from dailymail.co.uk: Sushi that glows in the dark has become the latest must try food craze across America. Inspired by genetically modified fish first bred for scientific research, a video showing how to make the glowing sushi has become a huge hit online. The recipes use glofish, a brand of genetically modified (GM) fluorescent zebrafish sold by Yorktown Technologies, which are available to buy in pet shops. The modified fish were originally bred to help detect environmental pollutants. By adding a natural fluorescence gene to the fish, scientists planned to create fish that glowed when rivers became contaminated. First researchers perfected a fish that constantly glowed, which was then bred and sold in pet shops. The fish are available in a choice of bizarre colours - Starfire Red, Electric Green, Sunburst Orange, Cosmic Blue and Galactic Purple. Now, they have become the latest must-try cooking ingredient. However, not all of the US can enjoy them - the fish are currently illegal in California due to a regulation that restricts all genetically modified fish. For the even more adventurous food fan, the team is also working on recipes for cooking glowing mice, created using the same techniques.
