Theresearchersused high-speed photography and an instrument called a Rheometer to analyze frog saliva under prey-capturing conditions. The scientists think frog tongues could one day help engineers design reversible soft adhesives that could work at high speeds.

Researchers from Oxford University recently documented capuchin monkeys gleefully banging rocks together - probably to get at minerals inside. The flakes they create look pretty similar to those we’ve attributed to human tool makers.
