Recent research published in JAMA Psychiatry Popular artificial intelligence chatbots suggest that when users type messages containing signs of mental illness, they tend to respond with inappropriate or unhelpful responses. The findings provide evidence that relying on these digital tools for mental health advice can pose a significant safety risk for people experiencing severe psychological distress. Large-scale language models are advanced artificial intelligence systems designed to understand and generate human text. They analyze vast amounts of internet data to predict which word will logically come next in a given sentence. This mathematical process essentially allows computer programs to recognize structural…

Physicists have traditionally divided all elementary particles in our three-dimensional universe into two categories: boparticles and fermions. Bosons primarily include force-carrying particles such as photons, while fermions make up ordinary matter such as electrons, protons, and neutrons. This simple partition begins to break down in low-dimensional systems. Since the 1970s, scientists have predicted the existence of a third type of particle known as anion, which lies between bosons and fermions. In 2020, researchers experimentally observed these unusual particles at the interface of a supercooled, highly magnetized, one-atom-thick (and therefore two-dimensional) semiconductor. Now, scientists at Okinawa Institute of Science and Technology…

Why do people hold on to hope when romantic signals are mixed? Our new research suggests that sexual arousal may make it harder to recognize signs of disinterest. “You’re attractive and smart, but I’m looking for something else.” I thought this was a clear and kind way to reject someone. I was wrong. One pilot study tested different rejection messages to see which ones made it clear to people that a potential partner was not interested. I didn’t want to hurt the participants unnecessarily, so I initially softened any negative reactions with compliments. But after testing it a few times,…

Diving into the deep ocean pushes marine mammals to their physical limits. When animals are underwater for long periods of time, organs other than the heart and brain can switch to “anaerobic” (oxygen-free) metabolism, leading to lactic acid buildup. Although many diving species have evolved methods to reduce the risk of “bending,” nitrogen bubbles can still form in the bloodstream. Scientists have long believed that these animals primarily recover while floating or swimming to the surface between dives. New research published in Frontiers in physiology This suggests that recovery may continue long after the seals are out of the water.…

Drywood termites are good at staying hidden. They live in wooden structures, silently feeding and expanding their colonies in areas that homeowners may not notice until the damage begins. But their covert lifestyle also relies on a fragile biological process: molting. Researchers at the University of California, Riverside have shown that bistrifluron, a chemical that prevents the formation of new termite exoskeletons, can destroy termite colonies in dry wood by interfering with the insect’s ability to grow. The survey results are Journal of Economic Entomology. In clinical testing, this treatment killed approximately 95 percent of colonies and did not pose…

Recent research published in natural neuroscience This suggests that the brain is more mechanically connected to the body than previously realized. Scientists have discovered that contractions of the abdominal muscles compress blood vessels connected to the spine and brain, pushing out fluid within the skull that gently moves the brain. This physical shake provides evidence of how exercise benefits brain health by flushing out cellular waste. Scientists set out to understand the specific mechanical origins of brain movements in awake animals. The central nervous system is encased in thick bone and appears insulated from the physical forces of the rest…

Archaeologists working at ancient ruins in central China have found evidence that early humans may have become more inventive while surviving the harsh Ice Age. The discovery was made at the Lingjing site, where researchers have spent more than a decade excavating animal bones and sophisticated stone tools associated with extinct human relatives. man of july. New research has revealed that the site dates back some 146,000 years, and that it was located during a cold Ice Age, rather than during a warmer period as scientists once believed. The findings challenge the long-held idea that creativity and technological progress developed…

Recent research published in journals natural mental health suggest that children who exhibit high levels of attention-deficit hyperactivity disorder traits are more likely to experience psychological distress into middle age. This study provides evidence that this long-term mental health burden is partially caused by social exclusion. Systemic barriers, such as limited access to health care, social support, and economic security, appear to play a large role in this process. Attention-deficit hyperactivity disorder, commonly known as ADHD, is a condition that involves differences in how people manage their attention, regulate their activity levels, and control their impulses. Scientists recognize that people…

Scientists studying axolotls, zebrafish and mice have discovered a common set of genes that could one day help researchers develop treatments to regenerate human limbs. The survey results are Proceedings of the National Academy of Sciencessuggesting potential new directions for regenerative medicine and gene therapy. “This important study brought together three laboratories and worked across three organisms to compare regeneration,” said Josh Currie, assistant professor of biology at Wake Forest. The same laboratory studies the Mexican axolotl salamander. “It showed that there is a universal, unifying genetic program that drives reproduction in very different species, such as salamanders, zebrafish, and…
