When once-living tissue is preserved in a cold, dry environment, fragments of its DNA can survive for hundreds of thousands of years. In fact, DNA doesn't even have to remain in tissue; we've managed ...

Bronze Age desert dwellers unearthed from graves in what’s now northwest China were buried with cheese scattered on their heads and necks — perhaps as a snack packed for the afterlife. A decade after ...

CpG density and epigenetic modification state modulate DNA mechanics, altering its intrinsic compatibility with nucleosome formation.

Today, sequencing machines can decode up to a hundred million times more DNA than their early predecessors. Where the first ...

Footprints left on a beach. Air breathed in a busy room. Ocean water. Scientists have been able to collect and analyze detailed genetic data from human DNA from all these places, raising thorny ...

Scientists are reporting they have a new way to get genetic information from animals that have long been extinct. They extract DNA from an animal's hair. Using the technique, researchers were able to ...
