Innovative tech harnesses cyborg mollusks to detect water pollution.

Each "sentinel mollusk" used in a molluSCAN-eye setup provides water quality readings 24 hours a day, 365 days a yearmolluSCANScientists have developed a commercial water-quality monitoring system, molluSCAN-eye, which uses live, electronically enhanced mollusks to detect pollution. Filter-feeding mollusks like oysters and mussels naturally respond to pollutants by altering how they open their shells,...
