As this year's Nobel laureates were inundated with congratulations online, the few researchers who correctly guessed the winners also earned themselves a little kudos. For example, Kate Jeffery, a neuroscientist at University College London, correctly foretold on Twitter that her colleague John O'Keefe would win the Nobel Prize in Physiology or Medicine for work on the brain's positional system.

In an interview, Jeffery said that she wasn't just making a casual prediction, but was actively rooting for her former postdoc adviser. She also had reason to celebrate the other two winners, May-Britt Moser and Edvard Moser of the Kavli Institute for Systems Neuroscience in Norway. As a PhD student, Jeffery worked in the same lab as the Mosers when they were postdocs. “It really has been a delight to see a Nobel-prizewinning discovery unfold from start to finish,” she said.
