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...

Photoperiodic regulation of pituitary thyroid-stimulating hormone and brain deiodinase in Atlantic salmon

Seasonal timing is important for many critical life history events of vertebrates, and photoperiod is often used as a reliable seasonal cue. In mammals and birds, it has been established that a photoperiod-driven seasonal clock resides in the brain and pituitary, and is driven by increased levels of pituitary thyroid stimulating hormone (TSH) and...
