Scientists at the Max Planck Institute for Developmental Biology, together with American colleagues, have decoded the genome of the Pristionchus pacificus nematode, thereby gaining insight into the evolution of parasitism.

The good news, if you're grazing normally on algae in the rocky intertidal zone of the North Atlantic, is that you may not be infected by a parasite. But the better news is, according to new research from the University of New Hampshire, that you might have more to eat if plenty of your neighbors are infected.
