New preprint 🥳! We made photoclickable HaloTag ligands to precisely control protein labeling on living cells. With it, we can do some cool multicolor stuff. Huge congrats to Franzi and all co-authors! Check it out 👇

(1/x) Excited to report VIPS (Volumetric imaging of biological specimens via photochemical sectioning) @science.org! VIPS uses light-based sample sectioning to eliminate the inherent imaging depth limit of high-resolution optical microscopes @supgokul.bsky.social: www.science.org/doi/10.1126/...
Mesoscale volumetric fluorescence imaging at nanoscale resolution by photochemical sectioning
Optical nanoscopy of intact biological specimens has been transformed by recent advancements in hydrogel-based tissue clearing and expansion, enabling the imaging of cellular and subcellular structure...

Halfway to I2K is BACK, friends of all kinds! Last year, 650 people attended 30+ TOTALLY FREE image analysis workshops of all kinds, across many timezones.

If you make image analysis software and want to teach it, workshop submissions are open now! We'd love to have your tool highlighted.
#HappyFluorescenceFriday!

#microscopycommunity- want to learn open source image analysis or share your knowledge to help others? We’ve got a FREE virtual workshop Nov 17-19! Now accepting workshop session applications!

We address a big challenge in synbio: If you give me a protein "X", how can I give you a version of X whose activity is controlled by a kinase?

Our manuscript on accelerating the acquisition rate in oblique plane microscopy (OPM) is online now:

opg.optica.org/boe/fulltext...

Our work addresses the issue that an OPM PSF is tilted, and as such it leaves a lot of "empty space" in Fourier space (FFT of experimental data on the right)... 1/n

New in biorxiv on magnetogenetic design -
"key reaction step involved e- transfer ...to form a triplet spin-correlated radical pair. The magnetic field then controlled the branching ratio between singlet recombination vs. triplet separation."

Mechanism of giant magnetic field effect in fluorescence of mScarlet3, a red fluorescent protein
Several fluorescent proteins, when expressed in E. coli, are sensitive to weak magnetic fields1. We found that mScarlet3 fluorescence in E. coli reversibly decreased by 21% in the presence of a 60 mT ...

I recommend these optomechanics for 'O2-O3' in a single-objective light-sheet (SOLS) microscope:
-> Mechanically and thermally stable.
-> Relatively straightforward to align.
-> 10 popular configurations.
