A new study published in the journal Psychological Science found that people who feel enthusiastic and cheerful — what psychologists call “positive affect” — are less likely to experience memory decline as they age. This result adds to a growing body of research on positive affect’s role in healthy aging.

A team of researchers analyzed data from 991 middle-aged and older U.S...

Researchers at Los Alamos National Laboratory and their collaborators from the University of California, Irvine have created fundamental electronic building blocks out of tiny structures known as quantum dots and used them to assemble functional logic circuits. The innovation promises a cheaper and manufacturing-friendly approach to complex electronic devices that can be fabricated in a chemistry laboratory via simple, solution-based techniques, and offer long-sought components for a host of innovative devices.

“Potential applications of the new approach to electronic devices based on non-toxic ...

An instrument on NASA’s Juno mission spacecraft may have detected transient luminous events – bright flashes of light in the gas giant’s upper atmosphere.

New results from NASA’s Juno mission at Jupiter suggest that either “sprites” or “elves” could be dancing in the upper atmosphere of the sola...

According to the American Heart Association, heart disease is the leading cause of death worldwide in recent years. During a heart attack, or myocardial infarction (MI), a blocked artery and the resulting oxygen deprivation cause massive cardiac cell death, blood vessel impairment and inflammation. Now, researchers reporting in ACS Biomaterials Science & Engineering have developed a cardiac patch with tiny engineered blood vessels that improved recovery from MI in rats and pigs.

To effectively treat MI, lost heart muscle tissue must regenerate and new blood vessels must form to restore oxygen and nutrients to cells...
