An invisible menagerie of microbes in permafrost soil acts as a global driver of Earth processes such as climate.
UA graduate student Thandiwe Mweetwa studies lions in her native Zambia, hoping to preserve their dwindling numbers.
Engineers also bring considerable expertise to the detection and prevention of infectious diseases, UA faculty members say.
The UA is the only university in the continental U.S. with one, and the state-of-the-art system has received first "light."
New facility will follow the Health Sciences Education Building, which opened in 2012 and houses health education for both the UA and Northern Arizona University.
UA scientists will be riveted by the comet Siding Spring when it passes Mars on Oct. 19. But capturing an image will be "like trying to photograph a speeding bullet while riding a roller coaster."
"Rockets to the Rescue," a hands-on challenge for 4-H National Youth Science Day, brought out the budding scientists and engineers.
What began with a regional economic development mission has since turned its attention to facilitating the testing, evaluation and demonstration of new technologies.
There's plenty of room in outer space for the OSIRIS-REx and Hayabusa2 asteroid missions, both sides say.
University's strengths underscored by opening of Arizona trade office in Mexico City and conference of North American institutions in Tucson.
Biodiversity is higher in the tropics compared with colder regions, but that's not the whole story. Functional biogeography, an emerging discipline, has brought unexpected revelations.
The College of Optical Sciences is leading an international effort to develop the technology of tomorrow.
Andrew Lincowski has designs on a career as a scientist, and his current and future colleagues say he has the right stuff.
They're creepy, crawly ... and awesome! Come inside a hands-on event as UA students explain the world of arthropods.
A large bequest to the UA Foundation from the estate of Agnese Nelms Haury, a longtime friend of the University, has pushed the Arizona NOW fundraising campaign past the billion-dollar mark.
The impact decimated slow-growing evergreens and made way for fast-growing, deciduous plants, UA researchers say, and that provides an explanation for those fall colors.
Scientists originally thought the climate pattern, which brings torrential summer rains and dry winters, began 22-25 million years ago as a result of the uplift of the Tibetan Plateau and the Himalaya Mountains. But UA researchers say that's not going back far enough.
UA scientists, including entomology expert Bruce Tabashnik, are on the leading edge of an approach to tackle global challenges in food security, emerging diseases and biodiversity loss.
A new study reveals the interactions among bacteria and viruses that prey on them thriving in oxygen minimum zones, stretches of ocean starved for oxygen that occur around the globe. The UA's newly launched Ecosystem Genomics Institute is dedicated to the researching such microbial communities in their natural environments as an important step in understanding global processes including climate.
The grant is part of a $21 million multi-institutional effort to expand knowledge of the Southern Ocean’s role in ocean health and the Earth’s climate.
