Researchers have uncovered a molecular "switch" that helps explain why exercise keeps ageing muscles healthy. By reducing levels of a gene called DEAF1, physical activity allows older muscles to clear out damage, repair themselves, and maintain ...

Scientists have finally solved a nearly 30-year-old mystery surrounding two unusual molecules found in rye pollen that once showed an intriguing ability to help animals fight tumors. By determining their exact 3D structures, researchers have unlocked ...

Scientists are calling for a lunar quarantine facility where samples from Mars, the Moon, and beyond would be examined before being brought to Earth. They warn that even a tiny alien microorganism could have unpredictable effects on Earth's ...

A new study suggests that apoB, a blood test that measures harmful cholesterol particles, is better than standard LDL cholesterol testing for deciding who needs more intensive treatment. Researchers found it could prevent more heart attacks and ...

A large study found that pregnant women are exposed to dozens of common chemicals, many of which were associated with earlier births and lower birth weights. Researchers also discovered that some replacement chemicals may be just as concerning as the ...

Researchers discovered an "Achilles' heel" shared by E. coli, Shigella, and other diarrhea-causing bacteria: enzymes they use to breach the gut's protective mucus layer. By targeting this common vulnerability, scientists may be able to develop a ...

Researchers have identified a previously overlooked mechanism of brain cell death that appears to play a major role in Alzheimer's disease and frontotemporal dementia. The finding could lead to new treatments aimed at slowing neuron loss by ...

Quantum mechanics has journeyed from a strange and controversial idea to the foundation of some of humanity's most advanced technologies. Now researchers are pushing its boundaries even further, with potential breakthroughs in energy, medicine, ...

Researchers have identified the brain circuitry that links deep sleep with the release of growth hormone, revealing how the two regulate each other. The newly discovered feedback loop helps explain why poor sleep can interfere with growth, muscle ...

Some people live past 100 with remarkable health, and researchers may have uncovered one reason why. A new study found that centenarians have a unique chemical "fingerprint" in their blood that sets them apart from normal aging, including unusual ...
