The commentary on “Defining Pluripotency in Human Cells” is up at the Niche.

Featuring commentary on their previous article by Peter Andrews, Shinya Yamanaka, Paul Tesar, and William Gunn(aka yours truly).

Stayin’ Alive, a consistently entertaining and thought-provoking blog, has the perfect antidote to an overdose on pluripotent stem cell reporting.

We’re obsessed with a non-existent threat of the Islamofascist movement taking over the world, the moral status of zygotes, the invading brown Mexican hordes who are going to make us all eat tortillas and play giant guitars or something — in the worst case scenario, they might even get driver’s licenses — and how we can cut taxes on investment income.
