Viral invasions would make for a good plot in the next Spielberg blockbuster, but according to Michigan State University water researchers, it’s not a Hollywood fantasy. In fact, millions of tiny, dangerous microbes have been attacking native species in the Great Lakes for decades.

These pathogens are hitching rides in ballast water – the water in the hulls of large ships that help stabilize them when on the move – which is then released into new environments when the ships dock at their destinations, according to Joan Rose, Homer Nowlin Endowed Chair in Water Research at MSU.
