It feels like it’s been a long time coming in one way as for months now it has felt like retraction was inevitable, but it’s been extraordinarily fast in another way as retractions almost never happen this fast. It’s a day of mixed feelings. This …

Obokata STAP news conference: thoughts, questions & open discussion

Obokata-press-conference

Dr. Haruko Obokata held a news conference today in Japan about the STAP cell controversy. It was very painful to watch. I’m a softy so at moments I felt somewhat sad for her as I watched, but as a scientist I have to say the STAP situation has been very bad for the stem cell …

GFP+-germ-cells

Yesterday was a crazy day for the STAP cell situation. We had RIKEN releasing a scathing internal investigatory report and then some folks in the media got all worked up about a single PCR assay result that Dr. Ken Lee posted on ResearchGate. Some of the reporters/science writers hyped their headlines/articles on this situation as though …
