Step one: very small, immature human eggs within ovarian tissue are placed in culture in the lab, and begin to develop Step two: after initial development, eggs have grown and are more than double ...

We have long believed that brain growth stops and aging begins once we pass the age of 20. However, a study by British ...

In a ground-breaking experiment, researchers have successfully created the first human-monkey chimera. The work, published in the journal Cell, describes the the first embryo containing both human and ...
