A team of researchers has generated one of the most detailed 3D maps of human chromosomes, cataloging over 140,000 DNA looping interactions.

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to switch genes on and off with exquisite precision. The latest work on ...

For James Watson, DNA was everything — not just his life's work, but the secret of life itself. Over his long and storied career, Watson arguably did more than any other scientist to transform a ...
