Today has been a dark day of mourning for science following the death by suicide of Dr. Yoshiki Sasai. I did not know Dr. Sasai personally, but was very impressed with his work. His suicide leaves me feeling very sad and it seems like an appropriate time for reflection. (update I did a post on suicides by …

Exactly ten years ago today, on January 29, 2014, I wrote about two new Nature papers on so-called STAP cells. The papers claimed that stress alone could convert regular non-stem cells into some of the most powerful stem cells. More specifically, the authors claimed to make pluripotent stem cells similar to iPS cells this way. …
Once upon a time this blog and major outlets around the world were regularly writing about a Japanese stem cell researcher named Haruko Obokata (小保方 晴子). Whatever happened to Obokata and the other folks directly involved in STAP cell research? First, a bit of background because maybe still a few people never heard of STAP cells …

Remember when the Piero Anversa situation first made news or at least when you first heard about it? In the public domain, it was back around April 2014. I didn’t even do a whole post on it, but rather it made two bullet points in a post about a set of bad overall news including the latest …

Today marks nearing the completion of a full circle for one of science’s biggest controversies: the STAP cell fiasco. Today STAP cells are completely refuted with the publication of two new papers in Nature and we know much more–with some notable gaps still–about what went wrong. STAP cells debunked In January of last year, an …
The Japanese public broadcasting system, NHK, has been accused by scientist Haruko Obokata of violating her human rights. Obokata was the primary researcher involved in the STAP cell fiasco in which two ultimately retracted Nature papers contained duplicated, plagiarized, and manipulated data. She was certainly not the only researcher on those papers, but overall she …

The classic sci-fi movie Fantastic Voyage keeps coming to mind for me as I see and do research involving organoids. In it, the heroes travel inside of the human body in a craft, observing all kinds of awesome biology in an up close and personal kind of way on route into the brain with the goal …

Why do some scientists commit suicide and can such suicides be prevented? Clearly it can be hard or even impossible to tell from the outside what things may be like on the inside for anybody whether they are a scientist or not. Last year the world of science, and in particular the stem cell and …
