All cells need to sense and respond to their environment—to know when to activate genes, build proteins and carry out their basic functions. One of the most well-studied cellular responses is how they ...

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

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 ...

Cells that are about to die send a signal to an executioner protein, but sometimes, those cells can fight back and regenerate ...

Cells in the body have to move around in order to do their jobs. During development, for instance, cells are distributed to create and grow tissue. And in the event of an immune response, different ...

During brain development, neurons extend long processes called axons. Axons link different areas of the brain and carry signals within it and to the rest of the body. Growing axons "wire up" the brain ...

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

A single damaged protein inside one brain cell may seem insignificant. Yet new research shows how that small mistake can ...
