Pigs in space

Topic: Space Sperm Pig China

Well, OK, not entire pigs, or even porcine blastocysts, but rather sperm from Chinese hogs. Couldn't make this stuff up if you tried.

And on a more sober scientific note, why even do this? The article says it's to study "what effect a period of microgravity will have had on the sperm's activity", but I'd be pretty surprised if it has any effect. At the scale of a sperm cell, gravity just isn't a very dominant force.
