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 / 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 / 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 / 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 / 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 / Webb reveals merger scars in galaxies that stopped forming stars 9 billion years ago
Research has shed new light on why some distant galaxies suddenly stop forming stars. An international team led by astronomers at the University of Nottingham has used the James Webb Space Telescope to study a large sample ...
Phys.org / World's oceans break June heat record: EU monitor
The world's oceans just experienced their hottest June on record and could set fresh highs in the months ahead as El Nino and climate change drive temperatures even higher, scientists said Wednesday.
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 / NASA rolls out three robotic moon missions as 2029 lunar base plans take shape
NASA on Tuesday announced new uncrewed missions to aid in the future creation of a lunar surface base, a project beginning to take shape despite recent setbacks.
Phys.org / Martian dust storms may generate atmospheric electrical conditions that could impact future missions
A new study by a doctoral researcher at The University of Alabama in Huntsville (UAH), part of The University of Alabama System, suggests global dust storms on Mars may organize the Martian atmosphere into regions favorable ...
