Engineers Make Like a Tree

July 10, 2006

Researchers are studying plant bionics, cherry-picking evolution’s best biological solutions and applying them to engineering problems.

Are you reading the news?

July 10, 2006

If you think you’re reading the news, be warned that this story — and any other on the web — will be barely read by anyone 36 hours after it was first posted. That’s the message from a team of statistical physicists who have analysed how people access information online.

Researchers at University of Notre Dame and in Hungary have calculated that the number of people who read news… read more

Google service to aid doctors, report says

July 10, 2006

Google is planning a service that will provide doctors, patients and health care providers with a way to manage medical information over the Web. Consumers will be able to log in and do things like check their medical records, add providers and pay bills.

Researchers create a broadband light amplifier on a chip

July 10, 2006

Cornell researchers have created a broadband light amplifier on a silicon chip, a major breakthrough in the quest to create photonic microchips.

The amplifier uses a phenomenon known as four-wave mixing, in which a signal to be amplified is “pumped” by another light source inside a very narrow waveguide. The waveguide is a channel only 300 x 550 nanometers (nm = a billionth of a meter, about the length… read more

How a Computer Knows What Many Managers Don’t

July 9, 2006

Many mutual funds that make their trades based on the recommendations of a proprietary computer model, known as quantitative or quant funds, have outperformed their benchmarks in the last three years.

Flat ‘ion trap’ holds quantum computing promise

July 9, 2006

Quantum computers could be more easily mass produced thanks to the development of a two-dimensional ion trap.

Ion traps work by trapping super-cooled ions in an electric field. Lasers can then be used to manipulate the ions to alter their quantum states.

Researchers at the National Institute of Standards and Technology (NIST) have developed a new way to make ion traps that can be easily scaled… read more

Seeking answers from the cosmic consciousness

July 9, 2006

Stephen Hawking has turned to Yahoo Answers for public answers to the question: “In a world that is in chaos politically, socially and environmentally, how can the human race sustain another 100 years?”

By afternoon July 7, nearly 17,000 Yahoo users had responded.

DVD uses bug protein to store data

July 9, 2006

DVDs coated with a layer of protein made from genetically altered microbe proteins, could allow DVDs and other external devices to store 50 terabytes of data.

High-tech prosthetics: Out on a limb

July 8, 2006

Icelandic prosthetic maker Ossur’s Rheo Knee, billed as the first knee with artificial intelligence, combines up to 15 sensors, a processor, software and a memory chip to analyze the motion of the prosthetic and learn how to move accordingly.

Bionics industry researchers estimate the next five years will bring major advances, including mind-controlled prosthetics in which sensors are attached directly to a patient’s brain. Already, companies and universities are… read more

Look into my mind

July 8, 2006

University College London researchers are using new optical tomography systems that can generate a 3-D map of individual blood vessels in the brain and tell from the color how oxygenated the blood is.

They are also safe enough to be used continuously, unlike other imaging methods.

Tweaking Genes in the Basement

July 7, 2006

The Biotech Hobbyist collective, an amateur biotech community, explores homebrew biotech.

Projects include basic computation using a DNA “computer.” Tools for the project include a $100 high school-science education kit and some used lab equipment.

Catching Seizures Before They Occur

July 7, 2006

Researchers at MIT and Harvard are preparing to carry out trials of a new device for treating epilepsy.

It involves implanting a pacemaker-like device in the patient’s chest. Connected to the device is an electrode that wraps around the vagus nerve. It uses powerful electrical stimulations and can be activated by the patient when a seizure occurs to try to stop it.

‘Smart’ spacecraft makes its own decisions

July 7, 2006

AI will increasingly give spacecraft the ability to think for themselves.

The AI group at NASA’s Jet Propulsion Laboratory wrote the software that manages the schedule of Earth Observing-1, a satellite that looks for natural disasters like volcanic eruptions, wildfires and floods. It reprograms itself to image these targets and provide rapid response imagery of breaking science events.

Similar programming can be used for future planetary missions, perhaps… read more

Make way for the terabyte laptop drive

July 7, 2006

Seagate Technology Inc. plans to increase disk capacity by 10 times with new technology it has just patented, meaning a computer hard drive could soon be storing as much as a terabyte of data.

The Heat-Assisted Magnetic Recording (HAMR) technology created by Seagate includes nanotube-based lubrication to allow the read/write head of a disk to get closer to the surface and store more information.

Self-Powered Silicon Laser Chips

July 6, 2006

A new method of turning waste heat into electrical power could speed up communications inside computers — and mark another advance in the field of silicon photonics.
