Cells are not immortal, and that is a good thing. After a certain number of divisions, many human cells stop multiplying for good. They enter a state called replicative senescence, where growth ceases ...

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 ...

Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different ...

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

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 ...

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 ...

Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production ...

Human eggs seem to dispose of their waste more slowly than other cells do, which may help them avoid wear and tear – and explain why they live longer. Every woman is born with a finite number of egg ...
