This week we have some interesting new reading including both on the stem cell basic and translational fronts as well as on COVID-19 vaccines. COVID-19 vaccine considerations From Derek Lowe at In The Pipeline on COVID-19 vaccine expectations at Science Translational Medicine, Get Ready for False Side Effects. You can read my views on possible

Nature yanks article that was actually advertisement on controversial stem cells

Muse-cell-ad-on-Nature

Something very strange just happened at the journal Nature related to what’s called Muse cells. Kudos to them for dealing with it quickly though. They published an unreviewed research “article” on controversial (perhaps non-existent) stem cells called “Muse cells” that was actually a paid advertisement. After I communicated with the Nature team eventually they ended up

Call for 31 Anversa retractions by Harvard; heart stem cell concept broken?

heart-stem-cells1

In a stunner, Harvard and Brigham & Women’s Hospital reportedly have jointly called for the retraction of 31 papers on heart stem cell research authored by embattled heart stem cell researcher Piero Anversa. The scoop on this by STAT/Retraction Watch written by Ivan Oransky and Adam Marcus gives further details on this mess and past

Science press releases behaving badly: time to start tracking their retractions?

Science-Press-Release-Retraction

Over at RetractionWatch, their team does a great job following retractions of science papers. Sadly, the number of published manuscript retractions gives them more than enough material to post several times a day. There’s another phenomenon going on that I think might warrant their increased attention: the possibly rising number of retractions or corrections of science

Squeeze PR on stem cell paper evokes STAP cell bad vibrations, gets corrected

stem-cell-squeeze

Just how often do press releases (PR) get science wrong? A new paper came out from the lab of Matthias Lutolf in Nature Materials that seems interesting. Using a special matrix, reprogramming of cells reportedly worked better. Good stuff. However, a (PR) from the home institution of EPFL and media pick up on the story used

Could Nature’s 2-year torrent of paper retractions be a good thing?

Nature

The last two years at Nature Magazine have seen a surprising wave of paper retractions. In 2013 and now just so far in 2014, Nature has retracted a total of 14 papers. How unusual is that? Historically, Nature retracts relatively few papers, perhaps just under two per year on average. What the heck has been going on in 2013-2014? Let’s break it

Obokata OKs Retraction of Nature STAP Cell Letter, Not Article

Obokata-press-conference

Japanese news media are reporting that Haruko Obokata and other key authors have agreed to retract the Nature STAP cell letter, but not the Nature article. This is a major development and a peculiar one because to many in the  field it is the Nature STAP cell article that is the more flawed of the two Nature papers on STAP. Why would
