Blinking Bacteria Could Lead to Body-Controlled, Time-Released Drugs

(note - this is a follow-up to a story/video found at http://www.microbeworld.org/index.php?option=com_jlibrary&view=article&id=2545)

What do a bunch of fluorescent, blinking bacteria mean for your health? Surprisingly enough, it's good news. According to PopSci, a new discovery made by scientists at the University of California at San Diego could lead to time-released medications controlled by your body's biological feedback.

Basically, the scientists use a phenomena called quorum sensing to get a colony of E. coli to read the gene for fluorescent dye. During this process, the bacteria exchange small molecules with each other, which regulates conditions and creates a blinking, clock-like effect (see the video after the break). Once this is achieved, scientists can alter factors like pH and temperature, and force the bacteria to react in a certain way at set time intervals.
