Mysterious iron ‘bar’ discovered in famous nebula

A team of astronomers at Cardiff University and UCL discovered a mysterious bar-shaped cloud of iron atoms inside the Ring Nebula, which is roughly 500 times longer than Pluto's orbit. The discovery was made using a new instrument on the William Herschel Telescope, allowing for unprecedented detail in observations of the nebula.

Learning about public consensus on climate change does little to boost people’s support for action, study shows

A new study based on data from Germany found that learning about widespread public support for climate action policies initially makes people think such policies are more politically feasible, but these effects are small and short-lived. The study challenges common expectations about the power of public consensus to drive climate action.

With telehealth coverage on the brink, study shows it hasn’t driven up total visits

A recent University of Michigan study analyzed over 60 million Medicare participants and found that total visits remained stable or declined slightly through June 2024. Despite widespread adoption of telehealth, overall healthcare visits stayed steady or decreased, contradicting predictions of increased utilization.

History offers warning on dollar and deficits

A new study warns that the U.S. government's fiscal capacity depends on the dominance of the U.S. dollar, and potential losses for bondholders could be significant if another currency replaces it. Historically, countries with a strong currency have experienced economic downturns when their dominance wanes.

Review: The opportunities and risks of AI in mental health research and care

The article reviews AI's potential to improve mental health diagnoses, monitoring, and treatment while addressing unique challenges such as biased training data and patient privacy concerns. The authors argue for human-centered approaches and coordinated oversight to ensure responsible AI deployment in mental health care.

Novel theranostic model shows curative potential for gastric and pancreatic tumors

A newly developed radiopharmaceutical pair can precisely detect and effectively treat gastric and pancreatic tumors, completely eradicating tumors in preclinical models. Claudin-18.2-based theranostics could meaningfully change patient care by enabling non-invasive tumor identification and targeted radiation therapy.

Parental concerns about child disordered eating common among youth with high weights in behavioral intervention

A new study in the Journal of Nutrition Education & Behavior found that nearly half of parents of young children with high weights reported concerns about disordered eating behaviors. Despite the intervention, parental concerns did not change over time, suggesting a protective effect of motivational interviewing.

New analysis of wellbeing interventions shows there are multiple routes to better mental health

A new analysis of wellbeing interventions shows that there is no single route to improving mental health, with mindfulness, compassion-based approaches, yoga, exercise and positive psychology interventions all showing moderate benefits. Combining physical activity with psychological interventions appeared particularly promising.

Many drug-use treatment providers in N.C. demand unpaid labor, limit access to evidence-based treatment

A new study in NC found that many residential substance-use service providers require patients to engage in unpaid labor, restricting access to evidence-based treatment. Providers with labor requirements are less likely to offer recommended treatment and more likely to operate without a state license.
