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

Cells rely on tiny molecules called microRNAs to tune which genes are active and when. Cells must carefully control the lifespan of microRNAs to prevent widespread disruption to gene regulation. A new ...

Researchers have shown that the formation of biological condensates affects cellular activity far beyond their immediate vicinity. The results show that they may be a previously missing mechanism by ...

Lipid molecules form the membranes that organize cellular biochemistry in all domains of life. Imaging approaches have been developed to visualize different types of lipid at subcellular scales and ...

Biochemistry and cell biology investigate the molecular underpinnings of life, spanning the structure, function and interplay of biomolecules within cells. At its core, biochemistry elucidates the ...
