could help explain what happened to our own sun during this “Maunder minimum” as well as lend insight into the sun’s stellar magnetic activity, which can interfere with satellites and global communications and possibly even affect climate on Earth.https://phys.org/news/2022-03-nearby-star-sun-didnt-sunspots.html

4/16/2022 6:00 PMSilicon solar cells have proven to be a top photovoltaic technology, as they use earth abundant raw materials (i.e. Si) and perform with high efficiency. However, they are based on thick, rigid and heavy wafers and can therefore only be installed in a limited number of places. One of the ways to overcome this disadvantage is to use thin membranes instead. This will reduce the amount of Si by more than 99% (dramatically saving in raw materials) and also make the cells flexible and lightweight. As such, these cells can be easily integrated into buildings, urban architecture and even small everyday gadgets. The problem is that such thin Si membranes cannot absorb light as efficiently. In fact, only 25% of the sunlight is absorbed and you can even see through them.https://phys.org/news/2022-03-efficiencies-thin-photovoltaic-cells.html

4/17/2022 12:00 PMPhysicists know about the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and to describe the behavior of complex quantum many-body systems, for example black holes and wormholes in the universe. Now, a theory group at Freie Universität Berlin and Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), together with Harvard University, U.S., has proven a mathematical conjecture about the behavior of complexity in such systems, increasing the viability of this bridge.https://phys.org/news/2022-03-group-quantum-complexity-linearly-exponentially.html

Researchers have devised a better way to visualize molecules building on these traditional methods. Their models fit the imaging data they acquire well, and they hope the models can therefore help chemists with their intuition for interpreting molecular images.https://phys.org/news/2022-03-visualizing-invisible-aid-atomic-resolution.html

4/21/2022 6:00 PMNewton’s theory of gravity stated that gravity acted at a distance and instantaneously. Einstein showed that not to be the case. His general theory of relativity exorcised Newton’s mysterious action at a distance by having gravity traveling at the speed of light and acting locally in a curved space. To Einstein’s horror, quantum physics boasts a very “spooky action at a distance,” (his term) that he couldn’t exorcise. Current experiments have confirmed that nature is even spookier than Einstein ever would have accepted.https://bigthink.com/13-8/einstein-spooky-action-at-a-distance/

5/4/2022 4:00 PMA new and surprising duality has been discovered in theoretical particle physics. The duality exists between two types of scattering processes that can occur in the proton collisions made in the Large Hadron Collider at CERN in Switzerland and France. The fact that this connection can, surprisingly, be made points to the fact that there is something in the intricate details of the standard model of particle physics that is not fully understood. The standard model is the model of the world on sub-atomic scale that explains all particles and their interactions, so when surprises appear, there is cause for attention.https://phys.org/news/2022-04-duality-theoretical-particle-physics.html

5/16/2022 8:00 AMAs a result of corrosion, copper and silver release positively charged ions into their environment, which are harmful to bacteria in several ways and prevent their growth or kill them completely. This effect has long been exploited, for example by coating implants with these metals to prevent bacterial infections. There are some tricks that can be employed to release even more ions and intensify this effect. For example, the team headed by materials researcher Professor Alfred Ludwig uses a so-called sputtering system with which the thinnest layers or tiny nanopatches of the metals can be applied to a carrier material. Depending on the sequence or quantity in which the individual metals are applied, different surface textures are created. If a precious metal such as platinum is also applied, silver corrodes even faster and releases more antibacterial ions.https://phys.org/news/2022-05-copper-silver-effective-sars-cov-surfaces.html

5/16/2022 6:00 PMSomething strange is afoot in the galaxy known as 1ES 1927+654: In late 2017, and for reasons that scientists couldn’t explain, the supermassive black hole sitting at the heart of this galaxy underwent a massive identity crisis. Over a span of months, the already-bright object, which is so luminous that it belongs to a class of black holes known as active galactic nuclei (AGN), suddenly grew a lot brighter—glowing nearly 100 times more than normal in visible light.https://phys.org/news/2022-05-surging-distant-galaxy-black-holes.html
5/17/2022 8:00 AMSince 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C. Now a new sonification brings more notes to this black hole sound machine. This new sonification – that is, the translation of astronomical data into sound – is being released for NASA’s Black Hole Week this year.https://www.nasa.gov/mission_pages/chandra/news/new-nasa-black-hole-sonifications-with-a-remix.html

