Turbulent environment set the stage for leaps in human evolution and technology 320,000 years ago

A new environmental record for a prehistoric site in Kenya helped researchers figure out how external conditions influenced which of our ancient ancestors lived there, with what way of life.

Remembering Mario Molina, Nobel Prize-winning chemist who pushed Mexico on clean energy -- and, recently, face masks

Molina, who died on Oct. 8, 'thought climate change was the biggest problem in the world long before most people did.' His research on man-made depletion of the ozone layer won the 1995 Nobel Prize.
