Robert Collier, professor of animal and comparative biomedical sciences at the University of Arizona College of Agriculture and Life Sciences, and graduate student Xavier Ortiz are attempting to answer the question of cost-effective cooling for heat-stressed dairy cows.

As the climate gradually warms, issues related to heat stress in cattle increase demand for new and more efficient approaches to cooling as the hot summer months cost the U.S. dairy industry close to $900 million each year.

Most dog owners will tell you their furry friends make them feel good emotionally. But the health benefits of owning a dog may not end there.

Researchers at the University of Arizona are recruiting participants for a study exploring whether dogs can improve human health by having a probiotic effect on the body. The research will focus specifically on dogs' effect on the health of older adults.

"We've co-evolved with dogs over the millennia, but nobody really understands what it is about this dog-human relationship that makes us feel good about being around dogs," said Kim Kelly, an anthropology doctoral student and one of the primary investigators on the study.

California wildlife officials this year have been urging the public to get rid of their bird baths and feeders.

The reason? Rising concerns that non-native pigeons are spreading an infectious disease (avian trichomoniasis) believed to be killing band-tailed pigeons, the state's only native pigeon species.

Elsewhere, bird flu is a rising concern. The U.S. government this month confirmed a case of bird flu — the H5N2 strain — in Arkansas, noting that the disease is threatening the poultry industry in the Southeast. The H7N9 strain, which may cause illness in humans, was found in Canada earlier this year. Additionally, the U.S. Department of Agriculture confirmed H5N1 in wild duck in Washington state in January — the nation's first confirmed case in a bird.

Kansas State University, University of Arizona and USDA-ARS collaborate to train scientists and students in field phenomics.

High-throughput phenotyping, a new area of agricultural research, is key to accelerating progress in crop improvement. To ensure continuing advances, there is a critical need to train graduate students and scientists in this emerging technology. 

Fifty-five graduate students, researchers and industry representatives from around the world are participating in a second workshop on field-based phenotyping at the University of Arizona Maricopa Agricultural Center (MAC) in Maricopa, Arizona March 16-19, 2015.

The M.S. program in the Department of Agricultural and Resource Economics in the UA College of Agriculture and Life Sciences was recently ranked 11th in a ranking of 137 master's programs in economics.  If compared only to public universities, the program ranks 7th.  The program was cited in the 2015 Master of Business Rankings issued by The Financial Engineer: https://www.thefinancialengineer.net/economics-rankings/

The ranking is particularly interesting because no master's program in agricultural and resource economics ranked higher than Arizona's.

Officials for the University of Arizona Veterinary Medical and Surgical Program announced today they will be teaming up with The Hermitage No-Kill Cat Shelter to offer fourth-year veterinary students clinical training in the area of feline medicine.

By collaborating with the Hermitage, veterinary students will experience the inner workings of a shelter environment and deal with a range of feline related issues including Feline Immunodeficiency Virus (FIV),  Feline Leukemia Virus (FeLV), routine spay/neuter and dental procedures. In addition to their clinical work, students will also learn about shelter operations, compassion fatigue and the No-Kill movement.

The deaths of three people and illness in 200 others because of an E.coli outbreak in California spinach in 2006 shook the fresh produce industry.

Since then, farmers in Arizona and California, the two states producing almost all of the nation's leafy greens, have worked to develop new approaches to food safety.

Evidence of the work is visible in a romaine lettuce field in Yuma, where 20 workers emerge from the field and take turns washing their hands.

With three campuses, 160 telemedicine sites and Cooperative Extension offices in every Arizona county, the UA has a wide-ranging impact beyond its main campus in Tucson.

A new tool is now available that illustrates the UA's significant presence across the state.

The UA Impact Map, viewable at arizona.edu/impact-map, shows the UA’s statewide impact in a variety of areas. For example, it includes data on the number of UA students, alumni and employees in Arizona, as well as the number of degrees awarded throughout the state.

As the state's only land-grant institution, the University of Arizona has led outreach efforts through its Cooperative Extension offices across Arizona. Now the UA is assisting efforts to build a similar network south of the border.

The UA-led project, announced at Thursday's meeting of the Arizona Board of Regents, is called the Red de Extensión e Innovación Nacional Universitaria, also known as project REINU. The name translates to the National University Extension and Innovation Network.

Gay, lesbian, bisexual and transgender adolescents who come out at school have higher self-esteem and lower levels of depression as young adults, compared to LGBT youth who don't disclose their sexual orientation or gender identity at school, according to a new study led by University of Arizona researcher Stephen Russell.

Published in the American Journal of Orthopsychiatry, it is the first-known study to document the benefits of being out during adolescence, despite the fact that teens may experience bullying when they openly identify as LGBT.

Even though the Mediterranean diet is traditionally seated in the sea region around the southern region of Europe, the northernmost tip of Africa and the Middle East, it can be adapted to arid lands — and research indicates an environmental benefit associated with adopting the diet.

During the fifth annual Research Frontiers in Nutritional Sciences Conference, recently held at the University of Arizona, researchers and practitioners shared current research about the Mediterranean diet and ways they are advocating for the preservation and broad-based incorporation of the eating pattern.

Cochise County rancher John Ladd explains how people cut the fence to cross where his ranch abuts the border.

The big border barriers used to curb the flow of illegal immigrants and drugs from Mexico are having detrimental effects on wildlife, environmentalists say.

Advocates for a tighter border say security for Americans should trump consideration for animals.

The issue manifests itself in Cochise County, where the San Pedro River, which originates in Sonora, Mexico, and flows into Arizona, is a route for wildlife. It's one of the few spots for animals to cross from one country to the next, and the big fence on either side of it is a problem, a Sierra Club official said.

University of Arizona researchers and a group of partners have developed a tool that will help utility companies better understand the long-term impact of renewable energy on the power grid and provide insight on how to integrate these resources in the future in the most cost-efficient and reliable way for consumers.

The tool — a web portal — gathers, analyzes and displays real-time data from eight Southwestern utility companies, painting a broad picture of energy sources and use across the region. The information will help companies determine what actions to take for backup power planning over the next several years as the percentage of renewable energy usage grows.
