Great Salt Lake on path to hyper-salinity, mirroring Iranian lake, new research shows

Starved for freshwater, the Great Salt Lake is getting saltier. The lake is losing sources of freshwater input to agriculture, urban growth and drought, and the drawdown is causing salt concentrations to spike beyond even the tolerance of brine shrimp and brine flies, according to Wayne Wurtsbaugh from Watershed Sciences in the Quinney College of Natural Resources.

Testing: Space-bound US-European water mission passes finals

It's bombarded with louder noise than a stadium rock concert. It's frozen, baked, and irradiated in a vacuum chamber that simulates the extremes of space. The Surface Water and Ocean Topography mission (SWOT), a...

Video footage provides first detailed observation of orcas hunting white sharks in South Africa

One predation event was filmed...
