NIH's free chemistry reference — properties, safety and bioactivity for millions of compounds. Individual compound pages work well as Website sources.
Run by NIH and free to use, it's a solid reference point for a chemistry or pharmacology notebook that needs compound properties, safety data, or bioactivity numbers rather than narrative explanation. Individual compound pages import cleanly as standalone sources. It's a reference database, so pair it with a paper or review article if the notebook needs interpretation, not just data.
Import into Gemini Notebook
- 1Copy the link above (or a specific page from the site).
- 2In your notebook, click Add source → Website.
- 3Paste the link and confirm — several links can be pasted at once, one per line.
These sources mix journal PDFs, dataset docs and institutional reports — the PDF or article page imports far better than a paywalled landing page.
More science & medicine sources
- Allen Brain AtlasGene-expression and anatomy maps of mouse and human brains. Import the documentation and white papers; the atlases themselves are interactive tools.
- bioRxivPreprints in biology posted before peer review. Free PDFs of the newest life-science results — check whether a published version exists yet.
- CDC Data & StatisticsUS public-health datasets from the CDC, exportable as CSV. Pair a dataset export with the topic's fact-sheet PDFs for grounded health notebooks.
- CINAHL (Cumulative Index to Nursing and Allied Health Literature)EBSCO's index of nursing and allied-health literature. Needs institutional access; export article PDFs through your library to import them.
- ClinicalTrials.govRegistry of clinical studies worldwide. Individual trial record URLs import as Website sources with design, endpoints, and posted results.
- Cochrane LibrarySystematic reviews that weigh the medical evidence on a question. Abstracts and plain-language summaries are free; full reviews often need access.
- EmbaseElsevier's biomedical literature database, strong on drug trials, devices and conference abstracts. Subscription only — usually reached via a university library.
- Ensembl Genome BrowserAnnotated genomes for vertebrates and model organisms, with variation and comparative data. Gene summary pages make focused sources for genetics questions.
- FIFA Research ProgrammeFIFA's testing and research arm for pitches, balls and football technology. Its published standards and studies suit sports science notebooks.
- GenBankNCBI's open archive of DNA and RNA sequences. Record pages include annotations and publication links useful for genetics notebooks.
- Global Cancer Observatory (GCO / GLOBOCAN)IARC's cancer statistics hub: incidence, mortality and prevalence by country and cancer site. The fact sheets import cleanly for epidemiology research.
- Global Health Data ExchangeIHME's catalog of population health data: Global Burden of Disease estimates, surveys, and vital statistics. Good for grounding country-level health comparisons.
- Global Index Medicus (WHO)WHO search across regional medical literature databases, strong on studies from low- and middle-income countries that PubMed can miss. Many records link to open PDFs.
- International Journal of Sports Physiology and PerformanceJournal on physiology and performance in elite athletes — training load, testing, recovery. Abstracts are free; full articles are subscription-only.
- Journal of Sports SciencesPeer-reviewed research spanning biomechanics, physiology, and match analysis in sport. Subscription needed for full text; abstracts import freely.
- medRxivPreprints in medicine and public health, posted before peer review. Cite with care — flag the unreviewed status in your notebook notes when importing.
- NASA Astrophysics Data SystemThe search engine astronomers actually use — millions of astronomy and physics papers. Most records link to arXiv or publisher full text you can import.
- NatureFlagship multidisciplinary science journal. News and open-access articles import directly; paywalled papers need institutional access first.
- NIH National Library of MedicineUmbrella for PubMed, MedlinePlus, and vast biomedical collections. Start here to find authoritative health sources worth importing.
- OpenNeuroOpen brain-imaging datasets — MRI, EEG, MEG and more — in standardized BIDS format. Import the dataset descriptions and papers; raw scans stay external.
- PLOS ONELarge open-access megajournal spanning science and medicine. Every article is free full text, so PDFs import without paywall trouble.
- PubMedSearch index for biomedical and life-science literature. Grab the abstract page URL as a Website source, or pull free full text via the PMC links.
- RCSB Protein Data Bank3D structures of proteins and nucleic acids. The structure summary pages and linked primary papers are the parts worth importing for structural biology work.
- SEER (Surveillance, Epidemiology, and End Results) ProgramUS cancer statistics from the national registry — incidence, survival and trends. The cancer stat facts pages import cleanly for oncology research.
- SPORTDiscusThe main index for sports science and sports medicine literature. Subscription via EBSCO — use it to locate papers, then source the full texts elsewhere.
- UCSC Genome BrowserInteractive viewer for genome sequences and annotation tracks. Pull its help pages and track descriptions into a notebook as reference sources.
- UniProtThe reference protein knowledgebase: sequences plus expert-reviewed function annotations. Entry pages import well for molecular biology notebooks.
- WHO Global Health ObservatoryWHO's indicator database on mortality, disease burden, and health systems worldwide. Country profiles and fact sheets import cleanly as sources.
