Yes, these were imaged live!

Very lucky to be at UCSF with such great microscopy facilities. These instruments are definitely pushing the limits of what we thought feasible in live imaging! Excited to keep exploring how these single cells organize and secrete such precise morphologies.

Preprint alert! I’m publishing my last paper from my postdoc work on archaeal cell biology, with @mullinslab.bsky.social, @archaellum.bsky.social, @samjlord.bsky.social, @marleenvw.bsky.social, @arghya93.bsky.social, and more great folks (thread below with more details)

Great to work with this wonderful team and see this published! Stay tuned for more fun insights live imaging can tell us about scale growth!

Could you add me too, please?

This is the plate that made me fall in love with the genus. Just going crazy exploring morphospace. Working my way through collecting them.

These are becoming more common in the trade. They grow pretty quickly, so easy to propagate/disperse to friends/HEBs. Very charismatic guys! Philodendron are an addiction.

My current project is to understand the evolution and cell biology of the structural coloration within this group. Would be great to chat if you know of good spots to collect Eumaeini/rearing tips.

And here is a Callophrys augustinus probing an inflorescence to lay an egg.
