6/30/2019 10:00 AMSupermassive black holes exist at the center of most galaxies, and our Milky Way is no exception. But many other galaxies have highly active black holes, meaning a lot of material is falling into them, emitting high-energy radiation in this “feeding” process. The Milky Way’s central black hole, on the other hand, is relatively quiet. New observations from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, are helping scientists understand the differences between active and quiet black holes.https://phys.org/news/2019-06-magnetic-field-milky-black-hole.html

7/3/2019 2:00 PMA long life and lots of children—that was quite a common aspiration until not so long ago. But the world of animals reveals that high fertility and longevity are often mutually exclusive: Particularly animals with shorter lifespans are often very fertile while animals that live longer frequently produce fewer offspring. It seems that organisms with limited resources can be either long-lived or very fertile—but they can’t be both at the same time. Scientists at the Max Planck Institute for Evolutionary Biology in Plön have now discovered how the trade-off between survival and fertility works. They have found that the average age at reproduction is a measure for the loss of fertility as life expectancy increases.https://phys.org/news/2019-06-longer-children.html

7/4/2019 8:00 AMMost people think of water as existing in only one of three phases: Solid ice, liquid water, or gas vapor. But matter can exist in many different phases—ice, for example, has more than ten known phases, or ways that its atoms can be spatially arranged. The widespread use of piezoelectric materials, such as microphones and ultrasound, is possible thanks to a fundamental understanding of how an external force, like pressure, temperature, or electricity, can lead to phase transitions that imbue materials with new properties.https://phys.org/news/2019-06-revealing-hidden-phases-power.html

8/18/2019 12:00 PMBetween 10 million and 6 million years ago, vegetation across much of the world underwent a transformation, as warmth-adapted grasses displaced previously dominant plants, shrubs and trees. The new grasses carried out the chemical reactions required for photosynthesis in a distinct new way. Scientists have labeled this new process the C4 pathway. In East Africa, the changeover coincided with the evolution of mammal lineages that we recognize today, including early human ancestors. Today, C4 plants comprise about one-quarter of the Earth’s vegetation, from the Great Plains of North America to western China, Australia and much of sub-Saharan Africa.https://phys.org/news/2019-07-africa-grasslands.html

8/19/2019 6:00 PMMany people have a clear picture of the “Little Ice Age” (from approx. 1300 to 1850). It’s characterized by paintings showing people skating on Dutch canals and glaciers advancing far into the alpine valleys. That it was extraordinarily cool in Europe for several centuries is proven by a large number of temperature reconstructions using tree rings, for example, not just by historical paintings. As there are also similar reconstructions for North America, it was assumed that the “Little Ice Age” and the similarly famous “Medieval Warm Period” (approx. 700—1400) were global phenomena. But now an international group led by Raphael Neukom of the Oeschger Center for Climate Change Research at the University of Bern is painting a very different picture of these alleged global climate fluctuations.https://phys.org/news/2019-07-20th-century-unmatched-years.html

9/24/2019 4:00 PMFuture warming can accelerate the disintegration of the West Antarctic ice sheet. A large fraction of the ice will enter the Southern Ocean in form of icebergs, which melt and provide a cooling and freshening effect to the warmer and denser ocean water. This process will increase the formation of sea-ice and shift winds and ocean currents. The overall effect is a slowdown in the magnitude of human-induced Southern Hemispheric warming and sea-level rise, according to a new study.https://www.sciencedaily.com/releases/2019/08/190812172328.htm

9/28/2019 12:00 PMOne of the greatest mysteries in condensed matter physics is the exact relationship between charge order and superconductivity in cuprate superconductors. In superconductors, electrons move freely through the material—there is zero resistance when it’s cooled below its critical temperature. However, the cuprates simultaneously exhibit superconductivity and charge order in patterns of alternating stripes. This is paradoxical in that charge order describes areas of confined electrons. How can superconductivity and charge order coexist?https://phys.org/news/2019-08-unraveling-stripe-mystery.html
9/28/2019 2:00 PMScientists have found how to relieve a bottleneck in the process by which plants transform sunlight into food, which may lead to an increase in crop production.

