The Cyborg Leg It helps perfectly healthy runners run 30 percent more efficiently.
Tsukuba University


From Popular Science:

Attention cyborg wonks and lazy people: Japanese scientists at Tsukuba University have created a motorized knee that you can attach to your leg to increase your muscle power and running speed. The 11-pound kit's weight is shared by an exoskeleton-like attachment for your leg and a power source that's carried in a small backpack. But here's the best part: the device is not designed with any kind of rehabilitation or handicap-assisting function in mind; it's simply to make it easier for regular folks to run faster!

Computers Offer A Faster Way To Cure Humanity's Ills


From The Guardian:

Scientific research and medical breakthroughs increasingly depend on huge computer power.

HOW DO YOU predict whether a given patient is likely to die from a heart attack? Conventional medical wisdom would base a risk assessment on factors such as the person's age, whether they were smokers and/or diabetic plus the results of cardiac ultrasound and various blood tests. It may be that a better predictor is a computer program that analyses the patient's electrocardiogram looking for subtle features within the data provided by the instrument.

Rethinking Artificial Intelligence

From R&D:

The field of artificial-intelligence research (AI), founded more than 50 years ago, seems to many researchers to have spent much of that time wandering in the wilderness, swapping hugely ambitious goals for a relatively modest set of actual accomplishments. Now, some of the pioneers of the field, joined by later generations of thinkers, are gearing up for a massive “do-over” of the whole idea.

Davy Jones's Lock-Up


From The Economist:

Underwater robots can help study the world’s shipwrecks, a trove of information about the past, more easily and cheaply.

A SHIPWRECK is a catastrophe for those involved, but for historians and archaeologists of future generations it is an opportunity. Wrecks offer glimpses not only of the nautical technology of the past but also of its economy, trade, culture and, sometimes, its warfare. Until recently, though, most of the 3m ships estimated to be lying on the seabed have been out of reach. Underwater archaeology has mainly been the preserve of scuba divers. That has limited the endeavour to waters less than 50 metres deep, excluding 98% of the sea floor from inspection. Even allowing for the tendency of trading vessels to be coasters rather than ocean-going ships, that limits the number of wrecks available for discovery and examination.

New Underwater Explorers Go Where Scientists Can't



From Popular Mechanics:

Last week, an unmanned robot completed a 3300-mile trek across the Atlantic Ocean for the first time. The 134-pound robot, a glider named the Scarlet Knight, spent months at sea, gathering data on ocean temperature and salinity between the water's surface down to 600 feet below. The Scarlet Knight is just one of many new technologies scientists are turning to in order to research oceans, rivers and lakes—areas that are impractical, and in some cases impossible, for researchers to access themselves. By employing everything from robots to, yes, tadpoles, scientists hope to learn more about how climate change and pollution are affecting the earth's water. Here is some of the newest tech aiding scientists.

Learning To Love To Hate Robots

Low expectations are easily surpassed (Image: Steve Olson/Getty)

From New Scientist:

ROBOTIC helpers are not yet in every home. But in recent years robots have steadily marched into the real world to perform tasks such as cleaning floors, delivering drugs or simply entertaining.

That has let anthropologists and roboticists give these mechanical workers their first report cards - and results are mixed. Despite evidence that we can find robots useful, even lovable colleagues, they can also trigger annoyance and violence. The results should help make future robots easier to work with.

Science Goes Back To Basics On AI

From the BBC:

The Massachusetts Institute of Technology has begun a project to re-think artificial intelligence research.

The Mind Machine Project will return to the basics of AI research to re-examine what lies behind human intelligence.

Spanning five years and funded by a $5m (£3.1m) grant, it will bring together scientists who have had success in distinct fields of AI.

By uniting researchers, MIT hopes to produce robotic companions smart enough to aid those suffering from dementia.

From The Christian Science Monitor:

Engineers decode human balance to build walking robots.

