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 ...

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of ...

When you think of a chromosome, you might imagine an X-shaped structure. But chromosomes take this shape only during cell division; the rest of the time, they adopt a structure that looks amorphous ...

In two new studies, scientists at Oregon Health & Science University have uncovered detailed blueprints of how certain molecular "gates" in human cells work—findings that could open doors to new ...

Tick-borne encephalitis virus can infect the nervous system and cause life-threatening illness. Finding the cellular gateway it uses could transform prevention and treatment. Read the paper: LRP8 is a ...

A human female is born with all the egg cells she will ever have. The possibility for the development of new oocytes is zero. Given this constraint, it is crucial that these gametes remain healthy and ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants. A study by UT ...

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 ...
