Nice theory-first call! At @hhmijanelia.bsky.social, theorist, experimentalist, engineers, and computational scientists tightly collaborate. This allows us to integrate all forms of discovery, top-down, bottom-up, middle-out (you pick what's what for you).

“Join the Pigino Lab! We’re hiring a PhD student to explore primary cilia biology using advanced imaging, spatial ‘omics, and AI. Apply now at www.cilia-ai.eu and be part of the Cilia-AI Doctoral Network!”

Nice preprint on SMLM localizations with NN, LUNAR. The network learns both locations and PSFs www.biorxiv.org/content/10.1...

When OMB head Russ Vought talks about deliberate efforts to put federal employees "in trauma" and make them quit their jobs, he's talking about people like Michelle, recently fired by Musk/Trump. www.sfgate.com/california/a...

With the systematic dismantling of science and research funding we see in the US, we in Europe and Germany have a responsibility and a chance to support basic science! Go vote today and make your voice heard! @maxplanck.de @erc.europa.eu @mpinb.mpg.de

Our vote by mail ballot for the German general elections arrived today, less than 24h before delivery deadline (we had applied in December). Anybody taking a flight from IAD to Berlin tonight?

Isotropic, aberration-corrected light sheet microscopy for rapid high-resolution imaging of cleared tissue www.biorxiv.org/content/10.1...

My German election ballot only arrived today, a long shot but is anyone traveling from Boston to Berlin today who could take it? Any leads @germanyinboston.bsky.social ?

Honored to begin as Director @neurobio-upr.bsky.social , UPR Med Sciences. After disasters, pandemic & cuts, we’re rebuilding—expanding into computational neuroscience & ramping up conferences/courses. We’ll seek partners & donors; reach out to join us! Stay tuned for more.

Students and postdocs: interested in theoretical biophysics? Apply for @hhmijanelia.bsky.social’s second Junior Scientist Workshop on Theoretical Biophysics! Applications due in June for a work week of fantastic scientific interactions this October: www.janelia.org/you-janelia/...

Such a fun project and great teamwork with @gaiapigino.bsky.social. Thanks to all involved.

Reminder: The functions of government should be boring. Government is not a reality show and there should be very little day to day drama.

‼️🔬 We start!!! 🎉🤖 Super exciting!!! After years of teaching courses for #DeepLearning for Microscopy and Life Science application, we start today our first “advanced course” @embl.org! #EMBLDeepLearning

If you wanted to cut waste, fraud, and abuse, you would empower the inspectors general. If you wanted more waste, fraud, and abuse, you would fire them.

We read "Large Concept Models" in our reading group. It models language at the sentence resolution - "concepts". We had lots of thoughts about it! You can read them in our new Janelia CVML blog post: janelia-cvml.github.io/blog/posts/L... #ML #AI #Janelia @adjavon.bsky.social @bogovicj.bsky.social

We're looking for a software engineer to work on R/Bioconductor tools for biological data science and AI embl.wd103.myworkdayjobs.com/en-US/EMBL/j...

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. 🧵

After a long journey, Segment Anything for Microscopy is now published in Nature Methods! We significantly improve SAM for interactive and automatic segmentation in light and electron microscopy and build a user-friendly tool. www.nature.com/articles/s41...

The self-driving multiscale microscope from @daetwylerstephan.bsky.social is out. It can image an entire zebrafish embryo longitudinally and follow a volume of interest over time with high resolution. We used it to study cancer-immune cell interactions. www.nature.com/articles/s41...

Can LLMs be used to discover interpretable models of human and animal behavior?🤔 Turns out: yes! Thrilled to share our latest preprint where we used FunSearch to automatically discover symbolic cognitive models of behavior. 1/12

📝 FeatureForest: the power of foundation models, the usability of random forests. Nomen est omen! We use features of the biggest models and train a handy random forest based pixel classifier with them. 👍 Hit bioRxiv recently… check it out! www.biorxiv.org/content/10.1...

