Serious question… is this is a real fly?
A startup thinks it's a "real uploaded animal". What do you think?

Are Mate Choice and Patch Foraging similar ?! 🧐
We investigated this in a new study, check it out : www.biorxiv.org/content/10.6...
Thank you, Carlos! I am thankful for your mentorship and support throughout this project. It was a joy and a special time to work in the Ribeiro lab and this collaboration!
Alice Augusta Ball (1892–1916) was a pioneering African American chemist who, at 23, developed the first effective, injectable treatment for leprosy (Hansen’s disease) in 1915 while at the University of Hawaiʻi. Her method, which made chaulmoogra oil soluble and injectable, allowed thousands to leave isolation, yet her work was initially stolen by her supervisor, Dr. Arthur Dean.

Congrats Zita, Raquel, Patí, and the whole lab!!
Highly fascinating research on how ovaries control nutritional intake!
Congratulations! Very well deserved!
Thank you very much, Sreeparna!
Thank you, Johannes! Your support and encouragement has been so meaningful throughout, and I’m really grateful for it.
Incredibly happy and grateful to see this story published in @currentbiology.bsky.social! As @hannah-haberkern.bsky.social said, this project is a testament to how collaboration and friendship make the best science. Check out the thread on our paper’s findings. ⬇️
This project started in 2019 with a transatlantic collaboration supported by the @hhmijanelia.bsky.social Visiting Scientist program, continued throughout the pandemic, and even accompanied us to our positions at @uni-wuerzburg.de and @fmiscience.bsky.social.
We also found that optogenetic activation of sugar-sensing neurons did not reproduce the full real-food search pattern: searches lacked the gradual expansion seen after actual feeding. This suggests that real food ingestion and/or post-ingestive signals are key parts of the computation.
Surprisingly, silencing the fly’s head-direction system (EPG neurons) did not disrupt reliable returns to food. So, in this assay, local search does not seem to require the canonical compass/path-integration circuit.
Internal state matters at multiple timescales. Starvation sets the overall search regime, while recent feeding shapes what happens next. In other words, flies appear to integrate a slow metabolic state with fast, meal-linked signals during foraging.
Using long-timescale tracking in a dark open-field assay, we found that fly local search is structured in space and time. After finding food, flies first stay close and make short returns, then gradually expand outward as the trial progresses.
Many studies have shown that hunger plays a significant role in maintaining this balance: the more deprived the animal, the more its behavior is biased toward feeding from the found resource instead of searching for alternatives.
Led by @golddenn.bsky.social and @hannah-haberkern.bsky.social , with Yipei Guo, Shivam Chitnis, Christina Christoforou, @dan-turner-evans.bsky.social, @ribeirocarlitos.bsky.social, Ann M. Hermundstad, and Vivek Jayaraman, we asked how flies balance exploration and exploitation during food search.
