Dysbiosis, immunomodulation, and health effects of agricultural pesticides in wild prairie grouse

Agrochemical pollution poses a severe threat to biodiversity.  Agrochemicals can detrimentally affect wildlife growth, development, survival, reproduction, and immune responses, which facilitates emergence and spread of infectious diseases that may cause unusually high mortality.  Animal microbiota plays a fundamental role in host’s food detoxification and defense against pathogens, regulates...

Geologic Energy Storage

The United States (U.S.) domestic energy supply increasingly relies on natural gas and renewable sources; however, their efficient use is limited by supply and demand constraints. For example, a) in summer, natural gas production may outpace home heating fuel demand and b) in daytime, wind and solar electricity production may outpace industrial power requirements. Storing rather than dumping...
