Phys.org / More colorful songbirds face higher extinction risk
In the humid jungle of Vietnam, Natalia Ocampo-Peñuela and Monte Neate-Clegg spent hours patiently waiting to spot the rare "Halloween bird." Officially known as the collared laughingthrush, this songbird has striking orange, ...
Phys.org / Cutting emissions more, removing carbon less could save 33,000 U.S. lives yearly
Published in Nature Climate Change, new research from the University of Wisconsin–Madison finds that reaching net-zero emissions by midcentury would substantially improve public health in the United States. However, climate ...
Phys.org / Deep inside crocodile skulls, 100 million years of brain evolution barely registers
Although modern crocodiles, alligators, caimans and gharials are restricted to the tropics, their fossil record tells a very different story. Ancient crocodylians once inhabited much of the globe and exhibited a remarkable ...
Phys.org / Ozone depletion began decades before discovery of ozone hole, scientists find
The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in Earth's protective layer of stratospheric ozone. Industrial chemicals known as chlorofluorocarbons (CFCs), then widely used as ...
Tech Xplore / Electric car analysis reveals moral case for accelerating green transition
Recently, it has been argued that a rapid transition is unjust—particularly because of concerns about mining critical minerals, including for EVs. Specific concerns have been raised about deaths among artisanal and small-scale ...
Phys.org / Superworms could be the future of skeleton cleaning
Superworms, a mealworm-like form of beetle larva commonly used as pet food, are efficient cleaners of skeletons, according to a study published in PLOS One by Fatemeh Rastekar of Ferdowsi University of Mashhad, Iran, and ...
Phys.org / Evolutionary origins of 'junk DNA' may provide new clues to cancer
In cancer research, one person's junk is increasingly becoming another person's treasure. Scientists have uncovered new evidence showing how recently evolved "junk DNA" genetic elements can become integrated into ancient ...
Phys.org / Escaped flowerhorn fish threaten biodiversity, pose potential public health risks in Laguna, Philippines
A hardy aquarium fish prized for its golden hue, the ornamental Flowerhorn cichlid (Amphilophus spp.) has become a problem for the residents of San Pablo City, Laguna: It is increasingly taking on an outsized role in both ...
Tech Xplore / AI changes its behavior around authority... and that could be risky
Artificial intelligence doesn't just learn how humans talk. It may also be learning who gets listened to. A new study from researchers at the University of North Carolina at Chapel Hill found that large language models, the ...
Phys.org / Tree size, not age, may speed habitat recovery for endangered Indiana bats
Bugs run rampant in the summer, and if you have ever suffered a mosquito bite and regretted not putting on bug spray, you should know about nature's insect repellent: the Indiana bat. Federally endangered since 1967, the ...
Tech Xplore / AI-human relationships are real and come with risks, researchers find
Human-AI relationships are no longer confined to the domain of science fiction. As the technology has developed, AI chatbots have evolved from playing a role in search engines and image-generation tools into confidants, therapists ...
Tech Xplore / Tandem solar cell sets 25.5% efficiency record with CIGS-perovskite design
A Berlin-based team from HZB and Center for the Science of Materials Berlin (CSMB) at Humboldt-Universität zu Berlin has set a new record for a tandem solar cell. Using a combination of a CIGS semiconductor layer and perovskite, ...