10/1/2019 6:00 PMCrude oil and gas naturally escape from the seabed in many places known as “seeps.” There, these hydrocarbons move up from source rocks through fractures and sediments toward the surface, where they leak out of the ground and sustain a diversity of densely populated habitats in the dark ocean. Alkanes are already degraded before they reach the sediment surface. Even deep down in the sediment, where no oxygen exists, it provides an important energy source for subsurface microorganisms, amongst them some of the so-called archaea.https://phys.org/news/2019-08-all-in-one-microbe-degrades-oil-gas.html

10/21/2019 10:00 AMIn 2019 paleontologists Fabio Marco Dalla Vecchia named and described a new pterosaur, Seazzadactylus venieri. It’s known from a single, mostly complete semiarticulated specimen on a single block of stone that was found as a boulder in the middle of the Seazza Brook near the town of Preone, in northeastern Italy. The lithology of the boulder indicates that it came from the Upper Triassic Dolomia di Forni Formation. The skeleton was first discovered in the 1990s by Umberto Venier, and provisionally considered a specimen of Eudimorphodon, but wasn’t fully described until Dalla Vecchia’s 2019 publication. The genus and species names honor Seazza Brook and its discoverer.https://www.pteros.com/pterosaurs/seazzadactylus.html

11/20/2019 6:00 PMResearchers using telescopes around the world confirmed and characterized an exoplanet orbiting a nearby star through a rare phenomenon known as gravitational microlensing. The exoplanet has a mass similar to Neptune, but it orbits a star lighter (cooler) than the Sun at an orbital radius similar to Earth’s orbital radius. Around cool stars, this orbital region is thought to be the birth place of gas-giant planets. The results of this research suggest that Neptune-sized planets could be common around this orbital region. Because the exoplanet discovered this time is closer than other exoplanets discovered by the same method, it is a good target for follow-up observations by world-class telescopes like the Subaru Telescope.https://phys.org/news/2019-11-worldwide-nearby-lensing-exoplanet.html

12/4/2019 4:00 PMCRISPR-based tools have revolutionized our ability to target disease-linked genetic mutations. CRISPR technology comprises a growing family of tools that can manipulate genes and their expression, including by targeting DNA with the enzymes Cas9 and Cas12 and targeting RNA with the enzyme Cas13. This collection offers different strategies for tackling mutations. Targeting disease-linked mutations in RNA, which is relatively short-lived, would avoid making permanent changes to the genome. In addition, some cell types, such as neurons, are difficult to edit using CRISPR/Cas9-mediated editing, and new strategies are needed to treat devastating diseases that affect the brain.https://phys.org/news/2019-07-crispr-platform-rna-capabilities.html

12/7/2019 8:00 AMA particular kind of elementary particle, the Weyl fermions, were first discovered a few years ago. Their specialty: they move through a material in a well ordered manner that practically never lets them collide with each other and is thus very energy efficient. This opens up intriguing possibilities for the electronics of the future. Up to now, Weyl fermions had only been found in certain non-magnetic materials. Now however, for the very first time, scientists at the Paul Scherrer Institute PSI have experimentally proved their existence in another type of material: a paramagnet with intrinsic slow magnetic fluctuations. This finding also shows that it is possible to manipulate the Weyl fermions with small magnetic fields, potentially enabling their use in spintronics, a promising development in electronics for novel computer technology.

12/18/2019 2:00 PMWith between 20,000 and 2 million species, diatoms are one of the largest and most important ecological groups of organisms. Through photosynthesis, it’s been estimated that these single-cell algae produce up to one-quarter of the Earth’s oxygen. In addition to their important role within the ecosystem, diatoms also possess uniquely beautiful cell structures. During the Victorian era, this beauty inspired artists to position the jewel-like cells into dazzling arrangements under the lens of the microscope. This unusual art form was almost lost with time, but was recently revived by modern-day microscopist Klaus Kemp. Struck by the beauty and symmetry of diatoms, Kemp worked obsessively for 8 years to perfect his own technique.https://www.nationalgeographic.com/video/shorts/869435459875/

12/22/2019 10:00 AMIn 2015, David Hole was prospecting in Maryborough Regional Park near Melbourne, Australia. Armed with a metal detector, he discovered something out of the ordinary – a very heavy, reddish rock resting in some yellow clay. He took it home and tried everything to open it, sure that there was a gold nugget inside the rock – after all, Maryborough is in the Goldfields region, where the Australian gold rush peaked in the 19th century. To crack open his find, Hole tried a rock saw, an angle grinder, a drill, even putting the thing in acid, but not even a sledgehammer could make a crack. That’s because what he was trying so hard to open was no gold nugget. As he found out years later, it was a rare meteorite.https://www.sciencealert.com/man-holds-onto-rock-for-years-thinking-it-was-gold-turns-out-it-s-a-super-rare-meteorite
