Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

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 ...

In many cells of the human body, hair-like protrusions known as cilia act as antennae, allowing cells to receive signals from their environment and other cells. As cells grow and divide, each cilium ...

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 ...

Scientists at Oregon Health & Science University have uncovered a previously unknown system of internal "trade winds" that ...

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 ...
