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

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

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

Study: Anxiety and alcohol use linked to Facebook

In a quest to learn what leads some people to turn to Facebook to connect with others, doctoral student Russell Clayton of the Missouri School of Journalism found that anxiety and alcohol use seem to play a big role.

For his master's thesis, which appears in the May issue of Computers in Human Behavior, Clayton surveyed more than 225 college freshman about two emotions, anxiety and loneliness, and two behaviors, alcohol and marijuana use. He found that the students who reported both higher levels of anxiety and greater alcohol use also appeared the most emotionally connected with Facebook. Those … Read more

LED lights could become network devices, too

Today, you've got wireless networks that use radio waves and you've got optical networks that use light traveling in tiny glass fibers. Tomorrow, if Fraunhofer Institute research comes to fruition, a combination of the two could turn living-room lights into network devices.

The German applied-research lab has developed wireless networking that uses rapidly blinking LEDs to transmit data through the air. The technology can send data at speeds up to 1 gigabit per second -- and by using three colors of light, triple that data rate is possible, Fraunhofer said.

The technology could be useful in crowded, interference-prone … Read more

Innovation and re-invention at the Stanford Cool Product Expo

STANFORD, Calif. -- Finding a new product idea is never easy. You have to understand your target audience and test the market. But not every new product comes from a new idea -- sometimes the best products are simply new ways of viewing the world, or new approaches to old problems.

At the Cool Product Expo held at Stanford University this week, a few of the designs on hand are re-imagining some classic products -- in ways you might never have thought possible.

One company, Impossible, is hoping to revive instant photography, and dozens of other companies -- 11 of … Read more
