MIT scientists discover amino acid that helps the gut heal itself
MIT scientists have identified cysteine — an amino acid found in foods like meat, dairy, beans, and nuts — as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping stem cells rebuild damaged intestinal tissue after radiation exposure. Researchers say...
Scientists discover the nutrient that can supercharge cellular energy
Researchers discovered that leucine, a nutrient found in protein-rich foods, can supercharge mitochondria by protecting crucial energy-producing proteins inside cells. The breakthrough uncovers a powerful new link between diet and cellular energy — with possible implications for cancer and metabolic disease treatments.
UNESCO warns a tsunami in the Mediterranean is inevitable
The French Riviera may look like an unlikely place for a tsunami disaster, but scientists warn the threat is far more real than most people realize. Historical events and new modeling show that destructive waves have already struck the Mediterranean coast — and could hit again with very little warning....
A Sticky Solution to a Pesky Agricultural Problem
A water-based formulation developed at the University of Waterloo using nanotechnology is both greener and more effective than conventional methods for delivering agricultural pesticides.
New Beescape Updates Include County-Level Plant Recommendations for Pollinators
Penn State’s Beescape tool is gaining a new feature that allows users to download county-specific lists of pollinator-attractive plants, offering a more localized approach to improving pollinator habitats across Pennsylvania.
A New Study Explains How Carbon Dioxide Cools the Upper Atmosphere—and Warms Earth Below
Even as temperatures rise on Earth’s surface and in the lower atmosphere, the planet’s upper atmosphere has cooled dramatically.
Britain’s 11,000-year-old “oldest northerner” was a 3-year-old girl, DNA reveals
Scientists have identified the oldest known human remains in Northern Britain as a young girl who lived around 11,000 years ago. Found in a Cumbrian cave and nicknamed the “Ossick Lass,” she was likely between 2.5 and 3.5 years old when she died. Nearby jewelry and evidence of multiple burials...
Scientists use DNA from poop to save the world’s rarest marsupial
Scientists in Australia are using cutting-edge DNA techniques to help save one of the world’s rarest marsupials — the critically endangered Gilbert’s potoroo, with fewer than 150 left in the wild. By analyzing tiny traces of DNA in the animals’ scat, researchers uncovered clues about the elusive fungi the potoroos...
T. rex’s tiny arms may have evolved for a surprisingly brutal reason
Why did T. rex have such tiny arms? Scientists now think it’s because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators hunting enormous prey. In other words, once the bite became deadly enough, the...
