Phys.org / Pregnancy complications may have helped wipe out Neanderthals
Neanderthals disappeared from the fossil record approximately 40,000 years ago. Their extinction was a gradual process over thousands of years, and theories as to why include competition with modern humans and rapid climate ...
Phys.org / Evidence points to early goat and sheep dairy consumption in Neolithic Iran
Approximately 9,000 years ago, human communities in Southwest Asia underwent a dramatic transformation, known as the Neolithic revolution. This period was marked by pronounced changes in how they lived and sourced food, with ...
Phys.org / Atom-thin electronics withstand space radiation, potentially surviving for centuries in orbit
Atom-thick layers of molybdenum disulfide are ideally suited for radiation-resistant spacecraft electronics, researchers in China have confirmed. In a study published in Nature, Peng Zhou and colleagues at Fudan University ...
Phys.org / How early farming unintentionally bred highly competitive 'warrior' wheat
An evolutionary "arms race" for light and space led to the early domestication of wheat, according to new research that could offer fresh insights into crop design. The study led by Dr. Yixiang Shan and Professor Colin Osborne, ...
Phys.org / How massive lava fields formed in the Pacific Northwest
Volcanic eruptions are significant geologic hazards. Underwater volcanoes are challenging to study, yet they play an integral role in marine geology and may cause destructive tsunamis that can threaten coastal communities.
Phys.org / 'All-in-one,' single-atom could power both sides of water splitting
Green hydrogen production technology, which utilizes renewable energy to produce eco-friendly hydrogen without carbon emissions, is gaining attention as a core technology for addressing global warming. Green hydrogen is produced ...
Phys.org / Cleaner fish show intelligence typical of mammals
Researchers at Osaka Metropolitan University in Japan have discovered a previously undiscovered behavior in cleaner wrasse (Labroides dimidiatus). When presented with a mirror, the tiny fish not only recognized themselves, ...
Phys.org / A survival strategy inside stressed cells: Ribosomes in pairs
Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients or sudden drops in ...
Phys.org / 3D method can accurately measure gravity in wide binary stars, as demonstrated by pilot study
Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of gravity in the low acceleration ...
Phys.org / Scientists reveal best- and worst-case scenarios for a warming Antarctica
The climate crisis is warming Antarctica fast, with potentially disastrous consequences. Now scientists have modeled the best- and worst-case scenarios for climate change in Antarctica, demonstrating just how high the stakes ...
Phys.org / REGALADE: The most extensive catalog of galaxies for modern astronomy
An international team of scientists led by the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC) has presented REGALADE, an unprecedented catalog covering ...
Phys.org / How choices made by crowds in a train station are guided by strangers
In crowds, most people are strangers to you, and everyone else for that matter. However, until now, the effect of stranger-to-stranger interactions on the choices people make in crowds has not been properly examined. Ziqi ...
