Geoscience is an all-encompassing term used to refer to the earth sciences. Geoscientists strive to understand earth processes and study the origin and evolution of our planet; the chemical and physical properties of minerals, rocks, and fluids; the structure of our mobile crust; the history of life; and the human adaptation to earthquakes, volcanoes, landslides, and floods.

Terry Spell and Dawn Reynoso of the University of Nevada joined the group, which opened a new species of narrow-nosed primates that lived about 22 million years ago. They were called Alophia - on the found remains of the teeth of these monkeys there were no special crests distinguishing them from the fossils of the teeth belonging to the younger subspecies.

Lawrence Livermore National Laboratory (LLNL) scientists in collaboration with University of Nevada Las Vegas (UNLV) have discovered a previously unknown pressure induced phase transition for TATB that can help predict detonation performance and safety of the explosive. The research appears in the May 13 online edition of the Applied Physics Letters and it is highlighted as a cover and featured article.
