Started my faculty role in 2019 with <300 citations and ~10 papers. Six years later: nearly 4× growth. If you feel disconnected from the broader scientific community, your path is valid. Your work matters. Your impact will find its way. Keep going.

Holy smokes... Google Drive's doc scanner is wild. > multi-page real-time scanning > auto/continuous capture > duplicate page detection > redesigned beta UI Doc scanning will never be the same... 🤯

LLMsFold: Integrating Large Language Models and Biophysical Simulations for De Novo Drug Design 1. A new computational framework called LLMsFold combines large language models with biophysical simulations to accelerate early-stage drug discovery, running on consumer hardware in minutes rather than requiring high-performance computing clusters. 2. The pipeline integrates three key components: geometry-based pocket detection using Convex Hull algorithms, molecular generation via Llama-3-70B with in-context learning, and structural validation through Boltz-2 co-folding for affinity prediction. 3. Unlike conventional approaches that require task-specific fine-tuning, LLMsFold leverages pre-trained LLM weights through carefully designed prompts with example molecules, enabling rapid target switching without retraining. 4. The system employs a reinforcement learning feedback loop where top-scoring molecules from Boltz-2 evaluation are reintroduced as prompt examples, iteratively refining candidates toward optimal binding affinity and synthetic accessibility. 5. Applied to two challenging targets—ACVR1 for fibrodysplasia ossificans progressiva and CD19 for B-cell malignancies—the method generated novel candidates with predicted nanomolar potencies that passed drug-likeness and novelty filters. 6. For the kinase target ACVR1, the top candidate showed predicted IC50 of 129 nM with high confidence metrics, while for the protein-protein interaction target CD19, the best molecule achieved predicted IC50 of 188 nM at a clinically validated epitope. 7. All final lead compounds were confirmed as novel chemical entities with no matches in PubChem, demonstrating the method's ability to explore new chemical space rather than retrieve known inhibitors. 8. The entire workflow completes in under 6 minutes on a standard MacBook Pro with M3 chip, making advanced de novo drug design accessible to academic groups and small biotech companies with limited computational resources. 💻Code: github.com/tacciolilab/LL… 📜Paper: biorxiv.org/content/10.648… #DeNovoDrugDesign #ComputationalChemistry #LargeLanguageModels #AlphaFold #Boltz2 #DrugDiscovery #Cheminformatics #MachineLearning #RareDisease #OpenScience

It's only been just over 67 hours since OpenAI dropped GPT-5.4. And people can't stop getting creative with it. 10 wild examples. Bookmark this 👇

🚨 BREAKING: Someone just open-sourced software that sees you through walls using only WIFI signals. it’s called WiFi-DensePose. It maps your exact body pose in real-time. no cameras. no sensors. just your living room router. 100% Open Source.

I packaged up the "autoresearch" project into a new self-contained minimal repo if people would like to play over the weekend. It's basically nanochat LLM training core stripped down to a single-GPU, one file version of ~630 lines of code, then: - the human iterates on the prompt (.md) - the AI agent iterates on the training code (.py) The goal is to engineer your agents to make the fastest research progress indefinitely and without any of your own involvement. In the image, every dot is a complete LLM training run that lasts exactly 5 minutes. The agent works in an autonomous loop on a git feature branch and accumulates git commits to the training script as it finds better settings (of lower validation loss by the end) of the neural network architecture, the optimizer, all the hyperparameters, etc. You can imagine comparing the research progress of different prompts, different agents, etc. github.com/karpathy/autor… Part code, part sci-fi, and a pinch of psychosis :)

Interested in molecular animation and in SF for #BPS2026? Stick around for the evening Structural Biology workshop (Rm 204/205/206) and my talk at 8:45pm (New Tools for Visualizing Dynamic Molecular Models) to learn about ProteinBlender! animation-lab.github.io/ProteinBlender/

🧪Help needed! I am currently gathering ideas for a new and updated Blender course tailored for chemists. Besides importing molecules into Blender, what topics or features would interest you the most? Any input is highly appreciated 😊
