Printable bionic ear sends hearing to the dogs

Using off-the-shelf 3D printing tools, silver nanoparticles, and cell culture, scientists at Princeton University have created a functional bionic ear that can detect radio frequencies far beyond the normal human range.

Living, 3D-printed tissue has been in the news a fair bit recently, but this is the first attempt at creating a fully functional organ with embedded electronics.

"In general, there are mechanical and thermal challenges with interfacing electronic materials with biological materials," said Michael McAlpine, an assistant professor of mechanical and aerospace engineering at Princeton and the lead researcher on the project. "Previously, researchers have suggested some strategies to tailor the electronics so that this merger is less awkward. That typically happens between a 2D sheet of electronics and a surface of the tissue. However, our work suggests a new approach -- to build and grow the biology up with the electronics synergistically and in a 3D interwoven format." … Read more

A better button-down? Entrepreneur promises self-cleaning shirt

A new shirt being touted as "the better button-down" aims to make laundry as we know it a thing of the past. The entrepreneur behind it claims it never wrinkles and can be worn over and over, without being washed.

Marketing grad Mac Bishop, 24, says his shirt not only looks good, but is soft to the touch, resistant to wrinkling, and odor-free. To prove it, he wore one of the shirts for 100 days in a row without washing it.

"I've (run) 4 miles in this shirt, I've biked 5 miles in this shirt, I've thrown it on after a basketball game," Bishop told CBS News. "It airs out. It's the miracle fiber." … Read more

Bug-eyed! This digital camera tech gives 180-degree view

A team of researchers at several universities around the world has created a new digital camera technology that takes cues from bug eyes.

The technology, which has not yet been named, is designed after the eyes found in arthropods. The camera is equipped with a a slew of image sensors and focusing lenses around a hemispherical base. With the sensors arranged in that way, the camera can take complete 180-degree pictures with no interpretive mistakes in image quality.… Read more

NASA's Fermi telescope dodges a 3,100-pound bullet

The near miss that happened with a high-tech telescope orbiting the Earth last month was so dramatic that I have to assume Hollywood thrill makers will soon be calling up NASA project scientist Julie McEnery to get all the details and begin determining how feasible it is to jam Ben Affleck or Morgan Freeman into the story line.

McEnery works with NASA's Fermi Gamma-ray Space Telescope, which has the mission of mapping the highest-energy light in the universe. On March 29, McEnery learned that Fermi and a dead Russian spy satellite, Cosmos 1805, were speeding toward the same point in space on nearly perpendicular orbits. They would miss being in that same place at the same time by only 30 milliseconds, likely passing within about 700 feet of each other.… Read more

Google, Nike, Jawbone and the fight to win wearable computing

When wireless headset company Jawbone announced plans Tuesday to buy wearable sensor maker BodyMedia for what a source said was more than $100 million, it may well have marked a turning point for wearable computing.

The technology, which includes everything from Google Glass eyewear to heart-rate monitors to sensors that slip into running shoes, has come of age. It's moving past the niche gizmos that only appeal to geeks and gearheads.

As a real business materializes around the technology, a battle is brewing among companies that want to put themselves at the heart of it, and profit from its … Read more

DARPA robot hand picks up keys, 50-pound weights

Mimicking the human grasp is no easy feat. Robotic hands tend to be clunky and expensive.

But now, the Defense Advanced Research Projects Agency is showing off a robotic hand that's dexterous enough to pick up keys and tough enough to survive being hit with a baseball bat.

The video below shows a prototype from DARPA's Autonomous Robotic Manipulation project. Instead of trying to reproduce the human hand in robot form, the prototype focuses on function. It has three fingers that are able to pick up small objects such as keys and credit cards, and it can even grasp objects with tweezers. … Read more

Robots in development can reach out and touch someone

Robotic prostheses may have a way to go before they work exactly like human limbs, but researchers are making great strides. A team out of Georgia Tech is working on new technology that could give these robotic limbs something akin to a sense of touch.

Thanks to tactile-sensing material that covers the entire prosthesis and software that integrates the gathered data, this robotic arm can maneuver through clutter and distinguish between hard and soft objects as it grips, pushes, and pulls more intuitively.

"Up until now, the dominant strategies for robot manipulation have discouraged contact between the robot's … Read more

Filmmaking at the atomic level? IBM nets Guinness world record

If you're looking to attract attention, setting a Guinness World Record is probably a good way to start.

That was the goal -- attracting attention, that is -- for a group of IBM Research scientists who recently set out to make what turned out be the Guinness World Record-certified smallest stop-motion film ever.

Called "A Boy and His Atom," the animated film features a small boy having a good old time as he bounces around, playing catch, and dancing. The twist? The film was shot at the atomic level and features 130 atoms that were painstakingly placed, atom by atom, as the researchers shot 250 individual frames. The images were created at a temperature of negative 268 degrees Celsius and were magnified 100 million times. … Read more

Gawk at new images of Saturn's super-sized hurricane

NASA released the most detailed images ever seen of a gigantic hurricane that scientists believe has existed at Saturn's north pole for years.

NASA's Cassini spacecraft snapped the spectacular pictures this past November from a vantage point approximately 261,000 miles from Saturn -- a distance so extreme that the above picture has an image scale of about 1 mile per pixel.… Read more

Canada launches robot-themed plastic banknote from space

By far the coolest thing Canada has in space is Chris Hadfield, commander of the International Space Station. He's all over social and news media with his wacky zero-g demos, guitar playing, and amazing photos of Earth.

Today Hadfield notched another first: unveiling a banknote in space. At a Bank of Canada press conference in Ottawa, the mustachioed colonel appeared via ISS video link. He plucked the bank's latest polymer bill from a bracket on the wall, gave it a few weightless twirls, and pointed to the robots it features.

"I just want to tell you how proud I am to be able to see Canada's achievements in space highlighted on our money," Hadfield told Bank of Canada Governor Mark Carney. "To feature Canadarm2 and Dextre for the theme of the $5 note, it really marks Canada's contribution to the International Space Station Program, and especially our longtime area of expertise in robotics." … Read more
