A blue dye found in Gatorade and Rocket Pops could play a protective role in the cellular mayhem that follows spinal cord injury. In rats, a close chemical cousin of the common food dye FD&C Blue No.1 appears to block a molecule that floods the injury site and kills nerve cells, a team reports in the July 28 Proceedings of the National Academy of Sciences.
