Behind many of today’s most compelling issues—obesity, climate change, veterans’ health, understanding the universe to name just a few—is a wealth of information gleaned from science, engineering, and medicine. These scientific underpinnings help us make sense of complicated topics, offering insights into how to move forward in our daily lives.

The Science Behind It, a project of the National Academy of Sciences, features questions people are curious about. It tells the story of why each topic is important and what current science tells us about it. Designed with everyday people in mind, the project highlights the ways science, engineering, and medicine touch our lives every day.

The National Academy of Sciences is a private, non-profit society of distinguished scholars. Established by an Act of Congress, signed by President Abraham Lincoln in 1863, the NAS is charged with providing independent, objective advice to the nation on matters related to science and technology.
