The human body is a dynamic place. Blood pumps, spinal fluid flows, oxygen comes in and carbon dioxide goes out. Deeper still, charged molecules pass through cell walls, quietly keeping the body's ...

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 ...

Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most animal cells, this process depends closely on properly functioning ...

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 ...

It's been more than two decades since scientists finished sequencing the human genome, providing a comprehensive map of human biology that has since accelerated progress in disease research and ...

There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it takes for cells to behave in desired ways—for example, getting them to produce ...