For the past 30 years, scientists and technicians have grappled with making robots walk on two legs. Humans do it effortlessly, but the simple act has a lot of hidden complexity. And until recently, computers were very bad at it.

Now, several teams across the country are refining the first generation of robots that are close to walking like people. That includes the ability to recover from stumbles, resist shoves, and navigate rough terrain.

Five Ways To Revolutionise Computer Memory

Digital memory is getting smaller and smaller (Image: Chung Sung-Jun/Getty)

From New Scientist:

Once upon a time, not so long ago, the idea that you might store your entire music collection on a single hand-held device would have been greeted with disbelief. Ditto backing up all your essential computer files using a memory stick key ring, or storing thousands of high-resolution holiday snaps in one pocket-sized camera.

What a difference a decade makes. The impossible has become possible thanks to the lightning rise of a memory technology with the snazzy name of "flash".

MIT Plans To Rebuild Artificial Intelligence From The Ground Up

Artificial Intelligence: It's not what we think.

From Popular Science:

After 50 years and countless dead ends, incremental progress, and modest breakthroughs, artificial intelligence researchers are asking for a do-over. The $5 million Mind Machine Project (MMP), a patchwork team of two dozen academics, students and researchers, intends to go back to the discipline's beginnings, rebuilding the field from the ground up. With 20/20 hindsight, a few generations worth of experience, and better, faster technology, this time researchers in AI -- an ambiguous field to begin with -- plan to get things right.

Standing, from left, are Ralph Gorin, Whit Diffie, Dan Swinehart, Tony Hearn, Larry Tesler, Lynn Quam and Martin Frost. John Markoff

From The New York Times:

STANFORD, Calif. — The personal computer and the technologies that led to the Internet were largely invented in the 1960s and ’70s at three computer research laboratories next to the Stanford University campus.

One laboratory, Douglas Engelbart’s Augmentation Research Center, became known for the mouse; a second, Xerox’s Palo Alto Research Center, developed the Alto, the first modern personal computer. But the third, the Stanford Artificial Intelligence Laboratory, or SAIL, run by the computer scientist John McCarthy, gained less recognition.

From Christian Science Monitor:

Exoskeletons – or wearable robots – strengthen soldiers and mobilize the disabled.

The high-tech suits of “Iron Man” and “RoboCop” don’t seem so far off to Yoshiyuki Sankai. Since the third grade, this Japanese professor and inventor has been enchanted by Isaac Asimov’s story “I, Robot” and the idea that robots – or, in Mr. Sankai’s case, robotic suits – could help humans with everyday life.

In 2005, he unveiled several working prototypes of a mechanical, mind-controlled “exoskeleton” that could allow the disabled to walk. The suit – recently refined and now available for rent in Japan – resembles white soccer shinguards attached to each segment of the arms and legs and a fanny pack-like battery hooked around the waist.

From Live Science:

Robot clams may one day help dig up and detonate buried underwater mines, researchers now reveal. They could also serve as smart anchors for robot subs or deep-sea oil drilling.

Mechanical engineers Anette "Peko" Hosoi and Amos Winter at the Massachusetts Institute of Technology designed robots after the Atlantic razor clam (Ensis directus) because it is one of nature's best diggers. Using its relatively simple anatomy, the razor clam — which the researchers dubbed the Ferrari of underwater diggers — can burrow into the bottom of its native mudflats at a remarkable rate of roughly a centimeter per second.

Human Brains Emulated In The Computer World

From Alpha Galileo:

Researchers at LuleƄ University of Technology have created a computer-based architecture that mimics a pair of human brain functions. System that detects and compensates for their own shortcomings is a possible application, another is to reduce the impact of noise. The research takes a significant step forward because the research group has recently doubled.

We have developed a model of how the various sources of information that complement each other, can get a better idea of what is happening. Better to the extent that we may see more than what the different parts look, "says Tamas Jantvik researcher at LuleƄ University of Technology.
