Immuno-Oncology Translation Network (IOTN): Cancer Immunoprevention Research Projects (U01)
The purpose of this specific FOA is to establish Cancer Immunoprevention Research Projects that will function as components of a Cancer Immunotherapy Consortium (CIC), which will also include Cancer Immunotherapy Research Projects. The CIC will form an integrated network of multi-disciplinary, collaborative teams with the overarching goals of accelerating translational research of innate and adaptive immune mechanisms that contribute to tumor initiation and progression, and evaluating new or improved immunopreventive and immunotherapeutic strategies (including combinations with standard or other therapies). Studies should be largely pre-clinical involving clinically-relevant models and endpoints, and have the potential for rapid translation into early-phase clinical applications. RFA-CA-17-046
Tobacco Regulatory Science (R01)
The purpose of this Funding Opportunity Announcement (FOA) is to invite R01 applications to support biomedical and behavioral research that will provide scientific data to inform regulation of tobacco products to protect public health. Research Projects must address the research priorities related to the regulatory authority of the Food and Drug Administration (FDA) Center for Tobacco Products (CTP). The awards under this FOA will be administered by NIH using funds that have been made available through FDA CTP and the Family Smoking Prevention and Tobacco Control Act (P.L. 111-31). Research results from this FOA are expected to generate findings and data that are directly relevant in informing the FDA's regulation of the manufacture, distribution, and marketing of tobacco products to protect public health.

Worker Training Program (WTP) Ebola Biosafety and Infectious Disease Response Training (UH4)
The NIEHS WTP Ebola Biosafety Training and Infectious Disease Response Initiative – developed in partnership with CDC, HHS, ASPR, OSHA, and NIOSH – invites applications for cooperative agreements to support the development and implementation of occupational safety and health and infection control training programs for workers who may be at risk during infectious disease outbreaks. The major objective of this funding opportunity is to assist in the training and education of workers within the US in understanding how infectious diseases with varying transmissibility, incubation periods and clinical outcome are spread in an occupational environment and what measures can be taken to shield workers from potential exposure. RFA-ES-15-018
Children's Health Exposure Analysis Resource (CHEAR)
NIEHS is establishing an infrastructure, the Children's Health Exposure Analysis Resource (CHEAR), to provide the extramural research community access to laboratory and statistical analyses to add or expand the inclusion of environmental exposures in their research. The National Institute of Environmental Health Sciences (NIEHS) intends to promote the characterization of the exposome ( as originally defined by Christopher Wild in his 2005 Cancer Epidemiology, Biomarkers, and Prevention paper as the totality of environmental exposures from conception through development, including chemical, physical and biological stressors as well as lifestyle and social environments) in studies of children’s health through the establishment of an infrastructure to enable the measurement and integration of environmental exposures. NIEHS is publishing three distinct but integrated Funding Opportunity Announcements (FOAs) that solicit a coordinated network of laboratories and statistical and data science resources to provide access to comprehensive exposure analysis that can be performed using biological samples collected in studies of children’s health. This resource will be known as the Children's Health Exposure Analysis Resource (CHEAR). ES-15-009, ES-15-010, ES-15-011
Centers of Excellence on Environmental Health Disparities Research (P50)
This Funding Opportunity Announcement (FOA) encourages grant applications to support Centers of Excellence on Environmental Health Disparities Research to stimulate basic and applied research on environmental health disparities. The proposed research is expected to develop innovative approaches to understand environmentally-driven health disparities and improve access to healthy environments for vulnerable populations and communities. The proposed Centers are expected to support research efforts, mentoring, research translation and information dissemination. RFA-ES-14-010
Children's Environmental Health and Disease Prevention Research Centers (P50)
NIEHS and EPA will continue to support and facilitate integrated fundamental, clinical, laboratory, and public health science to: (1) identify the harmful influences of environmental exposures and changing environments as well as the protective and nurturing impact of healthy environments on normal physiological function of organs and systems of the fetus/child during gestation/childhood/adolescence; (2) determine the mechanisms of vulnerability to environmental stressors of the fetus and young child at all stages of early development; and (3) consider children’s health from a holistic perspective where the impact of complex environmental exposures may be exacerbated by non-chemical stressors encountered in community settings.
Chemical stressors may be considered as single chemicals, or as mixtures and aggregates as may be found in consumer products used by children and environments and microenvironments frequented by children. Non-chemical stressors include mediating and modifying factors such as economic deprivation, discrimination, poverty, lack of health care, fear of crime, diet and nutrition, physical activity, psychosocial factors, and the design of the built environment (e.g., settings: home, school, play areas) from birth through young adulthood. Non-chemical stressors, social and cultural factors, and settings cannot be considered alone, but they may be included as modifier variables to the primary environmental stressor(s). RFA-ES-14-002

Other Implementation Activities
A Community Conversation on Toxics, Climate Change & Health On May 21, Dr. Linda Birnbaum, participated in a Community Forum in Brooklyn, NY. The industrial waterfront is one of the city’s last working waterfronts. It is known for its port facilities, maritime commerce, and vibrant industrial sectors. The waterfront is home to several manufacturers ranging from apparel to woodwork. Due to the industrial and manufacturing nature of the waterfront the community has faced a number of disproportionate environment and health burdens such as a bus depot, numerous truck routes, including the overtaxed Gowanus Expressway, two New York Power Authority electrical turbine engines with 100 tons of yearly emissions, three antiquated power plants, a sludge transfer facility and dozens of brownfield sites. Birnbaum joins community leaders at forum in Brooklyn.
One Bioregion/One Health This new framework provides an approach to transboundary regional planning that considers relationships between people and nature in the quest for healthier living spaces. The One Health concept acknowledges that human health is interconnected and dependent on the health of animals and the environment. A bioregion is a territory that is socially and culturally defined by its people rather than borders on a map. Bioregions are shaped by global trends, including climate change, food and water issues, economic crisis, large-scale natural disasters, and widespread increases in preventable diseases. The framework, funded in part by NIEHS and developed by researchers at the University of California-San Diego Superfund Research Center, merges regional planning and ecosystem management as a way to improve public and environmental health. Bioregional planning to improve public and environmental health.
