Scientists at the University of Waterloo have uncovered a bold new way to explain how the universe began--one that could reshape our understanding of the Big Bang. Instead of relying on patched-together theories, their approach shows that the ...

Deep sleep does far more than rest the body -- it activates a powerful brain-driven system that controls growth hormone, fueling muscle and bone strength, metabolism, and even mental performance. Scientists have now mapped the neural circuits behind ...

Scientists have discovered something that seems almost impossible: under the right conditions, ordinary liquids can snap apart like solid objects. In experiments, researchers found that when certain liquids are stretched with enough force, they don't ...

Certain smaller sauropods could stand on their hind legs with surprising ease, giving them access to higher food and a defensive edge. Computer simulations show their bones handled stress better than those of their larger relatives. However, as they ...

A major analysis of nearly 10,000 patients shows that simple, non-drug treatments like knee braces, hydrotherapy, and exercise can significantly ease knee osteoarthritis symptoms. These approaches not only reduce pain and improve mobility, but also . ...

Astronomers have spotted a bizarre cosmic explosion that refuses to play by the rules--and it's leaving scientists scrambling for answers. GRB 250702B, detected by NASA's James Webb Space Telescope and a global network of observatories, lasted an ...

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of light-years away. This could explain why some galaxies ...

A large U.S. study reveals that more than a quarter of people with hard-to-treat high blood pressure may have an overlooked hormone problem. Elevated cortisol--often linked to stress--was found in 27% of these patients, far higher than expected. This ...

A powerful cholesterol-lowering drug may be changing the rules of heart disease prevention. Researchers found that evolocumab, typically used for people who already have cardiovascular disease, can significantly cut the risk of first-time heart ...

Just a few minutes of getting out of breath each day could dramatically cut your risk of major diseases--including heart disease, dementia, and diabetes. A large study of nearly 100,000 people found that it's not just how much you move, but how ...
