Mouse embryo captured growing on video A team of U.S. researchers has used a new microscope to capture the development of a living mouse embryo.

For nearly three days after a sperm meets an egg, the human embryo (a tiny, eight-cell blob) is managed by the egg’s genes. On day three, the embryo strips its entire genome naked, freeing itself of ...
