It's all just skin deep. An anthropologist explains in a video how she used UV radiation data from NASA to come up with a theory on how human skin color has evolved over time. The skin has to be dark enough to block harmful UV radiation,...

Bask in the glow of an illuminating resource. Young scientists learn how sunlight is an ubiquitous carcinogen. The engaging video in the ACS Reactions series describes the effects ultraviolet radiation has on the human body.

How can light be both a particle and a wave? With characteristics of each, the idea of light can be confusing. A lesson in the Crash Course physics series introduces scholars to quantum mechanics and how scientists use it to understand...

Is all radiation harmful? The video's narrator interviews unsuspecting citizens to get their take on radiation sources and effects. The resource includes a breakdown of types of radiation and whether each type is capable of causing us harm.

The Greenhouse Effect is a big part of why Earth is able to sustain life. But, how much is too much? In part two of an eight-part series about the carbon cycle, environmental scholars learn how the natural Greenhouse Effect keeps us warm...
