You know how a princess can feel a pea through 20 mattresses and 20 feather beds? Well, not any more. Researchers in Germany have created the first mechanical invisibility cloak. When this cloak is placed over an object, the object cannot be felt at all — either by your finger, or a more sensitive measuring device. This has obvious repercussions for the authentication of fairytale princesses, and also in the realm of camping (die, tree roots, die) and carpeting (cabling begone!)
German researchers have combined photonics and electronics to create a world-record-breaking wireless network that can send and receive data at a heady 100 gigabits per second (Gbps). This beats the same team’s previous world record of 40Gbps. At 100Gbps, or a transfer rate of 12.5 gigabytes per second — ten times faster than Google Fiber — you could copy a complete Blu-ray disc in a couple of seconds.
German material scientists have created the world’s first quantum metamaterial. This new material raises more questions than it answers, but it could have significant applications in the realms of single microwave photon detection and phase switching, and as a vehicle for further investigation of the very principles of quantum physics.
