Quantum physicists learn about Heisenberg’s (publishing) uncertainty principle the hard way

tsfcoverAs Werner Heisenberg famously conjectured, you can’t measure an atomic particle’s momentum and position at the same time. But perhaps the principle named for the German physicist and godfather of quantum mechanics should be applied to another important scientific truth: you can’t publish the same article in two different but competing journals.

Just ask a group led by Ted Sargent, a prominent physicist at the University of Toronto. He and his colleagues recently lost a paper in Thin Solid Films — which sounds like it ought to be the name of an indie movie company, dibs! — on quantum dot solar cells. (If those sound familiar to readers of this blog, there’s a good reason. We wrote about the retraction of another quantum dot paper, this one in Nature Photonics, in October of this year.)

Sargent’s article, “Advances in colloidal quantum dot solar cells: The depleted-heterojunction device,” which he wrote with colleagues in Spain and Switzerland, appeared in August 2011.

“Major errors” lead to retraction of Nature Photonics paper on quantum dots

Maybe it’s an occupational hazard of dealing with quantum physics — uncertainty and all that — but a group of Swiss researchers has retracted their paper on quantum dots after discovering “major errors” that undermined their conclusions.

The article, published in 2010 as a research letter in Nature Photonics, was titled “Polarization-entangled photons produced with high-symmetry site-controlled quantum dots,” by Eli Kapon and colleagues.

FASEB J retracts 15-year-old study after author comes forward, but universities decline to investigate

The FASEB Journal — FASEB stands for the Federation of American Societies for Experimental Biology — is retracting a 15-year-old paper without the consent of all of the authors, despite what seem like valiant attempts to figure out exactly what went wrong.

Here’s the notice for the University of Bern-University of Urbino paper:

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?
