<p>Genetically engineered angelfish (Pterophyllum) glow in a tank under a blacklight, at a fish farm in Pingtung, southern Taiwan, September 16, 2010. The fish are the world's first fluorescent angelfish which were created by a joint project between Taiwan?s Academia Sinica and Jy Lin, a private biotechnology company. The breed is the largest fluorescent fish in the world which are able to mate and reproduce, said Yu-Ho Lin, Chairman of Jy Lin. The fish are expected to be sold at around $30 after certification.

Dolly, who born on July 5 1996 after her creation by the Roslin Institute research centre, died in February 2003 after the decision was taken to "euthanase" her when it was discovered she had a progressive lung disease. She has now been preserved for public display at the Museum.  REUTERS/Jeff J Mitchell</p>

<p>Two featherless chickens peck around in some grass May 22, 2002 at the Hebrew University in Rehovot. Israeli scientists at the Agriculture department of the university have genetically engineered bare-skinned chickens as part of a research project to develop succulent, low fat poultry that is environmentally friendly. The naked chicken, as the bird has been dubbed, would also save poultry farmers large amounts of money on ventilation to prevent their chickens from overheating.  REUTERS/Havakuk Levison</p>

The puppy is one of "2nd generation Ruppies", offspring of "Ruppy", the world's first transgenic dog which carries fluorescent genes. They took a fluorescent protein, much like that produced by some sea anenomes, and inserted it into the cell of a beagle. The name "Ruppy" is a combination of the words "Ruby" and "Puppy", and the offsprings of such dogs will possess the same fluorescent gene as their mothers. REUTERS/Jo Yong-Hak</p>

Scientists are genetically modifying a bizarre looking Mexican salamander, which according to ancient mythology is a transformed Aztec god, in the hope its ability to regenerate body parts will one day help human amputees. Also known as "water monsters," the half-foot-long (15-cm-long) axolotl is nearly extinct in its only remaining habitat: the polluted vestiges of Aztec canals that snake though southern Mexico City, packed with colourful boats carrying tourists and mariachi musicians.
