To learn why biologists are all aglow about a luminous jellyfish molecule called green fluorescent protein (GFP), check out this brief primer from Marc Zimmer of Connecticut College in New London. By allowing scientists to track proteins and cells, GFP has become a lab workhorse. The site, which supplements Zimmer's book on the topic, describes the molecule's structure, introduces the researchers who isolated GFP and pioneered its use, and surveys its applications. This GFP-making mouse (above) allows researchers to observe interactions between tumors and the surrounding tissue.
