Scientists have discovered that even short-term exposure to polluted air can speed up Alzheimer’s, worsening toxic protein buildup in the brain and accelerating memory loss. The research connects fine particulate matter (PM2.5) from sources like smoke and traffic directly to faster cognitive decline. ​Scientists have discovered that even short-term exposure to polluted air can speed …

UC Berkeley researchers mapped the brain circuits that control growth hormone during sleep, uncovering a feedback system where sleep fuels hormone release, and the hormone regulates wakefulness. The discovery helps explain links between poor sleep, obesity, diabetes, and cognitive decline, while opening new paths for treating sleep and metabolic disorders. ​UC Berkeley researchers mapped the …

Scientists discovered seven molecules in the blood linked to excessive daytime sleepiness, a condition that affects one in three Americans and raises the risk of heart disease, obesity, and diabetes. The study highlights the role of both diet and hormones, finding that omega-3 and omega-6 fatty acids may protect against drowsiness, while compounds like tyramine …

Once thought to be sailors’ myths, rogue waves gained credibility after a towering 80-foot wall of water struck the Draupner oil platform in 1995. New research shows that these extreme waves don’t need mysterious forces to form—they emerge when ordinary ocean behaviors like wave alignment and nonlinear stretching converge at the wrong moment. ​Once thought …

Orangutans, humans’ close evolutionary relatives, have developed remarkable strategies to survive in the unpredictable rainforests of Borneo. A Rutgers-led study reveals that these apes balance protein intake and adjust their activity to match food availability, avoiding obesity and metabolic disease. Unlike humans, who often overeat processed foods without adjusting energy use, orangutans switch between fruits, …

Sauropod tooth scratches reveal that some dinosaurs migrated seasonally, others ate a wide variety of plants, and climate strongly shaped their diets. Tanzania’s sand-blasted vegetation left especially heavy wear, offering rare insights into ancient ecosystems. ​Sauropod tooth scratches reveal that some dinosaurs migrated seasonally, others ate a wide variety of plants, and climate strongly shaped …

Some animals don’t age at the same pace, and flamingos may hold the key to why. A decades-long study in France reveals that resident flamingos, which stay put, enjoy early-life advantages but pay later with accelerated aging, while migratory flamingos endure early hardships yet age more slowly. This surprising link between movement and longevity challenges …

Children with higher blood pressure as young as age 7 face a sharply increased risk of dying from cardiovascular disease by their mid-50s, according to a massive decades-long study. Researchers found that even moderately elevated readings, not just full hypertension, raised the danger, with risks climbing as much as 40–50%. ​Children with higher blood pressure …
