For years, compulsive behaviors have been viewed as bad habits stuck on autopilot. But new research in rats found the opposite: inflammation in a key decision-making brain region actually made behavior more deliberate, not more automatic. The change was linked to astrocytes, brain support cells that multiplied and disrupted nearby circuits. The discovery hints that some compulsive behaviors may ar
A sweeping review of global research suggests that exercise—especially aerobic activities like running, swimming, and dancing—can be one of the most powerful ways to ease depression and anxiety. Across tens of thousands of people aged 10 to 90, exercise consistently reduced symptoms, often matching or even outperforming medication and talk therapy.
Researchers have uncovered the enzyme behind chromothripsis, a chaotic chromosome-shattering event seen in about one in four cancers. The enzyme, N4BP2, breaks apart DNA trapped in tiny cellular structures, unleashing a burst of genetic changes that can help tumors rapidly adapt and resist therapy. Blocking the enzyme dramatically reduced this genomic destruction in cancer cells.
Kennedy and his MAHA allies are increasingly focused on food issues as the midterms approach.
The lack of a Senate-confirmed leader is deepening the turmoil at the CDC.
A major new study suggests that eating the Nordic way could help you live significantly longer—while also helping the planet. Researchers from Aarhus University found that people who closely followed the 2023 Nordic dietary guidelines had a 23% lower risk of death compared to those who didn’t.
Researchers tracked more than 400 toddlers to see whether mRNA COVID-19 vaccination during or just before pregnancy was linked to autism or developmental delays. After detailed assessments of speech, motor skills, behavior, and social development, they found no meaningful differences between vaccinated and unvaccinated groups. Experts say the results provide strong reassurance about vaccine safety
Scientists have created the most detailed maps yet of how genes control one another inside the brains of people with Alzheimer’s disease. Using a powerful new AI-based system called SIGNET, the team uncovered cause-and-effect relationships between genes across six major brain cell types, revealing which genes are truly driving harmful changes. The most dramatic disruptions were found in excitatory
A simple shift in your evening routine may give your heart a measurable boost. In a new study, adults who stopped eating and dimmed the lights three hours before bed and extended their overnight fast by about two hours saw improvements in blood pressure, heart rate, and blood-sugar control — without cutting calories.
Scientists have uncovered a hidden partnership between pancreatic cancer and the nervous system. Support cells in the pancreas lure nerve fibers, which then release signals that accelerate early cancer growth. This creates a self-sustaining loop that helps tumors take hold. Blocking the nerve activity significantly reduced tumor growth in experiments, suggesting a new treatment strategy.
A massive review of 23 randomized trials found that statins do not cause the vast majority of side effects listed on their labels. Memory problems, depression, sleep issues, weight gain, and many other symptoms appeared just as often in people taking a placebo. Only a few side effects showed any link to statins — and even those were rare.
Scientists at Michigan State University have uncovered the molecular “switch” that powers sperm for their final, high-speed dash toward an egg. By tracking how sperm use glucose as fuel, the team discovered how dormant cells suddenly flip into overdrive, burning energy in a carefully controlled, multi-step process. A key enzyme, aldolase, helps convert sugar into the burst of power needed for fert
Scientists are launching an ambitious global effort to map the “human exposome” — the lifelong mix of environmental and chemical exposures that drive most diseases. Backed by new partnerships with governments, UNESCO, and international science advisory bodies, the initiative is rapidly expanding across continents. Powered by AI and advanced data tools, the movement seeks to shift medicine beyond g
A global study has uncovered a mysterious group of gut bacteria that shows up again and again in healthy people. Known as CAG-170, these microbes were found at lower levels in people with a range of chronic diseases. Genetic clues suggest they help digest food and support the broader gut ecosystem. Researchers say the discovery could reshape how we measure and maintain gut health.
After a day of oral arguments in a packed courtroom, a Boston federal judge did not rule from the bench on a lawsuit from AAP against HHS focused on vaccines.
The FDA has rejected a rare disease therapy from Disc Medicine, an early recipient of a commissioner's voucher from the agency.
Several senior officials are exiting RFK Jr.'s department amid an effort to focus on drug pricing and food issues.
