Scientists Develop Hyper-Sensitive Nanotube Sensors to Detect Toxins


Researchers at Stanford have created a kind of inexpensive sensor based on carbon nanotubes (these things are so useful!) that can detect traces of TNT and the nerve agent Sarin in water. This can be useful to detect terrorist attacks on the water supply or leaching from munition making or storage facilities, but I bet this type of sensor could also be used to detect other kinds of toxins and help us track down polluters.

EPA’s Most Wanted List


The EPA’s most-wanted fugitive list is filled with people who smuggled ozone-depleters, dumped toxins into the water supply, and committed other criminal acts of despoilment (The EPA notes: “Do not attempt to apprehend any of these individuals”). Alas, there are no senior execs from Fortune 100 chemical companies who dump millions of gallons of petroleum into the ocean, or sell carcinogenic pesticides, or manufacture cars that get 0.5 miles to the gallon.
