Summertime hail could all but disappear from the eastern flank of ÃÛÌÇÖ±²¥â€™s Rocky Mountains by 2070, says a new study by the National Oceanic and Atmospheric Administration, the University of ÃÛÌÇÖ±²¥ Boulder’s Cooperative Institute for Research in Environmental Sciences and the National Center for Atmospheric Research.

How did insects get their hearing? A new study of 50-million-year-old cricket and katydid fossils sporting some of the best preserved fossil insect ears described to date are helping to trace the evolution of the insect ear. According to paleontologist Dena Smith of the University of ÃÛÌÇÖ±²¥ Boulder's Museum of Natural History and University of Illinois Professor Roy Plotnick, who collaborated on the new study at the National Evolutionary Synthesis Center, or NESCent, in Durham, N.C., insects hear with help from some very unusual ears.

A University of ÃÛÌÇÖ±²¥ Boulder team is partnering with the United States Agency for International Development to assess snow and glacier contributions to water resources originating in the high mountains of Asia that straddle 10 countries.

Two University of ÃÛÌÇÖ±²¥ Boulder researchers who have adapted a three-dimensional, general circulation model of Earth's climate to a time some 2.8 billion years ago when the sun was significantly fainter than present think the planet may have been more prone to catastrophic glaciation than previously believed.

A team of researchers led by the University of ÃÛÌÇÖ±²¥ Boulder has discovered the first prehistoric bronze artifact made from a cast ever found in Alaska, a small, buckle-like object found in an ancient Eskimo dwelling and which likely originated in East Asia.

A new study of sediments laid down shortly after an asteroid plowed into the Gulf of Mexico 65.5 million years ago, an event that is linked to widespread global extinctions including the demise of big dinosaurs, suggests that lowly worms may have been the first fauna to show themselves following the global catastrophe.

The blanket of sea ice that floats on the Arctic Ocean appears to have reached its lowest extent for 2011, the second lowest recorded since satellites began measuring it in 1979, according to the University of ÃÛÌÇÖ±²¥ Boulder's National Snow and Ice Data Center.

American pikas, the chirpy, potato-sized denizens of rocky debris in mountain ranges and high plateaus in western North America, are holding their own in the Southern Rocky Mountains, says a new University of ÃÛÌÇÖ±²¥ Boulder study.

A new University of ÃÛÌÇÖ±²¥ Boulder study indicates a major climate oscillation in the Southern Hemisphere that is expected to intensify in the coming decades will likely cause increased wildfire activity in the southern half of South America.

An international team of researchers has combined data from multiple sources to provide the clearest account yet of how much glacial ice surges into the sea following the collapse of Antarctic ice shelves.
