Calcite deposit from southern Nevada cave reveals 580,000 years of climate history

A calcite deposit in a southern Nevada cave has provided new insight into the region's hydroclimate, revealing significant shifts in temperature and rainfall over the last 580,000 years. The analysis suggests that temperature, availability of water, and vegetation are tightly coupled, with changes in one area impacting others.

New study shows Q&A-style messaging can increase public health engagement and information seeking

Researchers found that question-and-answer messaging significantly increased curiosity, topic-specific information seeking, and in some cases promoted healthier behaviors. In controlled experiments with over 49,000 participants, Q&A messages led to increased self-reported adherence to protective health behaviors.

Children’s Hospital of Philadelphia researchers identify genetic factors influencing bone density in pediatric patients

Researchers at Children's Hospital of Philadelphia have identified four genes linked to osteoblasts and their ability to mature, which can affect bone mineral density. A polygenic risk score called genetic quantitative ultrasound speed of sound (gSOS) was also found to be associated with higher bone mineral density and reduced odds of ...

Solving a 70-year-old medical mystery surrounding a vasodialator may yield a novel way to treat brain cancer

A team at the University of Pennsylvania has solved the mechanism of action of hydralazine, revealing its potential to halt the growth of brain cancer cells. By blocking an oxygen-sensing enzyme, hydralazine can reduce intracellular calcium levels, causing blood vessels to relax and tumor cells to enter a dormant state.
