1)All humans have the ability to see ultraviolet light, but it is passively filtered out by the eye’s lens. Patients who undergo surgery to remove the lens can detect ultraviolet light.
2)In 1999, Harvard physicist Lene Hau was able to slow down light to 17 meters per second and in 2001, was able to stop light completely. –
3. Some areas in Scotland and Japan switched to blue street lights at night and saw a decrease in crime and suicide rates. –
4. LED traffic lights have led to car crashes and deaths in the past, since they emit too little heat to melt snow & ice, which blocks the lights.
