A study by researchers at the University of California Berkeley has found that ethanol is surprisingly common in floral nectar, the sugary fuel that keeps pollinators alive. Yeast feeding on those sugars produces trace amounts of alcohol, and in this study, it showed up in 26 of the 29 plant species sampled.

A small, stingless bee may be able to raise coffee yields while fitting into real-world pest control programs, according to a new study from Brazil. In a field study on full-sun arabica farms, researchers reported a 67% higher fruit yield on coffee branches closer to colonies of the native stingless bee Scaptotrigona depilis, compared with branches farther away. The study was recently published in Frontiers in Bee Science.

These caterpillars use a surprisingly complex rhythm like a secret knock to convince the ants to come fetch them. That's according to research published on February 25 in Annals of the New York Academy of Sciences, which found that caterpillars can keep a beat called double meter that has so far been identified only in a couple of primates.
