Rice University scientists are forging toward tunable carbon-capture materials with a new study that shows how chemical changes affect the abilities of enhanced buckyballs to confine greenhouse gases. 

Two new studies led by UC Irvine using NASA Gravity Recovery and Climate Experiment satellite data shows that human consumption is rapidly draining some of its largest groundwater basins, yet there is little accurate data about how much water remains. 

The Colorado River Basin lost nearly 53 million acre feet of freshwater over the past decade, according to data from NASA’s GRACE mission. This is almost double the volume of the nation's largest reservoir, Nevada's Lake Mead (pictured).
August 26, 2015 | While many people take advantage of the sunshine this time of year, NCAR scientist Rita Roberts seeks out storms. Roberts is leading an experiment this summer along the Front Range to improve short-term forecasts of heavy rainfall and flash floods, particularly over complex terrain.

August 4, 2015 | For more than a decade, scientists have known that the mosquitoes transmitting dengue fever have been moving from the tropics north into the United States—as far north as New Jersey, with outbreaks in Brownsville, Texas, and heavily touristed Key West, Florida. Now NCAR scientists and their colleagues are learning more about why certain areas are prone to dengue outbreaks while others aren’t, and what factors can best predict the future impact of the disease also known as “breakbone fever."

July 8, 2015 | As a key driver of winter weather patterns across Europe, the North Atlantic Oscillation (NAO) has long sparked the interest of atmospheric researchers. Now a new study sheds light on the history of the NAO over the past 1,000 years, potentially moving scientists closer to the goal of projecting weather patterns for Europe months to years in advance.

June 17, 2015 | Water falls from the sky, runs across the earth, funnels into drainages, and fills rivers.  It seems simple. But total precipitation does not equal total streamflow. Along the way, some of the water gets sucked up by plants, absorbed by the soil, or evaporated into the air. A complex array of factors—from wind speed to geology—influences how much precipitation converts into streamflow and at what speed.

February 24, 2015 | Earth’s weather extends into higher regions of the atmosphere than the one we inhabit. But the influence of those regions has been challenging to chart until recently.
