Glowing prize for Nobel chemists

This year's Nobel Prize in Chemistry rewards the initial discovery of green fluorescent protein from the beautiful jellyfish, Aequorea victoria in 1962 by Osamu Shimomura, now at the Marine Biological Laboratory (MBL), Woods Hole, Massachusetts, Martin Chalfie of Columbia University, New York, and Roger Tsien, of the University of California, San Diego, La Jolla, for their development of GFP as an important tagging tool in the biosciences. DNA technology now allows researchers to connect GFP to interesting, but otherwise invisible, proteins, making them glow green under certain conditions and so providing a way to look deep inside the cell and to develop applications that exploit the fluorescence as a visible marker for specific activity in a range of species from bacteria to pigs.
