Super happy that my cover was featured in nature methods! Zebrafish embryo data were imported, animated and rendered in @sidefx.bsky.social. Congrats to @loicaroyer.bsky.social, @merlinlange.bsky.social and the team for the scientific work! 🧪🔬🐡

I won't talk about NMeth @natmethods.nature.com forever (probably), but I do want to brag a bit about the November focus issue on cell segmentation and tracking, which is many ways is my last hurrah (and final editorial) for the journal. I am so proud of these papers!! www.nature.com/nmeth/volume...

Update I'm back in France 🇫🇷! Joining Inserm to build a multi-omics team on retinal development, at the nexus of live imaging, omics & human embryology.

Huge thanks to CZ Biohub SF folks, esp. my mentor, friend & science soulmate @loicaroyer.bsky.social for the amazing time. More cool science soon🧪

It would be great if VFX artists refused to work with directors who lie and say they don't use VFX.

It would also be fascinating to see how their movies would look if they actually didn't have any VFX.

Illustration done for the first publication of my colleague Nicolas Zucker. He managed to measure heart and breathing rate by monitoring tissue motion in the brain using ultrasound, what a crazy idea ! #sciart 🐡 #scicomm 🧪 #neuroscience 🧠🫀🫁🤯
A non realistic illustration in which some researchers are working around a brain at least 5 times bigger than a human. They are positioning an ultrasound probe on the top to measure heart and breathing rate. We see literally, heart and lungs inside the brain.

Here is a 3D illustration on how ultrasound waves can activate the mechanosensitive RET signalling pathway. A cascade of reaction from the cell membrane to the nucleus. The design was inspired by the interaction of cosmic rays with earth atmosphere 🌍🔬 #sciart 🐡 #scicomm 🧪 @physmedparis.bsky.social

I am creating a list of Information Visualization people. A bit broader than just data visualization, to include people creators of science infographics, charts, graphs, diagrams, explanatory motion graphics, etc. Let me know if you want to be added.