5/27/2022 2:00 PMThe behavior of microscopic quantum magnets has long been a subject taught in lectures in theoretical physics. However, investigating the dynamics of systems that are far out of equilibrium and watching them “live” has been difficult so far. Now, researchers at the Max Planck Institute of Quantum Optics in Garching have accomplished precisely this, using a quantum gas microscope. With this tool, quantum systems can be manipulated and then imaged with such high resolution that even individual atoms are visible. The results of the experiments on linear chains of spins show that the way their orientation propagates corresponds to the so-called Kardar-Parisi-Zhang superdiffusion. This confirms a conjecture that recently emerged from theoretical considerations.https://phys.org/news/2022-05-quantum-magnets-motion.html

6/25/2022 10:00 AMDue to high hole mobility, pentacene and its derivatives have been the representative organic semiconductor and have been the subject of much research, both basic and applied. In particular, they are expected to be applied to semiconductor devices, such as field-effect transistors. In addition, organic semiconductors have the advantage of being inexpensive to produce through inkjet printing, and they have low environmental impacts because they do not use metals. However, the backbone of organic semiconductors, such as pentacene, easily reacts with oxygen molecules under visible light, resulting in the loss of useful properties.https://phys.org/news/2022-06-pentacene-derivative-durability-conventional-products.html

6/26/2022 8:00 AMIf mechanoluminescent materials are subjected to external mechanical stress, they emit visible or invisible light. Such excitation can occur due to bending or gentle pressure, for example, but also completely contact-free through ultrasound. In this way, the effect can be triggered remotely and light can be brought to places that normally tend to be in the dark, for example in the human body. If the ultrasound treatment is to be used at the same time to generate local heat, it is important in such a sensitive environment to observe closely the temperatures that occur. Material scientists at Friedrich Schiller University Jena, Germany have now developed a mechanoluminescent material that can not only be used to generate a local heat input by means of ultrasound, but also provides feedback on the local temperature at the same time.https://phys.org/news/2022-06-emission-temperature-ultrasound.html

7/9/2022 12:00 PMUsing new analyses, scientists have just found the last two of the five informational units of DNA and RNA that had yet to be discovered in samples from meteorites. While it is unlikely that DNA could be formed in a meteorite, this discovery demonstrates that these genetic parts are available for delivery and could have contributed to the development of the instructional molecules on early Earth. The discovery, by an international team with NASA researchers, gives more evidence that chemical reactions in asteroids can make some of life’s ingredients, which could have been delivered to ancient Earth by meteorite impacts or perhaps the infall of dust.https://www.nasa.gov/feature/goddard/2022/life-blueprint-in-asteroids
7/9/2022 2:00 PMWhen is a thumb not a thumb? When it’s an elongated wrist bone of the giant panda used to grasp bamboo. Through its long evolutionary history, the panda’s hand has never developed a truly opposable thumb and instead evolved a thumb-like digit from a wrist bone, the radial sesamoid. This unique adaptation helps these bears subsist entirely on bamboo despite being bears (members of the order Carnivora, or meat-eaters). In a new paper published in Scientific Reports, the Natural History Museum of Los Angeles County’s Curator of Vertebrate Paleontology Xiaoming Wang and colleagues report on the discovery of the earliest bamboo-eating ancestral panda to have this “thumb.” Surprisingly, it’s longer than its modern descendants.https://phys.org/news/2022-06-pandas-gave-bamboo-thumbs-million.html

7/10/2022 8:00 AMBlack holes and galaxies have a complicated relationship. Astronomers think nearly every galaxy hosts a giant black hole in its core. And while those black holes truly are massive — weighing millions, or even billions, of solar masses — they are tiny compared with their home galaxies, reaching less than 1% of the mass of a typical galaxy and a volume a billion times smaller. Despite the huge discrepancy, these massive black holes are capable of exerting an outsize influence, controlling the rate of star formation for billions of years.https://www.space.com/black-holes-and-galaxies-relationship

