Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response ...

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 ...

Inside every cell, a cleanup operation runs around the clock. Proteins are constantly damaged by wear and tear. Some can be repaired, while others must be dismantled and recycled. When this system ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...
