Inserting monkey and jellyfish genes into cats has given scientists clues about how we could use genetics to fight HIV/AIDS, and caused the cats to glow bright green.
Scientists inserted a gene from monkeys that fights viruses and a fluorescent gene from jellyfish into feline eggs.
The gene from rhesus macaques allowed the cats to fight the feline form of HIV, staving off AIDS. The glowing cells from the jellyfish made it easier to identify the new cells formed by the process of genetic modification.
