With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.
The field of ancient DNA, which combines archaeology and anthropology with cutting-edge genetics, is requiring scientists to have frank conversations about when research is justified and who it benefits.
Researchers found the relatively high proportion of DNA from a hominin cousin—nearly 5 percent—when they scanned more than 1,000 genomes from 118 distinct ethnic groups.
The oldest DNA yet isolated from humans in Africa reveals long-range migrations around 50,000 years ago, which likely played a role in the Middle to Later Stone Age transition.
