Phys.org / Dark energy and quantum gravity may be deeply intertwined
For close to a century, physicists have pursued a way to unite gravity with quantum mechanics. Known as quantum gravity, this goal has remained frustratingly out of reach so far. Similarly elusive is the force of dark energy, ...
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 / Rising carbon dioxide is supercharging grass growth in African savannas, study finds
Rising atmospheric carbon dioxide is boosting grass growth in Africa's water-limited savannas, according to a new study led by the University of Sheffield.
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 / Honeybees struggle to gather nectar in August, direct measurements reveal
Letting late-summer weeds grow could help honeybees when they find it most challenging to gather nectar, according to new research published in the journal, Functional Ecology.
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 / '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 / 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 / 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 ...
