Faster-than-light neutrinos are hanging in there, though not everyone believes they really move that fast. Luca Stanco of the National Institute of Nuclear Physics in Italy was doubtful about the initial results but two weeks of further tests have helped ease his mind. "The measurement seems robust," he says. In September, the OPERA team, of which Stanco is a member, announced that the ghostly subatomic particles had travelled the 730 kilometres from the CERN particle accelerator in Switzerland to the Gran Sasso mine in Italy about 60 nanoseconds faster than light speed.
