Phys.org / Salt may have pushed us further into Snowball Earth 700 million years ago
Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago. During a period geologists call Snowball Earth, ice sheets crept from the poles all the way to ...
Phys.org / Largest known Mesozoic crocodyliform egg clutch discovered in Brazil
In a study published in the Journal of Vertebrate Paleontology, researchers Dr. Giovanna M. X. Paixão and her colleagues analyzed the fossilized remains of three Upper Cretaceous egg clutches. One of these clutches, totaling ...
Phys.org / Gravitational waves reveal hidden structure of galactic centers
A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The ...
Phys.org / Many scientists now use AI but fail to disclose it, study finds
When scientists employ generative AI tools like ChatGPT to help with tasks such as editing and translation for their academic writing, many journals now ask them to disclose this assistance. The rules are intended to maintain ...
Medical Xpress / Cheek cells may provide clues to schizophrenia risk
A simple cheek swab could one day provide a quick and noninvasive diagnostic test for schizophrenia. A new study published in Science Advances has identified higher levels of two biological markers in the cheek swabs of patients ...
Medical Xpress / Three distinct ADHD biotypes identified using a novel brain-first, data-driven approach
Attention-deficit/hyperactivity disorder or ADHD translates in different ways across the population, unlike the overgeneralized version presented on social media. A recent study further solidified this idea by identifying ...
Phys.org / Satellite images uncover new threat to emperor penguins during their annual molt
The tall black-and-white residents of Antarctica, who waddle around its icy landscape, are in peril thanks to the rapidly warming global climate. Emperor penguins go through an annual transformation called catastrophic molting, ...
Phys.org / New study reveals differences between 'Demon Slayer' bamboo muzzle and actual bamboo
In storytelling, even small visual details can become unforgettable. In the globally popular anime "Demon Slayer," one such detail is the short bamboo muzzle worn by a central character. It looks simple and believable, just ...
Medical Xpress / An AI-informed model of human reward-based learning: Hybrid approach could aid studies of mood disorders
People's decisions are known to be influenced by past experiences, including the outcomes of earlier choices. For over a century, psychologists have been trying to shed light on the processes underpinning human decision-making ...
Tech Xplore / Liquid-metal pupil helps an artificial eye adapt to sudden light changes
Computer vision technologies are artificial intelligence (AI)-powered systems that can capture, analyze, and interpret visual data captured from real-world environments. While these systems are now widely used, many of them ...
Phys.org / A superradiant clock phase emerges when Rydberg atoms meet quantum light, simulations suggest
Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and develop quantum technologies, ...
Phys.org / Material previously thought to be quantum is actually a new, non-quantum state of matter
Magnetic materials in a quantum spin liquid phase are of great interest in the pursuit of exotic state of matter and quantum computation. But in the quantum realm, things are not always what they seem. A study, published ...
