New findings about ions around comets
Sofia Bergman, Swedish Institute of Space Physics (IRF) and Umeå University, will defend her doctoral thesis on low-energy ions around comet 67P/Churyumov-Gerasimenko on 26 November. Observing low energy ions is notoriously difficult because their p.....»»
Researchers uncover source rocks of the first real continents
Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed—a revised origin story that doesn't require the start of plate tectonics or any external factor to explain their formation. Instead, the findings pub.....»»
Decay of sunspot pair elucidates properties of nearby moving magnetic features
Scientists studying sunspots have found important clues about magnetic features in their decay that will help understand the evolution and real origin of these mysterious magnetic phenomena. The findings are published in The Astrophysical Journal......»»
New data, same appearance for M87*
Nearly five years ago, a globe-spanning team of astronomers gave the world its first-ever glimpse of a black hole. Now the team has validated both their original findings and our understanding of black holes with a new image of the supermassive black.....»»
Stars travel more slowly at Milky Way"s edge: Galaxy"s core may contain less dark matter than previously estimated
By clocking the speed of stars throughout the Milky Way galaxy, MIT physicists have found that stars further out in the galactic disk are traveling more slowly than expected compared to stars that are closer to the galaxy's center. The findings raise.....»»
Discovery of high order skyrmions and antiskyrmions
Researchers at the University of Augsburg and the University of Vienna have discovered co-existing magnetic skyrmions and antiskyrmions of arbitrary topological charge at room temperature in magnetic Co/Ni multilayer thin films. Their findings have b.....»»
Sika deer overpopulation endangers beech forests in Southern Kyushu, Japan
Kyushu University researchers have found that Japanese beech (Fagus crenata) in the forests of southern Kyushu have seen reduced growth, due to soil erosion caused by the overpopulation of sika deer (Cervus nippon). Their findings, which were publish.....»»
Deep learning reveals molecular secrets of explosive perchlorate salts
Perchlorates are a class of compounds that are notorious for their explosive nature. This raises safety concerns during experiments involving complex compounds that contain perchlorate ions, since explosions can be triggered even by the slightest sho.....»»
Rare decay of the Higgs boson may point to physics beyond the Standard Model
Particle physicists have detected a novel decay of the Higgs boson for the first time, revealing a slight discrepancy in the predictions of the Standard Model and perhaps pointing to new physics beyond it. The findings are published in the journal Ph.....»»
New design improves water decontamination via plasma jet
Plasma is an ionized gas—that is, a gas containing electrons, ions, atoms, molecules, radicals, and photons. It is often called the fourth state of matter, and surprisingly, it permeates everything. Plasmas, which are artificially generated by tran.....»»
Global warming found to have a bigger effect on compact, fast-moving typhoons
A research group from Nagoya University in Japan has found that larger, slower-moving typhoons are more likely to be resilient against global warming. However, compact, faster-moving storms are more likely to be sensitive. These findings suggest an i.....»»
Live animal transport regulations not "fit for purpose," large international study finds
A "fitness check" of regulations in five countries, meant to protect animals during transportation, has deemed that they all fall short of fully protecting animals during transport. Findings from this interdisciplinary work involving animal welfare s.....»»
Gravity helps show strong force strength in the proton
The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the swirl of gigantic galaxies. These awesome displays sho.....»»
When conditions cool down, a bacterial prey species becomes the predator
In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature. Marie Vasse of MIVEGEC, France, and colleagues have published these findings in PLOS Biology......»»
Ecosystem from 3.4 billion years ago: New pieces discovered in the cradle of life puzzle
A new study has unraveled key findings about the earliest life forms on Earth. In rock samples from Barberton, Republic of South Africa, researchers were able to find evidence of an unprecedented diverse biological carbon cycle established at 3.42 bi.....»»
Enabling distributed quantum sensors for simultaneous measurements in distant places
A research team has succeeded in implementing a distributed quantum sensor that can measure multiple spatially distributed physical quantities with high precision beyond the standard quantum limit with few resources. Their findings are published in t.....»»
Mars Express finds evidence of large water deposit at the Medusae Fossae Formation
Windswept piles of dust, or layers of ice? ESA's Mars Express has revisited one of Mars's most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometers below ground—the most water ever f.....»»
Unveiling sodium channel dynamics: New insights into cell biology using high-speed atomic force microscopy
The transport of ions to and from a cell is controlled by pore-forming proteins embedded in the cell membrane. In particular, voltage-gated sodium channels (VGSCs) govern the transfer of sodium (Na+) ions, and play an important role in the regulation.....»»
Global collaboration of scientists needed to solve polycrisis, say researchers
Heightened global interconnectivity and human pressures on planetary boundaries generate increasingly harmful and extensive crisis interactions that make it impossible to solve any one problem alone, findings published in Global Sustainability reveal.....»»
Big dogs vs. small dogs: Which sizes face higher risks of which diseases?
A study of more than 25,000 U.S. dogs and 238 breeds has linked dog size to varying patterns of risk for health conditions over the course of a dog's lifespan. Yunbi Nam of the University of Washington, U.S., and colleagues present these findings in.....»»
Women farmers quantitatively linked to better community well-being
Having more women in agriculture is associated with greater community well-being, according to researchers at Penn State and the University of Wisconsin-Madison. Their work is the first to quantitatively assess this link, and their findings suggest t.....»»
