That is, our desire to live and raise children in sterile environments provides us little to no exposure to the bacteria and microbes our immune systems need to fight in order to later attack more serious diseases. Other causes include a more sedentary lifestyle, less time spent outdoors, and air pollution.

Republican presidential candidate John McCain added the rise of autism to the political issues he's bringing up on the campaign trail.

One company is being sued in federal court.
The Federal Trade Commission suggests a "healthy dose of skepticism" when considering purchasing a genetic test.
