Scientists have found that twisting structures in DNA long mistaken for knots are actually something else entirely. Inside cells, DNA gets twisted, copied, and pulled apart. The twists can influence ...

New ultra-detailed imaging exposes the hidden structure and behavior of chromatin condensates — and hints at how their ...

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

Every living thing has DNA, the blueprint for life. These genetic blueprints separate us as species and, further, as individuals. The human genome — the complete set of DNA found in all humans — is ...

Every human face is different, but scientists still know surprisingly little about how our DNA shapes these differences. To learn more, researchers are turning to our ancient relatives, the ...
