Perceived socioeconomic status can affect how old we feel gas and water company


A recent study finds that how older adults perceive their socioeconomic status influences how old they feel and their attitudes toward aging. Specifically, the lower people deem their relative socioeconomic status, the worse they feel about growing older.

A material with atomically thin layers of water holds promise for energy storage technologies, and researchers have now discovered that the water is performing a different role than anyone anticipated. The finding was possible due to a new atomic force microscopy (AFM) method that measures the sub-nanoscale deformation rate in the material in response to changes in the material caused by energy storage.

To slow the evolutionary progression of weeds and insect pests gaining resistance to herbicides and pesticides, policymakers should provide resources for large-scale, landscape-level studies of a number of promising but untested approaches for slowing pest evolution. Such landscape studies are now more feasible because of new genomic and technological innovations that could be used to compare the efficacy of strategies for preventing weed and insect resistance.

Engineering and physics researchers at North Carolina State University have developed a new technology for steering light that allows for more light input and greater efficiency – a development that holds promise for creating more immersive augmented-reality display systems. At issue are diffraction gratings, which are used to manipulate light in everything from electronic displays to fiber-optic communication technologies.

Psychology researchers have used the game League of Legends to advance our understanding of how people build "mental models" – the mental tools that allow people to make use of complex systems. The researchers found that mental models are developed in three distinct stages – findings that have the potential to inform everything from workplace training to video-game development.

Researchers from North Carolina State University have demonstrated a connection between the expression of the HMGA2 gene and body size in pigs. The work further demonstrates the gene’s importance in body size regulation across mammalian species, and provides a target for gene modification.

New research from North Carolina State University and the University of Colorado Boulder finds that steep declines in the use of coal for power generation over the past decade were caused largely by less expensive natural gas and the availability of wind energy – not by environmental regulations.

A recent study finds that young people who get financial support from their parents have greater professional success, highlighting one way social inequality is transmitted from one generation to the next. "The question underlying this work was whether parental support gives adult children an advantage or hinders their development," says Anna Manzoni, an associate professor of sociology at North Carolina State University and author of a paper on the work.

A North Carolina State University study examining the effects of urbanization on the evolution of fish body shape produced both expected and surprising results: One fish species became more sleek in response to urbanization, while another species became deeper bodied in urban areas.
