The National Nanotechnology Coordination Office (NNCO) is joining with the European Commission over the next year to host meetings for the six U.S.-EU Communities of Research (CORs) that focus on environmental, health and safety concerns related to nanomaterials. CORs were established as a means by which scientists can share protocols and identify research gaps and obstacles. Before September 30, 2015, the CORs will hold teleconferences and Webinars addressing (i) exposure through product life, with material characterization; (ii) ecotoxicity testing and predictive models, with material characterization; (iii) predictive modeling for human health, with material characterization; (iv) databases and ontologies; (v) risk assessment; and (vi) risk management and control. More details about the upcoming meetings will be posted here. See Federal Register, September 18, 2014.
