Radical Numerics: first AI-designed phages reached a human patient — capabilities disclosed, outcomes withheld.

In a 20 October 2026 technical blog, Iyengar, Siranosian and colleagues say designs from their multimodal genome language model Omnii-1 were administered to a patient stant infection under an authorized, physician-led compassionate-use pathway. That is not a clinical-trial approval.

Hard readout
→ The company is not disclosing the patient’s clinical course or outcomes, citing privacy. It also states that these investigational therapies have not been approved for broader clinical use, and that observations from a single patient cannot establish general safety or efficacy
→ In laboratory T7 engineering, 69.9% of Omnii-1 designs with 11–15 amino acid changes were recovered after rebooting, versus 4.8% of random controls
→ Of 6,694 variants with measurable activity, 2,161 exceeded wild type, including variants with up to 28 amino acid changes; random controls that beat wild type had at most five

Worth reading when the headline is that an AI-designed therapy reached a patient, and the outcome data are not in the post.

Nature Communications: Predict the mutation effect, not just absolute kcat — DeltaCata then improved a methyltransferase’s catalytic efficiency for icaritin up to 7.0× in vitro.

Most kinetic models predict absolute kcat and Km and miss what a mutation actually changes. Yuan, at Sun Yat-sen University and the National Supercomputing Center in Shenzhen built DeltaCata, a Siamese geometric graph network that learns Δkcat and ΔKm directly from wild-type/mutant pairs measured under identical conditions.

Hard readout
→ They assembled 12,390 Δkcat and 16,010 ΔKm mutation-effect pairs from matched assays (language-model-assisted parsing plus manual review)
→ On sequence-level tests, DeltaCata reached PCC 0.568 for Δkcat and 0.364 for ΔKm, ahead of existing predictors; the lead holds at low sequence identity
→ Applied to engineer methyltransferase sGmOMT2; wet-lab catalytic efficiency (kcat/Km) for in vitro icaritin synthesis improved by up to 7.0-fold

Worth reading when enzyme models still report a single kcat and leave the mutation effect as an afterthought.

Nature Communications: Affinity or stability? LAffAb co-optimizes both — and designs didn’t collapse to one winner.

Tennenhouse, Fleishman (Weizmann) and AstraZeneca colleagues start from an antibody–antigen crystal structure and introduce combinatorial CDR mutations that he complex, instead of iterating affinity at the cost of stability.

Hard readout
→ A ~7,000-variant library with up to nine mutations; wet-lab SPR gains of up to ~30× affinity while co-optimizing stability
→ The library did not converge on a single solution. Selection favored diverse variants with a high mutational load
→ A 10-design screen against a potential drug target improved affinity by an order of magnitude with high developability; GitHub release of the RosettaScripts workflow

Worth reading when affinity maturation still feels like a serial trade-off.

Ginkgo sold its first autonomous lab to Novo Nordisk — not a paper, a purchase order.

In its Q3 2026 results (5 Nov), Ginkgo said Novo Nordisk selected it to build an autonomous lab at Novo’s new Waltham, Massachusetts R&D site. This is hardware plus software (RAC + Catalyst) goin.S. lab — not another services-only CRO story.

Hard readout
→ First announced autonomous-lab sale to a top-tier pharma company
→ CEO Jason Kelly: the U.S. government is now treating autonomous labs as national infrastructure; the Novo deal “sends a signal to all the other companies in the industry”
→ Q3 revenue $28M (−6% year over year); cash, cash equivalents and marketable securities $285M as of 30 Sept 2026

AI can accelerate a discovery without resolving its biggest mystery

Anthropic’s biology team — directing Claude at each step — reports the first 3D structure of a vault-like particle assembled from a bacteriophage protein (L05): 96 copies, ~9.5 MDa, shorter/wider than mammalian lts remains unknown after ~40 years.

Hard readout
→ Isolation cut from ~3 days to ~90 minutes; first structural model in ~34 hours of processing
→ 7 of 15 expressed candidates formed vault-like particles; cryo-EM confirmed four
→ Humans set goals and wet-lab decisions; Claude assisted search, construct design, purification, and map processing — not a solo AI discovery

Worth reading as an experiment-story on AI-in-the-loop biology — and as a reminder that speed ≠ solved biology.

