A group of researchers noticed something strange in certain scientific papers involving small rodents (like rats or mice): the number of animals reported at the start of an experiment often did not match the number of animals at the end. This can have a significant impact on experimental results, and yet it turns out to be surprisingly common.
A new paper in PLOS Biology takes a look at the efforts of a team of scientists, led by Ulrich Dirnagl at Charité Universitätsmedizin in Berlin, Germany, to ferret out the many rodents that go missing from lab studies—at least on paper.
