Light Freeze

Scientists are at it again, this time feeding some light sensitive chemicals into transparent worms. Once exposed to ultraviolet light, the chemicals turn blue and the worms will cease to move. A burst of normal light later, the worms are back in action again. What sounded like humans trying their hands at being God actually had more noble intentions.

The scientists hope to be able to develop drugs that can be switched on and off by light for humans. The drugs can be distributed evenly throughout the body and be activated (and deactivated) only at the intended location by shining the light with the appropriate wavelength.

I think I will give this a miracles tag.
