Scientific Literature RAG
Grounding scientific Q&A systems in live literature search rather than a frozen corpus.
The problem
A scientific Q&A system built on a frozen training-time corpus or a static vector index of papers goes stale the moment new research is published, and in fast-moving fields (genomics, ML, epidemiology) a corpus even a year old can already be missing consequential findings.
How the workflow is built
A live search step, scoped to preprint servers and journal domains, runs alongside or in place of a static vector database when a query touches a fast-moving or recent topic, with retrieved abstracts and, where accessible, full text fed to the model as grounding context rather than relying on parametric knowledge alone.

Pitfalls to watch for
- Peer review status is often not obvious from a search result alone, and a RAG system that treats a preprint and a peer-reviewed publication with equal confidence is misrepresenting the strength of the underlying evidence.
- Scientific papers are dense and technical, and a snippet alone is rarely sufficient grounding for anything beyond surface-level questions — full-text or at least abstract-level retrieval is usually necessary for the grounding to be meaningfully accurate.
- Conflicting findings across papers on the same question are common and expected in active research areas, and a RAG system needs to surface that disagreement rather than confidently synthesizing a single answer from whichever paper it retrieved first.
