There was debate about whether they even existed, but it now seems fairly established that there are some of the little guys in there. Just because one of the …

STAP-cell-Obokata-2016

Haruko Obokata is most well-known for her role as first author of the now retracted two STAP cell Nature papers.

Haruko Obokata (小保方 晴子) book is a #1 best seller

Obokata-book-Amazon

Haruko Obokata wrote a book about the STAP cell scandal telling it from her perspective. Fom all accounts I’ve seen, she has sought in her writings to shift the blame away from herself. She even claimed she was framed by other scientists. To say I’m skeptical would be an understatement. Will this book have any …
