Summary: A group of scientists from Brown University, Central Michigan University, and the Scintillon Institute, have received BRAIN Initiative award from the NSF to develop bioluminescent tools to study the brain.

Caption Four tubes contain the ingredients that produce bioluminescence: Coelenterazine appears buoyant, swirling as it interacts with luciferase. The three tubes on the right also contain different colored fluorescent proteins attached to the luciferase which, as a result, emit cyan, green or yellow light. Credit Nathan Shaner
