Phys.org / Stone tools suggest Neanderthals once inhabited Arabian deserts
Neanderthals are largely associated with colder climates across Eurasia. But researchers know that both Homo sapiens and Neanderthals moved through nearby Southwest Asia between about 100,000 and 50,000 years ago, and Arabia ...
Phys.org / RNA droplets may have helped start life on Earth
It's one of the origins-of-life chicken-or-egg problems: How could RNA have helped give rise to the first cells before there were cells to contain it?
Phys.org / ALMA uncovers sulfur for the first time around a rare class of supergiant star
Astronomers have discovered a chemically rich collection of sulfur-bearing molecules surrounding the rare massive star HD 87643. The observations include the first detection of sulfur monoxide and sulfur dioxide around a ...
Phys.org / Scarce emergence of new species drove the decline of African megaherbivores, study suggests
A study by the National Museum of Natural Sciences (MNCN-CSIC), the National Research Center on Human Evolution (CENIEH) and the University of Alcalá offers a new explanation for the decline of African megaherbivores. These ...
Phys.org / Natural forest regrowth offers a lower-cost path to climate and biodiversity goals
As nations race to restore ecosystems and curb climate change, research has shown that letting nature do the work is a cost-effective, viable solution. A study from the University of Queensland and the University of Newcastle ...
Phys.org / Welcome to the jungle: Newly discovered snake named after Slash from Guns N' Roses
Slash, aka Saul Hudson, is probably best known as the guitarist for Guns N' Roses. But there's more to Slash than his music. He's also a lifelong reptile lover and an avid supporter of zoos and museums. And now, he's the ...
Phys.org / Rising ocean temperatures reduce the natural carbon storage capacity of seagrass meadows
A new study published in Communications Earth & Environment, with contributions from researchers at the Leibniz Centre for Tropical Marine Research (ZMT), shows that higher seawater temperatures could significantly reduce ...
Phys.org / Hypersonic impact rapidly transforms diamond into graphite, revealing energy-absorbing mechanism
Rice University researchers have developed a way to stabilize diamond during high-temperature and low-pressure processing, creating a strong bulk composite and discovering that high-speed collisions can rapidly transform ...
Phys.org / Thinner lenses, brighter colors: Metalens research clears two hurdles for AR and VR glasses
AR and VR glasses once seen only in science fiction may soon be realized not as bulky stacks of lenses but as a single eyeglass-like optical element. That future is now closer to reality.
Phys.org / 'Shaking up' biofilm research: Active topography reduces bacterial infections
The use of antibiotics has traditionally been considered the gold standard in bacterial infection control—the more bacterial cells you kill, and the faster you kill them, the better. University of Tennessee, Knoxville Professor ...
Phys.org / Fibrinogen discovery reshapes understanding of how wounds heal
Scientists have redefined how the key blood-clotting protein fibrinogen behaves when it contacts air, overturning two decades of scientific consensus on wound healing. It is the culmination of more than a decade of international ...
Phys.org / Alternative mRNA modification lets ribosomes move nearly twice as fast
In a new study, scientists from Johns Hopkins Medicine report that an experimental mRNA-based platform has the potential to help deliver next-generation mRNA therapeutics, including vaccines to fight infectious diseases, ...
