A study in mice shows certain types of pain can be prevented or reversed without apparent side effects by silencing a gene involved in pain signaling. "It's a beautiful piece of work," said Rajesh Khanna, a neuroscientist who studies pain mechanisms and potential treatments at the University of Arizona College of Pharmacy. Despite successes of gene therapy against rare and life-threatening disorders, few teams have explored genetic approaches to treating pain, he said. "I think this study is going to be our benchmark."

Arizona's Native American population has been hit disproportionately hard by the COVID-19 pandemic. Native Americans make up about 5% of Arizona's population but at least 8% of the state’s deaths from the virus.

Agnes Attakai, a member of the Navajo Nation and director of Health Disparities Outreach and Prevention Education at the University of Arizona's Mel and Enid Zuckerman College of Public Health, is interviewed.

Within shoeboxes, beef jerky bags and TV bubble wrap, lie tiny white packets stamped with a very clear "DO NOT EAT" warning.

Tucson nonprofit Integrative Touch for Kids is using telehealth to reach out and help kids and caregivers – including physicians and other health-care providers – to care for themselves during the pandemic. "By helping to care for the caregivers and heal the healers, the program has an incredible ripple effect when you consider all of the patients, colleagues and staff that the providers impact," said Dr. Elizabeth Kyle Meehan, program director of the Family Medicine Residency at the University of Arizona College of Medicine – Tucson South Campus.

Dr. Shad Marvasti, director of public health, prevention and health promotion at the University of Arizona College of Medicine – Phoenix, discusses the efficacy of current COVID-19 vaccines.
