Every time a tissue grows or renews itself, cells must divide inside an already crowded environment. That creates a fundamental problem that scientists have not fully understood: How does a tightly ...

A landmark October 2026 Nature study finds that female skin heals faster than male skin because estrogen synchronizes stem cell division, generating 50% more repair cells within 48 hours of injury, ...

Scientists have discovered how estrogen and testosterone influence skin stem cells, revealing why female skin may heal faster ...

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 ...

Cell division is one of the most fundamental and complex processes underpinning life. In human cells, thousands of molecules coordinate with one another in highly precise steps, all within a fraction ...

This article predates the current owners of Science Blog. It has not been reviewed under the current editorial process and is kept as part of the archive. A simulated cell in the early stages of ...

University of Virginia School of Medicine scientists have revealed how mistakes in the final step of cell division can have dire consequences for developing brain cells. The findings offer important ...

A previously unknown protein, hidden in RNA thought not to encode proteins, helps cells divide correctly. The RNA molecule that encodes the protein also has a function of its own in cell division. The ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...
