Bomb jammer

A US inventor has patented a way to defeat remote-controlled explosives by creating a bubble of radio frequency noise to prevent terrorists from sending a trigger signal to a hidden bomb. The New Scientist says that existing radio jamming devices are flawed because they leave gaps that let trigger signals sneak through. The new system, however, uses four radio transmitters that produce a bomb-blocking bubble up to one square kilometre around a risk area.

Smart ‘rabbit’

The term “rabbit ears” may bring to mind television in the before-the-cable era, but a brand-new electronic bunny adjusts its own ears. Arriving this month from the French company Violet, the Nabaztag Wi-Fi Smart Rabbit is a nine-inch talking pet that hops onto the user’s home network to read the news, weather, text messages and many more things. It can even signal by moving its ears, the New York Time reports. “The idea behind this product was to create a new generation of stuff completely independent of the PC,” a spokesman of the French company said.
