  • As the world's population of older adults increases, so do conversations around successful aging — including seniors' physical, mental and social well-being.

    A variety of factors can impact aging adults' quality of life. Two big ones, according to new research from the University of Arizona, are the health and cognitive functioning of a person's spouse.

    Analyzing data from more than 8,000 married couples — with an average age in the early 60s — researchers found that the physical health and cognitive functioning of a person's spouse can significantly affect a person's own quality of life.

  • Part of the reason American shoppers are so attracted to wholesale shopping is their belief that bulk-buying not only prevents waste but can save time and money, providing more value for the dollar.

    However, results from a qualitative investigation by the University of Arizona of buying habits suggest that the opposite may be true.

    Victoria Ligon, who earned her master's degree from the UA Retailing and Consumer Sciences Program, studied food purchasing and preparation habits of U.S. consumers for her thesis, finding that those in the study tended to buy too much food and waste more of it than they realized. Ligon has begun doctoral studies in the program.

  • As he registered some time ago for the inaugural Pan American Conference on thoroughbred breeding and racing, scheduled to coincide in New York with the fabled Belmont Stakes, Doug Reed allowed himself a momentary flight of fancy.

    "Wouldn’t it be neat," he thought, "if there was the possibility of a Triple Crown winner?"

    Reed, coordinator of the Race Track Industry Program at the University of Arizona, got his wish — and so much more — at Saturday’s 147th running of the Belmont in Elmont, New York.

  • Dr. Jimmye S. Hillman, former head of the Department of Agricultural and Resource Economics in the College of Agriculture and Life Sciences, passed away from complications of a stroke on June 4th, 2015.

    George Frisvold, specialist in agricultural and resource economics, interviewed Dr. Hillman in 2004. An excerpt from this interview is republished here.

    Born and raised in rural Mississippi, Dr. Hillman first joined the faculty of the Department of Agricultural and Resource Economics at the University of Arizona in 1950, serving as Head of the department from 1961 to 1990. Dr. Hillman’s research interests centered on agricultural and trade policies.

  • His "favorite office," in his words, was the tide pools along the rocky coast of Monterey, California.

    Following the example of marine biologist Ed Ricketts, whom he admired, Raphael "Rafe" Sagarin spent much of his time as an aspiring marine ecologist observing and studying these microcosms teeming with life, pounded by waves at one moment, only to slowly evaporate under the scorching sun in the next, until they were washed over by the returning tide — all in the course of a day.

  • University of Arizona alumni entrepreneurs Ricardo Hernandez and John Jackson of Grafted Growers, LLC have been awarded a $100,000 Phase I USDA-SBIR grant. Small Business Innovation Research grants support technology innovation by providing federal research funds to help grow small, technology-based businesses.

    With the award, the two are working in collaboration with Chieri Kubota from the School of Plant Sciences and Murat Kacira from the Department of Agriculture and Biosystems Engineering at the UA, as well as with team members from the Arizona Center for Innovation and Tech Launch Arizona. The multidisciplinary team will commercialize novel crop-production strategies that got their start — and are continuing to develop — through UA research.

  • To the Earth, it was just a shudder. The sudden thrust that caused the tragedy of the Nepal earthquake on April 25 occurred about nine miles underground beneath the Himalayas, releasing built-up stress of unimaginable force along the major fault line where the Indian Plate, carrying India, is slowly diving underneath the Eurasian Plate, carrying much of Europe and Asia.

    The shudder raced around the planet, grazing the boundary where the Earth's molten core meets the so-called mantle of partially molten rock, at a depth of about 1,800 miles. Fifteen minutes later, the temblor reached Tucson, too weak to be felt by anyone but with enough force to send a stir through a highly sensitive instrument locked in a vault deep in the granite of the Santa Catalina Mountains just north of the city.

  • A large majority of Arizona residents believes the world’s temperature has been rising and that global warming will be a serious problem for the nation if nothing is done to curb it, according to a survey conducted by the University of Arizona’s Institute of the Environment and Stanford University.

    The survey also found that more than 70 percent of Arizonans support government action to reduce global warming, and a majority of state residents believes people are at least partly to blame for the planet’s warmer temperatures.

  • In the United States, nearly 15 million people and 1 in 13 children suffer from food allergy. In Arizona alone, every classroom contains at least two children with a food allergy.

    Soybeans are one of the eight foods regulated by the Food Allergen Labeling and Consumer Protection Act, or FALPA. Soybean is a major ingredient in many infant formulas, processed foods and livestock feed used for agriculture. Soybeans contain several allergenic and anti-nutritional proteins that affect soybean use as food and animal feed.

  • If you thought that a beetle with a machine gun built into its rear end was something that only exists in sci-fi movies, you should talk to Wendy Moore at the University of Arizona.

    Many beetles secrete foul-smelling or bad-tasting chemicals from their abdomens to ward off predators, but bombardier beetles take it a step further. When threatened, they combine chemicals in an explosive chemical reaction chamber in their abdomen to simultaneously synthesize, heat and propel their defensive load as a boiling hot spray, complete with "gun smoke." They can even precisely aim the nozzle at the attacker.
