Biological foundation models have hit a plateau. Scaling isn't working as expected. Foundational concepts from evolutionary biology could have predicted this: 🧵 https://t.co/Il1tsnovsD [1/9]

Biological foundation models are, at their core, evolutionary comparisons on massive scales. As with all comparative studies, evolutionary nonindependence determines their power. We chart how this...

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… 🤗🚀

Have we hit a "scaling wall" for protein language models? 🤔 Our latest ProteinGym v1.3 release suggests that for zero-shot fitness prediction, simply making pLMs bigger isn't better beyond 1-4B parameters. The winning strategy? Combining MSAs & structure in multimodal models!

Small proteins can be more complex than they look! We know proteins fluctuate between different conformations- but how much? How does it vary protein to protein? Can highly stable domains have low stability segments? @ajrferrari experimentally tested >5,000 domains to find out!

It’s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). I’m reaching out to identify clinicians/patients who have encountered pediatric IDCS, indeterminate dendritic cell histiocytosis

@cvresnick @KarlRomanowicz @kimreynolds_lab @KortemmeLab Computational: There is a huge amount of data here and we have only started scratching the surface in its analysis. We’ve already started playing around with ML models for prediction and generation. 12/n

@cvresnick @KarlRomanowicz @kimreynolds_lab @KortemmeLab Experimental: this study was only an initial pilot. We’re assembling a library 10x as large and with continuing improvements in NGS, the amount of functional data that can be collected will be incredible. 11/n
