Would love help identifying amazing ML researchers with strong connections to Canada who are currently outside Canada (thus potentially targets for recruitment as US situation deteriorates). DMs please. Retweet please.

These (by @mic_caprio) are really a great set of slides--they do very well to motivate credal ML and more generally the basics of imprecise probabilities-based ML. They also provide a great set of foundational references (books + papers). https://t.co/6DRyfUjWEt

Excited to unveil Boltz-2, our new model capable not only of predicting structures but also binding affinities! Boltz-2 is the first AI model to approach the performance of FEP simulations while being more than 1000x faster! All open-sourced under MIT license! A thread… 🤗🚀

There is something deeply ironic about Trump lecturing South Africa for not arresting a man for giving populist, racially charged speeches that target ethic minorities.

For over a decade at @RecursionPharma, we've been driven by a core belief: truly understanding biology, and ultimately accelerating drug discovery, starts with building the right datasets. Every week we run millions of experiments in our highly automated wet lab to generate this

Virtual Cells: Predict, Explain, Discover 1.This paper outlines a bold vision for “virtual cells”—computational models that can predict cellular responses to perturbations, explain those responses through molecular mechanisms, and discover new biology via lab-in-the-loop

Virtual cells shouldn’t just be predictive models, they should be testable theories of cell biology. They should predict cellular responses, explain them mechanistically, and discover new biology and therapies. Excited to share our perspective paper:
