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 ...

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 ...

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 ...

Researchers at Oregon Health & Science University have identified a previously unknown system inside cells that works like internal “trade winds,” rapidly carrying essential proteins to the cell’s ...

The story of the princess and the pea evokes an image of a highly sensitive royal young woman so refined, she can sense a pea under a stack of mattresses. When it comes to human biology, it also takes ...

The average human cell contains roughly 10,000 different proteins. Existing as several to millions of copies in each cell, proteins mediate all manner of tasks, including chemical transformations, ...

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 ...

The 2024 Nobel Prize in physiology or medicine has been awarded to US scientists Victor Ambros and Gary Ruvkun for their work on the discovery of microRNA, a molecule that governs how cells in the ...

Tumours have developed many strategies and tricks to gain advantages in the body. Led by cell biology professor Sabine Werner, researchers at ETH Zurich have now discovered another surprising trick ...

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 ...
