Going to Cell Bio 2025 in Philly? Join us at the Science and Art session on Sunday! You may know that I love the intersection of art and science. I'll be talking about the art of microscopy 🔬👨‍🎨

Next on the 2026 roster is Dr. Peter Kner, @knerlab.bsky.social. He lectures on wave #optics, #diffraction, and #contrast generation in imaging. This Physics 101 gets everyone on the same #wavelength, even if your background is all biology. Apply now to join us! bit.ly/49YQl7q

#microscopy

On the second day of AQLM, we also have Dr. Steve Ross of #Nikon Instruments who gives us an inside look at #optics, objective #lenses, and #image aberrations. You've (hopefully) never seen an objective like this before!

Apply now to join us April 29th-May 8th 2026. bit.ly/49YQl7q

Day 2 also covers Fourier Optics, with a fantastic lecture from Dr. Peter Kner! You'll never understand Fourier transforms better than you do after Peter explains it, trust us.

Our M.Sc. PBioC (Physical Biology of Cells and Cell Interactions) students at @goetheuni.bsky.social had their first hands-on encounter with STED microscopy this week — and they captured some truly stunning super-resolution images.

#FluorescenceFriday #Superresolution

All #CellBio2025 attendees! Here’s our phenomenal lineup for our session on #SciArt & #SciComm: @ahnaskop.bsky.social, @jiwasa.bsky.social, @mag2art.bsky.social, @nat-prunet.bsky.social, and Julia Licholai. Please come by and spread the word! Huge thanks to @ascbiology.bsky.social and co-organizers!

I’m sure you will!

Love the #SciArt gallery on @maikbischoff.bsky.social's lab website 😍

Studying cochlear neuroanatomy demands imaging the entire cochlea at subcellular resolution. In our recent study (tinyurl.com/isotropicLSFM), we recorded the cochlea at isotropic resolution across the whole organ, laying the groundwork for what follows…

Applications are now open for AQLM 2026! Join us @mblscience.bsky.social April 29th-May 8th, 2026 for a comprehensive, hands-on light microscopy course with an amazing roster of faculty who are leading experts in their fields!

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 !

with Arabidopsis we ensure that the female side of the cross is virgin by emasculating them. Those stamens have to go ✂️

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 😆
