In an effort to further study human-genetic disorders, scientists in southern China injected pig embryos with fluorescent jellyfish DNA; when these 10 piglets are put under a black light, they emanate an eerie green glow. This successful integration of genetic material into the animal’s natural makeup, made possible through a technique developed by reproductive scientists at the University of Hawaii, could be instrumental in creating more cost-efficient and effective treatments for disorders like hemophilia.
