There’s never enough time to get all of one’s science reading done, but we can try! It helps to have a list of “to-read” articles, whether actual research articles or media pieces. In the old days, I remember my mentors saying they literally had “piles” of journal articles on their coffee tables, bathrooms, bedrooms, etc. that they needed to read. Here are some past recommended reads. What would be the digital piles of science articles to try to dig into this week? Here are …Read More

Retraction Watch broke the news that Haruko Obokata of the STAP cell train wreck now has a 4th paper retraction. The publication related to the controversial idea that adult tissues have pluripotent potential or actual pluripotent stem cells in them so it was kind of foundational for the debunked STAP cell idea. It also reminds me of VSELs and MUSE cells too, which people to this day still publish about without much attention. There could be some retractions related to VSELs and MUSE cells …Read More

Marilynn and Terry ran the session. The session was …Read More

A paper retraction is a major, painful step in science, but sometimes it is necessary and in the past few weeks we’ve seen news of two high-profile stem cell paper retractions. However, these retractions were handled entirely differently by those involved and were prompted by very distinct situations. Update: for some background on stem cell manuscript retractions more generally see from Retraction Watch here and from this blog here. In the case of a JCI stem cell manuscript retracted by Dieter Egli’s lab, a central problem …Read More
