Scientists studying genetic data from over a quarter million people have uncovered new clues about what controls how fast the gut moves. They identified multiple DNA regions linked to bowel movement f...
Scientists found that nasal cells act as a first line of defense against the common cold, working together to block rhinovirus soon after infection. A fast antiviral response can stop the virus before...
A new study reveals that super agers over 80 have a distinct genetic edge. They are much less likely to carry the gene most associated with Alzheimer’s risk, even when compared with other healthy seni...
A new blood test may reveal Crohn’s disease years before symptoms begin. The test detects an unusual immune response to gut bacteria in people who later develop the condition. By studying healthy rela...
Type 2 diabetes becomes more dangerous to the heart the longer a person has it. Researchers found that after several years, red blood cells can begin interfering with healthy blood vessel function. Th...
Chemotherapy’s gut damage turns out to have a surprising upside. By changing nutrient availability in the intestine, it alters gut bacteria and increases levels of a microbial molecule that travels to...
Giant kangaroos that lived during the Ice Age may not have been as slow and grounded as once believed. A new study finds their leg bones and tendons were likely strong enough to support hopping, despi...
Scientists are finding new ways to replace expensive, scarce platinum catalysts with something far more abundant: tungsten carbide. By carefully controlling how tungsten carbide’s atoms are arranged a...
Falling space junk is becoming a real-world hazard, and scientists have found a clever new way to track it using instruments already listening to the Earth itself. By tapping into networks of earthqua...
Pancreatic cancer may evade the immune system using a clever molecular trick. Researchers found that the cancer-driving protein MYC also suppresses immune alarm signals, allowing tumors to grow unnoti...
A distant Sun-like star suddenly went dark for months, stunning astronomers who quickly realized something massive was passing in front of it. Observations revealed a gigantic disk of gas and dust fil...
Astronomers have spotted a rare, rule-breaking quasar in the early Universe that appears to be growing its central black hole at an astonishing pace. Observations show the black hole is devouring matt...
A groundbreaking new radio image reveals the Milky Way in more detail than ever before, using low-frequency radio “colors” to map the galaxy’s hidden structures. The image is sharper, deeper, and wide...
Researchers have found that a natural aging-related molecule can repair key memory processes affected by Alzheimer’s disease. The compound improves communication between brain cells and restores early...
Aging immune cells may be sabotaging the body from within. Researchers found that macrophages produce a protein that locks them into a chronic inflammatory state, making infections like sepsis more de...
Chronic inflammation may be quietly reshaping the colon and making it more vulnerable to early-onset colorectal cancer. Scientists found that colon tissue in younger patients was stiffer, even in area...
Scientists are warning that a little-known group of microbes called free-living amoebae may pose a growing global health threat. Found in soil and water, some species can survive extreme heat, chlorin...
A large, decades-long study suggests that signs of ADHD in childhood may have consequences that extend well beyond school and behavior. Researchers followed nearly 11,000 people from childhood into mi...
People with spinal cord injuries often lose movement even though their brains still send the right signals. Researchers tested whether EEG brain scans could capture those signals and reroute them to s...
Locust swarms can wipe out crops across entire regions, threatening food supplies and livelihoods. Now, scientists working with farmers in Senegal have shown that improving soil health can dramaticall...
