When a fish sees the world move, it immediately swims with it. This is the optomotor response: a visual reflex found across animals that helps us maintain our position and orientation as our surroundings appear to drift. 🐟👀

Excited to share this work from @darbly.bsky.social's lab and my lab with @davidhildebrand.bsky.social @briandepasquale.bsky.social and many others! It turns out that the sensory neurons that detect CO2 in Aedes aegypti mosquitoes have lots of recurrent connections! 🦟👃🌟

First paper entirely from our lab is out in the wild! We tested if reprogramming still works in the aged CNS and found the aged retina blocks neurogenesis both intrinsically in Müller glia and through exacerbated inflammation. Then point at some ways to overcome this. www.pnas.org/doi/10.1073/...

Preprint for the first manuscript of the Angueyra Lab is out! We delve deep into cell-fate decisions during photoreceptor development and discover that the 𝘵𝘣𝘹2 paralogues play multiple roles to control the fate of the five photoreceptor subtypes in zebrafish.

As we near the end of #EarthWeek, a reminder that #zebrafish do not need sterile dishes! Save money and reduce plastic consumption by sanitizing used dishes with hot water or dilute bleach 🧫💦 For example, you could follow this protocol from the Fish Floor at UCL: www.protocols.io/view/washing... 🐟 🧪

One of our dissection scopes (rescued from another lab) has a knob that's very sticky. Asked Zeiss about disassembly instructions to clean it out and they pointed out that this scope dates to before the fall of the Berlin wall (and no documentation available). So, still working at ~40 years!

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue. The effect presumably comes from the absence of S-cones in the fovea. From Hinnerk Schulz-Hildebrandt: arxiv.org/pdf/2509.115...
