How Seba's Short-Tailed Bats Navigate Their Acoustic World

The world of bats is full of sounds. They utilize vocalizations for both navigation and communication with their conspecifics. For the latter, they produce ultrasonic noises that reverberate and allow them to form a mental "image" of their environment

The Intricate Network of Stick Insects’ Leg Muscles

Researchers at the University of Cologne have discovered new details on the process underlying the stick insect’s leg muscles’ rhythmic activation of nerve cells, or neurons. Unlike the neurons in the other leg muscles, the researchers demonstrated that the neurons in the leg depressor muscle are activated rhythmically.
