Tech Xplore / OpenAI says its AI technology acted on its own in an 'unprecedented' hack of another company
ChatGPT maker OpenAI said Tuesday that its artificial intelligence system hacked into another AI company on its own in what the company called an "unprecedented cyber incident."
Science X / Beneath pale ash, a quantum microscope reveals hidden traces of Neanderthal fire use preserved for millennia
An ancient hearth at El Salt (Spain) is giving up its secrets—not with flames, but with physics. Scientists have already established that Neanderthals used to make fires at this site (spanning from 80,000–45,000 years ago), ...
Medical Xpress / Aspirin reverses diet-driven depression-like behavior in mice
Depression is among the most common psychiatric disorders, estimated to affect between 280 million and 332 million people worldwide. This disorder is characterized by persistent sadness and hopelessness, low energy, a loss ...
Phys.org / Scientists turn modern biobanks into a new window on human evolution
For more than a century, scientists have sought to reconstruct human evolution using diverse lines of evidence, including fossils, genetic variation across populations and ancient DNA. Building on these approaches, researchers ...
Phys.org / Unraveling the climate behind the collapse of Bronze Age civilizations
The most severe droughts in the ancient Eastern Mediterranean arose when multiple natural climate cycles coincided, according to a new study from Stockholm University published in Science Advances. The findings shed new light ...
Phys.org / Oxygen collisions at the LHC show new indications of extreme state of matter
All four main LHC experiments have found new signs that oxygen and neon collisions may create the extreme state of matter that existed during the first microseconds after the Big Bang.
Phys.org / Orcas filmed ramming one of the world's heaviest fish so hard it explodes, possibly for fun
Orcas are known to be smart and ruthless hunters. They've been observed hunting a variety of prey, with some species, such as whales, larger than themselves. They use a wide range of strategies to hunt and kill prey, but ...
Medical Xpress / Spontaneous changes in brain state influence the readiness to form memories, neuroscientists find
Most everyday moments are quickly forgotten, while others stay with us for a lifetime. How the brain determines which memories are retained and which are lost remains an open question.
Medical Xpress / Scientists find compound that may help muscles stay strong as we age
Skeletal muscle is one of the first tissues to decline with age. This decline can lead to weakness, scarring, fat accumulation inside muscle and the loss of fast-twitch muscle fibers that are important for quick, powerful ...
Phys.org / Quantum Zeno effect could freeze computations as qubit systems scale up
The promise of quantum computing is to solve complex problems faster and more energy-efficiently than today's supercomputers—from optimizing logistics to simulating molecules. This goal is coming within reach as the number ...
Medical Xpress / Injectable biomaterial harnesses the immune system to promote brain repair after stroke
Biomedical engineers at Duke University have developed an injectable biomaterial that helps transform the cavity left behind after a stroke caused by a blood clot into an environment more supportive of repair. By recruiting ...
Phys.org / Quantum dots reveal hidden light waves on metal surfaces
Photographs can reveal things that are otherwise impossible for the naked eye to see, be they distant galaxies or microscopic cells. Researchers at Osaka Metropolitan University have developed a practical and versatile imaging ...
