Ask one biomedical question. Follow the evidence everywhere.

EvidenceHelix connects disease biology, genetics, anatomy, drugs, trials, literature and population evidence across rights-reviewed biomedical sources. Every connection keeps its source, provenance, population context, contradictions and uncertainty, so you can trace any claim back to the original evidence. It is a research and education tool, not medical advice.

Explore every domain of biomedical research

35 integrated labs, from 3D anatomy and disease biology to clinical trials, medication safety and study-design reasoning.

  • Disease Atlas

    Plain-language disease pages connected to synonyms, phenotypes, genes, pathways, literature, trials, medications, discovery history, and related conditions.

    Full-page interactive human anatomy atlas with rotatable and zoomable reference views, named structures, organ/system layers, endocrine and blood-flow context, and trans-inclusive anatomy and care overlays.

  • Organism Dissection Lab

    Search real organism specimen media, inspect CT/mesh provenance and licensing, open source 3D viewers, and admit only commercially compatible assets into a governed EvidenceHelix dissection pipeline.

    Explore a full dental and oral/maxillofacial atlas spanning permanent and primary dentition, internal tooth anatomy, periodontium, jaws, oral cavity, nerves and vessels, development, occlusion, radiography, pathology, and source-backed evidence.

  • Mind & Brain Lab

    Explore real 3D neuroanatomy, named structures and schematic circuits, then connect a selected region to live psychiatric, neurological, sleep, cognition, medication, genetics, and disease evidence.

  • Foundational Consciousness & Soul Inquiry

    A provenance-first laboratory for competing models of consciousness, preregistered predictions, discriminating experiments, anomalies, replication, mathematical discovery, and ontology challenges without assuming a metaphysical conclusion.

  • Genetics Workbench

    Explore genes, variants, ClinVar interpretations, GWAS associations, tissue expression, pathways, phenotype matches, and disease evidence.

  • Functional Genomics

    Import expression counts and sample metadata, run quality control, define explicit contrasts and covariates, explore differential expression, inspect genes, and export reproducible analysis artifacts.

  • Plant Atlas

    Explore canonical plant identity, synonyms, morphology, functional traits, habitat, distribution, life history, phytochemistry, genetics, conservation, and source-backed human-use evidence.

  • Herbalist Lab

    Compare botanicals and herbal preparations with medications using plant identity, preparation details, phytochemistry, official drug labeling, clinical evidence, mechanistic evidence, and explicit uncertainty—without turning research into prescribing.

  • Medication & Pharmacogenomics

    Connect normalized medications to official labels, warnings, targets, pathways, pharmacogenomics, regulatory events, trials, literature, and safety signals.

  • Environment & Exposure

    Investigate chemicals, toxicology, air-quality measurements, environmental-health data, exposure pathways, population studies, and biological mechanisms.

  • Epidemiology & Population Health

    Compare prevalence, incidence, mortality, comorbidities, risk factors, geography, demographics, nutrition, laboratory patterns, and public-health trends.

  • Regulatory & Safety

    Track approvals, labels, safety communications, recalls, shortages, warnings, and post-market reports with causality caveats.

  • Similar Case Discovery

    Match combinations of phenotypes, labs, genetics, medications, exposures, disease course, and comorbidities to published or properly governed case sources.

  • Contradiction Finder

    Surface studies that appear to disagree and show differences in population, design, dose, endpoint, subtype, follow-up, and confounding.

  • Population Relevance

    Show how closely a study population matches relevant research dimensions without turning population similarity into treatment advice.

  • Discovery Timeline

    Merge disease descriptions, landmark papers, gene discoveries, clinical trials, approvals, safety events, and changing hypotheses into one evidence timeline.

  • Evidence Board

    Pin evidence from across the lab into a source-backed board that separates facts, associations, hypotheses, and unanswered questions.

  • Research Notebook

    Keep notes, saved sources, questions, hypotheses, and research sessions organized without silently rewriting the history of what you saw.

  • Clinician Question Builder

    Transform evidence and uncertainty into concise questions for a doctor, genetic counselor, pharmacist, therapist, or research team.

  • Notebook Lab

    Run browser-based Jupyter notebooks for disease exploration, genetics, epidemiology, medication research, contradiction review, and visual analysis without installing Python locally.

  • Terminal & CLI Lab

    Use an isolated Linux workspace for real shell commands while the governed EvidenceHelix CLI continues through the single scientific engine and canonical registry.

  • AI Evidence Brief

    Generate a concise research brief only from retrieved evidence, with citations, uncertainty, disagreements, and questions to discuss with clinicians.

  • Discovery Bench

    Capture observations, anomalies, candidate mechanisms, evidence needs, and uncertainty as structured research objects before synthesis.

  • Hypothesis Workbench

    Turn observations into explicit hypotheses with predictions, falsifiers, confounders, source provenance, and named quality gates.

  • Experiment Bench

    Define comparisons, outcomes, analysis plans, reproducibility requirements, and failure conditions before interpreting results.

  • Irregularity & Contradiction Engine

    Detect missing context, incompatible comparisons, and opposing claim directions as review candidates without declaring scientific truth.

  • Multi-Omics Lab

    Link genomics, transcriptomics, proteomics, metabolomics, epigenomics, and phenotype data while preserving study and sample context.

  • Environment / Exposome Lab

    Study combined environmental, chemical, geographic, behavioral, and temporal exposures without converting ecological associations into personal causation.

  • Cohort Lab

    Define and compare cohorts by eligibility, demographics, disease subtype, follow-up, missingness, subgroup structure, and external validity.

  • Causal Reasoning Lab

    Build an exposure → relationship → outcome claim, appraise it against the Bradford Hill viewpoints, map confounders and mediators, and see how far up the association-to-causation ladder the evidence actually reaches.

  • Risk & Statistics Literacy Lab

    Turn a study's 2×2 numbers into absolute risk, relative risk, odds ratio and number needed to treat — with 95% confidence intervals, 100-person icon arrays and a plain-language reading that never claims causation.

  • Study Design Lab

    See where a study sits on the evidence pyramid, what its design can and cannot conclude, which designs fit your question, and run a plain-language risk-of-bias checklist.

  • Cancer Discovery Lab

    Search real cancer research publications and registered clinical trials.
