The impact of obesity and overweight on the U.S. economy has eclipsed $1.7 trillion, an amount equivalent to 9.3 percent of the nation's gross domestic product, according to a new Milken Institute report on the role excess weight plays in the prevalence and cost of chronic diseases.


Archaeologists find 300,000-year-old stone tools in Saudi Arabia, which at the time was a grassland dotted with lakes. Findings will help anthropologists better understand the role of environment—and the ability to adapt to challenging new landscapes—in shaping human evolution and global expansion.

Adolescents and young adults in the US are most likely to die in June or July, while death rates for those over 45 years old peak between December and February, reveals a study of mortality data from 1980 to 2016.


Bacteria thrive in showerheads and throughout household water distribution systems. New research found that regions in the US where certain lung infections are most common were the same regions where pathogenic mycobacteria were most prevalent in showerheads, highlighting their role in infections.


Children may suffer delayed language skills if their mothers come in contact with common chemicals called phthalates in early pregnancy, new research suggests in JAMA Pediatrics. Phthalates are in countless products from nail polish and hair spray to food packaging and vinyl flooring.
