Tech stocks may still be dropping in markets around the world, but that isn’t because companies are running out of new ideas, to judge from the compilation IEEE Spectrum is publishing here for the third year in a row. Last year inventors and their employers continued to file patent applications at an ever-increasing rate: there were 456 154 applications for U.S. “utility” patents—those for inventions as opposed to design ideas, new organisms, and so on—an increase of 7 percent over 2006. That was more than twice the number filed a decade ago, according to the data compiled by 1790 Analytics, which specializes in evaluating intellectual property.

New Faraday Cages Can Be Switched Off and On

Built out of a novel material called MXene, these cages could block and allow signals as desired

Advanced new Faraday cages—the metal mesh enclosures that can block wireless signals—can also be switched on and off for reversible protection against noise, a new study finds.

In addition, these new shields can be easily fabricated through a technique akin to spray-painting, which could help them find use in electronics, researchers say.

Similarly to the way window blinds adjust how much visible light enters a room, engineers want dynamic control over the electromagnetic waves used in wireless communications. This ability would let devices receive and transmit signals when desired but also protect them against electromagnetic interference, such as static and jamming, and help them avoid being spied on.
