Medical Xpress / Why nighttime heat drives a surge in suicide-related calls to crisis lines in Louisiana
Extreme heat poses serious risks to physical health but can also trigger a mental health emergency for some people. While the link between heat and suicide is well-documented, the specific stressors that drive someone to ...
Medical Xpress / Newly found immune cells link strep throat to psoriasis
A common strep throat infection can trigger guttate psoriasis by altering the behavior of key immune cells, according to a new study from Karolinska Institutet published in eBioMedicine. The findings suggest how an infection ...
Tech Xplore / AI 'blind spot' could allow attackers to hijack self-driving vehicles
A newly discovered vulnerability could allow cybercriminals to silently hijack the artificial intelligence (AI) systems in self-driving cars, raising concerns about the security of autonomous systems increasingly used on ...
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 / New generation of climate models sheds first light on long-standing Pacific puzzle
Researchers have long been puzzled by the observed cooling of the eastern tropical Pacific and the Southern Ocean accompanying global warming. Existing climate models have failed to capture this pattern. At the Max Planck ...
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 / 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 / Pushing the right buttons: Fern guides its embryo's sense of up and down
Passing on fundamental life lessons from parent to offspring is not unique to humans and animals. Ferns do it too. Not with words, but through pressure. By applying force at precisely the right locations, a fern tells its ...
Phys.org / Impact-formed glass provides evidence of cosmic collision in Brazil about 6 million years ago
For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites ...
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 ...
Tech Xplore / New chip-fabrication method creates 'twin' fingerprints for direct authentication
Just like each person has unique fingerprints, every CMOS chip has a distinctive "fingerprint" caused by tiny, random manufacturing variations. Engineers can leverage this unforgeable ID for authentication, to safeguard a ...
Medical Xpress / Why chronic pain lasts longer in women: Immune cells offer clues
Chronic pain lasts longer for women than men, and new research suggests differences in hormone-regulated immune cells, called monocytes, may help explain why.
