For years, scientists have complained that it can take months or even years for a scientific discovery to be published, because of the slowness of peer review. To cut through this problem, researchers in physics and mathematics have long used “preprints” – preliminary versions of their scientific findings published on internet servers for anyone to read. In 2013, similar services were launched for biology, and many scientists now use them. This is traditionally viewed as an example of biology finally catching up with physics, but following a chance discovery in the archives of Cold Spring Harbor Laboratory, Matthew Cobb, a scientist and historian at the University of Manchester, has unearthed a long-forgotten experiment in biology preprints that took place in the 1960s, and has written about them in a study publishing 16 November in the open access journal PLOS Biology.
