UA Helps Build Heritage Conservation Program in Afghanistan
In an effort to help Afghanistan preserve its past, the UA is partnering with Kabul University to help build the college's cultural heritage conservation program. Three faculty members from Kabul will come to Tucson this summer to work with UA faculty and learn the latest techniques in conservation, research, artifact examination and documentation, and more.
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.
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.
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 scientists have developed a rapid DNA testing machine that would go out in the field with military and police detectives. Said the UA's Federic Zenhausern: "The advantage now of doing rapid DNA testing is we can come much closer to the crime scene."
Visitors to the new eXtension website can ask questions on topics such as climate and receive answers within 48 hours. The site is designed for a wide audience, including members of the general public who are concerned about how climate change could affect forests and recreation in their region.
In the first extensive genetic survey of microbes living in Kartchner Caverns, UA doctoral candidate Marian Ortiz has shown that some of the cave-dwelling microbes may have anti-microbial and anti-fungal properties.
UA researchers Beichuan Zhang and Chris Gniady have received a four-year National Science Foundation grant toward moving the Internet's infrastructure from "today's energy-oblivious to tomorrow's energy-efficient."
A UA study using economic models backed up by fMRI scans offers new insights on why people choose to cooperate rather than act selfishly. The study appears in the current issue of the neuroscience journal Neuron.
You slam your hand in a door, and the experience becomes etched into your brain. UA scientists have found that a protein called PKMzeta helps to store memories in our brains, and it sensitizes neurons in our spines after a painful experience.
