Scouting Frontiers in AI for Biology: Dynamics, Diffusion, and Design, with Amelie Schreiber

**Amelie Schreiber** (0:00)
I saw people designing mechanical degraders that pulled apart like the needle complex of bacteria so that the bacteria couldn't infect the cell. And they were actually able to like pull apart the needle complex of the proteins that they designed and prevent infection. If you can scale that process and have an agent drive a big complicated workflow and solve a task, and you can just like churn out molecules, that changes things a lot. If you're interested in biochem and you're interested in AI, I would highly suggest getting into it as soon as possible because it's very fast moving, very fast paced, but also just really beautiful. And the things that we can accomplish with this are going to be great.

Hello, and welcome back to The Cognitive Revolution. Before getting started today, I want to take a moment to invite all of you to submit questions for an Ask Me Anything episode that we'll be producing in the next couple of weeks. From practical application to galaxy brain philosophy to parenting and career choices in the age of AI, I may not have all the answers, but it's all fair game to ask. And while you're there, we'd appreciate it if you'd complete a short survey so that we can learn more about the audience and how we can serve you better. All of the questions are optional, it's fine if you want to be anonymous, and we do have a few thank you gifts planned as a token of our appreciation. That said, today I'm excited to welcome Amelie Schreiber, Computational Biochemist and AI Researcher back to the show for our second deep dive into frontier developments in AI for biology. Our first conversation just over six months ago now offered a fascinating glimpse into how AI is transforming humanity's ongoing quest to understand life at the molecular level, and to harness that knowledge for everything from medicine to industrial process. And it prompted perhaps the single biggest update to my personal worldview of any episode we'd done up to that point. Since then, the pace of progress in AI for biology has, if anything, accelerated. We now have AlphaFold 3, which extends the structure prediction paradigm to include RNA, DNA, small molecules, metallic ions, and critically ensembles of all of these. ESM3, a new multimodal model that combines sequence, structure, and function, and an ever-growing library of specialist models as well. Of course, no single podcast could hope to be comprehensive in such a fast-moving and expanding space, but Amelie does an amazing job of keeping up with the literature, and in this conversation serves as an incredible guide to recent advances and current challenges. She helps me understand why modeling dynamics, not just static structures, is the new frontier, how molecular dynamic simulation models like MDGen are dramatically accelerating what traditional computational methods can achieve, and the recent introduction of diffusion models that specialize in shorter sequences of amino acids called peptides, which are often less structured than larger proteins and thus generally much harder to model. Now a big part of what makes Amelie's perspective so valuable is her unique understanding of how all these tools relate to one another and can ultimately be used together. As researchers explore ways to chain these specialized models together to orchestrate the entire protein design workflow, what emerges is a new paradigm of increasingly AI-assisted and even AI-driven protein engineering and drug discovery that promises to be dramatically more efficient, more creative, and more tuned to the nuances of biology than anything we've seen before. Big picture, these workflows could make even the most complex protein engineering tasks, like designing enzymes that catalyze entirely new reactions, which would have seemed like pure science fiction not long ago.
Not just achievable, but perhaps even accessible and affordable over the next few years. As always, if you're finding value in the show, please share it with a friend, post about it on social media, or leave us a review on Apple or Spotify. I sincerely believe that many more people should be paying attention to the developments happening right now in AI for biology. I plan to do a lot more episodes in this area, and I appreciate you helping to spread the word. Of course, we always welcome your feedback and suggestions too. You can contact us via our website, cognitiverevolution.ai, and there you'll find a link to the AMA form and the survey right at the top. Of course, you can feel free to DM me on your favorite social network as well. For now, I hope you enjoy this update on recent advances in AI for biology with computational biochemist and researcher, Amelie Schreiber.
