Diving for Coral-bots to repair the world's dying reefs

Head underwater at the Great Barrier Reef with Google Maps, and you'll notice something deeply saddening: instead of the vividly colored corals you would expect, vast swathes of the reef are dull brown -- dying, thanks to pollution, fishing, and climate change. This is a situation repeated the world over, with 20 percent of the world's reefs dead, and another 50 percent under immediate threat.

Although coral reefs, when left alone, can regenerate, those closer to human habitation aren't so lucky. It seems hopeless; short of drastic intervention, such as the cessation of fishing and dropping waste into the sea, how on earth could we combat this?

Humans have been trying to help. Fragments of Hope is a coral nursery in Belize that sends divers down to plant pieces of healthy coral in the dying reefs to speed up the recovery process. This work is painstaking and slow, however, and -- perhaps most pertinently -- subject to the limitations of the human body. There are places where humans cannot dive, and human endurance has a limit.

The Coral-bot Team from the U.K. has proposed that robots go where humans can't tread. The team has designed and built a series of robots that could autonomously navigate the depths and continue the work of planting coral. … Read more

New moms more likely to seek help for depression if it's online

Postpartum depression afflicts between 10 percent and 15 percent of new moms. But with some never seeking help, those numbers may be even higher. And in a new study out of Case Western Reserve, researchers found that many women don't seek counseling because of the stigma attached to depression and because they feel they simply don't have the time -- but they would go online for help if professionals were available and they could remain anonymous.

"Mothers cannot always find a sitter and then spend time driving to and from counseling," Judith Maloni, lead investigator and … Read more

NASA experimenting with 3D printing for space exploration

NASA is getting into the 3D printing business. At NASA's Ames Research Center, engineers and researchers are experimenting with the technology with the hope that one day their creations will be used in space exploration. "Space Shop is our attempt to take the best practices and lessons learned from what we call the maker community," said Dave Korsmeyer, the director of engineering at NASA Ames.

The program is still in its nascent stages. But NASA sees potential in the technology because it enables designers and engineers to get the manufacturing information early in the design process and … Read more

Reading on treadmill no sweat with ReadingMate

No diversion can divert me from the fact that treadmills are boring. Even if the weather is bad, I'm not much of a TV viewer -- on or off the treadmill. And I often find the most energizing music to also be the most annoying. Reading on a treadmill can be downright nauseating.

But thanks to an experimental system out of Purdue University, I soon may be able to catch up on my backlog of New Yorker digital issues while clocking time on the dreaded tread.… Read more

LG voice-activated vacuum robot does your cleaning bidding

We all know what Roombas are good for. They're good for ferrying cats around, dressing up in silly costumes, and occasionally sucking up dirt. One thing they're not good for, however, is bossing around. For that, you'll need the new Roboking vacuuming robot, which LG announced for the Korean market.

The new Roboking pretty much looks like its predecessors, but it's got more going on under the hood. It takes voice commands and can recognize which direction a person's voice is coming from. That means you could stand at the site of a particularly heinous dirt pile and call it over to come clean it up.… Read more

Leap Motion strikes bundling, embedding deal with HP

Leap Motion has struck a deal with Hewlett-Packard to bundle and embed its 3D motion control technology in some of the computer giant's devices.

The San Francisco startup's gesture-control system measures users' movements to an accuracy of a hundredth of a millimeter. It plans to release the technology in mid-May, charging $80 for a small thumb drive-size device that plugs into a computer's USB port.

Already, Leap Motion had cemented deals to bundle its controller with Asus PCs, and to sell it in Best Buy stores and at Bestbuy.com, as well as on its own Web … Read more

Eric Schmidt: Regulate civilian drones but not Google Glass

At some point in the not-too-distant future, the skies could be filled with drones -- swarms of insect-size and larger drones hovering over neighborhoods, alleyways, and even inside bedrooms.

That's a nightmare future, according to Google's Eric Schmidt. In an interview with the Guardian, he said. "You're having a dispute with your neighbor. How would you feel if your neighbor went over and bought a commercial observation drone that they can launch from their backyard? It just flies over your house all day. How would you feel about it?"

Following the proliferation of mini-drones, someone … Read more

Working kidney created in bioengineering lab

There just aren't enough donated organs to fill the need. That's why scientists have been dreaming of growing transplantable organs in labs. Scientists at the Massachusetts General Hospital Center for Regenerative Medicine have made a step forward by creating a functional rat kidney.

The process is not quite as futuristic as growing a whole organ from scratch. Researchers started with kidneys from dead rats and used a special soap-cleaning process to scrub away the cells. Essentially, this gave them a foundation of a kidney to work with, a blank canvas.… Read more

Construction of world's largest optical telescope approved

If you love eye-popping images of space, here's welcome news: the Hawaiian Board of Land and Natural Resources has backed building what's to be the world's largest, most powerful optical telescope above the clouds atop the volcano Mauna Kea.

The Thirty Meter Telescope (TMT) will have a primary mirror of 492 segments measuring some 100 feet across, giving it the power to image objects 13 billion light years away, near the beginning of the universe.

It may also photograph planets outside our solar system with unprecedented detail. … Read more

Boeing's futuristic X-48C makes final flight

It's mission accomplished for the experimental X-48C aircraft.

The distinctively shaped machine this week made the last of 30 flights in an eight-month program as backers Boeing and NASA sought to show how well a "blended wing body" aircraft can perform. The X-48C program is tied to NASA's Environmentally Responsible Aircraft project, which is geared toward developing futuristic airplanes that burn less fuel, spew fewer emissions, and make less noise.

The Boeing-designed X-48C has a radically different look than that of conventional aircraft. Where a big 747 or a little Cessna has -- very roughly speaking … Read more
