NEW Claude flags a previously unnoticed enzyme system in phage DNA

Biology asks why. AI asks again, genome-wide.

WhySquared works where artificial intelligence meets molecular biology and cancer research. We help labs and teams turn sequencing data, protein models and clinical evidence into decisions they can defend.

Why this matters now

The problem is bigger than any single lab.

Cancer cases are rising faster than our capacity to study them, and most drug candidates still fail late, after years of work. AI won't fix that alone, but it changes where the time and money go.

of drug candidates in clinical trials fail

Lack of efficacy and toxicity explain most failures, the bulk of the cost lands at the end of the process.20

10–15

years to bring one drug to patients

At a cost of around US$1 billion per successful drug. Shortening the early, computational stages is where AI is already proving useful.20

Where AI fits

From sequence to patient.

Five stages where models are already changing molecular biology and oncology, what each is used for, and the published result behind it.

    What it's used for

      Under the hood

      Four kinds of model, in plain English.

      Most of the progress on this page comes from four families of AI. Knowing which one fits a question is half the work.

      Sequence models

      Trained to fill in missing letters across billions of DNA or protein sequences. To do that well, they learn which patterns are conserved, which tells you which changes are likely to matter.

      e.g. Evo 2, AlphaGenome, ESM

      Structure prediction

      Learns how a chain of amino acids folds into a 3D shape, and how that shape fits against DNA, RNA or a drug, from structures scientists have already solved.

      e.g. AlphaFold 3

      Generative design

      Starts from noise and refines it, step by step, into a new protein, antibody or binder that meets a target. The same idea behind image generators, applied to molecules.

      e.g. Chai-2, ESM3

      Research agents

      A language model that plans, uses tools, reads the results and decides what to do next, working for hours across databases, code and, increasingly, lab equipment.

      e.g. Claude Science
      Spotlight

      Anthropic moves into the lab.

      In twelve months Anthropic went from connecting Claude to lab software to running its own wet lab. The most talked-about result so far: an enzyme system in bacteriophage DNA that Claude's agents flagged, with the caveat that nobody yet knows what it does.

      1. Claude for Life Sciences

        Connectors for Benchling, BioRender, PubMed, 10x Genomics and Synapse.org, plus a skill for single-cell RNA-seq quality control. Customers named include Sanofi, Broad Institute and Novo Nordisk.3

      2. Coefficient Bio acquisition

        Anthropic acquires the stealth AI-biotech startup in a deal reported at around US$400 million.6

      3. Claude Science and in-house drug programmes

        A research product built for reproducibility, which in a demonstration identified drug candidates for phenylketonuria. Anthropic also starts a small number of preclinical programmes for diseases drugmakers tend to neglect.4,7

      4. A wet lab run with robots

        A Bay Area lab where Claude controls equipment through the Model Hardware Standard, co-developed with HHMI. In an evaluation, Claude Mythos 5.1 produced 12 high-affinity binder candidates with a reported 50% hit rate, against a typical 10–15%.5

      5. ART: array-associated reverse transcriptases

        Agents screened public sequence data and flagged an enzyme system, mainly in phages, with a CRISPR-like repeat array. Human researchers did the lab work. Pre-print on bioRxiv.1,2

      What we do

      Models are easy to try. Hard to trust.

      WhySquared sits between the research and the lab bench: choosing the right model, wiring it into real data, and checking the output the way a diagnostics lab would.

      Variant interpretation workflows

      Pipelines that combine genome models such as AlphaGenome or Evo 2 with curated databases, so variant calls arrive with evidence attached rather than a bare score.

      → ranked variants, reasons, citations

      Structure and binder screening

      AlphaFold 3 and design models used to shortlist targets and binders before anything is ordered, with clear criteria for what goes to the bench.

      → shortlist, structures, assay plan

      Single-cell and omics analysis

      Quality control, clustering and annotation for single-cell RNA-seq and bulk data, delivered as reproducible notebooks your team can rerun.

