After four wonderful years at the CAES, our lab is moving to TAMU Entomology (@tamuentomology). I am very excited about this new chapter. We will be hiring three postdocs to start early next year. Please contact me if you are interested.

1/8 Breathing seems automatic. But it's a finely tuned motor behavior that has to be controlled. In this preprint, I map the circuits that match a fly's respiration to the metabolic demands of flight and mitigate the risk of dehydration. 🧵🪰 www.biorxiv.org/content/10.6...

We noticed these fruit flies are behaving like tiny big horn sheep of fly world so we went back today to see if I could get some photos of the action. Here you have it, a play in 4 acts! Make me wonder if they evolved the elongated eyes for this purpose. Zygothrica sp. Intag Refugio, Ecuador

Sometimes failed experiments reveal gaps in how we are thinking about a problem, and digging into why an experiment didn't work can lead to discovery. This new preprint by Anne Sustar, in collaboration with Dion Dickman's lab, is one of those gratifying instances.🧵 www.biorxiv.org/content/10.6...

How does the brain control locomotion? In our new preprint, we uncover a brain circuit in Drosophila that controls forward walking independently of turning. This dedicated locomotor circuit enables flexible motor control and might reflect a shared principle across species. doi.org/10.64898/202...
