With @megyounger.bsky.social's lab, et al., we present the first connectomics work in the disease-vector mosquito Aedes aegypti, revealing how its brain is wired to detect host cues.

🚨This is a HUGE escalation and a deliberate effort to use the government against Trump's enemies. Weaponizing the Student and Exchange Visitor Program certification against Harvard to punish them for pushing back is a new low β€” and needlessly punishes thousands of innocent students.

@darbly.bsky.social has been and continues to do amazing work with more limited resources at HMS based on the platform he and @dddavi.bsky.social laid down with Clay Reid. But I think absent those substantial Janelia / other private investments starting 10y ago, we’d be years behind.
