Discovery could provide environmentally friendly way to purify water contaminated by mining activity, say researchers.
The most common materials in the world, including plastic, steel, glass or wood have distinct molecular and chemical properties that give them intrinsic qualities, such as strength, flexibility or transparency. But an entirely different class of materials, called metamaterials, are coming onto the scene.
Artificially engineered, these materials have unique geometries and physical structures that can manipulate any mechanical or electromagnetic wave that passes through them. Metamaterials can perform a host of futuristic tricks; they can absorb sound waves to produce silence, bend light to create an invisibility cloak and dampen seismic waves to safeguard a building against an earthquake.
Metamaterial applications are numerous, but here are five of the coolest.

CENTENNIAL, Colo. (KDVR) — Gov. Jared Polis issued a statewide stay-at-home order Wednesday afternoon. It goes into effect 6 a.m. Thursday and will last until April 11.
Many Coloradans, including the vast majority of people in metro Denver, live in counties where stay-at-home orders have already been announced.
Polis said he is issuing the order to save Coloradans’ lives.
[Isolation is] actually very doable, but it’s very important to be able to interact well with the people you’re staying with, living with.
