A bipartisan set of legislators has called for a comprehensive federal effort to protect the country against aquatic invasive species. The bills introduced last week (H.R. 1592, 1593, and S. 507) would authorize a $25 million research program and an interagency council to coordinate federal activities.

The act would also require that ships treat their ballast water to eliminate unwanted organisms, although how they'll do so isn't clear. Treatments using heat or ultraviolet light are being tested, says James Carlton, a marine invasions ecologist at Williams College in Williamstown, Massachusetts.
