Networks Cocaine and Fruit Flies

" summary

Group experiments use plexiglass arenas and a CTech flight‑tracker to record 30 adult male Drosophila (3–5 days old) across 20 bottles, comparing regular food versus food laced with cocaine; trajectories are tracked, identities manually validated, and networks built with directed, weighted edges for count and duration. Key findings: duration of interactions increases and interaction count rises after cocaine, while community structure deteriorates — modularity drops. Pipeline is automated (16–20 videos/day), code lives on GitHub, and temporal analysis is ongoing.
