Researchers at Harvard University have developed a new method for setting the brain aglow in a rainbow of colors. ᔥ

“For years, scientists have used fluorescent proteins derived from jellyfish to mark specific cells in genetically engineered animals. But the limited number of available colors wasn’t enough to create a detailed picture of the millions of neurons in the brain. Jean Livet, Jeff Lichtman, and their collaborators at Harvard genetically engineered mice to carry numerous copies of genes that code for fluorescent proteins of three different colors–yellow, red, and cyan–as well as an enzyme that can randomly block any subset of these genes from producing their fluorescent tag. ”
