Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might behav...
When scientists repeatedly drove a strongly interacting quantum system with laser “kicks,” they expected it to heat up and grow chaotic. Instead, the atoms abruptly stopped absorbing energy and locked...
A brief, intense workout may do more than boost fitness—it could help fight cancer. Researchers found that just 10 minutes of hard exercise releases molecules into the bloodstream that switch on DNA r...
A large review of studies suggests that exercise can ease depression about as effectively as psychological therapy. Compared with antidepressants, exercise showed similar benefits, though the evidence...
Exercise doesn’t just challenge the body; it challenges how the brain interprets effort. Scientists discovered that vibrating tendons before cycling allowed people to push harder without feeling like ...
Scientists have detected a surprisingly hot galaxy cluster dating back to the universe’s infancy. The cluster formed far earlier and burned far hotter than current models predict. Researchers believe ...
Europa’s buried ocean has made it one of the most exciting places to search for life beyond Earth. However, new calculations suggest its seafloor may be calm, cold, and largely inactive, with little e...
Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold gas of atoms confined to a single line, countless collisions occur—but nothi...
Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly reflecting shapes to tile a surface, researchers uncovered a method that links ge...
Around the bright star Fomalhaut, astronomers spotted glowing clouds of debris left behind by colossal collisions between large space rocks. One of these clouds was even mistaken for a planet before s...
Bariatric surgery far outperformed GLP-1 weight loss drugs in a new real-world comparison of more than 50,000 patients. Two years after treatment, surgery patients lost about 58 pounds on average, whi...
Researchers in Japan built a miniature human brain circuit using fused stem-cell–derived organoids, allowing them to watch the thalamus and cortex interact in real time. They found that the thalamus p...
