Blue food dye heals spinal injuries... and dyes you blue.
Researchers at the University of Rochester Medical Center have found that rats injected with the food dye Brilliant Blue G recover enough from severe spinal injuries to be able to walk with a limp. Rats in a control group that did not receive the injection were permanently paralyzed. Right after a spinal injury, the injured area floods with energy-rich ATP which is supposed to rapidly repair the damaged cells, but it also burns out and kills living neurons in the area. Brilliant Blue G blocks ATP from killing the living cells and from making the injury worse. It also turns the subject blue, but it's better than the alternative. If you happen to be a rat, it might make you cuter. Brilliant Blue G is the dye used in blue M&Ms and Gatorade, which prompted The Onion to say, "If Christopher Reeve were alive today, I'm sure he'd be the first to say, 'Blue M&Ms? Are you fucking kidding me?'"
