Intel’s unveils world’s smallest transistor with 15-nm device

November 20, 2001

Intel has developed a 15-nanometer device that will be used to make microprocessors and other chips by the end of this decade. The new technology is said to handle switching speeds of 0.38 picoseconds, or or 2.63 trillion switches per second.

Bluetooth 3.0 Goes Live

April 23, 2009

The next-generation Bluetooth 3.0 will allow for a theoretical maximum throughput of 24 Mbps — enough to transmit HD videos.

Products are expected by yearend, but many current Bluetooth devices can be updated to Bluetooth 3.0 via driver, firmware, or software update.

Optical imaging method shows brain multiplexing

March 25, 2011

Brain-Image

Researchers have developed a real-time optical imaging method that exploits a specific voltage-sensitive dye to demonstrate brain multiplexing in the visual cortex, says Dr. Dirk Jancke, neuroscientist at the Ruhr-University in Bochum, Germany.

Neurons synchronize with different partners at different frequencies. Optical imaging allows fine grained resolution of cortical pattern activity maps in which local groups of active nerve cells represent grating orientation. A particular grating… read more

Human embryonic stem cells grown animal-free

March 18, 2005

Three teams have managed to derive and grow human embryonic stem cells without using any animal cells that might contaminate them.

All existing embryonic stem cells lines could be tainted with animal diseases or substances that would trigger transplant rejection.

This is your brain on violent media

December 7, 2007

Researchers at Columbia University Medical Center’s Functional Magnetic Resonance Imaging (fMRI) Research Center have shown that watching violent programs can cause parts of your brain that suppress aggressive behaviors to become less active.

Depictions of violent acts have become very common in the popular media,” said Christopher Kelly, the first author on the paper and a current CUMC medical student. “Our findings demonstrate for the first time that watching… read more

Apostle of Regenerative Medicine Foresees Longer Health and Life

December 19, 2001

Life in perpetuity will be secured by “rejuvenative medicine” — repairing the body by developing new tissues and organs as the old ones wear out — and nanotechnology, says Dr. William A. Haseltine, CEO of Human Genome Sciences.He sees rejuvenative medicine growing out of “regenerative medicine,” which will unfold in four phases.

1. The first phase is using the body’s own signaling factors to stimulate healing… read more

Deals to Develop Fuel Cell Vehicle

March 30, 2005

General Motors and DaimlerChrysler have signed agreements with the Department of Energy to develop hydrogen fuel cell vehicles over the next five years.

Toshiba Introduces New 10 Year, Quick Charge Industrial Battery

December 13, 2007

Toshiba has developed a battery that can be recharged in five minutes with a lifespan of 10 years.

Toshiba’s Super Charge ion Battery (SCiB) is designed to lose less than 10 percent of its efficiency after 3,000 recharges.

Fuel Cells That Fit in a Laptop

January 24, 2002

Smart Fuel Cell GmbH of Bavaria has developed a micro fuel cell that runs on methanol and provides much longer life than any other portable battery. It is the first to not require any standard batteries.
The fuel cell is aimed at power-hungry devices such as notebook computers, camcorders and specific applications for environmental and transportation markets.

A fuel cell is an electrochemical device that produces electric power from… read more

Ear Plugs to Lasers: The Science of Concentration

May 5, 2009

Now that neuroscientists have identified the brain’s synchronizing mechanism, they’ve started work on therapies to strengthen attention.

Ultimately, it may be possible to improve your attention by using pulses of light to directly synchronize your neurons, a form of direct therapy that could help people with schizophrenia and attention-deficit problems, said Dr. Desimone, the director of the McGovern Institute for Brain Research at MIT.

In the nearer future,… read more

Constructing buildings with 3D printers

April 8, 2011

Neri Oxman, an architect and a professor at MIT’s Media Lab, intends to print beams, bricks, concrete columns, and other construction materials using 3D printers to build structures layer-by-layer.

Oxman’s 3D printers change the elasticity of a polymer or the porosity of concrete as it’s printed, with print heads mounted on flexible robot arms that have greater freedom of movement than current printers.

She draws inspiration from nature to… read more

Look out for giant triangles in space

April 12, 2005

The search for extraterrestrial intelligence (SETI) should look for giant structures placed in orbit around nearby stars by alien civilizations, says Luc Arnold of the Observatory of Haute-Provence in France.

And he believes that the generation of space-based telescopes now being designed will be able to spot them.

To ensure the signal is unambiguous, an alien civilization would have to launch a number of objects into orbit around… read more

Watching the Watchers: Why Surveillance Is a Two-Way Street

December 18, 2007

The widespread availability of digital cameras and video-capable cellphones means that ubiquitous surveillance on the part of the little guys is moving, if anything, even faster than ubiquitous surveillance on the part of the big boys. And distribution tools like YouTube make it easier to get the footage to a large audience.

Developing New Operating Systems

February 13, 2002

Ongoing research and development in operating systems is extending the ability for individuals and groups to use worldwide computing resources.

  • The Legion Project: Researchers at the University of Virginia are developing Legion, a highly flexible, wide-area operating system designed to build a virtual computer from millions of distributed hosts and trillions of objects while presenting to the user the image of a single computer.
