UA scientists Thomas Galarneau and Xubin Zeng say this year's hurricane activity isn't too unusual. However, two Category 4 storms hitting the U.S. does qualify as exceptional.
The fall series, conducted across four Tucson-area locations, brings the community together with UA faculty and graduate students.
UA professor Alfred McEwen recounts some of the highlights of NASA's Cassini-Huygens mission, in which UA researchers played significant roles. The spacecraft's final plunge into the upper atmosphere of Saturn on Friday will mark the end of the nearly 20-year mission.
Utilizing computational resources, a UA course developed a map to predict the abundance of mosquitoes carrying diseases such as Zika virus and Dengue fever across the U.S.
With a solar-powered purification system and lab on wheels, researchers extend infrastructure to an Arizona community whose groundwater is high in salinity and contaminated with metals.
The endowment from Edward P. Bass will enable Biosphere 2 to address some of the century’s most critical questions in food, water and energy security as the world's population nears 8 billion. "The University of Arizona is ideally suited to make the most of Biosphere 2's resources," Bass says.
The aftermaths of Harvey and Irma revealed vastly different approaches to city planning for long-term flood control, according to UA professor Arthur C. Nelson.
As the OSIRIS-REx spacecraft performs a maneuver to embark on its trajectory to asteroid Bennu, scientists and engineers from all of the mission's teams convene at the UA.
Asteroid 288P, first discovered more than a decade ago by the UA's Spacewatch program, is one of the most unusual known objects of the main asteroid belt between Mars and Jupiter. It's the first known binary asteroid also classified as a comet.
Researcher Robert Norwood, whose solar-energy work spans two technology development programs, has been selected for two projects by the Department of Energy.
Researchers at the UA-led CLIMAS program will assess how Southwestern adaptations to extreme climate are functioning — and how that might change in the future.
Residents of Maricopa County are helping UA researchers in a mosquito study designed to improve methods of controlling future dengue fever and Zika outbreaks.
Research led by UA neuroscientists sheds light on the evolution of some of the earliest brain structures and stirs up questions about centers that support learning and memory.
During the recent flyby, the spacecraft's cameras and spectrometers produced new views and never-before-collected optical data of Earth from as close as 69,000 miles.
Tabby's Star has attracted attention from astronomers and invited speculation about whether it could be surrounded by a vast structure built by an alien civilization.
Humans migrated out of Africa as the climate shifted from wet to very dry about 60,000 years ago, according to research led by UA geoscientist Jessica Tierney.
With about 35 percent of homes in the Navajo Nation not connected to central power or drinking water, a new UA research traineeship is aimed at addressing such challenges.
Pest resistance to genetically engineered Bt crops is evolving faster now than before, UA researchers show in the most comprehensive study of adaptation to date.
For the first time, scientists including the UA's David Sand have directly detected gravitational waves — ripples in space and time — in addition to light from the spectacular collision of two neutron stars. The implications are profound for our understanding of the cosmos.
