Scientists discover how aging alters the function of cells, called mesenchymal drift, and manage to reverse this process.

Researchers are learning how to refill the energy reserves of aging human cells, turning a long-standing metaphor about “cellular batteries” into a literal engineering challenge. By training healthy ...

Millions of people live with atrial fibrillation, a racing, uneven heartbeat that can leave you exhausted and scared. Yet it has been at least 30 years since a new drug for this common rhythm problem ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

When a rhinovirus, the most frequent cause of the common cold, infects the lining of our nasal passages, our cells work together to fight the virus by triggering an arsenal of antiviral defenses. In a ...
