We do an awful lot of looooong video recordings in our lab and have long wanted an easy way to clip, compress and combine videos for our workflows. So here's #croppy! 🦀 I hope others will find it useful too - I'd love to hear if you do! And would appreciate if you give it a star on Github! 🌟

Our postdoc @roald-arboel.com made a thing! #Croppy is #free and awesome for fast and effective #video #editing and it has a #GUI! Need to crop a part of a video? Need to trim a video? Need to combine videos? Need to compress a video? roald-arboel.com/croppy/

🌟 NEW OCTRON RELEASE! 🌟 Want to track your animals using the command line? You can now train models and predict videos with single prompts in a terminal! Ideal for batch jobs, headless servers, and remote machines. Big shout-out to @roald-arboel.com for helping with this release!

Off to the caves! We’re finally back in the field: filming sleepy cave spiders! 🕷️🕸️ Let’s see what we find! #fieldwork #animalsleep #caves @roald-arboel.com @nadjageiger.bsky.social @roesslerdaniela.bsky.social @unibonn.bsky.social

🔥 Our latest work is state of the art 3D pose estimation, with video analysis from a single camera! 🎥 Just train with 3D data, and then only 1 camera is needed! 🖤 Presented this week at #CVPR2026 by lead author Ti Wang! Please repost🩵🙏🏼 xiu-cs.github.io/FMPose3D/ arxiv.org/abs/2602.05755

New paper alert!🕷️✨ Tiny spider. Shiny abdomen. Suspiciously wiggly bum. In our new study, we asked what abdomen bobbing in this jumping spider is really all about: Cute? Yes. Meaningful? Let’s find out...! [1/8] @unibonn.bsky.social link.springer.com/article/10.1007/s00265-026-03745-1

🚨 TWERK ALERT 🚨 New publication from @sleeblab.bsky.social ! This was a very fun project to write up, co-lead by @nadjageiger.bsky.social and Chiara Hirschkorn. If you are interested why these spiders might bob their abdomen: link.springer.com/article/10.1... (Short thread following soon)

1/ New preprint! 🧪With @talmo.bsky.social and team, we used deep learning on archival NASA video of mice on the ISS. Turns out mice in microgravity become tiny acrobats: huddling to sleep, doing backflips, even briefly generating their own ~1g. #SpaceBiology #OpenScience #NASA #SLEAP

New preprint: Whole-body 3D kinematics of freely behaving 𝐷𝑟𝑜𝑠𝑜𝑝ℎ𝑖𝑙𝑎 New tech from @blobology.bsky.social & others at @hhmijanelia.bsky.social, which @ispizua.bsky.social and @elliottabe.bsky.social used to gain insight into 3D structure of locomotion & courtship www.biorxiv.org/content/10.6...

What's something that experts/practitioners in your field universally agree upon, but that remains a "hot take" among the general public?

Have you ever wondered why mice do what they do when they are free to do whatever they want? Check out our latest (and this slightly delayed thread about our recent paper, led by Caleb Weinreb and friends...) www.cell.com/neuron/fullt...

Spontaneous behavior is a succession of self-directed tasks

Weinreb et al. reveal a hierarchy of timescales in mouse behavior, including low-level syllables and high-level behavioral states. States and syllables are encoded in different brain areas. Prefrontal...

We are responding to this call for evidence: ec.europa.eu/info/law/bet... Do you have concrete examples of the added value of #Rstats in the public or private sectors? Include the most important factors (risk, lock-in, security, innovation...) to assess the added value. Thanks!

Does anyone here use or have used EthoVision XT and/or ANY-Maze, and could possibly share some sample data with me? I'm making functions for importing movement data into R, and these are tools that I have yet to cover, but I need some data to help me on! #animalbehaviour #neuroskyence

⚠️ New paper alert and what a way to end 2025! 🎉 Happy to share our story “Sleep-dependent infraslow rhythms are evolutionarily conserved across reptiles and mammals.” published today in Nature Neuroscience. Sleeping dragons 🦎 and functional ultrasound! Read the full paper here: rdcu.be/eWJHb 1/8

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!

About to do a major documentation revamp for an R package. Does anyone know whether it's possible to use Quarto `.qmd` files for vignettes and articles? #rstats

New preprint: Neural manifolds that orchestrate walking and stopping Here we develop a new theory for neural generation of walking and how it can stop- Next we test the theory using Neuropixels probes in the lumber spinal cord of freely moving rats. See more: www.biorxiv.org/content/10.1...

✨ Super stoked to announce that I will soon be joining the #SLEEB-Lab with @roesslerdaniela.bsky.social at @unibonn.bsky.social! Really excited for what’s to come!🕷️💤

Two awesome news for our #SLEEB-Lab @unibonn.bsky.social 1) we finally had a lab photoshoot and 2) I can now officially announce @roald-arboel.com is joining our team as a Postdoc starting in November!!! Sweet tracking stuff ahead. Welcome to the #spider #behavior fam, Mikkel!

Breaking News: Jane Goodall, one of the world’s most revered conservationists, died at 91. Her discoveries in the 1960s about how chimpanzees behaved in the wild broke new ground and represented what was called “one of the Western world’s great scientific achievements.” nyti.ms/42kpGxt

I’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time! www.biorxiv.org/content/10.1...

And we are live! Excited to announce the 2025 Multi-Agent Behavior Challenge on cross-lab supervised action recognition in mice 🐁🐀🖱️ Running on Kaggle until December 15th, with a $50,000 prize pool going to the top five submissions! www.kaggle.com/competitions...
