That's not a tabloid headline, folks... the cute piggies shown below are part of a new genetics experiment, and while they look like perfectly normal pigs in daylight, they also glow in the dark.

According to the L.A. Times this experiment, conducted at South China Agricultural University, is just one of many similar tests around the world in which scientists add a foreign gene to the DNA of a mammal in a process called “active transgenesis.” In these cases, the donor gene comes from a jellyfish that produces a luminescent protein. When it was introduced into the DNA chain of mammal embryos, a portion of the offspring gained the jellyfish's glow-in-the-dark trait.

Bear in mind that as trippy and awesome as this might look, it's actually a practical experiment: transgenesis could soon allow scientists to introduce genes that produce specialized proteins for use in medicines, including the blood-clotting enzymes used to treat patients with hemophilia. The glow created for this particular experiment just shows that the process can work.
 
Other successful experiments have resulted in glow-in-the-dark cats, rabbits and even sheep.
 
[Note: according to a statement from the University, the pigs in the clip below are not being harmed; they're just afraid of the dark. Seriously.]
