If a paper that has never been cited is retracted, will it be missed?
Japanese researchers have retracted an obscure 1996 article in an equally obscure physics journal after concluding — some 15 years later — that their fundamental assertion was mistaken.
The paper, “Uptake and excretion of cobalt in the crustacean Portunus trituberculatus,” in Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, purported to show that a form of the element cobalt might be helpful in tracing the growth of Portunus trituberculatus, otherwise known as the blue crab.
That’s the world’s most harvested crab species and a particular favorite in Asia. But don’t confuse it with the Chesapeake Bay blue crab, Callinectes sapidus, of William Warner’s Pulitzer Prize-winning book, Beautiful Swimmers.
The problem with such elemental tracers, it seems, is that crabs moult repeatedly, shedding their shells, along with the elements that build up inside them. According to researchers from the Research Institute for Advanced Science and Technology and the Osaka Prefectural Fisheries Experimental Station, however, a volatile form of cobalt, previously undetected, could be a suitable element for tracing the growth of both crabs and prawns — another important aquaculture species in Asia — over time.
But that turned out to be a (shell)fish tale. Per the retraction notice, which appears in the May 15, 2011 issue of the journal: Continue reading Another unofficial record? Authors walk back arcane blue crab paper — 15 years later
