Along the rocky floors of the Great Lakes, an invasive mussel has quietly solved a problem that has long challenged both biology and medicine: how to hold fast in a world of moving water. Researchers at the University of Toronto have identified a protein called Dbfp7 in the quagga mussel that achieves underwater adhesion without DOPA, a compound long considered the essential ingredient in biological wet bonding. The discovery suggests that nature has not converged on a single answer to the problem of sticking to wet surfaces, and that organisms we regard as nuisances may carry within them solu
