Compulsive smartphone habits in older adults can be linked to a higher risk of depression, according to a study led by a Rutgers researcher. 

Researchers said their findings raised concerns that technology widely promoted to build connections can instead deepen late-life isolation: While mobile devices can be invaluable lifelines, their impact on mental health depends heavily on the way people use them. A critical distinction, the researchers said, is whether someone uses technology to actively engage with the world or to withdraw. 

“It comes down to purposeful interaction versus compulsive escapism,” said Chien-Chung Huang, a professor at the Rutgers School of Social Work and a senior author of the study. “The same device can bridge the gap to loved ones and community or serve as a wall to shut them out.”

Electric vehicle batteries could last twice as long, preventing costly replacement, with a new approach to heating and cooling the batteries, according to a study led by University of Michigan Engineering. 

The system is designed to work with voltage and charging data that today's battery management systems already collect, rather than requiring new sensors inside the battery. It is best suited for lower-power Level 1 and Level 2 charging, which is common at homes, workplaces and public parking areas, and is expected to cover most EV charging demand.

A study examining air quality and respiratory health in communities surrounding the Salton Sea in Southern California shows how environmental conditions, poor housing quality, and structural inequities combine to place children at greater risk for respiratory illness.
