Something very strange just happened at the journal Nature related to what’s called Muse cells. Kudos to them for dealing with it quickly though.

Gary Schwitzer, over at Health News Review, is reviewing science PRs, which is really interesting reading. I highly recommend that you check it out. While recent data …Read More
