Biomedical research advocates in the United States are calling for policy changes to ease boom-and-bust research-support cycles at the US National Institutes of Health (NIH). In a joint report, United for Medical Research, a research advocacy group, and the Information Technology & Innovation Foundation, a think tank in Washington DC, outline strategies to make the NIH budget more certain from year to year. These include apportioning federal funds for several years at a time and stipulating that any unspent funds can be rolled over to the next fiscal year.
