Scientists develop embryos in space 
Chinese scientists have developed early-stage mouse embryos in space for the first time on a microgravity satellite. Launched on April 6, it carried over 6,000 mouse embryos in a microwave oven-sized self-sufficient chamber. The embryos, put under high-resolution camera, developed from their two-cell stage around 72 hours after launch, a timing largely in line with embryonic development on Earth.
