The National Institutes of Health (NIH) announces the availability of Small Business Innovation Research Grants to support the development of chemical testing resources and approaches that better reflect the genetic diversity among human populations. The resources and approaches might include panels of human cells or cell lines, panels of cell lines generated from genetically diverse rodent strains, lower organism strains with well-characterized genetic backgrounds, or in silico approaches to enhance the ability to characterize the effects of genetic variation in toxicity testing. These grants are available only to U.S. small businesses. Letters of intent are due January 19, 2020, with applications due February 19.
