Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

For the first time, clumps of human cells called organoids were fully integrated with the brains of rats—and influenced their ...

Unlike virtually every other cell in the human body, the syncytiotrophoblast doesn't have a single nucleus. It has roughly 10 ...

When you were first conceived, you were a single cell. From this basic fact, we can extrapolate a few things, most especially that all the cells that make up your body today came (indirectly) from ...

Researchers recently developed a bone marrow model to study how the body generates cells. Interestingly, this model is the first of its kind to be developed entirely from human cells. Not only can ...

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 ...

Biomedical researchers at Texas A&M University may have discovered a way to stop or even reverse the decline of cellular energy production—a finding that could have revolutionary effects across ...

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

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. This undated image provided by the Mitalipov Laboratory at Oregon Health & Science University shows a a microscope image of a ...

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 ...
