What Sureno Explained is

Plain-language explainers on the things people are searching for: news, science, health, money, technology, everyday life. Each one tries to answer what happened, why it matters, what it means for you and what is still unknown, with every source linked.

How an explainer is made

1. Choosing a topic. Sureno watches public signals of what people want to know (Google Trends, Wikipedia's most-read pages, stories covered by several publishers, official announcements) and questions people search for all year. Tragedies, crime, gossip, gambling and election claims are excluded automatically.
2. Research. It gathers sources: official and public-domain data, open data, and reporting from named publishers, read for facts only and honouring each site's robots.txt.
3. Writing, with AI. An AI model writes a first draft from those numbered sources only, in plain language, citing a source for every specific claim.
4. Automatic checks. Before anything is published, software checks the draft: length and structure, that every citation points to a real source, that nothing is copied from a source, that the headline is not clickbait, and that it does not duplicate an existing page. Drafts that fail are not published.
5. New research. Research summaries start from the newest papers in Europe PMC (journals indexed by PubMed, and preprint servers such as medRxiv and bioRxiv) and arXiv. Solid studies in people come first; each summary says what kind of study it was, what it found, what it does not show, and whether other scientists have checked it yet ("peer review"). One study rarely settles a question, and the pages say so. Thank you to arXiv for use of its open access interoperability.
6. Background explainers. When little has been reported about a subject yet, Sureno may explain the subject itself (who or what it is) from a reference such as Wikipedia and well-established general knowledge, without specific facts that are not in the source. These pages say so at the top, do not cover the latest news, and are never used for health, money or legal topics.
7. Pictures. Each article gets a real photo whose licence allows it (from Wikimedia Commons, Openverse or NASA), credited under the picture. When none fits, it gets an illustration made with AI, labelled as such; these are calm, symbolic pictures, never made-up photos of real people or events.
8. Care levels. An article is published once it passes the checks. Health, money, legal and safety topics are written as careful summaries of official sources.
9. Looking after the library. Pages are refreshed when the facts change, hidden from search when they are no longer useful, and retired when they are out of date.

What we never do

• Give medical, legal or financial advice. Health and money pages explain; they always point you to a professional.
• Invent quotes, studies, numbers or sources.
• Copy other publishers' writing, or use photographs without a licence that allows it.
• Write about private individuals, or chase tragedies for clicks.
• Pretend a person wrote something they did not.
