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

Now published with peer-review-induced improvements in Biomedical Optics Express: doi.org/10.1364/BOE.579043 We continue to recommend the use of Sarstedt lumox dishes for ease of use and high-quality imaging performance: bsky.app/profile/jame...

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...

🚨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.
