Scientists are uncovering why Brazil may be one of the most important yet underused resources for studying extreme longevity. Its highly diverse population harbors millions of genetic variants missing from standard datasets, including rare changes .. ...

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 behave slightly differently at extreme energies. By .. ...

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 into a stable pattern of motion. This strange ...

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 repair and shut down cancer growth signals. When . ...

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 was less certain. Researchers found that light to ...

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 they were working more. Their muscles and hearts . ...

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 supermassive black holes may have rapidly heated . ...

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 energy to support living organisms. Unlike Jupiter ...

Researchers have built a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using atom-thin materials. The light flashes last just femtoseconds and can be used to send encoded messages through open space. The ...

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 nothing slows down. Instead of diffusing like heat in ...
