Cells rely on tiny molecules called microRNAs to tune which genes are active and when. Cells must carefully control the ...

A new study shows cells use dual RNA signals to control microRNA lifespan. This selective process protects gene regulation ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, ...

Scientists from the National University of Singapore (NUS) have developed a biochemical technique that captures fleeting ...

When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...

A team of researchers has built a new protein sequencing workflow that pairs mirror proteases with deep learning software to ...

In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an important turning point. The so-called plasma membrane lets cells control ...

Angus Chen covers all issues broadly related to cancer including drugs, policy, science, and equity. He joined STAT in 2021 after covering health and science at NPR and NPR affiliate stations. His ...
