Researchers have invented a new form of secret messaging using bacteria that make glowing proteins only under certain conditions. (sciencemag.org)
The Janelia technique is similar to one that Zeng and her colleagues developed using a line of mice genetically engineered so that a certain drug activates glowing proteins in a handful of their neurons. (scientificamerican.com)
The team had also inserted a green glowing protein into the mice that lights up cells during autophagy. (sciencemag.org)
