Cutting Edge

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

When they take over, robots will surely take advantage of studies suggesting we pathetic meatsacks are hardwired to sympathize with them.

Watching a robot being cuddled or abused produces similar reactions in humans to watching people undergo the same treatment, according to two new studies to be presented at the International Communication Association Conference in London in June.

In one, subjects were shown videos in which popular dino-bot Pleo was either hugged or treated violently. Perhaps not surprisingly, the subjects' skin conductance levels rose when Pleo suffered, suggesting they were distressed.

They also reported feeling bad for the bot. Check out how the poor little guy was mistreated in the vid below. … Read more

An interaction designer who makes sci-fi short films has spent the past three years developing what he says is the world's first Braille-enabled smartphone. He said that if testing goes well, the phones could hit stores by the end of this year.

Thanks in part to award money from Rolex, India-based designer Sumit Dagar has been collaborating with the Indian Institute of Technology Delhi and L V Prasad Eye Institute in Hyderabad to develop a prototype. The smartphone employs a haptic touch screen that elevates and depresses the content it receives, thereby transforming the data into touchable patterns.

Yes, this phone is essentially a shapeshifter.… Read more

Would you be more willing to buy a tablet if it had a slick sci-fi promo video? How about something that mixes "The Matrix" with Apple's iconic "1984" Macintosh ad?

That seems to be what Japanese app developer Ubiquitous Entertainment iss shooting for with a series of eerie, dystopian videos titled "Brave New World" that introduce EnchantMoon, a stylus-operated tablet that lets you easily create HTML5 games and apps without programming code. … Read more

Last month at SXSW, SpaceX founder Elon Musk showed off a video of the SpaceX Grasshopper rocket rising 24 stories into the air and returning safely back to the ground. For a vehicle that is 10 stories high, that's pretty good, but not enough to make your jaw drop.

This creation is called the Grasshopper Vertical Takeoff Vertical Landing (VTVL) vehicle. It's so named because of its nifty parlor trick of being able to blast off vertically and then land upright. Now, the company has tripled the distance of the previous attempt and released a new video showing off the rocket's capabilities. … Read more

The 3D printing movement is well under way -- albeit with some hype built in -- and Shapeways, a marketplace where people can design, create, and sell their own products, is leading the charge.

Shapeways, sometimes known as the Etsy for 3D printing, now has 10,000 "shop owners" -- people who have designed products, from iPhone cases to jewelry and shoes, that they print out and sell via Shapeways. The New York-based company is building out its recently opened 3D printing factory in the Queens borough of New York City, where its printers are cranking out roughly … Read more
