Always a blast to teach the @FIRbees the magic of Drosophila reproduction! and a great reunion with @WolfnerLab 🪰💓🪰
Today is the final day of lab for FIR 2024 and we finished up with a full day of flies 🪰🪰🪰@MBLScience #FIRbees

🧵Excited to share my first author preprint detailing much of my dissertation work! Here we used gene editing to retrace the horizontal transfer of a bacterial gene that now encodes an anti-parasitoid toxin in Drosophila: https://t.co/KRKvzCIewb /1

Immune systems are among the most dynamically evolving traits across the tree of life, and long-lived macroparasites play an outsized role in shaping animal immunity. Even without adaptive immunity,...

NEW Publication: The promise and pitfalls of synteny in phylogenomics in @PLOSBiology!!😄 Synteny—conserved genetic collinearity—is a (re)emerging marker for reconstructing the tree of life. Here, we outline the promise and potential pitfalls of synteny for phylogenetic inference

NEW preprint: #PhyKIT is a command-line tool for analyzing multiple sequence alignments and phylogenies. Here, we detail #protocols for using PhyKIT to build #phylogenomic supermatrices, quantifying biases/#errors therein, identifying putative radiations & so much more.

Female flies exhibit a reduction in mating behavior upon starvation. In this study, Sun et al. identify a neural pathway that responds to starvation via Akh-AkhR/OA signaling. This pathway acts on...

Female fruit flies can interrogate the pheromones of their mates to decide how long they will store sperm after mating and when it’s worth re-mating. https://t.co/6BFGw1ifIY

Five Findlay Lab undergraduates (and their PI) are on the way to #TAGC24, but you’ll have to wait til Saturday night for our posters (876 and 878). We’re looking forward to sharing data on cross-species fertility rescue experiments and regulatory evolution of novel genes!

#TAGC24 ! Have you ever wondered how stem cells give their daughters everything they need to replace their mothers - but keep them from doing so until necessary? Come by my talk during Friday afternoon’s Dev Genetics session to chat all about it.
