The study found that adhering to these healthy behaviors reduced the risk of major cardiometabolic diseases independent of medication use.
Researchers have developed a new method for cleaning oil spills using massive fire whirls, which can burn through crude oil nearly twice as fast as in-situ fire pools. The results show that fire whirls produce 40% less soot and consume up to 95% of the fuel, leaving fewer harmful particles behind.
A cohort study of 47,000 adults found that males had a 63% greater risk of all-cause mortality compared to females after adjusting for demographic and behavioral factors. The study suggests intrinsic biological factors, such as sex hormones or immune response, may contribute to these sex differences in mortality.
