Technology & Digital Life

Many people think 3-D printing could help spark a manufacturing renaissance in the U.S. — even President Obama highlighted this technology in his State of the Union address last week.

But as 3-D printers and 3-D scanners get cheaper, this nascent industry could be roiled by battles over intellectual property.

Not so long ago, a good 3-D scanner that could create accurate digital models of objects in the real world cost more than $10,000. Then, Microsoft released the Kinect — the video game controller that allows you to play games by just waving your hands.

It sounds like something out of a spy movie: A new app called Silent Circle allows users to "burn" sensitive messages sent on their phones.

Jon Callas, one of the people who developed the app, says the idea is pretty simple.

"It's a timer. So you can say, one hour; seven minutes. Whatever," Callas tells Jacki Lyden, host of weekends on All Things Considered.

It's called a "burn notice." When the time's up, the text is erased from both the sender and receiver's phones.

IRA FLATOW, HOST:

Flora Lichtman's here, switched hats again.

FLORA LICHTMAN, BYLINE: Switching gears.

FLATOW: Switching gears, and our gear is our Video Pick of the Week, and it's a real - as always, a real cool one.

LICHTMAN: This one, yeah, very cool. We're to the earthly pleasures now - part - segment of the show. It's about art. We went and visited the studio of artist Toni Dove, and she makes the art - the kind of art that's just my style. It satisfies my craving for fantasy, and also my real nerdy, geeky side.

A future without weeds would be a kind of farmer utopia, but currently, herbicide-resistant "superweeds" are part of today's reality. Some researchers, though, are looking for a solution that seems ripped from science fiction: weed-seeking robots.
