Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough "phonon laser" that manipulates tiny vibrations at the quantum level. By dramatically reducing noise in these systems, researchers can now measure motion . ...

Perovskite crystals can dramatically and reversibly change shape when hit with light, a behavior not seen in conventional semiconductors. This effect, called photostriction, can be finely tuned depending on the light's intensity and color. ...

A breakthrough urine test could dramatically speed up how doctors treat urinary tract infections, identifying the right antibiotic in under six hours instead of waiting days. By testing directly from urine--skipping the usual lab culturing step--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 ...

A dramatic surge in kratom-related poison center calls is raising alarm among health experts, as new data shows cases have jumped more than 1,200% over the past decade. Alongside the spike, hospitalizations and deaths linked to the widely available . ...

A new study suggests that simplifying your diet by eating the same meals and keeping your calorie intake consistent could help you lose more weight. Researchers found that people who followed predictable eating routines during a 12-week program lost ...

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 ...
