Phys.org / Ultrafast electron diffraction captures atomic layers twisting in response to light
A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like dancers following a beat.
Phys.org / Water causes rock to shift on the Matterhorn
When water penetrates rock crevices in permafrost, it transports heat deep underground, where it causes the frozen rock to thaw. Researchers at the WSL Institute for Snow and Avalanche Research (SLF) have explored which processes ...
Phys.org / Pleiades star cluster revealed as just one part of a vast stellar family
Astronomers at the University of North Carolina at Chapel Hill have discovered that the famous Pleiades star cluster, the "Seven Sisters" often spotted on winter nights, is just the bright tip of a much larger stellar family. ...
Phys.org / Ultrafast light-driven electron slide discovered
When an intense laser pulse hits a stationary electron, it performs a trembling motion at the frequency of the light field. However, this motion dies down after the pulse, and the electron comes to rest again at its original ...
Phys.org / Cow cells defy aging, opening the door to affordable lab-grown beef
A new study shows, for the first time, that cow cells can naturally become immortal—continuing to divide indefinitely without genetic modification or any abnormal transformation. This overturns long-held assumptions that ...
Phys.org / First confirmed coronal mass ejection spotted on a star beyond the sun
Astronomers using the European Space Agency's XMM-Newton space observatory and the LOFAR telescope have definitively spotted an explosive burst of material thrown out into space by another star—a burst powerful enough to ...
Phys.org / Hidden Arctic leaks: Natural seepage of oil and gas uncovered off Northeast Greenland
A large research study by an international team of scientists led by Christoph Böttner from Aarhus University shows clear evidence of extensive natural hydrocarbon seepage along the Northeast Greenland margin—one of the ...
Phys.org / Computational process could condense decades of disease biology research into days
At 10 one-millionths of a meter wide, a single human cell is tiny. But something even smaller exerts an enormous influence on everything a cell does: proton concentration, or pH. On the microscopic level, pH-dependent structures ...
Phys.org / Light pollution: The silent threat to the planet that's easily solved
New research has revealed for the first time the full extent of how "Artificial Light At Night" (ALAN) is increasing carbon released by plants and animals across continents—without any increase in the carbon they absorb. ...
Phys.org / Evidence of ancient underground water reveals Mars may have stayed habitable longer than believed
Scientists from New York University Abu Dhabi (NYUAD) have uncovered new evidence that water once flowed beneath the surface of Mars, revealing that the planet may have remained habitable for life much longer than previously ...
Phys.org / Surprising numbers of childfree people emerge in developing countries, defying expectations
A new analysis suggests that some developing countries have unexpectedly large numbers of childfree people; that is, people who have not had children and do not want to in the future. Zachary Neal and Jennifer Neal of Michigan ...
Phys.org / AI helps identify genomic 'time capsule' that distinguishes species
In a recent study, scientists from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) have utilized cutting-edge artificial intelligence methods to identify a region of the X chromosome that has maintained ...
