Researchers have developed mice with organs containing human cells, using a convenient and surprising approach — injecting the cells directly into the amniotic fluid of pregnant mice. The method ...

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 ...

There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it ...

Here’s what you’ll learn when you read this story: With more than 100,000 people in need of an organ transplant in the U.S. alone, scientists have turned toward perfecting human-animal chimeras as a ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

When a rhinovirus, the most frequent cause of the common cold, infects the lining of our nasal passages, our cells work ...

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 ...

Stem cells age faster and become functionally exhausted in low Earth orbit, making crewed long-duration space travel even more challenging. When you purchase through links on our site, we may earn an ...

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 ...
