My Quest To Analyze Every Man-Made Chemical In My Body

Every day we're exposed to thousands of man-made chemicals, some of which seep into our bodies and remain there for decades. What that means for our health, we don't fully understand--but I subjected myself to a battery of new tests in search of answers

Let’s start with the bad news: You are saturated with man-made chemicals, some of them toxic. Today’s exposure began when compounds in your shampoo and shaving cream seeped into your skin cells, and during your morning coffee, when you drank chemicals that were released into your brew as hot water ran against the plastic walls of your coffeemaker.

In the future, signs will be instantly rewritable and walls will change color at the flip of a switch. A research team at the University of California at Riverside has created a new magnetically activated, instantly and reversibly color-changing material with potentially groundbreaking applications. The technology is based on that used by colorful birds, beetles, and butterflies: instead of static pigments, the material employs "structural color," which depends on the interference effects of light.
