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 ...
Researchers say discoveries could expand the CRISPR toolbox and lead to more efficient, rapid diagnostic tools for detecting COVID-19, influenza, and RSV.
