Love that cuttlefish bottle 😍

Hey look who's back from firing and will be in the shop Wednesday at 11am Pacific! It's our old friends cuttlefish bottle and hissing possum jar.
Leslielevings.bigcartel.com tomorrow!

Key transcripts encoded centrin-like proteins, a frequent component of sensory/contractile structures in protists. We visualized tentacle ultrastructure by U-ExM with @dudinlab.bsky.social lab, discovering stunning tip and collar structures 🤯that add structural complexity to new tentacle formation.

Cellular structure self-organizes through an interplay between internal mechanisms and external cues. The single-celled suctorian P. collini builds a trap structure to capture large prey using microtubule feeding tentacles, creating feedback between cell morphology and prey availability.

A student-run radio show covered my Nikon Small World honorable mention & I even got to give a radio interview!
A totally new experience for me 😀

Huge thanks to Andrew!

Never seen the death of a ciliate like this-- usually it's too much pressure from the coverslip or too much osmotic pressure. But this gradual posterior-to-anterior "unzipping" effect amazed me !

I was today years old when I learned that *Drosophila husbandry* was actually a skillset to add to a cell/developmental biology resume. I wonder if I should add Arabidopsis husbandry to mine 😆

Hello hello world. I’m on here now. I am a microscope addict. I do a lot of plankton chronophotography, see below video of vorticella feeding currents. I love the microworld and consider myself an advocate for these tiny creatures, I like to make them visible. Will post more soon
