DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

What scientists long believed were knots in DNA may actually be persistent twists formed during nanopore analysis, revealing an overlooked mechanism with major implications.

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 ...
