Phys.org / 'Dead stars' may have surprisingly healthy appetites
"Dead stars" known as white dwarfs have already shown the potential to help us better understand how planetary systems, including our own solar system, take shape and evolve. Now, research from the University of Michigan ...
Phys.org / Burning soil and peat drove most emissions in Canada's record 2023 wildfire season, study finds
Most of the carbon released during Canada's record-breaking 2023 wildfire season came from burning soil and peat, rather than trees, according to new research from McMaster University.
Phys.org / Sharks, spines and speed: The hidden architecture behind different swimming styles revealed
"Shark Week," which kicks off this week, has captivated audiences for decades with stories of these powerful ocean predators. But the secret behind their extraordinary swimming abilities lies far deeper than their impressive ...
Phys.org / Research cautions that sometimes working together can actually spur inequality
Encouraging people to contribute to a common good can have a surprising drawback: a risk that rewards become concentrated among a smaller group, putting the rest at a disadvantage. Put more simply, "equality and cooperation ...
Phys.org / Long-term study finds widespread lithium in drinking water across communities in the western U.S.
Lithium in drinking water is a widespread and persistent source of human exposure across Tribal communities in the Western United States, according to a new study from Columbia University Mailman School of Public Health. ...
Phys.org / AI tools for predicting protein folding produce chemically impossible structures and need human oversight
Researchers at Rensselaer Polytechnic Institute (RPI) have found that today's leading artificial intelligence tools for predicting protein structures routinely generate results that are physically and chemically impossible, ...
Phys.org / Biodegradable implant can deliver targeted cancer immunotherapy while protecting healthy tissue
Scientists at Houston Methodist Research Institute have developed a biodegradable implant designed to deliver cancer-fighting immunotherapy drugs directly into tumors over an extended period, a strategy that could improve ...
Tech Xplore / AI underwater robots can now track diver stress via exhaled bubbles
University of Minnesota Twin Cities researchers have developed a first-of-its-kind AI system that allows underwater companion robots to monitor a diver's health in real time simply by "watching" their exhaled bubbles.
Phys.org / First 3D views explain how primate cone pigments distinguish red from green
Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green ...
Phys.org / Light reveals transient electronic step behind a hidden state in metal-organic framework
A fleeting photoinduced electronic state and the subsequent formation of a photoinduced hidden state in a metal–organic framework were captured in just 30 femtoseconds by researchers at Science Tokyo, Tohoku University and ...
Tech Xplore / Are gas turbines ready for the hydrogen economy?
Can we fuel gas turbines with hydrogen instead of fossil fuels and cut 15% of global carbon dioxide (CO2) emissions? Gas turbines generate around 22% of the world's electricity. Replacing fossil fuels is a key step toward ...
Phys.org / Hidden DNA copying may give bacteria a faster route to antibiotic resistance
The dangers of antibiotic overuse have become increasingly clear in recent decades. Excessive use accelerates the evolution of bacterial resistance to antibiotics, raising the alarming prospect of infections that no longer ...
