Growing Hydroponic Strawberries in the Desert

Mon, 02/03/2014 - 7:52am
Chieri Kubota came to the UA from Japan with many goals, including growing strawberries hydroponically in the desert Southwest. Her focus is flavor over shelf life. Her goal is to test varieties and high-tech growing methods – then work with greenhouse growers to cultivate strawberries in the winter for local farmers markets, grocers and restaurants. Little did she know that in the 1890s Arizona was famous for its luscious off-season strawberry crop.

Pinning Down Aerosols to Shed Light on Visibility, Clouds, Climate Change

Thu, 01/30/2014 - 3:45pm
UA researcher Armin Sorooshian and his research team recently conducted two aircraft field studies to investigate haze, dust and smoke – those little-understood ubiquitous aerosol particles. In studying the properties of such particles in the atmosphere, the team is working to help scientists to better understand aerosol-cloud interactions and predict climate change.

UA Ag and Cardiology Profs Team Up to Make Implanted Devices 'Sticky'

Tue, 01/28/2014 - 11:07pm

A Living Desert Underground

Sun, 01/26/2014 - 7:15pm
UA researchers have discovered a surprisingly diverse ecosystem of microbes in a limestone cave near Tucson, Arizona, eking out a living from not much more than drip water, rock and air. The discovery not only expands our understanding of how microbes manage to colonize every niche on the planet but also could lead to applications ranging from environmental cleanup solutions to drug development.

Cave Microbes Exhibit Now Open at Kartchner Caverns

Thu, 01/23/2014 - 8:48am
A National Sciences Foundation-funded exhibit, "Journey into the World of Microbes," is now open in the Discovery Center at Kartchner Caverns, offering the public a closer look at the microscopic organisms that live in the caves. The kiosk was created to educate the public about these cave microbes, including some that are being studied by UA researchers.

UA McGuire Center Named Innovator of the Year

Wed, 01/22/2014 - 6:03am
The UA's McGuire Center for Entrepreneurship was named Innovator of the Year in academia during the Governor's Celebration of Innovation gala. All finalists for the award were from the UA, representing innovative programs in agriculture, the biological sciences and environmental science.

Managing Fires in Arizona's Sky Islands

Tue, 01/21/2014 - 8:54am
FireScape is a comprehensive effort to manage fires and ecosystems in Arizona's sky island region. The project brings together representatives from the UA, the U.S. Forest Service, The Nature Conservancy, Bureau of Land Management, National Park Service and other southeastern Arizona land managers. Firescape researchers collect extensive data for each mountain range and build interactive maps to allow for a scientifically driven approach to managing fires.

UA Computer Scientist Has 'Cloud' in View

Thu, 01/16/2014 - 8:07pm
Larry Peterson, a preeminent researcher in the areas of computer networks and distributed systems, says the current trend toward cloud computing and more reliance on network-based services is a tremendous opportunity for new breakthroughs in computing. "The cloud is changing the way computing is done and the way that networks are going to be built. We're trying to help it happen in a way that keeps the opportunities for innovation open," he said.

UA Study: Your Brain Sees Things You Don’t

Thu, 01/16/2014 - 10:06am
UA doctoral degree candidate Jay Sanguinetti has authored a new study, published online in the journal Psychological Science, that indicates that the brain processes and understands visual input that we may never consciously perceive. The finding challenges currently accepted models about how the brain processes visual information.

How Climate Change Impacts Indigenous Communities

Wed, 01/15/2014 - 4:21pm
Two UA researchers contributed to a special issue of the scientific journal Climatic Change dedicated to the impacts of climate change on indigenous communities. While tribal communities are especially vulnerable to climate change, they also have unique strengths that make them resilient, especially in combination with strategic collaborations with outside partners.
