It’s been a few weeks since news broke that cats are glowing now. They aren’t radioactive feline superheros or anything; instead, the cats glow because scientists infected their embryos with modified viruses that give fluorescent properties. It’s psychedelic proof that certain gene modifications are possible, which is good news for the world of medicine.As cool as neon kitties sound, biologists have found what might as well be their arch nemesis: glowing scorpions. Paul Marek, an entomologist at the University of Arizona, said he found the glowing scorpions while doing regular insect searches at night using a black light. The black light comes in handy because it’s less disruptive in the desert night than a flashlight would be. An added bonus is that the scorpions light up like a velvet poster in your college hippie friend’s ironic dorm room.National Geographic has the scoop:Scientists know why scorpions are fluorescent like this, because of a nitrogenous substance in its cuticles, but what's not known with any certainty is whether there is any purpose behind the fluorescence (other than to make it easy for humans to find them in the dark). "It's a really easy thing to," Marek said. "You go out at night into the Sonoran Desert with one of these UV lights and … these scorpions light up and glow like a little star field on the ground."For a video interview with Marek and some more photos, click through for NatGeo’s story.
