A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By electroplating thorium onto steel, they achieved the same results as years of work with delicate crystals -- but far more ...

DNA doesn't just sit still inside our cells -- it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing how genome structure changes from cell to cell . ...

Long COVID affects an estimated 65 million people worldwide and can damage the brain, heart, blood vessels, and immune system long after infection. Researchers now link symptoms to lingering virus, inflammation, micro-clots, and disrupted energy ...

Using NASA's IXPE, astronomers captured an unprecedented view of a white dwarf star actively feeding on material from a companion. The data revealed giant columns of ultra-hot gas shaped by the star's magnetic field and glowing in intense X-rays. ...

Nearly everything in the universe is made of mysterious dark matter and dark energy, yet we can't see either of them directly. Scientists are developing detectors so sensitive they can spot particle interactions that might occur once in years or even ...

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 ...
