    Could A Tattoo Help You Stay Healthy?

    Could A Tattoo Help You Stay Healthy?

    Can we make tattoos both beautiful and functional? Nanotechnologist Carson Bruns shares his work creating high-tech tattoos that react to their environment -- like color-changing ink that can tell you when you're getting a sunburn -- and shows exciting ways they can deliver real-time information about our health.

    The science of skin - Emma Bryce

    The science of skin - Emma Bryce

    Between you and the rest of the world lies an interface that makes up 16% of your physical weight. This is your skin, the largest organ in your body: laid out flat, it would cover close to 1.7 square metres of ground. But besides keeping your organs in, what is its purpose? Emma Bryce takes us into the integumentary system to find out. Lesson by Emma Bryce, animation by Augenblick Studios.
