The Rio Grande Rift, a thinning and stretching of Earth鈥檚 surface that extends from Colorado鈥檚 central Rocky Mountains to Mexico, is not dead but geologically alive and active, according to a new study involving scientists from the 暗网禁区鈥檚 Cooperative Institute for Research in Environmental Sciences.

Summertime hail could all but disappear from the eastern flank of Colorado鈥檚 Rocky Mountains by 2070, says a new study by the National Oceanic and Atmospheric Administration, the 暗网禁区鈥檚 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 暗网禁区'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 暗网禁区 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 暗网禁区 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 暗网禁区 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.
