Today may be a turning point in the STAP stem cell story. Nature itself opened up in a newsy piece about the events that have occurred in the past couple weeks since they published two related papers on acid/other stimulus-induced powerful pluripotent or totipotent stem cells (aka STAP stem cells). Update: Science also published a

I’ve been doing polling on people’s views about STAP stem cells. You can see the week 1 poll results here. I’ve just closed the week 2 polling and the results are above. In week 1 while there was a significant split between respondents, the polling leaned clearly toward people being more positive about STAP stem

Sometimes you think you know a person and they suddenly surprise you by doing something so new that it is shocking or by taking on a new personality. Cells can be that way too. In my book on stem cells, Stem Cells: An Insider’s Guide (you can buy it here on Amazon–it’s very affordable–or also here at

If you’ve been paying attention to the stem cell world, you’ll remember Woo Suk Hwang, who nearly derailed the future of stem cell research by very publically proclaiming that he had made human embryonic stem cells by somatic cell nuclear transfer (SCNT). No, this has nothing to do with Shoukhrat Mitalipov’s report of successful generation
