Stem cells age faster and become functionally exhausted in low Earth orbit, making crewed long-duration space travel even more challenging. When you purchase through links on our site, we may earn an ...
New scientific methods could one day render animal studies—the standard in research laboratories for more than 100 ...
Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...
Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...
