We have made a user-friendly python package `envisionboxbio-apetrack` that combines several tools (Owlv2, ByteTrack, OpenApePose) to track multiple apes without any labeling or finetuning. Check it out: `pip install envisionboxbio-apetrack` github.com/WimPouw/envi...

Some days I think about how we’ve been carefully developing and validating metacheck for two years now, with limited and always-optional local LLM use, and worry it’s just going to be lumped in with quickly vibe-coded AI agents.

I enjoyed writing this piece for The Transmitter. AI is a seismic change for science. What we make of it is up to us, but it’s a decision we can only make collectively. I hope more labs, and the field at large, will engage in finding a shared view of how we want to use AI.

Does it matter whether you use focal sampling or scan sampling to collect animal behaviour data? We used simulations to find out, testing how accurate and precise each method is across a range of behaviours, study systems, and observation protocols.
Illustration comparing which subset of the true occurences of behaviour is recorded using focals vs. scans.