      → QC report, figures, code

      Literature and evidence agents

      Agents that search PubMed and pre-prints, extract findings into structured tables and keep every claim traceable to a paragraph in a paper.

      → evidence tables, living reviews

      Validation and quality

      Model evaluation designed with ISO 15189 and GLP habits: defined acceptance criteria, held-out data, error analysis and documentation an auditor can follow.

      → validation plan, audit trail

      Lab data and automation

      Getting instrument output, LIMS and electronic notebooks into a shape models can use, and connecting tools like Benchling to AI assistants safely.

      → clean data layer, integrations
      How we work

      Small pilot first. Proof before scale.

      Every engagement follows the same five steps, so you can stop after any of them with something useful in hand.

      1. Scope

        Pin down the scientific question and the decision the answer has to support.

        → one-page brief
      2. Data audit

        Check what data exists, its quality, consent and licensing, and what's missing.

        → data readiness report
      3. Pilot

        Benchmark candidate models on your own data against a simple baseline.

        → comparison and recommendation
      4. Validate

        Test against acceptance criteria agreed up front, on data the model hasn't seen.

        → validation report
      5. Hand over

        Code, documentation and training so your team can run and question it.

        → working pipeline
      Responsible by design

      Powerful tools, careful hands.

      Biology AI raises real questions about safety, privacy and over-reliance. These are the rules we work to.

      Biosecurity first

      We follow the field's lead on dual-use risk: Evo 2's developers, for example, left human-infecting pathogens out of its base training data. We don't take on work aimed at making pathogens more capable.9

      Patient data stays protected

      Work involving health data follows UK GDPR, uses the minimum data needed and runs inside your own environment wherever possible.

      A qualified human signs off

      No model output feeds a clinical or experimental decision without review by someone qualified to judge it.

      Reproducible by default

      Model versions, parameters, code and data snapshots are recorded, so any result can be rerun and checked later.

      Honest limits

      What the headlines leave out.

      Good results come with fine print. We read it before we recommend anything, and we think you should see it too.

      !

      A discovery is not yet a function

      ART's role in phages is still unknown, and only the first experiment, showing the array is expressed as short RNAs, has been reported.1

      !

      Trials can miss their main goal

      NHS-Galleri did not show a significant drop in combined stage III–IV cancers. The stage IV reduction is a secondary finding awaiting peer review.16

      !

      Timelines slip

      Isomorphic Labs expected AI-designed drugs in trials by the end of 2025. Its CEO now says the first trials should come by the end of 2026.18

      !

      Humans still run the lab

      Even in Anthropic's most autonomous work, scientists chose the question, reviewed candidates and did every experiment by hand.1

      Who's behind it

      A molecular biologist who has worked the bench.

      WhySquared is led by Yılmazer Yılmaz, a molecular biologist with experience in high-throughput clinical diagnostics and hands-on lab research. The view from the bench shapes how we judge AI: a prediction is only useful if a lab can act on it and an auditor can trace it.

      Questions

      Things people ask first.

      Do we need a huge dataset to get started?

      Often not. Many of the strongest models are pre-trained on public data, so a smaller, well-curated set of your own data is enough to test whether they help. Part of the data audit is telling you honestly if what you have is sufficient.

      Can we use these models in commercial work?

      It depends on the model. Licences vary widely: AlphaFold 3's code and weights, for example, were released for academic use, and AlphaFold Server is intended for non-commercial research. We check the terms for every model before recommending it.10

      Will AI replace our wet-lab work?

      No. It changes what reaches the bench. Even in Anthropic's ART discovery, every experiment was done by human researchers. The realistic gain is testing fewer, better candidates.1

      How do you handle confidential or patient data?

      We agree the data handling up front, keep processing inside your environment where possible, and use only what the question needs. Nothing is sent to an external AI service without your explicit approval.

      What does a first project look like?

      Usually the first two or three steps of our process: a scoping brief, a data audit and a small pilot comparing models on your data. It's designed to give you a clear go or no-go before any larger commitment.
