Now that it appears that the authors have all consented to eventually have both of their STAP cell Nature papers retracted, what’s next for STAP? Who knows, but below is my attempt at a top 10 list of STAP predictions looking ahead. I hope I’m wrong about several of them. 10. No insight will come from Nature on the STAP review or editorial process and there will be no indication from them that anything went wrong at their level.  I predict the journal will …Read More

Why would Obokata and her colleagues agree to retract the STAP letter from Nature, especially after for so long categorically rejecting the idea? I suspect they are under pressure from other …Read More

Recently, some scientists reported in Nature that if you take ordinary cells and soak them in a mild acid solution for 30 minutes, often the cells transformed into the most powerful type of stem cells known to science. These newly incarnated pluripotent or totipotent stem cells, which they termed “STAP” stem cells, reportedly …Read More

The piece is entitled provocatively enough “Global patent war looms with epoch-making discovery of STAP cells“. That’s strong language. The article begins with an equally intense statement: Japanese researcher Haruko Obokata’s recent breakthrough in the creation of pluripotent stem cells in mice is set to trigger an all-out global patent war. Puzzlingly, the …Read More
