Cutting Edge

While it might look like a giant robotic pet, scientists at the Georgia Institute of Technology have actually created the "FlipperBot" to generate new data on how organisms move.

The robot mimics the movements of sea turtle hatchlings struggling to reach the ocean. These little creatures need to rely on dexterity and flexibility in their wrists to get around without moving a lot of the surrounding sand.

"We are looking at different ways that robots can move about on sand," Daniel Goldman, an associate professor at the Georgia Institute of Technology, said in a statement. "We wanted to make a systematic study of what makes flippers useful or effective. We've learned that the flow of the materials plays a large role in the strategy that can be used by either animals or robots."… Read more

We've always been told not to stare at the sun, but NASA's Solar Dynamics Observatory (SDO) has been doing just that for the last three years. Since it started operations, the SDO has taken a shot of the sun using its Atmospheric Imaging Assembly every 12 seconds on 10 different wavelengths, giving scientists an unprecedented look at the shifting moods and surface of our nearest star.

NASA put together a 3-minute video of the sun's last three years and set it to lovely music. The result is a yellow, fluctuating, spinning globe, spitting out flares over time. It's nearly hypnotizing.… Read more

Alexander Graham Bell is known for inventing the telephone; but for someone so associated with sound, it's curious that no one living has actually ever heard the tenor of his voice.

However, as of Wednesday, anyone can hear what he sounded like. New technology has brought a 128-year-old recording made by Bell back to life, according to Smithsonian magazine.

The artifact, a wax and cardboard disc, has most likely been unplayable for at least a century. According to Smithsonian, Bell worked on several different ways to record sound, including using foil, wax, glass, paper, plaster, metal, and cardboard. Not … Read more

With watches, glasses, and clothing that can double as tech devices, it seems like wearable inventions are only going to continue to proliferate.

How about wearable technology that can read a person's muscle movement and then use that data to control other devices?

This is something that Thalmic Labs has been working on for the past year. The company explained the project in detail in a video released Wednesday.

Dubbed the MYO, this one-size-fits-all armband is a remote control of sorts. When worn on the body, it instantaneously reads the electrical activity of the muscles to track the movement … Read more

Don't you just love looking at luxury items you'll never be able to afford? The timepieces on display at Swiss watch fiesta Baselworld can carry price tags that will give you a nosebleed, but they also showcase stunning feats of craftsmanship.

Baselworld 2013 opens to the public Thursday, and aside from the oodles of gorgeous timepieces, the 41st edition of the fair is showing a glittering new exhibition hall redesigned by architects Herzog & de Meuron, who did Beijing's famous "Bird's Nest" arena.

Luxury brands from Hermes to TAG Heuer have swanky booths designed by prominent architects such as Japan's Toyo Ito, winner of the 2013 Pritzker Prize.

It's all to present the world's greatest watches in their best light. … Read more

Comet ISON, discovered in September of last year by Russian Vitali Nevski, is headed in our direction. And although the sungrazing comet is still more than 394 million miles away (a little closer than Jupiter's current orbit), NASA's Hubble telescope managed to capture an amazing photograph on April 10.

NASA believes that when ISON is at its closest point to the sun on November 28 of this year, it will briefly become brighter than the moon in the sky, making it a serious contender for "comet of the century."

Currently, the comet is headed toward the sun at a speed of around 47,000 miles per hour and has a dusty head of around 3,100 miles wide (about 1.2 times the width of Australia). Its tail trails more than 57,000 miles behind. And yet, the core of the comet's head is tiny -- no more than around 3 to 4 miles across. … Read more

Sony, trying to bring digital technology to a market that's remained stubbornly analog, has upgraded its digital binocular with the announcement today of the $2,000 DEV-50V.

The binoculars, due to ship in June, are vastly more expensive than even high-end binoculars from rivals such as Canon and Nikon. But Sony's digital binoculars -- which capture a scene with image sensors then display it with small electronic viewfinder (EVF) -- can do something ordinary binoculars can't.

Namely, they'll help you remember what you saw by taking a video or photo. And, if you like, it'll … Read more

If I had a dime for every time someone writes "I, for one, welcome our new robot overlords," I'd have enough money to bribe my future robot master into sparing me from the meatsack ghettos.

Our dystopian robot future is always good grist for lame jokes. Unless it might actually happen.

Human Rights Watch seems very serious about a new campaign it has launched against what it calls "killer robots." … Read more

NEW YORK--For months, a debate has raged in the media and on Capitol Hill about whether or not society (and the law) should allow 3D-printed guns.

After listening to Cody Wilson speak for a few minutes, one can't help but come away feeling that the national discussion is moot: 3D-printed firearms are inevitable.

Today at the Inside 3D Printing Conference and Expo, Wilson, the founder and director of Defense Distributed, argued for an environment in which people can use 3D printers to make guns.

It's not that he doesn't recognize -- or care -- that there's … Read more
