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.
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 ...
Phys.org / 'Pac-Man' enzyme breaks down bioplastics and penicillin in laboratory tests
In the ocean, plastic waste collects to form large garbage patches that endanger marine life. This is partly because the synthetic plastic polymers used today can only be broken down biologically—that is, by microorganisms—at ...
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 ...
Phys.org / As global heating heads to 1.8°C, is it time to consider the 'Voldemort' of climate policy?
The world is set to miss the 1.5°C global warming target, and plans are underway for U.N. climate talks in the Pacific and Turkey.
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 / 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 ...
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 ...
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 ...
Phys.org / Scientists studying cockroach milk and nose-blowing win Ig Nobel prizes for quirky science
Ten research teams were honored Thursday at a satirical science awards ceremony that was hosted outside the U.S. for the first time due to travel concerns.
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 ...
Phys.org / Trees use a 'muscle' to correct their posture—a newly discovered role for tension wood
A research team from INRAE and the University Clermont Auvergne has shown that trees are capable of correcting a curvature they detect in their stems through a specific biological process. In the study, young trees with bent ...
