Understanding the Factors that Influence Outdoor Residential Water Conservation: A Case Study in Suburban Boston

Urbanization has increased demand for water and impaired aquatic ecosystems, threatening water resources worldwide. Climate change and more frequent droughts are expected to exacerbate this situation. Residential landscaping, especially lawns, are a major factor in increasing domestic water use.

Outreach efforts have been made to promote outdoor residential water conservation and promote methods that provide ecosystem benefits. These include water harvesting using rain barrels, infiltrating storm water using rain gardens, and landscaping with native plants.

Anti-inflammatory Dietary Compounds, Wnt Pathway and the Prevention of Obesity Associated Colorectal Cancer

Mounting epidemiological and experimental evidence consistently indicates that obesity is a robust risk factor for several common cancers, and especially so for colorectal cancer. As obesity has reached an epidemic level and increases in the scope of the problem are further projected, it is critical to understand the mechanism(s) responsible for the link and thereby to develop strategies for prevent obesity-related cancer.

Biological Control of Arthropod Pests and Weeds

Classical biological control provides a sustainable, green method of controlling invasive pests permanently. The number of such pests increases yearly with each new invasion. The separate objectives in this project address a series of such invaders. The intended outcome of each objective (project) is to safely and permanently lower the density of the pest and avoid the damage it causes. Outcomes will be healthier forests and other natural ecosystems and reduced pesticide use in crops.

Changing the Health Trajectory for Older Adults Through Effective Diet and Activity

While good nutrition and moderate physical activity can promote health and delay disability in older adults, most do not follow dietary recommendations, and fruit, vegetable and whole grain consumption remains low. Several studies have indicated that older adults can increase fruit and vegetable intakes through nutrition education. Additional and innovative efforts are needed, however, to make progress toward achieving national guidelines in diverse populations of older adults.

Climate Change: Characterizing Plant Responses to Current and Future Levels of Carbon Dioxide and Ozone

Timothy and alfalfa are important forage crops that are fed to domestic animals. In future climate change, they will be exposed to elevated concentrations of carbon dioxide (CO2) and ozone (O3). We know little about how common varieties of these perennial plants respond to current levels of CO2 and O3. We do not know how cultivars of these plants would respond to future elevated levels of CO2 and O3.Plants will be exposed to current and future levels of CO2 and O3 in greenhouse exposure chambers.

Commercially-Valuable Secondary Metabolite Production Using Hyperthermophiles and Agricultural Waste as a Feedstock

In an effort to reduce dependence on petroleum, promote economic growth and diversification, and reduce human-induced climate change, the United States has developed a strategy that includes bio-based production of energy and compounds that can be used as precursors for industrial processes. It has been suggested that microorganisms with differing physiological capacities may provide an opportunity to generate commercially valuable products in a more sustainable, commercially viable manner.
