Pluggd: A Google for Podcasts

December 21, 2006

Pluggd has found a way to index podcasts, talk shows and other spoken-word content. The company’s service then allows users to search the audio files for specific words, which are spoken in context by the original speaker.

How Plug-In Hybrids Will Save the Grid

December 21, 2006

A new concept, “vehicle-to-grid,” would allow plug-in hybrids to help stabilize the power grid.

Millions of cars, each with several kilowatt hours of storage capacity, would act as an enormous buffer, taking on charge when the system temporarily generates too much power, and giving it back when there are short peaks in demand.

Maintaining Moore’s Law without Silicon

December 20, 2006

At the International Electron Device meeting in San Francisco last week, MIT scientists presented research that revealed a possible silicon-free future for electronics. The team showed that a transistor made of a compound semiconductor called indium gallium arsenide could operate more than two times faster than a silicon transistor of the same size. The findings could keep Moore’s Law alive after silicon has reached its limit.

Nano-welds herald new era of electronics

December 20, 2006

Researchers have developed new welding techniques that can be used to assemble electronic components at smaller scales than have ever been possible.

One of them uses a 50-nanometer-wide carbon nanotube filled with copper inside a nanorobotic manipulator to connect objects in the same way that a human electrician might use solder.

New firm aims to be a Google for photos

December 20, 2006

Polar Rose, based in Sweden, has unveiled a new image search tool that uses 3D mapping techniques to recognize facial patterns.

Surgical Robots Get a Sense of Touch

December 20, 2006

Researchers at Johns Hopkins have developed a haptic feedback system for surgical robots, which lack subtle sensations.

Their goal is to understand the forces of the robot interacting with the patient and to use motors on the master robot–controlled by the surgeon–to create forces that are equal to those being applied to the patient.

Printing Muscle and Bone

December 19, 2006

Researchers at Carnegie Mellon University and the University of Pittsburgh have successfully directed adult stem cells from mice to develop into bone and muscle cells with the aid of a custom-designed ink-jet printer. They say it’s a first step toward better understanding tissue regeneration, which may one day lead to therapies for repairing damaged tissues, as occurs in osteoarthritis.

In Memory-Bank ‘Dialogue,’ the Brain Is Talking to Itself

December 19, 2006

New recordings of electrical activity in the brain may explain a major part of its function, including how it consolidates daily memories, why it needs to dream and how it constructs models of the world to guide behavior.

The finding by MIT researchers showed that during nondreaming sleep, the neurons of both the hippocampus and the neocortex replayed memories — in repeated simultaneous bursts of electrical activity — of… read more

Red light debut for exotic ‘metamaterial’

December 19, 2006

The race to build an exotic material with a negative refractive index for visible light has been won by a team of University of Karlsruhe researchers in Germany. The demonstration could open the door to a new generation of optical devices such as superlenses able to see details finer then the wavelength of visible light.

NASA Ames Schedules Briefing to Discuss Google Agreement

December 17, 2006

NASA Ames Research Center plans to announce a NASA/Google collaboration Monday to make NASA’s vast collection of data and imagery more easily available to the world.

Researchers Demonstrate Direct Brain Control Of Humanoid Robot

December 17, 2006

“Thought commands” generated by analysis of EEG signals can control the actions of robots, University of Washington researchers have found.

Tech lessons learned from the wisdom of crowds

December 17, 2006

Google, HP Labs, Yahoo, and Microsoft are among companies using “prediction markets” to improve forecasts.

The technique rewards employees for success in making predictions.

Computers ‘could store entire life by 2026′

December 15, 2006

A device the size of a sugar cube will be able to record and store high resolution video footage of every second of a human life within two decades, according to speakers at the Memories for Life conference at the British Library.

Nano-cables convert light into electricity

December 15, 2006

Nanocables that convert light into electricity could one day be used to power nanorobots, because of their similarity in size and function to the antennas used by bacteria for photosynthesis.

New surgical center is a big technological cut above the rest

December 15, 2006

The movie magic that allowed Gollum to lurch across the screen in the Lord of the Rings films or capture the great ape’s naturalistic movements in the remake of King Kong is now being used in operating room research and training in the new Maryland Simulation Training and Innovation Center at the University of Maryland Medical Center.

By recording how expert surgeons move during simulated surgeries, researchers hope to… read more
