A newly identified enzyme called IDOL could become a major new target in the fight against Alzheimer's disease. Researchers found that removing it from neurons sharply reduced amyloid plaques and improved key brain processes linked to resilience and ...

Scientists in Canada have discovered that ancient underground rocks are naturally producing hydrogen gas -- and lots of it. Measurements from mine boreholes in Ontario show the gas can flow continuously for years, offering a potential new source of . ...

Researchers have developed a light-driven method for creating tiny, high-energy "housane" molecules that are valuable for drug development and materials science. These compact ring-shaped structures are difficult to produce because of the intense ...

Astronomers have uncovered a strange magnetic "flip" hidden inside the Milky Way. Using a new radio telescope, researchers mapped the galaxy's magnetic field in unprecedented detail and discovered that a mysterious reversal in the Sagittarius Arm ...

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. ...

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 ...

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 ...

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 . ...

Low vitamin D levels could be quietly making breast cancer surgery recovery far more painful. In a new study, patients deficient in vitamin D were three times more likely to experience moderate to severe pain after mastectomy surgery and ended up ...

Scientists have uncovered an astonishing new chapter in humpback whale migration: two whales were found to have traveled between breeding grounds in Australia and Brazil, crossing more than 14,000 kilometers of open ocean. One whale shattered records ...
