Australia's new ban on social media for under-16s should be judged on much more than whether adolescents stay offline, researchers say. Experts from Flinders University say success of the policy should be measured by its impact on young people's mental health, school performance, digital literacy, and how they spend their time outside of social media. They also warn that restricting access may have limited impact unless social media platforms themselves are required to build safer environments to prevent young users from accessing harmful content.

Many seriously injured patients in Global South countries are failing to reach medical care within the lifesaving "golden hour" and ambulances are often associated with these delays.

The community-based opioid treatment program Honor's HEROES at UTHealth Houston may significantly improve treatment retention and quality of life for people with opioid-use disorder, even among those facing major barriers such as homelessness, lack of insurance, and prior overdose, according to a new study published in the Journal of Addiction Medicine.

Scientists are making rapid progress toward a long-awaited goal that could help to reshape cancer care: mRNA cancer vaccines with the potential to significantly boost the immune system's ability to fight and eliminate tumors.

Fatty liver disease is when too much fat builds up in the liver. The liver is the body's filter. It helps clean the blood, store energy and process nutrients. If too much fat stays in the liver, it can harm the organ and lead to serious health problems.

New research indicates that the long-term neurological impact of childhood trauma is not permanently etched onto the brain. An analysis of brain communication patterns in a group of individuals who have experienced childhood adversity shows that lifetime physical activity can reshape neural connectivity, thereby strengthening the brain's internal communication and optimizing its response to stress. The findings from the study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, move beyond the idea of a permanently traumatized brain, highlighting physical activity as a modifiable lifestyle factor associated with neurobiological adaptation.

The trillions of microbes living in the human gut are increasingly recognized as important partners in human health. Scientists have linked the gut microbiome to several aspects of health, from metabolism and immunity to mental health.

Colorectal cancer, a type of cancer that affects the colon or rectum, is the second leading cause of cancer-related death and the third most common cause of death or type of cancer. It is the No. 1 cause of cancer-related death for men and women under 50. Roughly one in 24 people will develop colorectal cancer. Though declining in older adults due to screening, cases are rising by nearly 3% per year in adults under 50. While often asymptomatic in early stages, it is highly preventable through screening and highly treatable if detected early.

Hospital stays can be long and arduous; they can also cause serious complications. When a person lies in one position too long and begins to sweat, painful sores called pressure injuries (PIs) can form on the body, leading to infection or even death. A patient can develop a PI in a few days—or even a few hours. And once present, a PI is hard to treat.

Nearly one in five pediatric hospital deaths in the United States involve sepsis, according to a new national study published in JAMA. The study also found that sepsis occurs in about one in every 75 pediatric hospitalizations and that more than one in 10 children with sepsis die during hospitalization. Based on these findings, the authors estimate that more than 18,000 hospitalized children in the United States have sepsis each year, including more than 1,800 who do not survive to discharge.
