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 / 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 ...
Phys.org / What made trees possible? New research points to drought
A study is reframing a fundamental question in plant evolution: What made trees possible? Researchers from Cal Poly Humboldt, Yale University, the University of Hohenheim in Germany and the Czech Academy of Sciences set out ...
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 / Cosmic dust could play key role in cracking long-standing mystery of solar corona heating
A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly ...
Phys.org / Were Clovis foragers in Late Pleistocene North America big-game hunters, or just big-game scavengers?
There are currently 15 well-documented Late Pleistocene localities in North America in which Clovis points are found associated with proboscidean remains (of mammoth, mastodon and gomphothere). Archaeologists routinely assume ...
Phys.org / Primate brains might have evolved to 'catch up' with larger bodies, but then kept growing
A new analysis supports the previously overlooked "brain lag" hypothesis—the idea that, in some primate lineages, the evolution of larger body size preceded the evolution of larger brain size—while also building on that hypothesis ...
Phys.org / Lake Chad supports 2.48 million waterbirds, emerging as one of Africa's top wetland refuges
A study titled "Monitoring major biodiversity stronghold in war zones: model predicts Lake Chad remains Africa's most important wetland for waterbirds" estimates that Lake Chad supports nearly 2.5 million waterbirds, making ...
Phys.org / Sun-powered sponges may generate 11% of tropical coral reef productivity
In marine environments, sponges tend to eat other organisms to get their nutrients. But a study published in Functional Ecology by researchers at the University of Amsterdam's Institute for Biodiversity and Ecosystem Dynamics ...
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 / Orbit overload could devastate astronomy if 1.7 million proposed satellites brighten night sky
A new European Southern Observatory (ESO) study has found that current proposals to launch more than 1.7 million satellites into orbit, including extremely bright ones, would have "devastating consequences for astronomy." ...
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 ...