7/15/2022 8:00 AMIf you switch a bit in the memory of a computer and then switch it back again, you have restored the original state. There are only two states that can be called “0 and 1.” However, an amazing effect has now been discovered at TU Wien (Vienna): In a crystal based on oxides of gadolinium and manganese, an atomic switch was found that has to be switched back and forth not just once, but twice, until the original state is reached again. During this double switching-on and switching-off process, the spin of gadolinium atoms performs one full rotation.

7/21/2022 2:00 PMAlthough you’ll probably never see them, you can spot them by the tell-tale mounds of sandy soil dotting a field: pocket gophers. Beneath your feet, the gophers continuously create and remold a labyrinth of winding tunnels hundreds of feet long. And, perhaps, tend the world’s most recently discovered farms. Root farms, that is.https://phys.org/news/2022-07-root-farming-gophers-closest-agricultural-relatives.html
7/21/2022 4:00 PMUsing multiple radio telescopes across the world, a team of astronomers from the Cosmic Dawn Center, Copenhagen, have discovered several galaxies in the early universe that, due to massive amounts of dust, were hidden from our sight. The observations allowed the team to measure the temperature and thickness of the dust, demonstrating that this type of galaxies contributed significantly to the total star formation when the universe was only 1/10 of its current age.https://phys.org/news/2022-07-radio-microwaves-reveal-true-nature.html
7/21/2022 6:00 PMIn 2019, astronomers observed the nearest example to date of a star that was shredded, or “spaghettified,” after approaching too close to a massive black hole. That tidal disruption of a sun-like star by a black hole 1 million times more massive than itself took place 215 million light years from Earth. Luckily, this was the first such event bright enough that astronomers from the University of California, Berkeley, could study the optical light from the stellar death, specifically the light’s polarization, to learn more about what happened after the star was torn apart.https://phys.org/news/2022-07-ultimate-fate-star-shredded-black.html

8/22/2022 8:00 AMThe graphite-diamond phase transition is of particular interest for fundamental reasons and a wide range of applications. On very fast compression time scales, material kinetics hinder the transition from graphite to the equilibrium cubic diamond crystal structure that we commonly know as diamond. Shock wave compression of graphite typically requires pressures above 50 GPa (500,000 atmospheres) to observe the phase transition on the time scale of shock compression experiments. Further, the hexagonal polytype of diamond called Lonsdaleite has been observed in shock compressed material subsequent to meteorite impact events, suggesting that the time scale of compression plays a strong role in the phase transition.https://phys.org/news/2022-08-graphite-hexagonal-diamond-picoseconds.html

The evidence is suppression of back-to-back pairs of particles emerging from collisions between protons and heavier ions (the nuclei of atoms), as tracked by RHIC’s STAR detector. In a paper just published in Physical Review Letters, the STAR collaboration shows that the bigger the nucleus the proton collides with, the larger the suppression in this key signature, as predicted by theoretical models of gluon saturation.https://phys.org/news/2022-08-saturation-emerge-particle-collisions-rhic.html

Then, among myriads of randomly self-assembled chemical structures, one tiny RNA molecular machine reveals itself as perfectly suitable for creating bonds between activated amino acids, the building blocks of future proteins.https://phys.org/news/2022-09-life-rna-pocket.html
9/23/2022 4:00 PMThere are all sorts of conservation laws in the Universe: for energy, momentum, charge, and more. Many properties of all physical systems are conserved: where things cannot be created or destroyed. We’ve learned how to create matter under specific, explicit conditions: by colliding two quanta together at high enough energies so that equal amounts of matter and antimatter can emerge, so long as E = mc² allows it to happen. For the first time, we’ve managed to create particles without any collisions or precursor particles at all: through strong electromagnetic fields and the Schwinger effect. Here’s how.https://bigthink.com/starts-with-a-bang/something-from-nothing/
9/23/2022 6:00 PMAstronomers agree that planets are born in protoplanetary disks—rings of dust and gas that surround young, newborn stars.

