New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of cells. By systematically ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients ...

Measuring membrane thickness was previously only possible in artificial membranes—now scientists can do it inside intact cells, providing crucial context for understanding how cells work.

Biologists have long treated the cell as a chemical factory, but a new wave of research is forcing a rethink of that familiar picture. Instead of just tiny bags of reacting molecules, our cells appear ...

Precision and timing of gene expression is essential for normal biological functions and, when disrupted, can lead to many human diseases, including cancers. However, how molecular machines—protein ...

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 ...
