In the pursuit of stronger, cleaner, and altogether better materials, scientists are turning to Mother Nature for inspiration. Biomimicry (literally "imitating life") is a field of science that studies naturally occurring processes and designs and looks for ways to mimic them. In this slide show, see some of the amazing structures and properties that animals and plants have evolved, and learn about new human-made super-materials they are giving rise to.
The Stuff of Smartphones
See the materials and technologies that go into a smartphone as well as their environmental impact.
Invisibility cloaks. Spider silk that is stronger than steel. Plastics made of sugar that dissolve in landfills. Self-healing military vehicles. Smart pills and micro-robots that zap diseases. Clothes that monitor your mood. What will the future bring, and what will it be made of?
Get a behind-the-scenes look at scientific innovations ushering in a new generation of materials that are stronger, smaller, cleaner, and smarter than anything we've ever seen.
Can innovations in materials science help clean up our world? In "Making Stuff: Cleaner," David Pogue explores the rapidly developing science and business of clean energy and examines alternative ways to generate it, store it, and distribute it.
Is hydrogen the way to go? What about lithium batteries? Does this solve an energy problem or create a new dependency? Pogue investigates the latest developments in bio-based fuels and in harnessing solar energy for our cars, homes, and industry in a program full of the stuff of a sustainable future.
