World's smallest spirals could guard against identity theft

Take gold spirals about the size of a dime…and shrink them down about six million times. The result is the world's smallest continuous spirals: "nano-spirals" with unique optical properties that would be almost impossible ...

What makes Mars sunsets different from Earth's?

Even robots can't tear their eyes from a beautiful sunset. NASA's Mars Curiosity rover pointed its high resolution mast camera at the setting sun to capture this 4-image sequence on April 15 at the conclusion of the mission's ...
