Phys.org / Switching gravity on and off leaves particles behind, mathematical model finds
Hawking radiation causes black holes to eventually evaporate. This is because particle pairs are spontaneously created near the event horizon (the position of the last ray of light that can escape the black hole's gravitational ...
Phys.org / Five-metal 2D catalysts could convert CO₂ to CO without needing an extra electrical boost
Carbon dioxide (CO₂) is usually discussed as something the world needs to get rid of. Activities such as the burning of fossil fuels for daily use, including electricity and transportation, and industrial applications release ...
Phys.org / New 'devil flower' species discovered in Thai national park
Researchers have described a new species of leafless flowering plant found on the forest floor of a national park in western Thailand, and its otherworldly appearance has earned it a fittingly dramatic name: Thismia daemona, ...
Phys.org / Electron spin unlocks magnetic control of hydrogen surface reactions
Chemical reactions at surfaces play a central role in many processes, including catalysis and materials synthesis. It is well known that the outcome of these reactions is influenced by the translational, vibrational and rotational ...
Medical Xpress / Voice disorder may be an early sign of dementia, study suggests
Those experiencing worsening voice quality—in pitch, clarity, volume, reduced vocal range or other voice disorders—and no hearing loss may be at 58% greater risk of cognitive impairment or dementia than those who are not ...
Medical Xpress / Three psychedelic drugs affect the brain differently, brain scans in rats suggest
In recent years, psychedelic drugs have attracted growing interest as potential treatments for conditions including depression, anxiety and addiction. Although these drugs are often considered one group, researchers from ...
Tech Xplore / Supercooled water enables 3D printing of ice
Physicists from the University of Amsterdam have developed a method to print three-dimensional structures in ice. The researchers show how small pillars can be printed at an angle, making it possible to print arbitrary profiles ...
Tech Xplore / Improved method for producing sustainable hydrogen offers a surprising side benefit
Producing hydrogen is essential for some of the world's biggest industrial and agricultural needs, but it also comes with a steep environmental cost: Most hydrogen made today is generated through processes that release large ...
Medical Xpress / Neural networks reveal how experience shapes learning in both brains and machines
A new study has used a type of machine learning called a neural network to reveal how different kinds of training can change how learning happens—both in machines and in living brains.
Phys.org / BESIII sets world's most stringent direct limit on Lambda hyperon electric dipole moment
The BESIII Collaboration, led by the Institute of High Energy Physics of the Chinese Academy of Sciences, has achieved the world's most precise measurement of the electric dipole moment (EDM) of the Lambda (Λ) hyperon using ...
Phys.org / Microbes—dead or alive—can be early indicators of soil health under regenerative farming
Researchers have demonstrated a series of biological tests that could serve as "proxies" for measuring how different regenerative agriculture practices could improve soil carbon—years before it would be possible to measure ...
Medical Xpress / How the developing human brain takes instructions: Two studies reveal what guides its most important stem cells
As the human brain takes shape before birth, a remarkable type of stem cell helps give it many of the features that make it distinctly human. These cells, called radial glia, make billions of decisions that determine which ...
