Storms on Uranus, Neptune Confined to Upper Atmosphere Applying newly developed analysis techniques to data obtained by NASA's Voyager 2 spacecraft in 1989, a team involving two UA planetary scientists discovered that weather phenomena on Uranus and Neptune are confined to the upper 680 miles of atmosphere instead of reaching deeper into the planets' interior as was previously thought.
Scheduled for launch in 2016, the OSIRIS-REx will travel to asteroid Bennu, scoop up a sample of pristine material leftover from the formation of the solar system, and return it to Earth in 2023.
UA-Led Asteroid Mission is a Go NASA has granted final approval of the OSIRIS-REx sample return mission led by the UA. The target asteroid, uniquely interesting scientifically, is one of the most potentially hazardous objects known - it has a one-in-2,000 chance of colliding with Earth in the late 22nd century. The asteroid could hold clues to the origin of the solar system.

UA Mars Camera Reveals Hundreds of Impacts Each Year Taking before and after pictures of the Martian terrain, researchers with the UA-led HiRISE camera have identified nearly 250 fresh impact craters on the Red Planet. The results provide scientists with a better yardstick to estimate how frequently craters are blasted on Mars, allowing them to assess recently formed features with greater accuracy.
A scanning electron microscope image shows the tiny, 1-millimeter-long bladders used to catch small organisms by Utricularia gibba, the humped bladderwort plant (color added). The submerged growing plant is a voracious carnivore, with its bladders leveraging vacuum pressure to suck in tiny prey at great speed. (Photo: Enrique Ibarra-Laclette and Claudia Anahí Pérez-Torres)
Carnivorous Plant Throws Out ‘Junk’ DNA UA genomics experts have helped decipher the DNA of the carnivorous bladderwort. This genome is the smallest ever sequenced from a higher plant, and scientists say that nearly all of it - 97 percent - comprises genes that code for proteins, suggesting the majority of noncoding DNA may not be crucial for complex life.
Much more suited for arid environments than rubber trees, the guayule plant is a promising candidate for more sustainable, high-yield natural rubber production. (Photo: Jack Dykinga/USDA)
UA Receives $3M Grant for Sustainable Biorubber Production The UA's Dennis Ray will lead the effort of breeding guayule, a rubber-producing plant suited for arid environments, to achieve higher yields and reduced harvest cycle time. Tech Launch Arizona, a technology commercialization center at the UA, assisted with the UA partnership with Yulex Corporation, which is providing the grant.
