Detached sea cucumber tissue survived, healed, and grew for years in natural seawater, revealing a remarkable new model for regeneration and biomedical research. A chance observation has led scientists to a discovery that challenges one of biology’s most basic assumptions: that detached animal tissue eventually dies. Instead, researchers found that tissue removed from a sea […]
Scientists Reveal the Hidden Way Caffeine Sabotages Sleep
EEG studies suggest caffeine can reduce deep, restorative sleep even when sleep duration appears normal. Its effects vary by individual, and relying on caffeine for energy may come at the cost of nighttime recovery. Evening coffee has long been debated. Some people can drink it and fall asleep with no trouble, while others struggle to […]

Your Gut Microbes May Decide How Many Calories You Really Absorb
Researchers have created a model that follows food beyond traditional calorie calculations, incorporating the role of gut microbes in digestion. Food labels make calorie counts look straightforward. The number listed per serving is calculated from the food’s fat, carbohydrate, and protein content. In reality, the digestive process is much more complex. As food moves through […]
Millions Take This Joint Supplement but Scientists Found a Concerning Alzheimer’s Link
Scientists found a concerning Alzheimer’s link involving glucosamine, a joint supplement used by millions. A widely used supplement marketed for joint pain relief may be linked to faster progression of Alzheimer’s disease, according to new research from University of Florida scientists. The study found that people with mild cognitive impairment (MCI) who reported taking glucosamine […]
Scientists Uncover What Kept Humanity’s First Campfires Burning 780,000 Years Ago
Rare charcoal fragments from an ancient lakeshore campsite are offering new clues about fire use, resource management, and the environmental knowledge of some of humanity’s earliest fire users. Long before cities, farms, or written language existed, some of humanity’s ancestors had already discovered a resource that would transform the course of human evolution: fire. But […]

Why Evolution Stalled for Millions of Years Before Suddenly Exploding
A new study suggests evolution stayed stuck for millions of years until sexual reproduction helped unleash a burst of biodiversity. New research suggests that the earliest animals on Earth may have unintentionally slowed the pace of evolution for millions of years. Scientists have found that their reliance on asexual reproduction limited competition and reduced the […]
Breakthrough Ultrasound Patch Tracks Blood Flow and Fetal Health in Real Time
A new soft ultrasound patch is designed to provide long-term, hands-free monitoring of fetal health in real time. Engineers at the University of California, San Diego, have developed a soft, wearable ultrasound patch that can continuously monitor a fetus for hours at a time while maintaining reliable performance even as the fetus and umbilical cord […]