Nature: AI agents that design the lab layout — then run it

Most self-driving labs only execute the workflows they were built for. Self-Building Labs (Bai, Zhao, Aspuru-Guzik & co., U Toronto / Acceleration Consortium) start from an empty room or an existing setup and fill the gapsrobot skills, and workflows.

Hard readout
→ In a real quantum-dot run: 236 OT-2 liquid-handling commands + 19 robotic transfer/seal/readout stages
→ Twin-first planning, then physical execution under human approval
→ Still a preprint — news coverage, not peer-reviewed validation of a universal unmanned lab

🧪 Library-scale screening — with a durable lab notebook the agent actually keeps.

El Agente Fármaco (Aspuru-Guzik / Matter Lab et al.; arXiv:2611.03832) isn't another one-shot docking chat. Fármaco Atlas stores molecules, metrics, and provenance in persistent SQL while tools ets — no per-compound LLM call.

Hard readout:
→ 22-task benchmark: highest mean model-judged score vs plain tools and Codex, with lower median tokens and peak context
→ TBXT: 705 → 34 selected vs expert 39 purchased; common Vina competitive (best −8.5 vs −8.4)
→ Mean QED 0.69 vs 0.52; max Tanimoto 0.30, no shared Murcko scaffolds (Caveat: agent constraints + computational only.)

🧬 One co-design model for proteins, nucleic acids, and small molecules — with a free web server.

PartiDesign (Jin, Zhang, Kang, Hou; Zhejiang University; bioRxiv 2026.11.03.763860) isn't another modality-specific generator. It jointly builds 3D structure and sequence/chemistry structure, and bond controls — including cyclic peptides and antibodies. Trained on 128 Ascend 910B GPUs.

Hard readout:
→ ProtDBench α: ordinary MPNN@1 pass rate 23.3% vs PXDesign 21.2%, BoltzGen 12.1%, RFD3 9.8%
→ Estimated GPU-day Self yield: α 16.5k passing sequences vs BoltzGen MPNN 2.7k and RFD3 1.7k
→ Peptides (Self+1 MPNN): ~17.0k linear / ~13.8k cyclic successful backbones per GPU-day vs BoltzGen ~9.1k / ~9.8k (Caveat: AF2-IG / compute-budget estimates; preprint.)

Worth reading when your binder workflow still needs a different model for each molecular class.

🧬 Alex Rives: the virtual-cell bottleneck isn’t a bigger transformer — it’s measurement.

On The Cognitive Revolution (via AI4S.fyi), Biohub’s Head of Science draws a hard line: models called “virtual cells” today don’t yet simulate a cell in a meaningful way, or experimental biology.

His split of the problem:
→ Model — transformers lack multiscale cell structure
→ Data — programmes of the cell at scale
→ Measurement — “even more fundamental”; most biology leaps came from new ways to see

What he thinks is reachable in ~5 years (hedged): from a cell’s state + an intervention, predict a distribution over next states.

Far off: a full “world model of life” at atomic resolution.

On the $1.8B Virtual Biology Initiative: first clear push = spatial maps linking molecular measurements to imaging at hundreds of billions of cells — atlases of health/disease in 1–2 years (first drafts), more comprehensive ~5 with coordinated effort.

🧬 Roche just plugged Chai into multiple discovery programs.

Chai Discovery (CAD suite for protein therapeutics) announced a collaboration: Roche will use Chai’s AI models and platform across a number of drug-discovery programs and therapeutic areas.

Hard facts from the 26-11-05 (Business Wire / Chai site)
→ Stack: Chai AI models + platform; Chai-3 cited as the latest model
→ Claim language: high target success rates and binding affinities, including challenging targets
→ Quotes on both sides (Meier, Chai CEO; Zaïtra, Roche Corp BD)
→ Latest in Chai’s 2026 big-pharma collaboration wave

What is NOT in the PR: deal size, milestones, named assets, or a peer-reviewed Chai-3 scoreboard.

📎 Describe the dataset. Agents curate it from the literature — with a source for every cell.

