Lost for 150,000 years: Rainforest discovery upends human history
For decades, scientists believed ancient humans avoided dense rainforests, treating them as nearly impossible environments for early survival. But a groundbreaking discovery in West Africa is rewriting that story. Researchers uncovered evidence that humans were living deep
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
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
Scientists discover strange link between vitamin D and pain

Breakthrough drug reverses aging in skin and dramatically speeds healing
Scientists have discovered that a topical anti-aging drug called ABT-263 can dramatically improve wound healing in older skin. The treatment works by removing damaged “senescent” cells that accumulate with age and slow the body’s repair process. In aged mice, wounds healed much
AI-driven framework enables precise prediction of RNA splicing and isoform usage
RNA is the means of translating the genetic code embedded in DNA into proteins, which serve as enzymes, transporters, signaling molecules, receptors, structural components, regulators, and gene-expression controllers, among many other roles. Yet one gene is not limited to
We may finally know why dinosaurs like T. rex evolved tiny arms
