A 3-D View of the Brain

August 6, 2007

Researchers at Thomas Jefferson University Hospital have developed software that integrates data from multiple imaging technologies to create an interactive 3-D map of the brain.

The new imaging software collates data from different types of brain-imaging methods, including conventional magnetic resonance imaging (MRI), functional MRI (fMRI), and diffusion-tensor imaging (DTI). The MRI gives details on the anatomy, fMRI provides information on the activated areas of the brain, and DTI… read more

Web browser pioneer backs new way to surf Net

November 10, 2010

A new browser called RockMelt is built on the premise that most online activity today revolves around socializing on Facebook, searching on Google, tweeting on Twitter and monitoring a handful of favorite websites.

Rockmelt tries to minimize the need to roam from one website to the next by corralling all vital information and favorite services in panes and drop-down windows.

New Vehicles Will Make Own Decisions Based on Commands

November 19, 2004

The next war could be fought partly by unmanned aircraft that respond to spoken commands in plain English and then figure out on their own how to get the job done.

Truck-mounted laser shoots down spy drone

January 28, 2009

Boeing reports that their prototype truck-mounted laser has shot down a UAV at a missile range in New Mexico.

The Laser Avenger is an infrared laser with power levels somewhere in the tens of kilowatts range mounted on a Humvee off-road vehicle. It is designed to take down the smaller variety of UAV, which are hardest for conventional air-defence weapons to target. The power of its laser has been… read more

Disney Research creates 3D-printed interactive speakers of any shape

April 30, 2014

3d printed speaker

Scientists at Disney Research, Pittsburgh have developed methods to use a 3D printer to produce electrostatic loudspeakers that can take the shape of anything, from a rubber ducky to an abstract spiral.

The simple speakers require little assembly, but even those few manual steps might be eliminated in the future, said co-developer Yoshio Ishiguro, a Disney Research, Pittsburgh post-doctoral associate. “In five to 10 years, a 3D… read more

Behind BlueEyes

April 27, 2001

A number of large retailers have implemented surveillance systems that record and interpret customer eye movement and facial expression, using software from Almaden’s BlueEyes research project.

BlueEyes works by tracking pupil, eyebrow and mouth movement, using a camera and two infrared light sources placed inside the product display. One light source is aligned with the camera’s focus; the other is slightly off axis. When the eye looks into the… read more

His Heart Whirs Anew

August 14, 2007

The number of human bionic parts in existence or in the pipeline is accelerating, but now, in light of victims of psychological and cognitive trauma after intervention in their bodies, some scientists fear that we are tampering not with a bodily machine but with the human spirit.

Cyber detective links up crimes

December 6, 2004

Computer scientists at DePaul University have developed an artificial intelligence system for crime solving that compares records for cases with all the files on past crimes, looking for telltale similarities in crime records and alerting detectives when it finds them.

The system uses pattern-recognition software to link related crimes that may have taken place in widely separated areas whose police forces may rarely be in close contact. The neural… read more

Neurobiologist proposes ‘The end of sex as we once knew it’

February 3, 2009

Differences in the hormones of men and women make it likely that drugs and other treatments for some disorders should be tailored differently for the two sexes, says Rockefeller University’s Bruce S. McEwen.

The living dead

May 18, 2001

A cybernetic definition of “life” has been proposed by Bernard Korzeniewski of the Institute of Molecular Biology at Jagiellonian University in Kraków, Poland: “A network of inferior negative feedbacks subordinated to a superior positive feedback.”

In other words, life is a system that tries to regulate itself to preserve its identity. Uner this definition, ants, prions, and infertile humans are not alive, but parasitic DNA is, he says.

Coming Soon: Web Video in High Definition

August 21, 2007

Adobe has announced that it is integrating the standard H.264 format, the same video format used in Blu-Ray and HD-DVD video players and the latest cable and satellite set-top boxes for high definition video) into the newest version of its popular Flash video player.

Motion, Sensitive

November 29, 2010

The line between the real and the virtual in video games is beginning to fade.

Music games like Power Gig and Rock Band 3 are beginning to incorporate real musical instruments. Microsoft’s new Kinect system sees you and listens to you in your living room, letting you jump, swing, kick, or just sit on your couch and speak aloud to control what happens on your television. Meanwhile Internet games like Eve Online… read more

Test tube method analyzes and reconstitutes DNA-repair mechanism

December 15, 2004

One of five known DNA-repair mechanisms in cells has been completely analyzed and reconstituted in a test tube by an international collaboration of researchers led by scientists from the Keck School of Medicine.

The team is the first to reconstitute this pathway, known as the nonhomologous end joining pathway, or NHEJ, and NHEJ is only the third repair pathway to be reconstituted in the laboratory.

Professor works to revolutionize computer chips

February 9, 2009

Rice University professor Krishna Palem has created a microchip using “probabilistic computing” — using 30 times less electricity while running seven times faster than today’s technology.

The design accepts less-accurate results (adequate for graphics and music uses, for example) instead increasing voltage (and thus power) to compensate for increased noise at smaller dimensions.

New sensor could lead to low-cost medical imaging and night vision using smartphones and cameras

Low-cost medical and security cameras could be possible in the future thanks to a new multispectral light sensor developed by University of Surrey researchers. The sensor can detect the full spectrum of light, from ultraviolet (UV) to visible and near-infrared light.

“Until now … multiple sensors were required to measure different ranges of the light spectrum, significantly increasing cost,” said lead researcher Richard Curry, PhD. from the… read more
