We use the model insect Drosophila melanogaster to study totes dope hormonal regulation of growth & development, as well as models of neuropsychatric disorders.

Researchers have discovered a cell surface receptor that is essential for adipose #tissue responding properly to #insulin. When the receptor is inactivated, the response to insulin is insufficient. However, a researcher says that it may be possible to stimulate the receptor – thereby protecting against the #development of type 2 #diabetes.

Latest from the lab: What are the mechanism by which insects maintain systemic ion and water balance as they interact with their environment? Another great collaboration with @DenholmLab!annualreviews.org/eprint/FXM…

Let's try this again - look's like twitter can't handle the video 😂. Really excited to share the lab's first Drosophila paper and it's a big one. Check out our preprint shorturl.at/gqrvO where we present the complete neural connectome of an animal circadian clock

Curious about how some beetles have evolved to drink, not with their mouths, but with their rectum? Check out our latest Quick Guide in the current issue of @CurrentBiology. In collaboration with @RobinBeaven @DenholmLab sciencedirect.com/science/ar…

How do animals weigh competing needs to maintain nutrient and fluid balance? Check out our recent review in #BioEssays in which we aim to provide a framework for understanding the polymodal optimization of homeostasis in insects. Also, pretty pictures... onlinelibrary.wiley.com/shar…

Scientists have long known that beetles can survive in extremely dry conditions — thanks to their unusual ability to suck water from the air through their rear ends. Now biologist Kenneth Veland Halberg can explain how and tells Nil Köksal why it matters. cbc.ca/radio/asithappens/bee…
