Greg Dunn is a neuroscience PhD student at the University of Pennsylvania and a self-taught artist. Inspired by traditional Asian art, he creates gorgeous paintings of neurons. On his website , he says: “It was a fine day when two of my passions came together upon the realization that the elegant forms of neurons (the cells that comprise your brain) can be painted expressively in the Asian sumi-e style. Neurons may be tiny in scale, but they posess the same beauty seen in traditional forms of the medium (trees, flowers, and animals).” The University of California, San Diego Neuroscience department commissioned a series of Dunn’s paintings depicting cortex, retina, hippocampus and Purkinje neurons.

Scientists recorded the sounds that red-bellied piranhas use to communicate with one another and identified three types of vocalizations. The findings are reported in the Journal of Experimental Biology and described in Inside JEB . Authors Sandie Millot, Pierre Vandewalle, and Eric Parmentier from the University of Liege, Belgium, knew that the fish produced some sounds, but did not know why or in what contexts. The researchers recorded the sounds of captive piranhas with a hydrophone (an underwater microphone) while also filming the fish as they interacted. The fish were generally silent and peaceful, cruising around their tank. Vocalizations were only produced during rare confrontations, usually over food. Three distinct types of sounds were recorded.
