Slutty Mouse Sperms Work In Gangs

Whaddaya got for us today, Science? “Some mouse sperm can discriminate between its brethren and competing sperm from other males, clustering with its closest relatives to swim faster in the race to the egg. But this sort of cooperation appears to be present only in certain promiscuous species, where it affords an individual’s sperm a competitive advantage over that of other males.” I can almost guarantee you that is something you did not know when you woke up this morning.
