The News Feature ‘Physics on two wheels’ ( Nature 535, 338–341; 2016) contained several biographical inaccuracies. Michael Papadopoulos moved his family to the United States more than a decade before taking a job at Oregon, not in 1967. Jim Papadopoulos spent a whole academic year at Oregon before starting at MIT. He did not write to bike companies asking for work until the 1990s. His time at the US Geological Survey was part of an internship, not a full-time job. The e-mail list he moderated was also founded by him, and is called Hardcore Bicycle Science. He has actually published three first-author papers, but just one related to bicycle science. He was also not given a chance to respond to a comment about his ability to finish things.
The News Feature ‘The beer geeks’ ( Nature 535, 484–486; 2016) misattributed the quotes in the last paragraph. They came from Kevin Verstrepen, not Stijn Mertens.