James Zou (Stanford / CZ Biohub) + GXL just shipped Paperclip Datasets: you name the table you want; agents search and read papers, patents, trials, and regulatory docs in parallel, able dataset where every value links back to the passage that supports it.

Hard example — human drug half-life (now on HF):
→ 19,952 terminal half-life measurements
→ 2,418 normalized drug names · 3,270 PMC papers
→ ~30× the Obach / TDC benchmark (667 compounds, one value each)
→ keeps cohort, dose, route, and paper — not one number per drug

Bonus check (GXL eval): same agent, same prompt — Paperclip matched direction + significance on 90.3% of outcomes across 20 published meta-analyses vs 72.7% with web search.

🧬 Don’t just pick the next mutant — evolve the workflow itself.

EnzymeRSI (Genoria AI; arXiv:2611.06321) is a dual-loop recursive self-improvement system for enzyme design: outer loop evolves harness assets without touching model weights; inner loop develops predictors when the k.

Hard facts:
→ Outer loop: mean ProteinGym Spearman +0.044 across 5 assays (dev set); CD19 0.314 → 0.335
→ Inner loop: ThermoMPNN PCC 0.849; TadA Spearman 0.307 in 1.13 h
→ RLuc wet-lab: 10 of 32 non-pre-specified candidates ≥2× WT activity
→ A3A: Y130Q → 90.2% 5mC conversion; preference reversed in both contexts
→ KOD-E: path selection raised catalytic efficiency to 31.1× parent on modified dATP

Honest caveat: design rank vs measured rank on RLuc was only ρ = 0.175 — pool hit, ranking miss. Preprint; multi-round closed dry→wet campaign not yet shown.

🧬 First vault particle structure from bacterial life — mapped with Claude.

Anthropic’s biology team just shared cryo-EM of prokaryotic vaults: barrel-shaped nanocapsules long known in our cells, now built from phage/bacterial MVP homologs.

Hard facts:
→ Claude Science edicted proteins
→ Homologs across 29 bacterial + 4 archaeal phyla
→ 4 complete vaults confirmed by cryo-EM (2 phage + 2 bacterial)
→ Phage L05: 96 protein chains · 54.5 × 47.5 nm · ~3.2 Å · ~25% more lumen than human vaults
→ End-to-end under 4 months; cells → grid in ~90 min; first model in 34 h
→ Humans still made the key calls (and fixed Claude’s misses — including a mirror-image map)

Bonus for protein design: add 2 wall repeats → a larger closed shell (~50% more volume than the human vault).

Function still unknown. The mystery got deeper — and engineerable.

📦 RFD4-Proteina just open-sourced its full training-structure store.

Not classic RFdiffusion — this is the Baker Lab IPD × NVIDIA GenAIR release stack. Yesterday’s Hub commit (kierandidi) moved it from a partial PDB+AFDB cut to every source used by the release flow + AE huggingface.co/datasets/nvidi…
→ 2.13 TB · 19 configs · 33,527 objects
→ AFDB monomers, PDB interfaces, PLINDER ligands, glycans/Re-Glyco (~1.57 TB alone), RNA/DNA, Ab/TCR, NCAA/PTM, TED dimers, OMol, cyclic peptides…
→ Packaging/indices: CC BY 4.0 (structures keep upstream terms)
→ Model weights already BSD-3; you don’t need this dump to run inference

Why it matters: rare for a frontier biomolecular design model to ship weights + code + the actual training shards/provenance. Reproducibility and fine-tune fuel, not just a demo.

🧬 Stop sampling binders blindly.

**ProteoCraft** (Wu, Choi et al.) reframes protein design as **proposal–verification tree search**: truncated diffusion gradients propose where to mutate; full ESMFold2 decides what’s good — coarse multi-site exploration → single-site rs from the preprint:
→ PD-L1 miniproteins (SPR): **82.9%** binding hit rate (29/35)
→ Best fitted **KD = 0.879 nM** — no affinity maturation
→ IFNAR2 VHH (BLI): binding confirmed; lead ~**153 nM**
→ In silico: strict high-confidence yield **54.3%** vs **19.0%** compute-matched Best-of-N
