Can frogs with foam nests help make biofuels? The long-lasting foam nests of the Túngara frog (Engystomops pustulosus) help protect its tadpoles. Now a team of researchers has designed a novel artificial photosynthesis system suspended in a foam, using the Túngara frog surfactant protein Ranaspumin-2. The system could produce up to 10-fold more biofuel per hectare than plants and could be used on rooftops and nonarable land (Wendell et al. 2010).
