Organelles do NOT have a single uniform pH. And if you think they must, because “protons diffuse fast,” this paper is for you. A thread on why that assumption is wrong; and what we found instead. 🧵 1/n

For an internal talk, I wanted an easy way to disprove the prevailing myth that expansion microscopy gels expand due to repulsion between charged polymer strands. I did a quick calculation of the supposed energy released during a standard experiment and it's equivalent to a small nuclear bomb...

We've now discovered some neat cell culture dishes that feature a 50 micron thick film of a proprietary polymer with refractive index even closer to water than FEP. They work just as well as our homemade FEP assembly and are available in multiwell plate format too! www.sarstedt.com/en/products/...

A new, nerdy paper. We figured out (some) of the rules underlying cell-permeability of probes and designed ligands that light up, grab, and move proteins around. Awesome @hhmijanelia.bsky.social x @uwmadison.bsky.social x @stjuderesearch.bsky.social collaboration! www.pnas.org/doi/10.1073/...

🚨Publication alert🚨 My first, first-author paper is now out in @natphoton.nature.com! Our paper describes an iterative spectral unmixing algorithm and eight-channel camera-based hardware we developed enabling unmixing of low SNR live-cell data at video rates. www.nature.com/articles/s41...

The final version of our multispectral microscopy manuscript is now online at Nature Photonics: www.nature.com/articles/s41... The main additions are some further comparisons to yet more unmixing algorithms, in which we find that our algorithm is still the most accurate.
