Sperm Train To Win, Nature Science update
 









Excerpts: Mouse sperm team up to speed their route to
 the egg. New research shows that hundreds of individuals form fast-swimming
 packs to give their genes the best chance against other males' sperm. (...)
 "They're like the carriages of a train," says Moore, who works at the
 University of Sheffield, UK. In the lab, trains can swell to thousands of
 sperm. In female mice they tend to number 50-200 cells.
 Groups travel roughly 50% faster than loners - especially in viscous fluid
 like that in the female reproductive tract.
