'Superlens' extends range of wireless power transfer

Inventor Nikola Tesla imagined the technology to transmit energy through thin air almost a century ago, but experimental attempts at the feat have so far resulted in cumbersome devices that only work over very small distances. But now, Duke University researchers have demonstrated the feasibility of wireless power transfer using low-frequency magnetic fields over distances much larger than the size of the transmitter and receiver.

Superlens could put high-powered microscope in your pocket

Cellphones could soon contain an ultra-high-resolution microscope alongside the ubiquitous camera, thanks to a breakthrough by Michigan Technological University professor Durdu Guney.
