Scientists create 'backpack' computers to track small wild animals

Ohio State University researchers have developed a lightweight "high-tech backpack" which can be glued to small animals to track them in hard-to-reach habitats. The wireless network, with functions like motion detection, provided data for a study showing vampire bats developed social bonds in captivity and maintained it in the wild. The team named it "Broadly Applicable Tracking System" or BATS.
