Thousands of hours of rainforest recordings are helping scientists teach artificial intelligence to recognise Amazonian birds that can be difficult to identify by sound alone. In Colombia, Cornell researchers have been collecting acoustic data from cattle ranches, rubber agroforestry plots and forest to build a clearer picture of which species are using each landscape.

A $12 million research project at Penn State is trying to give drones a new way of making decisions, drawing inspiration from the small brains of insects and other animals. Funded by the US Army's Army Research Laboratory, the project aims to develop an onboard sensing system that can pick out useful information without sending large amounts of data to external computers.

Nearly 400 fossils discovered in southern France are giving scientists a detailed view of marine life that lived close to the South Pole about 470 million years ago. The fossils belong to the newly described Cabrieres Biota, an Early Ordovician fossil site in the Montagne Noire that preserves both hard-bodied animals and delicate soft tissues.

Training a rhesus monkey to sit calmly in one place for a routine health check can be difficult, especially when the animal lives in a busy social group. Removing one monkey from its companions can cause stress and disrupt the group, so researchers tested whether the animals could instead be taught to walk to their own individual station and remain there voluntarily.
