Here's a trick your cat can't do: glow in the dark. Scientists have created cats that glow bright red when they are placed under ultraviolet light, a type of light that can't be seen by humans.
To make the cats glow, South Korean scientists altered the animals' DNA. This chemical contains information about the characteristics of an organism. The scientists added a special gene, of segment of DNA, into the skin cell of a cat. The gene isn't normally found in cats. It causes the animal's skin to produce a compound that glows red in ultraviolet light.
The altered skin cell was added to the reproductive cell of a female cat. When the cat gave birth, all of her kittens contained the gene in their DNA. So the skin of each of the kitties glows in the dark.
