A few times a month I do a recommended reads kind of post on more than just stem cells, which people seem to appreciate as a condensed list of new science and medicine. Scientists might ask each other, “what’s in your to-read list?” rather than “what’s in your wallet?” Here are some of the things I’m hoping to get to in coming days or have already taken a look at that seem worth a read. If you want to see last week’s reads here …Read More

Anywhere from about a quarter to half of CRISPR’d embryos exhibited major genome damage. As readers of The Niche know, I never was a fan of the idea of doing CRISPR on human embryos for reproductive use, although I have been supportive of limited, thoughtful in vitro gene-editing studies on human embryos.
