In a groundbreaking discovery, scientists uncovered the first known structure in complex cells that's capable of drawing nitrogen from the atmosphere and converting it into a form that the cell can ...

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...
