Cloning is one of those topics that both fascinates and kind of scares people, especially the idea of duplicating people. I regularly cover the topic here on The Niche because stem cell technologies are involved. Also, one form of the process sometimes called “therapeutic cloning” involves embryonic stem cells. Duplicating mammals has now long been …

The last six months I’ve been spending even more time than usual writing NIH grants (and a few others). The last two weeks have been especially busy on this front as I am getting an R01 renewal out the door. My paper reading lately has been mostly related to the grant writing I’m doing. Still, …
