Health insurance coverage is associated with lower odds of alcohol use by pregnant women

A study published in the journal Drug and Alcohol Dependence found that pregnant women with health insurance coverage had lower odds of alcohol use, while non-pregnant women with insurance had higher odds. The study also found that prenatal substance use poses significant threats to maternal and child health.

Health-eBrain study to launch phase II

The Health-eBrain Study launches Phase II to investigate the impact of Alzheimer's caregiving on brain and behavioral health. An international cohort of caregivers will use a mobile app to assess their cognitive function over 12 weeks, tracking stress levels, sleep, mood, and self-evaluation of memory.

Japanese tadpoles relax in hot springs

A recent study by Hiroshima University scientists found Japanese tadpoles can live and grow in natural hot springs with water temperatures up to 46.1°C. This unique adaptation may allow the species to thrive on small volcanic islands with limited fresh water sources.

The hot attraction of gold

Researchers at Tohoku University have discovered that gold can be magnetized by applying heat. The non-equilibrium anomalous Hall effect (nAHE) was observed in the gold film due to the heat flow, indicating the evolution of magnetization. This discovery has potential applications in thermoelectric devices and spintronics.
