🌟 Our first paper! 🌟

@octoscience.bsky.social has created a complete pipeline that makes tracking weird and wonderful animals a breeze, and we've had a blast testing it on our wriggly worms. Check out this thread to see it in action 👇

#OCTRON
Do you love quantifying animal behavior as much as we do? We have just the tool for you! Presenting #OCTRON - a pipeline that helps you create rich annotation data and enables training of custom segmentation models. Have a look, particularly if you work with non-model / invertebrate organisms!

Nature's "blue" isn't pigment — it's physics.

At the #Stowers25 Symposium,
@mblscience.bsky.social Director Nipam Patel showed how butterflies use nanostructured scales to refract light into brilliant colors. 🦋🌈

A bit late but a paper from our lab has been published!
Human fingertip regeneration is a fact, it happens in children and adults (not only in children as it has been long believed). We describe here the regenerative phases and analyse the proteome of wound exudates.

Have you ever wondered how new DNA methylation patterns are established?

Paradigm shift ahead! We discovered a new mode of DNA methylation targeting in plants that relies on transcription factors and sequence motifs rather than chromatin modifications to regulate the methylome. rdcu.be/eQ6L5
