A new study at The University of Texas at Arlington will look at how situational judgement tests (SJTs) can enhance soldier ingenuity in high-stakes environments.

CHICAGO, IL — Since the start of the 21st century, more than 800,000 people in the US have died from firearm-related injuries, and over two million have been injured. These harms stem from homicide, suicide, and unintentional shootings, reverberating through communities and resulting in psychological, social, and economic consequences that go far beyond physical injury.

Amid these persistent challenges, JAMA and JAMA Network convened a JAMA Summit in March 2025, bringing together 60 thought leaders from medicine, public health, law, industry, and community violence intervention, with a singular focus: how to substantially reduce firearm harms. Today, JAMA publishes the JAMA Summit Report on Reducing Firearm Violence and Harms, a blueprint for action featuring experts from across sectors committed to advancing evidence-based solutions to reduce firearm-related injury and death.

A new report proposes a range of initiatives to substantially reduce the harm caused by firearm violence in the United States over the next 15 years. The report, to be published Nov. 3 in the journal JAMA, proposes a range of initiatives. These include using artificial intelligence (AI) and other technologies to detect concealed weapons, and expanding programs that address poverty, social distrust and other factors behind violence in American communities. Since 2000, more than 800,000 Americans have been killed and more than 2 million injured by firearms. The report summarizes discussions of 60 experts in public health, criminology, sociology, social work, public policy and other fields. “We really tried to step back and think about what innovations are needed to address the firearm problem in a new way — realizing we live in a country with a Second Amendment and somewhere around 400 million firearms in private hands,” said Dr. Frederick P. Rivara, professor of pediatrics at the University of Washington School of Medicine. He chaired the summit. 

Skipping breakfast or practicing intermittent fasting is unlikely to cloud most adults’ thinking in the short term, according to research published by the American Psychological Association.

HIV can throw the body clock off balance, leaving many people living with the virus in a constant state of “jet lag,” according to a new study in The Lancet HIV involving Wits University researchers.

The study—co-authored by Professors Xavier Gómez-Olivé and Karine Scheuermaier—found that people living with HIV (PLWHIV) experience higher rates of fragmented, non-restorative sleep even when their virus is well controlled. These disruptions are linked to increased risks of heart disease, depression, and cognitive decline. The study identifies biological and social contributors—from immune activation and treatment side effects to stress, stigma, and unsafe environments—and proposes a four-step clinical pathway that any healthcare provider can apply.
