You can do that? A massive correction in Nature, but no retraction

This past April, Amparo Acker-Palmer and colleagues published a study in Nature, “Ephrin Bs are essential components of the Reelin pathway to regulate neuronal migration.” Within a day of its publication, Nature readers were raising questions about many of its figures. They started like this:

Andy Gu said:

Looks like Fig 1a, the two middle figures are actually the same with little move from desired regions. I don’t trust their data now…..

After several such comments, Nature senior editor Noah Gray weighed in: Continue reading You can do that? A massive correction in Nature, but no retraction

So how often does medical consensus turn out to be wrong?

In a quote that has become part of medical school orientations everywhere, David Sackett, often referred to as the “father of evidence-based medicine,” once famously said:

Half of what you’ll learn in medical school will be shown to be either dead wrong or out of date within five years of your graduation; the trouble is that nobody can tell you which half–so the most important thing to learn is how to learn on your own.

Sackett, we are fairly sure, was making an intentionally wild estimate when he said “half.” [See note about these strikethroughs at bottom of post.]  But aA fascinating study out today in the Archives of Internal Medicine gives a clue as to the real figuresuggests that he may have been closer than any of us imagined.

Idea retraction: Did Picasso suffer migraines? Do ‘guitar nipple,’ ‘cello scrotum’ exist? Ask pigeons

Cephalalgia published a lovely piece online this month. The abstract is a refreshing bit of honesty:

It is widely believed that Pablo Picasso suffered from migraine. The main cause for this is our suggestion made 10 years ago that some of Picasso’s paintings resemble migraine auras. Here we critically look back at our own hypothesis. We conclude that, although the idea is still fascinating, there is no proof of Picasso suffering from migraine with aura.

In other words, say authors Michel Ferrari and Joost Haan: Go ahead, blame us for this important clinical finding, which we first described in an editorial in Cephalalgia in 2000. We’re retracting the idea, but not before we have some fun with it.

So we figured we’d do the same.

The authors describe a number of famous cases of historical diagnoses such as Hildegard of Bingen, an abbess and mystic of the 12th century whose work has led some to suggest she was a migraneur. It’s difficult to confirm such diagnoses, of course, and the authors draw a parallel to other pronouncements by doctors: Continue reading Idea retraction: Did Picasso suffer migraines?

In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out

 

Last October, Retraction Watch readers will recall, up-and-coming stem cell researcher Amy Wagers retracted a study in Nature describing how her team rejuvenated blood-forming stem cells in older mice. Shane Mayack, a postdoc in Wagers’ lab who had been dismissed after an inquiry into what happened, did not sign that retraction. Since then, Mayack has not spoken to the press, except for a brief comment to Nature through her attorney.

Here, we present, unedited, Mayack’s side of the story. While accepting responsibility, she also has a number of suggestions for how universities and journals can handle these situations better. Shane can be reached at smayck[at]yahoo.com.

Since it was well covered by this blog, the readers of Retraction Watch are no doubt aware that in October 2010, a paper that I co-authored was retracted from Nature and a notice of concern was posted regarding a second paper published in Blood.

So, what went wrong? Continue reading In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out

Salon retracts 2005 Robert F. Kennedy Jr. piece on alleged autism-vaccine link

Salon today retracted a controversial 2005 story by Robert F. Kennedy, Jr. about an alleged link between autism and thimerosal, the mercury-based preservative formerly used in vaccines.

As Salon explains in their retraction notice, the online magazine had co-published the piece with Rolling Stone. The notice reads, in part: Continue reading Salon retracts 2005 Robert F. Kennedy Jr. piece on alleged autism-vaccine link
