Biomedical Research
Laboratory and translational research into human biology, disease mechanisms, and therapeutic targets. Biomedical research carries the densest research-administration overlay of any field: ICMJE authorship conventions, NIH funding mechanisms, IRB and IACUC oversight, biosafety containment, and data-sharing mandates under the NIH Data Management and Sharing Policy all apply simultaneously. Content tagged here spans bench technique, compliance obligation, and publication practice.
