Wood, Cellphone, Silence

Japanese researchers have developed a magnetic wooden laminate that could prevent people using wireless devices in theaters, restaurants, and other public places, according to an article in U.K. magazine New Scientist. The ferrite and cider-wood composite has been found to block cellphone calls and Bluetooth and WiFi data connections, potentially squelching the consistent background hum of "But honey, I'm at the restaurant already" so prevalent in eateries around Unstrung's New York offices.

Hideo Oka and a team of electronics engineers at Iwate University in Morioka, northern Japan, developed the wood composite. They reckon it could also be useful in cutting interference between separate wireless LAN implementations.

Certainly, blocking phone calls in concert halls and restaurants could save a few black eyes and broken ribs.
