NASA astronaut Jessica Meir works on InSPA-StemCellEX-H2 inside the Life Sciences Glovebox. Microgravity samples will be frozen and returned to Earth for further analysis of stem cell expansion in space. NASA Expedition 74 astronauts aboard the International Space Station are continuing research efforts to manufacture large quantities of stem cellsContinue Reading
Scientists uncovered evidence that human blood cells may trace their origins back to single-celled ancestors that lived 700 million years ago. By rebuilding the evolutionary family tree of blood cells, the team revealed how today’s immune system grew from some of Earth’s earliest life forms., Read MoreContinue Reading
