New preprint from the lab! We discovered a transient fluidization in the basal region of human forebrains by tracking microdroplets in cerebral organoids.This “basal fluidization”, absent in gorilla and mouse, may contribute to greater surface expansion in human forebrains 1/ doi.org/10.1101/2025...

The connectome of the entire male Drosophila central nervous system is out!! Acquired using FIB-SEM @ 8x8x8nm, we aligned 7.5 mio 2D images aligned into one seamless 3D volume, which was used to segment & proofread neurons and synapses. @hhmijanelia.bsky.social www.biorxiv.org/content/10.1...

Very excited about this project: we believe that 3D anatomical atlases have a huge potential for developmental biology. As a starting point, we made the first ever Drosophila wing disc atlas!

This image shows neurons being grown on a surface with tiny patterns that resemble human tissue to ‘steer’ their growth. Models like this allow us to learn more about our nervous system and conditions like motor neurone disease. Image credit: Cathleen Hagemann and @andreaserio.bsky.social

Building a spine is no joke, but thankfully zebrafish have their own clocks to keep the pace. Excited to share our preprint on the role of biological oscillators in coordinating notochord development! (www.biorxiv.org/content/10.1...) Additional thread below

Priyom's preprint is out on biorxiv. See below for a detailed thread. In a nutshell, she has discovered and characterized the oscillator that times notochord and spine segmentation in zebrafish. Turns out that there are uniform Erk oscillations across the entire tissue that act as timekeepers!
