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 / The universe is less uniform than we thought—cosmology may need a radical rethink
Modern cosmology rests on a simple assumption: If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological principle.
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 ...
Phys.org / Acceptor molecule upconverts low-energy green light to high-energy purple with high efficiency
Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply ...
Phys.org / Single-atom catalyst turns lignin into valuable chemicals with near-complete conversion
Researchers at The University of Manchester and Hebei University of Technology have identified how a new class of catalyst can break down lignin into useful chemical building blocks, offering a more sustainable route to replace ...
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 / Ancient gum disease may have helped reshape jaws before human brains expanded
Human evolution is generally explained through changes in brain size, locomotion or tool use, but new research from Wits University suggests that gum disease and changes in facial structure may have been important factors ...
Phys.org / Baker's yeast shows potential in treatment of persistent fungal infection
Millions of women worldwide suffer from vaginal yeast infections. These infections are most commonly caused by the fungus Candida albicans and can lead to symptoms ranging from itching and burning to recurrent inflammation. ...
Phys.org / XMM-Newton and Chandra help revise distance to Milky Way's outer spiral arms
The European Space Agency's XMM-Newton and NASA's Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance ...
Medical Xpress / Fear-learning circuit shows how stress disrupts brain's ability to suppress trauma
Fear is often thought of as a negative emotion but is actually a natural protective response to perceived threats or danger. It helps us survive. When we experience a situation that causes fear, it becomes stored in our brain ...
Phys.org / World's first synthetic cell with a complete life cycle could revolutionize biological engineering
While many of life's mysteries remain unsolved, every biologist can describe the basic processes performed by a living organism, including energy use, reproduction, growth and development. While these characteristics can ...
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 ...
