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.

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.

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.

Dogs Experience a Runner’s High (But Ferrets Do Not)

Many runners pursue the sport for the reward that comes at the end of a race or long jog: the runner’s high. Researchers suspect that other animals adapted to run, like dogs, may experience this neurobiological response after a round of exercise, too. UA researchers decided to test this hypothesis, publishing their results in the Journal of Experimental Biology.

The microorganisms of greatest concern when it comes to leafy green vegetables are Salmonella, Listeria, enterococci, noroviruses and pathogenic forms of E. coli, says Channah Rock of the UA department of soil, water and environmental science. Units within the UA College of Agriculture and Life Sciences often coordinate efforts to assist with community and agriculture industry issues.
