Housekeeping
A reader mentioned (thank you!) that last week s edition included at least one paper flagged as open access that actually wasn t. It seems to be the case that Nature Publishing is passing some duff data into the publication metadata food chain, with the result that Unpaywall (we employ the Unpaywall API to identify open access) is repeating this erroneous input to us. This week s edition finds direct links to open access articles from Nature journals still not working, but PDF links appear to be working properly.
