Drug delays type 1 diabetes in people at high risk

Researchers found that an immunotherapy treatment, teplizumab, effectively delayed the progression to clinical type 1 diabetes in high-risk individuals. Participants who received teplizumab took longer to develop clinical disease, with a median time of 48 months compared to just over 24 months for those in the control group.

How do foams collapse?

Foam collapse occurs via two distinct mechanisms: 'propagating' mode, where a film is absorbed into the surrounding liquid, and 'penetrating' mode, where droplets release from a rupture event break other bubbles. Understanding these mechanisms can help tailor foams to specific applications.

Solved: How tides can trigger earthquakes

Researchers discovered that tidal fluctuations cause the magma chamber to expand, forcing the lower block of earth to slide up the fault, resulting in earthquakes. Even small stresses can trigger tremors, making it difficult to predict when an earthquake will occur.

AI tool helps radiologists detect brain aneurysms

A new AI tool developed by researchers at Stanford University improves clinicians' ability to correctly identify brain aneurysms by highlighting areas of interest on scans. The HeadXNet algorithm reduces the 'miss' rate and increases consensus among clinicians, with promising results but further investigation needed.

Costs of care similar or lower at teaching hospitals compared to non-teaching hospitals

A new study by Harvard T.H. Chan School of Public Health found that teaching hospitals have similar costs to non-teaching hospitals for common medical conditions, with lower costs for follow-up care and readmissions. The findings suggest a reevaluation of the relationship between teaching hospital costs and patient outcomes.

When social interaction helps you choose your food

Studies using rodents demonstrate how sensory stimuli linked to social contacts modify neural connections involved in food choice, highlighting the importance of social transmission of food preferences. This mechanism may be deficient in individuals with autistic disorders, contributing to their social difficulties.
