If stretched out, human DNA would be about 2 meters long. For this long strand to fit inside the cell nucleus, which is about ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...

High-resolution imaging has revealed the internal layout of chromatin condensates, showing how DNA fibers fold and interact ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

A closeup look at colibactin’s structure reveals chemical motifs that guide its mutation-wreaking “warheads” to specific stretches of DNA.

Before Watson and Crick basked in Nobel glory, before The Double Helix mythologized their genius, there was the photo. Photo 51 — crisp, clear, and groundbreaking — captured by Dr. Rosalind Franklin, ...

Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable ...
