Shelled marine creatures living in increasingly acidified oceans face a fight for survival as the impacts of climate change spread, a new study suggests.

A line of zebrafish specially generated at the University of Oregon had a key role in discovering the cause of Saul-Wilson syndrome, a rare disease seen in just 15 cases worldwide.

October 1 is New Year’s Day for water in the U.S. west. This year, Californians were bidding farewell to a dry 2018 water year (October 2017-September 2018), which saw precipitation totals fall below the annual average for much of the state.

The Arctic Ocean's blanket of sea ice has changed since 1958 from predominantly older, thicker ice to mostly younger, thinner ice, according to new research published by NASA scientist Ron Kwok of the Jet Propulsion Laboratory, Pasadena, California. With so little thick, old ice left, the rate of decrease in ice thickness has slowed. New ice grows faster but is more vulnerable to weather and wind, so ice thickness is now more variable, rather than dominated by the effect of global warming.

Prairies from California to Washington state are catching the heat not just from wildfires but also from warming temperatures. For ranchers, it all means stress on pastureland.
