Researchers have "cloaked" a three-dimensional object, making it invisible from all angles, for the first time.
However, the demonstration works only for waves in the microwave region of the electromagnetic spectrum.
It uses a shell of what are known as plasmonic materials; they present a "photo negative" of the object being cloaked, effectively cancelling it out.

The chance of a big earthquake hitting the Japanese capital in the next few years is much greater than official predictions suggest, researchers say.
The team, from the University of Tokyo, said there was a 75% probability that a magnitude seven quake would strike the region in the next four years.The government says the chances of such an event are 70% in the next 30 years.

The European Space Agency have managed to communicate with the Russian probe: Phobos-Grunt. The probe was built to land on the larger of Mars' two moons, Phobos, and scoop up rock to bring back to Earth. The ESA have managed to contact the probe with partail success (http://www.bbc.co.uk/news/science-environment-15872653).
