Near-infrared electrochromism of a new multilayered complex

Researchers have developed a new multilayered complex that displays high-performance near-infrared electrochromism. The complex, prepared by layer-by-layer coordination assembly on metal oxide substrates, exhibits two reversible redox waves and excellent electrochromic performance with a contrast ratio of up to 56% at 1150 nm.

Listening to music while driving reduces cardiac stress

A study by Brazilian researchers found that listening to instrumental music attenuates cardiac stress while driving, increasing parasympathetic nervous system activity and reducing sympathetic nervous system activation. This can contribute to the creation of cardiovascular preventative measures for situations of acute stress.

Study suggests interventions against frailty

Interventions aimed at reducing obesity, sedentary behavior, smoking cessation, and improving physical activity have the potential to delay or reduce frailty. Age is a strong predictor of frailty, with other variables such as modifiable risk factors like obesity and lower body strength also being significant risk factors.
