Scalable near-real-time Bayesian phylogenetics for outbreaks with Delphy - Nature
Delphy makes near-real-time and scalable Bayesian phylogenetics possible for growing viral outbreaks, enabling public health bodies anywhere to analyse and react to their own data with state-of-the-art accuracy and minimal friction.

In a new (ish) preprint, we used CRISPR barcodes to label germline stem cell clones in zebrafish, then tracked their contributions to sperm production for 2 years. Instead of staying stable, individual clones rose, fell, and disappeared over time. www.biorxiv.org/content/10.6...

Our paper benchmarking foundation models for perturbation effect prediction is finally published 🎉🥳🎉 www.nature.com/articles/s41... We show that none of the available* models outperform simple linear baselines. Since the original preprint, we added more methods, metrics, and prettier figures! 🧵
Beeswarm plot of the prediction error across different methods of double perturbations showing that all methods (scGPT, scFoundation, UCE, scBERT, Geneformer, GEARS, and CPA) perform worse than the additive baseline.Line plot of the true positive rate against the false discovery proportion showing that none of the methods is better at finding non additive interactions than simply predicting no change.
