This grant is a "proof-of-principle" proposal to determine if imidacloprid, a neonicotinoid insecticide, causes obesity and insulin resistance (IR) in the insect obesity and IR model, D. melanogaster, in a manner similar, if not identical, to the effects seen with this compound when administered to mice.

The etiology of breast cancer is complex and varied. Many of the major risk factors for breast cancer, including age, reproductive history, and family history of cancer, are not modifiable. There is a great need to provide women with evidence based advice on how they can reduce their risk of developing breast cancer. Research has shown that compounds in fruits and vegetables have anti-cancer properties and most people agree that a diet rich in nutritious fruits and vegetables may help prevent breast cancer. However, the ways in which such a diet reduces risk remain unknown.
The goal of this project is to understand the many complexities of physical and mental health faced by rural low-income families within the context of their communities. Poverty is disproportionately higher and more persistent in rural areas than in urban areas and problems of unemployment, underemployment, lower wages, and poor health make it more difficult for the rural poor to escape poverty.
Well-maintained, healthy turfgrass provides many environmental and social benefits. However, multifaceted programs such as Integrated Pest Management (IPM) are needed to withstand the constant challenges by abiotic and biotic stressors year around. Integrated pest management is a comprehensive approach that brings together various cultural and chemical pest control methods to manage insects, plant diseases (mainly fungi), and weeds.
Although the medical breakthroughs in the early part of the 21st century have made significant progress in the treatment of many chronic diseases, disease prevention or even delay is of critical importance. Healthy People 2010 & 2020 and USDA dietary guidelines for Americans strongly recommend increased consumption of fruits and vegetables that are rich in antioxidants and bioactive phytochemicals to prevent or attenuate diet-related chronic diseases and to improve health.
The causes of climate change are global, but the impacts are experienced locally. Communities across the New England region and the country are facing challenges from climate change including more extreme storms, hotter and longer-lasing heat waves, more rain in winter and less in summer, as well as the slower but significant effects of sea level rise. Given the incremental development and long lives of the built environment, changes in municipal regulations take years to significantly change the buildings and infrastructure that make up our cities and towns.
After years of decline, many American cities are experiencing growth and renewal. In the first decades of the new century a host of U.S. cities saw increases in urban employment and population along with decreased rates of poverty and crime (McDonald, 2008). For the last three years data show American cities growing faster than their surrounding suburbs (Voith & Wachter, 2014).
Global climate change is altering the Earth's natural cycling of water from the ground to the air and back again, what is known as the hydrologic cycle. In New England, climate change is predicted to increase temperatures and increase the frequency and strength of rain events. The increased temperatures will result in less snow accumulation in the winter and an increased need for irrigation in the hotter summer as evapo-transpiration increases. This will alter significantly the recharge/extraction cycle. Will less water enter groundwater aquifers because of reduced snow fall?
Total wetland area in the U.S. has been in precipitous decline since the 1900's, and although recent decades have slowed the decline and advocated strongly for the services and economic benefits (not to mention ecological benefits!) these lands provide, still much more work needs to be done to preserve existing wetlands and promote restoration of impaired ones.
The safety of the food supply is a continuing issue for agriculture, with an estimated 81 million instances of food borne illnesses in the USA annually, with an estimated cost of $152 billion dollars per year to the US economy. The Center for Disease Control and prevention estimates that 46% of these illnesses were due to produce - thus food safety is very much an agricultural issue.
