More Minnesota med school questions arise - stem cell questions won't die

New Scientist reports:

Lightning never strikes again in the same place? Tell that to the University of Minnesota in Minneapolis, which has launched yet another inquiry into research at its Stem Cell Institute after New Scientist raised further concerns about papers that seem to contain duplicated and manipulated images.

You can read the New Scientist article for more details. But note the ending:

Other stem cell biologists are disturbed that so many problems have been found in papers from a single institution. "It's pretty discouraging," says Arnold Kriegstein of the University of California, San Francisco. Given the pressure on scientists in such competitive fields, he wonders what might emerge at other research centres if their publications were subjected to similarly close scrutiny. "It raises serious issues about how widespread this could be," he says.
