Scientists studying Bennu samples have discovered that its chemistry is far from uniform. Organic compounds and minerals cluster into three distinct types of regions, each shaped differently by past water activity. This uneven pattern shows that ...

Salt substitutes offer a simple, low-cost way to reduce sodium intake and improve blood pressure, yet very few Americans actually use them--even among those who need them most. A large national analysis spanning nearly two decades found that usage .. ...

Scientists have uncovered a surprising secret about our DNA: it's not a static blueprint, but a constantly shifting, folding structure that helps control how genes turn on and off. Researchers at the Salk Institute found that different parts of the . ...

Drinking coffee at night might come with an unexpected downside: increased impulsivity. In a new study, fruit flies given caffeine after dark behaved more recklessly, ignoring signals that normally make them stop. Daytime caffeine didn't have the ...

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 ...
