Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

Innovations in imaging and genetic engineering are coming together to probe the biophysics of cytoplasm inside living animals.

In living cells, regulation of the electrochemical environment is supposed to be managed by ion channels—protein complexes that reside in cell membranes and assume definite shapes. So, it’s surprising ...

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is ...

Cells were long believed to safeguard nuclear contents, releasing them only during cell death. Extracellular DNA was thought ...
