Advocates for research out-numbered animal-rights activists by ten to one at a peaceful demonstration last week at the University of California, Los Angeles (UCLA).

UCLA Pro-Test, a group formed to support scientists who use animals in their studies, rallied about 400 people on 22 April — an estimated 40 animal activists also attended.

Pro-Test was formed by UCLA neuroscientist David Jentsch, whose car was firebombed in March by animal extremists reacting to recent arrests (see Nature 458, 813; 2009).
