Researchers from the ecology department in the University of Exeter have been studying how snails transmit a parasite called lungworm to dogs. Needless to say, it's a very slow and boring study.

Except not so much when they attached LEDs to the slugs to track their movements at night. The result you can see in the video is hundreds of snails with both LEDs and UV paint.

While the research may be boring, it is pretty important. Lungworm is potentially fatal to dogs, and it's not clear how they contract lungworm in the first place though it is certain snails are the ones giving them the parasite. [Hungeree via Colossal]
