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

For decades, biologists treated DNA as a static string of letters, a linear code that cells read like text on a page. A new ...

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

Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus ...

Cancer isn't just about broken genes—it's about broken architecture. Imagine a city where roads suddenly vanish, cutting off ...

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

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died. He was 97.The ...
