January 4 – Symposium S3: Playing with Power: Mechanisms of Energy Flow in Organismal Movement

Across multiple evolutionary clades and size scales, organismal movement requires controlling the flow of energy through the body to enhance a variety of functions. Whether energy is released or absorbed by the organism, proper function hinges on the ability to finely manipulate both where and when energy is transferred. This symposium comes after a surge in research in power amplification mechanisms over the last decade, and more recently research has expanded into the burgeoning field of power attenuation mechanisms. In this symposium, we have speakers that demonstrate the diversity of mechanisms used to control the flow of energy through the body in order to facilitate fresh perspectives on the unifying mechanical themes of energy transfer in organismal movement. Our speakers cover multiple disciplines including animal biology, cell biology, mechanical engineering, applied mathematics, evolution, and paleorobotics. This symposium brings together this diverse set of people and their ideas to address the challenge of understanding movement in the context of energy flow in multiple organisms.
