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 ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

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 ...

In a spectacular bit of science, a group of scientists has sequenced the DNA from the femur of a man who died 45,000 years ago. The femur they studied is over 20 times older than this 2000 year old ...

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 ...
