It depends on the country but an approximation for US biomedical research is https://pubmed.ncbi.nlm.nih.gov/
although that's only journal-published information.
PubMed covers stuff from other countries as well (as does European PubMed).
Oops. Yes. What I meant to say was that US granting agencies often require published results to be catalogued through PubMed. Not that PubMed only catalogues US-based research.
