Tim Hunt, the Nobel Laureate whose sexist comments about female scientists sparked a Twitter firestorm earlier this week, has resigned as honorary professor at University College London. Hunt, 72, helped to discover how cells divide. And he apparently had trouble keeping himself together around women. “Three things happen when they are in the lab,” he told a room full of journalists at a conference in South Korea. “You fall in love with them, they fall in love with you, and when you criticize them they cry.” The response from female researchers was swift. “I am in the office, but I can’t do my science work as I saw a photograph of Tim Hunt and now I’m in love, dammit,” tweeted Sophie Scott, professor of cognitive neuroscience at University College London.
