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…
Researchers at the Herbert Wertheim School of Public Health and Human Longevity Sciences at the University of California, San Diego have found that recent federal funding cuts for health equity and gender identity research have disproportionately affected scientists in the very communities the research aims to support. The results of this study were published on May 5, 2026. Lancet Community Health – Americas. The termination of these grants not only halted specific research projects, but also the careers of many scientists studying the health of marginalized communities. When funding for these topics is lost, researchers with the deepest expertise in…
The first study of U.S. adults suggests that not all strangers you befriend on social media help you feel less lonely. In fact, connecting with people you don’t know in person on social media can actually make you feel more lonely, according to scientists at Oregon State University. In a nationally representative study of more than 1,500 adults ages 30 to 70, connecting with people you know in real life online was not associated with increased feelings of loneliness, but it was also not associated with decreased feelings of loneliness. The findings suggest that “people experiencing loneliness may want to…
