In a study of 5- to 11-year-olds in the United States and China, the authors found that children’s belief that their family and friends would support their pursuit of political leadership as adults predicted their expressed motivation to become political leaders—specifically, “president” for children in the US and “chairman” for children in China. In both countries, this relationship was particularly strong for girls compared to boys.

n a new longitudinal study, researchers examined EU and U.S. news and media websites to determine how online content providers adapted their responses to the GDPR over time, and whether restrictions on online tracking affected outcomes such as the quantity of content and visitors’ engagement. The study found that while EU websites made changes and adapted, they continued to produce quality content and engage audiences at levels comparable to their U.S. counterparts.

George Mason University faculty member Y. Alicia Hong, a digital behavioral health interventionist, will support older adults in honing their digital technology skills. The program, through an interdisciplinary partnership, will pair youth and older adults to practice real-life AI scenarios.

A poll of older adults looks for signs of addiction to ultraprocessed foods and drinks, and finds especially high rates among those in their 50s and early 60s who were children and teens during the 1980s when the nation's food environment changed.

Gravitational-wave detection technology is poised to make a big leap forward thanks to an instrumentation advance led by physicist Jonathan Richardson of the University of California, Riverside. A paper detailing the invention, published in the journal Optica, reports the successful development and testing of FROSTI, a full-scale prototype for controlling laser wavefronts at extreme power levels inside the Laser Interferometer Gravitational-Wave Observatory.
