Talk Title: Uncovering the mysteries of insect waste removal: Why and how sharpshooter insects use droplet superpropulsion!
Dr. Elio Challita
Harvard Microbiotics Laboratory
Abstract: Consuming food and eliminating waste are essential processes for all living organisms. While the impact of feeding on animal anatomy and behavior has been extensively researched for over a century, the role of excretion in shaping and limiting animal behavior remains largely unexplored. In this presentation, I will explore how tiny sharpshooter insects, measuring just a few millimeters, efficiently remove their substantial waste by employing droplet superpropulsion – a process that allows them to propel droplets at speeds surpassing the underlying actuator through precise timing. I will also discuss the evolutionary reasons behind their adoption of this unique droplet ejection mechanism, drawing upon energetic and scaling principles.
NOTICE: We will be holding hybrid meetings to accommodate audience members from around the world.
For those able to attend, we will have an informal dinner at 6:00 pm at Cambridge Common Restaurant with the speaker, followed by our formal meeting (~7:30 – 9:00 pm) in room MCZ 101 of the Museum of Comparative Zoology (there will be signs to help direct). The meeting will begin with club announcements, followed by a 60-minute presentation by the invited speaker and Q&A. Membership is open to all.
