Our new paper showcasing molecular connectomics with pan-expansion microscopy is out in @natbiotech.nature.com! www.nature.com/articles/s41...
This wonderful collaboration with @bewersdorflab.bsky.social was led by Ons M'Saad (now founder/CEO of Panluminate) and @allisonphysics.bsky.social. (1/5)

Happy to share the first paper from my journey at @psich.bsky.social towards X-ray connectomics, now out in @natmethods.nature.com: www.nature.com/articles/s41...

Thank you so much @wellcometrust.bsky.social for supporting us to push the the limits of #X-ray #nanoimaging and #connectomics, and to make technology more broadly available to the scientific community! πŸ™

How astrocytes orchestrate ensembles of neurons?

Congrats Lucas for pushing this work to the finish line!

Published an op-ed for @cnn.com: β€œNobel laureate: I owe America my success. Today, its scientific future is in danger.”
A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world.

We could also offer a solution to the long-standing ring artifacts problem in #tomography.

Thanks to self-supervised image restoration, we could simultaneously improve spatial resolution and accelerate data acquisition. #AI #microscopy

X-ray nanotomography can be your new friend for neuronal imaging. In our new #preprint (tinyurl.com/nanoXneuro) we present advances that push the spatial resolution limit for X-ray holographic nanotomography (XNH). We can now resolve synapses. 🧡
