Researchers at the University of California, San Diego School of Medicine have created a new generation of fast-acting fluorescent dyes that optically highlight electrical activity in neuronal membranes. The work is published in this week's online Early Edition of the Proceedings of the National Academy of Sciences. The ability to visualize these small, fast-changing voltage differences between the interior and exterior of neurons — known as transmembrane potential — is...

Researchers at the University of California, San Diego "“ led by 2008 Nobel-Prize winner Roger Tsien, PhD "“ have shown that bacterial proteins called phytochromes can be engineered into infrared-fluorescent proteins (IFPs). Because the wavelength of IFPs is able to penetrate tissue, these proteins are suitable for whole-body imaging in small animals. Their findings will be published in the May 8 edition of the journal Science."The development of IFPs may be important for future...
