Blue Light Special

For those times when you need to drive from Columbus to Kansas City in a day comes a safety device for the drowsy motorist. Scientists are working on using blue LEDs to keep you awake, as New Scientist reports:
The scientists at Rensselaer Polytechnic Institute, New York, are testing blue LEDs that shine light at particular wavelengths that convince the brain it is morning, they say, resetting the body's natural clock.

That could help reduce the number of accidents that occur when people drive through the night.
Now if we could only find a light that resets the body's bladder during those long drives.
