Fifteen scientists at the Great Lakes Water Institute have a $2 million grant from the Pentagon, with another million awaiting congressional approval.
Their research involves fireflies and zebra fish embryos. They will inject the tiny eggs with genes from fireflies.
The gene-enhanced zebra fish have a glow that's visible under high-powered microscopes when they react to chemicals accumulated in their systems.
It could eventually help the government with early detection of biological or chemical contamination in the water supply.