ÅNGSTRÖM-RESOLUTION IMAGING OF CELL-SURFACE GLYCANS 🧬🎨🍬 The glycocalyx, our cells' sugar coat, holds secrets in immunology, cancer, viral infections, and more. Visualizing its molecular architecture was impossible… until now. #glycotime #microscopy www.biorxiv.org/content/10.1...

Fun fact: I wrote a 20 page undergraduate paper on Lysenkoism in a class on Soviet Science & Chernobyl. Everybody here should probably look that up if you don't recognize the word.

There's a Korean soap opera on Netflix (When the Stars Gossip) which has *Drosophila courtship in space* as a major plot point (Ep 2). They have Michael Reiser & lab's flight arenas (you can see Janelia & MIchael's initials on the panels). Great way to learn about Drosophila courtship!

We're hiring! Our IT Team is looking for a Linux Systems Engineer to support scientific computing and big data management. Apply here: www.fmi.ch/education-ca...

Trump’s blackout is Orwellian, dangerous, and harmful to all Americans who count on this information for critical services. This censorship is unAmerican.

🎉 Congratulations to our HHMI and @hhmijanelia.bsky.social scientists named to the @cellpress.bsky.social 50 Scientists That Inspire list, which honors scientists whose research and careers drive innovation, cross boundaries, and inspire the leaders of the future. 👏 More: https://buff.ly/40U13Hi

This summer course is going to be awesome! Please repost and tell your students/postdocs/everyone to apply. We have lots of excellent faculty as well as lectures on #connectome modeling by yours truly and Jonathan Pillow.

This from the NSF. Which has championed 'Broader Impacts' for decades. 'Women' is a flagged term. I feel terrible for the POs at the NSF. NSF caving like this wasn't on my bingo card.

I would look pretty differently about any scientist that would volunteer their time to review grants that had to through any of this Orwellian bullshit.

Look at these beautiful new object features, now available in ilastik! Big thanks to Oane @grosoane.bsky.social for bringing them to all our users!

We just released and uploaded a new version of *Mastodon*, the large-scale tracking and track-editing framework for large, multi-view images. Mastodon is available via Fiji, via a dedicated update site. mastodon.readthedocs.io/en/latest/do... Below is a thread that survey some of the novelties ⏬️

Holy shit, nerds, have you seen this? If you're studying #brain wide neuronal activation using #cFOS and a #lightsheet #microscope you need to read this doc STAT🧪🔬. www.nature.com/articles/s41...

Attention evolution afficionados!! A new European Conference of Comparative Neurobiology (ECCN) is coming up in beautiful Alicante (Spain). Join us with a spectacular list of speakers, highlighting our keynotes Gilles Laurent, Alain Chedotal, Laura Fenlon and Henrik Kaessmann.

Folks are always surprised to learn that NVIDIA has been working on a foundation model for cell segmentation called Vista 2D that can be trained on a variety of cell imaging outputs, including brightfield, phase-contrast, fluorescence, confocal, or electron microscopy. Blog in thread 🧵

Employees of the US federal government (full disclosure- including me) today were instructed today to rat out any colleague suspected of covertly engaging in suspected DEIA activities. https://chcoc.gov/sites/default/files/OPM%20Memo%20Initial%20Guidance%20Regarding%20DEIA%20Executive%20Orders.pdf

My lab has a tradition that each week one person contributes edits to a Wikipedia page relevant to their scientific work, and then presents it briefly at lab meeting (and we clap). A few of my favorites: en.wikipedia.org/wiki/Proprio... en.wikipedia.org/wiki/Chionea en.wikipedia.org/wiki/Femoral...

Our paper from Junchol Park and collaborators that has been brewing for a while. Trying to capture our thinking about what action specification in striatum means and what would constitute evidence for such a model. Longer thread soon, but it’s online now. www.cell.com/neuron/fullt...
