Human cells are extremely small and tightly packed – at about 20 micrometers across, roughly one-fifth the width of a human ...

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 ...

One of the most well-studied cellular responses is how they react during times of stress, such as when the temperature gets ...

A large genetic screen has revealed how stem cells transform into brain cells, exposing hundreds of genes that make this ...

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 ...

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 found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...
