Scientists have attempted to map the human cell since the first microscope was invented more than 400 years ago. But many components of the cell still remain uncharted. "We know each of the proteins ...

Researchers are embarking on the RNA equivalent of the Human Genome Project, including sequencing all the chemical ...

A group of researchers has won a large science prize for a discovery not quite two decades in the making. It was long thought that only simple microbes had mastered a chemical conversion reaction that ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

Researchers discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right “tracks” during cell division. Instead of acting like a motor, it works more like ...

A human cell is a Rube Goldberg machine like no other, full of biological chain reactions that make the difference between life and death. Understanding these delicate relationships and how they go ...
