🔬🔦In our latest Imaging spotlight, @jclandoni.bsky.social takes us through his recent papers dissecting mitochondria organisation. Juan discusses why they needed to employ multiple imaging approaches to unveil events that had not previously been observed. focalplane.biologists.com/2026/07/21/p...

FINALLY a histogram in napari! ♥️

napari@napari.org · 3w ago

*Finally*, napari gets a built-in histogram! It's still a work in progress but already *very* cool if we do say so ourselves, with live update based on the canvas and progressive, background update when computing on large full data.

Our kind of fireworks: fruit fly neurons stacked in a rapid succession of rainbow colors. This video shows a small sampling of the more than 135,000 neurons in a typical fruit fly's brain, imaged by researchers at our Janelia Research Campus using multicolor flipout technique 🎆

These stunning single-celled organisms can shape-shift & regenerate. Their trumpet-like shape inspired their name: stentor, after the herald in Greek mythology known for his booming voice. 📸: Confocal microscopy by Igor Siwanowicz, HHMI’s Janelia Research Campus

The once-obscure Danionella fish takes center stage as a model research organism in a major new project funded by the Howard Hughes Medical Institute. Learn more: https://scim.ag/3QFj4XM

One of the world's leading brain research centers is shifting away from fruit flies and toward a tiny, transparent fish. The goal: to understand how brains control the behavior of an animal or human. n.pr/4vV8dYM

Is a transparent fish the future of brain science? This center is betting on it

Janelia is built for this moment. Starting today, we're taking on 2 big bets: cracking how a vertebrate brain generates behavior, & building AI-in-the-Loop Discovery — a new way of doing biology. Tiny transparent fish + one of neuroscience’s biggest questions? Let's go: hhmi.news/2BigBets

And so it begins! Day 1, Lecture 0 of the first DL for Microscopy Image Analysis course at @hhmijanelia.bsky.social. Slides from @florianjug.bsky.social, presented by our TA Federico Carrara. #dljanelia

Home microscope project - high NA Phase contrast with the fun Lowa objective Lomo inverted with the Lomo 1.25 NA water inversion phase contrast Need to add light source and camera and phase annulus

📢 We're recruiting AI Scientists at HHMI Janelia. I'm biased, but these are exceptional opportunities. You'd join as an independent scientist with access to excellent computational infrastructure, some of the best biological data in the world, and a vibrant collaborative environment.

This mesmerizing timelapse captures the nonstop motion inside an animal cell. Red/orange streaks are the growing ends of microtubules, tiny “highways” that can rapidly assemble and disassemble to move proteins & other molecules within the cell. 📸: Andy Moore, HHMI’s Janelia Research Campus

My first corresponding author 🔬🎸🦾 rupress.org/jcb/article/... Ever wonder what the ultrastructure of dopaminergic neuron presynaptic sites looks like? Using cryo-CLEM/ET we observed the wild changes that happen at these sites when the neurons fire or are more quiet. In the latest @jcb.org

Super Res Sunday! And we are doing all the techniques:)

Hari Shroff giving the QI keynote on structural illumination microscopy, adaptive optics and new biosensors. Wow!

Light sheet lab. We image anything from cells to plants to shrimp. @fedegasparoli.bsky.social @excitedemissions.bsky.social are running the machines!

Light Sheet Saturday is here. @jencwaters.bsky.social and @talley.codes lecture on how to improve your photon budget by illuminating from the side.

AI for image analysis. @florianjug.bsky.social @bethcimini.bsky.social @damiandn.bsky.social are showing off the power of the machines:)

Pizza and image analysis. Because there’s no hackin‘ without snackin‘. @damiandn.bsky.social @bethcimini.bsky.social
