As we’ve pointed out, it’s important to acknowledge your NIH funding in all your publications, including research articles, press releases and other documents about NIH-supported research. Your Notice of Award includes information about such acknowledgements (also see Requirements for Acknowledging NIH-Supported Research and Attribution of NIH/NIGMS Support).
If you have more than one NIGMS or NIH award, you should only cite the grant(s) that supported the research described in the publication. The specific aims should be the determining factor. This would apply even in cases where one of the authors on the article (e.g., a technician) works on multiple projects and is paid through multiple grants, or when equipment used in the reported work was purchased on a different grant.
Acknowledging multiple awards in a publication may be taken as an indicator of scientific overlap among the cited projects. This becomes important when your next application is being considered by reviewers, NIGMS Advisory Council members and NIGMS staff. For example, when considering support of research in well-funded laboratories, our Advisory Council expects the Institute to support projects only if they are highly promising and distinct from other funded work in the laboratory.
So, please take a moment to make sure that you are citing your grants accurately in your publications and avoid pitfalls when you send in your next application.
This post does not answer the question in the title.
Avoidance of overlap is something only a bureaucrat could worry about. If *I* am involved in 2 grants, there is overlap; if my lab discusses 2 different projects at a lab meeting, there is overlap. The bottom line is that a second grant greatly improves my ability to accomplish the aims of the first grant.
NIH gives me about half of what it really costs to accomplish anything, so if you want us to do the research, please stop harassing us about meaningless “accuracy” in acknowledging grant support.
