Yes, the same abundant, and entirely free, humidity that makes the summer so unbearable may someday help power the very air conditioning that saves us from the heat.

Pocket EPA: iPhone Gadget to Measure Environmental Hazards

New gizmo will measure local radiation, electromagnetic pollution, and whether or not food is organic.

It's a hazardous world out there. Some things we have control over—like the food we put on our plates—but other risks are harder to detect. Lapka Electronics sees an opportunity in our anxiety over contaminated environments and is soon bringing a device to market that holds some promise to mitigate the toxicity to which we're all exposed.
