In August, Beatriz da Costa, an engineering professor at the University of California at Irvine, will release 20 pigeons fitted with tiny backpacks. Sensors in the packs will measure air pollutants, such as nitrogen oxide--a gas that's released by cars and contributes to smog formation. Cameras attached to the packs will snap photos during the flight, and cell-phone devices will beam the pollution data--along with the birds' locations--back to da Costa.
