CES 2012 to feature new TVs and interfaces

January 6, 2012

ces2010

Next week’s Consumer Electronics Show will focus on new television displays and interfaces, IEEE Spectrum Tech Talk reports.

Introductions will include a new glasses-free 3-D TV, big-screen (but expensive) OLED displays (deeper blacks and thinner than LCD displays), motion control and gesture recognition technology, eye and voice control, giant multitouch displays, and health and fitness monitoring devices.

A Terabyte In A Cigar Box

January 15, 2004

LaCie has introduced a 1 Terabyte disk for $1,199.

Mind over matter? How your body does your thinking

March 25, 2010

Recent research supports the “metaphor theory” — that we think of abstract concepts in terms of how our bodies function.

University of Melbourne researchers found that the direction of eye movements depends on whether numbers in a series heard by the subject are increasing or decreasing. And Max Planck Institute for Psycholinguistics researchers found that subjects moved marbles faster when retelling stories with positive emotional content than with stories… read more

Building ‘The Matrix’

July 30, 2008

Physicists at the Max Planck Institute for Quantum Optics have created a rudimentary prototype of a machine that simulates quantum phenomena using quantum physics, rather than using data kept in a classical computer.

It demonstrates a technique that could enable physicists to create, in the virtual world, materials that don’t yet exist in nature and perhaps figure out how to build, in the real world, superconductors that work at… read more

Report says most states still aren’t prepared for major emergencies

December 13, 2006

Five years after the Sept. 11 terror attacks, the country still isn’t fully prepared to respond to a major public health emergency such as bioterrorism or pandemic flu, a health policy group said in a report by The Trust for America’s Health.

For example, half of the states would run out of hospital beds within two weeks of a moderate outbreak — defined as eight to 12 weeks –… read more

Cooking nanomaterials in a microwave oven to make tomorrow’s solid-state air conditioners and refrigerators

January 11, 2012

cooking nanomaterials

Here’s how to make highly efficient refrigerators and cooling systems requiring no refrigerants and no moving parts: simply cook nanoscale thermoelectric materials with sulfur in a standard microwave oven, according to engineering researchers at Rensselaer Polytechnic Institute (RPI).

Thermoelectric refrigerators using solid-state cooling systems have been available for more than 20 years, but they are still small and highly inefficient because the materials are expensive… read more

Drug may give cells a fresh start

January 30, 2004

Scripps Research Institute chemists have found a synthetic molecule named “reversine” that seems to reprogram adult cells to make them more like youthful ones. It could provide an easy source of cells to regenerate tissues damaged by disease or injury, as an alternative to ethically controversial stem cells.

Look, no hands: Cars that drive better than you

April 6, 2010

We will see semi-autonomous vehicles on the highway by 2015, able to steer, accelerate and avoid collisions unaided, and fully autonomous vehicles by 2020, projects Alan Taub, vice-president for R&D at General Motors.

Meanwhile, Japan’s new Driving Safety Support System (DSSS), which can show alerts on satnav displays warning of traffic lights, stop signs and even pedestrians and cyclists on the road ahead, will be in use at major… read more

Invention: Exoskeleton for grannies

August 5, 2008

Yoshiyuki Sankai at the University of Tsukuba has developed an exoskeleton for a single arm that can improve the strength and utility of aging limbs.

The device consists of a tabard worn over the shoulders with a motorized exoskeleton for one arm attached. The exoskeleton senses the angle, torque and nerve impulses in the arm and then assists the user to move his or her shoulder and elbow joints… read more

Conscious computing debated at MIT anniversary event

December 22, 2006

Will there ever be such a thing as artificial intelligence? That question was argued by inventor Ray Kurzweil and Yale University professor David Gelernter.

Tiny scales weigh virus

February 11, 2004

Purdue University scientists have developed a scale that can weigh a 10 femtograms virus.

It uses a laser beam to measure the variation of wobble of a 30 nanometer-thick silicom springboard from the virus. Coating the springboard with antibodies will allow onlyone particular type of virus to stick to the scales. Such detectors could one day be used to monitor air purity in hospital or to assist in security… read more

Personalized medicine for cancer patients in a new technology era

April 15, 2010

Published online Wednesday in Nature, a paper authored by over 200 members of the International Cancer Genome Consortium (ICGC) describes a new era of personalized medicine for cancer patients.

“Given the tremendous potential for relatively low-cost genomic sequencing to reveal clinically useful information, we anticipate that in the not so distant future, partial or full cancer genomes will routinely be sequenced as part of the clinical evaluation of cancer… read more

Running ‘can slow aging process’

August 12, 2008

Stanford University Medical Center researchers have found that running on a regular basis can slow the effects of aging for elderly joggers.

The runners were half as likely to die prematurely from conditions like cancer than non-runners, and enjoyed a healthier life with fewer disabilities and delayed onset of disability.

The researchers tracked 500 older runners for more than 20 years, comparing them to a similar group of… read more

Time past, time future intricately connected in the brain: study

January 4, 2007

Researchers from Washington University have used advanced brain imaging techniques to show that remembering the past and envisioning the future may go hand-in-hand, with each process sparking strikingly similar patterns of activity within precisely the same broad network of brain regions.

“Results of this study offer a tentative answer to a longstanding question regarding the evolutionary usefulness of memory,” says Kathleen McDermott, an associate professor of psychology. “It may… read more

Biochemical clues to long lifespan revealed

February 20, 2004

Researchers at Children’s Hospital Boston have found that longer life results, at least in part, from biochemical interactions that boost cells’ ability to resist environmental stresses while inhibiting them from committing suicide.

The team found that the Sir2 gene regulates a group of proteins known as FOXO transcription factors. These proteins have been linked with longevity; they control the expression of genes that regulate cell suicide, and also enable… read more
