ScienceInsider reports on a “legal battle between Ron Fouchier and the Dutch government over the publication of controversial research on the H5N1 avian influenza virus.” According to the news service, “On Friday, Fouchier’s employer, Erasmus MC in Rotterdam, formally appealed a ruling by a Dutch court that the government was within its rights when it put limits on Fouchier’s freedom to publish his work with the virus.” ScienceInsider writes, “The appeal is the latest twist in the long-running saga of two papers showing how a few mutations can make H5N1 more transmissible among mammals.” The news service describes the case and other research organizations’ stances on sensitive studies (Enserink, 11/4).
