Want to make sure you back something up indefinitely? Then you could do worse than a digital data storage technique that uses laser light to store 360 terabytes of information on nanostructured quartz for up to 14 billion years.
I'm pretty sure I'm not the only one who did this, but the first thing I did when I got my first laser pointer was go outside and point it at the moon. I'd stare and wonder if someone was up there, would they be able to see the little red light shining from the Earth?

Scientists at Yale University have created the world's first anti-laser, a device in which two beams of light clash together, ultimately cancelling each other out. How could such a device change the way we do our computing?