10/5/2022 8:00 AMBlack holes are cosmic vacuum cleaners — massive objects so large that not even light can escape them. Most people imagine black holes do nothing but sit there and devour wandering pieces of gas or dust. But could black holes actually have more interesting interior lives? Could they, for instance, explode? If an “explosion” is “a sudden, brief release of tremendous amounts of energy” then the answer is unequivocally yes. And the best part is that they can explode in several interesting ways, either by detonating themselves or their nearby environments.https://www.space.com/can-a-black-hole-explode

10/15/2022 6:00 PMOne of the more unsettling discoveries in the past half century is that the universe is not locally real. “Real,” meaning that objects have definite properties independent of observation—an apple can be red even when no one is looking; “local” means objects can only be influenced by their surroundings, and that any influence cannot travel faster than light. Investigations at the frontiers of quantum physics have found that these things cannot both be true. Instead, the evidence shows objects are not influenced solely by their surroundings and they may also lack definite properties prior to measurement. As Albert Einstein famously bemoaned to a friend, “Do you really believe the moon is not there when you are not looking at it?”https://www.scientificamerican.com/article/the-universe-is-not-locally-real-and-the-physics-nobel-prize-winners-proved-it/

10/22/2022 2:00 PMFrom experience, driving through the city center takes longer than covering the same distance on an open country road. After all, you will encounter a lot of other road users, red lights, road works and traffic jams in the city center. Conversely, if you want to find out how busy a road is without having to join the traffic, you can measure the time it takes cars to travel a certain distance. This is precisely how traffic obstructions are identified by modern navigation systems. In the microcosm, this concept is maintained. When electrons (the smallest possible charge carriers) move through solids, they can interact with other electrons, changing their dynamics. However, due to the tiny mass of the electrons, the relevant processes take place unimaginably fast and they follow the intriguing laws of quantum physics rather than classical mechanics.https://phys.org/news/2022-10-crystalline-attoclock-ultrafast-motion-free.html

10/29/2022 2:00 PMIt’s impossible to hide from a female mosquito—she will hunt down any member of the human species by tracking our CO2 exhalations, body heat, and body odor. But some of us are distinct “mosquito magnets” who get more than our fair share of bites. Blood type, blood sugar level, consuming garlic or bananas, being a woman, and being a child are all popular theories for why someone might be a preferred snack. Yet for most of them, there is little credible data, says Leslie Vosshall, head of Rockefeller’s Laboratory of Neurogenetics and Behavior.https://phys.org/news/2022-10-mosquito-magnet.html?fbclid=IwAR3Xt9-FhwBYEHkRwi0tZ-KoAQ_6blnOhodIfYMobG5eKhzpv0DcG4Ie_sY

10/30/2022 2:00 PMHigh up in a tree sits a bright red vermilion flycatcher. The males of this songbird species use their red feathers to attract females. Meanwhile, an Arizona mountain kingsnake slithers among the rocks below. Its vivid red, yellow and black coloring mimics that of the venomous coral snake to keep predators away. But why did these two species evolve similar colors to send completely different messages?https://phys.org/news/2022-10-bright-animal-kingdom-intimidate.html?fbclid=IwAR3h96dFXEyHCUyhrXYw-hsE1K3vKX6e35AovOBvF-pWMqYsE7CrepYnosU
10/30/2022 4:00 PMIn quantum physics, Fermi’s golden rule, also known as the golden rule of time-dependent perturbation theory, is a formula that can be used to calculate the rate at which an initial quantum state transitions into a final state, which is composed of a continuum of states (a so-called “bath”). This valuable equation has been applied to numerous physics problems, particularly those for which it is important to consider how systems respond to imposed perturbations and settle into stationary states over time.https://phys.org/news/2022-10-exploring-quantum-state-weakly-coupled.html?fbclid=IwAR0kv5MCxOlGiPjtAj4fzx-LkHwCqXk0hZbReYTdhw41oAZttYSbskqM_-Q
