Analysis performed on sexual behavior of quails showed that eliminating the stimuli, contrary of what was expected, increased the behavior. The research analyzed conduct learning using exercises which link stimuli to responses (just as human beings understand that turning a key opens a door), and emphasizing of the effects produced when stimuli are suspended.

How could these animals move around in spite of their size? This is the question that a group of scientists of different countries tried to answer. Among them was Rodolfo Coria, Independent researcher of CONICET at theInstituteofPaleobiologyand Geology (IIPByG, UNRN).

Worn out bills will now have a second useful life. They may be turned into material which would help decontaminate wastewater and remove pollutants from the environment. When a bill deteriorates it is destroyed in high speed machines which chop it into small confetti-size pieces. This waste is handled differently in each country; although common practice is to dispose it in sanitary landfills or incineration.

Male Túngara frogs call from puddles to attract females. The production of the call incidentally creates ripples that spread across the water. Researchers at the Smithsonian Tropical Research Institute in Panama revealed that these ripples are used by other male frogs to assess the level of competition in the puddle. Unfortunately for the frogs, their main predator, the frog-eating bat, senses the ripples too, making the frogs easier targets.
