While our cells are performing some important, basic functions, they can generate compounds known as reactive oxygen species ...

Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

A basic function of cells is that they act in response to their environments. It makes sense, then, that a goal of scientists is to control that process, making cells respond how they want to what ...

Receptors are cellular components that trigger internal changes based on external signals. Researchers have built a new synthetic receptor with incredibly broad potential to program cell activity, ...
