Researchers have developed a light-induced chemical reaction that visualizes RNA in live zebrafish embryos without interfering with cell processes. In previous work, the team applied the method to cells in culture. But now the researchers have developed the method as the first technique for detecting specific strings of nucleic acids in live vertebrates that doesn’t require genetically modifying the organisms. What’s more, the method is sensitive enough to visualize the expression of microRNAs, which are . . .
