We made two factual errors in the final paragraph of the full (website only) version of this News Roundup article by Owen Dyer (28 June). Firstly, we wrongly stated that Professor Nicholas Woodrefused to attend the inquiry in Singapore (that related to Professor Simon Shorvon, who had been dismissed as director of Singapore's National Neuroscience Institute). In fact, he had not been invited to attend, and he cooperated with the inquiries and dealt with the specific questions via email. Secondly, we also said that Professor Wood had worked in Singapore and had now started work at the Institute of Neurology in London, whereas he has been a full time employee of the institute since 1995.
