Metamaterials are a new class of artificial substances with properties unlike anything found in the natural world. Some have been designed to act as invisibility cloaks; others as superlenses, antenna systems or highly sensitive detectors. Now, researchers at MIT and elsewhere have found a way to use metamaterials to absorb a wide range of light with extremely high efficiency, which they say could lead to a new generation of solar cells or optical sensors.

Researchers have developed a new class of materials that can readily and efficiently absorb carbon dioxide from a smokestack or even directly from the atmosphere. The substances can help alleviate problems associated with carbon dioxide emissions , like climate change and ocean acidification. [More]
