Omni-focus video camera developed

May 5, 2010

22145_web

University of Toronto researchers have developed a new kind of camera based on a new distance-mapping principle, that delivers automatic real-time focus of both near and far field images simultaneously (infinite depth of field), in high resolution, without physical movement of the camera’s optics.

The “Omni-focus Video Camera” contains an array of color video cameras, each focused at a different distance. It maps distance information for every pixel in… read more

Nano-sized ‘trojan horse’ to aid nutrition

August 26, 2008

Researchers from Monash University have designed a sponge-like chitosan biopolymeric nanoparticle “trojan horse” particle that protects antioxidants from being destroyed in the gut, ensuring a better chance of being absorbed in the digestive tract.

The longer-term aim is to include similarly treated nanoparticles into food items.

Moore’s Law Seen Extended In Chip Breakthrough

January 29, 2007

Intel Corp. and IBM have announced one of the biggest advances in transistors in four decades, based on a layer of hafnium.

The latest breakthrough means Intel, IBM and others can proceed with technology roadmaps that call for the next generation of chips to be made with circuitry as small as 45 nanometers. Researchers are optimistic the new technology can be used at least through two more technology generations… read more

RFID chips watch Grandma brush teeth

March 18, 2004

Intel researchers have demonstrated that data harvested from embedded wireless RFID chips could reassure family and care-givers that an elderly person was taking care of themselves, for example, taking their medication. Unusual data patterns would provide an early warning that something was wrong.

Walgreen To Sell Pathway Genomics Genetic Test Kits Mid-May

May 12, 2010

Walgreen Co. will sell genetic tests in about 6,000 of its stores starting in mid-May to help evaluate a person’s relative risk of developing certain diseases.

Walgreen plans to offer Pathway’s Insight Saliva Collection Kit at retail from $20 to $30. The saliva test, which will be done at Pathway’s labs, will cost between $79 and $249. Genetic tests typically cost about $300.

Introducing the Twiller

Some writers have begun using Twitter to write real-time stories, 140 characters at a time.

Winning ways

February 7, 2007

Supercomputer programs like IBM’s Deep Blue have demonstrated their ability to outthink human chess players. There is one game, however, where humans still reign supreme: Go. Yet here too their grip is beginning to loosen.

MoGo, a program developed by researchers from the University of Paris, has even beaten a couple of strong human players, using the Monte Carlo method, a form of statistical sampling. It is ranked 2,323rd… read more

Now NASA looks to change Mars into a garden of Earthly delights

March 29, 2004

Some scientists hope to terraform Mars, turning it into a blue world with streams, green fields and fresh breezes and ultimately providing mankind with a new home.

But first, they would need to thicken its atmosphere and heat up the planet so ice trapped in the Martian soil would melt and be used to sustain agriculture. One proposal: place a large mirror many miles in diameter in orbit above… read more

Google Pitches a Web-Centric Future

May 20, 2010

Google’s vision of the future is starkly different from those laid out by its rivals Apple and Microsoft, and calls for rich multimedia applications that operate within the browser — without the separate applications that people now download to their PC desktops or mobile phones.

For example, the forthcoming MugTug, a full-featured photo editing tool that operates within the browser, no software download necessary.

U.S. Edges Western Europe In 3G Adoption

September 5, 2008

Driven by popular handsets, the number of American mobile subscribers with 3G is 28.4%, versus 28.3% in the largest countries in Europe, and the number of U.S. subscribers with 3G-enabled devices has grown 80% to 64.2 million during the past year, comScore said.

Brain creates ‘new’ nerve cells

February 15, 2007

Researchers have discovered a type of brain stem cell that continuously regenerates in humans.

“Resting cells” migrate to create new nerve cells in the part of the brain that deals with smell.

Experts said the findings could be important for future research into brain cell repair in patients with neurodegenerative diseases such as Alzheimer’s disease.

With Tiny Brain Implants, Just Thinking May Make It So

April 13, 2004

Cyberkinetics Inc. plans to implant a tiny chip in the brains of five paralyzed people in an effort to enable them to operate a computer by thought alone.

The chip uses 100 electrodes connected by wires to an electronic device to analyze neural signals and send them to a computer. A future version will use a wireless connection.

Bill Joy on Sun’s downfall, Microsoft’s prospects, green tech

May 27, 2010

“The proper response to concerns [about nanotechnology] I raised would be sensible regulation, which doesn’t seem to be on the agenda right now. Let’s see if they can do proper regulation and inspection of offshore drilling. There’s an example where people didn’t have a reasonable plan if something bad happened.”

“That is a major disaster, but it’s not contagious. Imagine if one oil well leaked and because of that… read more

Deep brain stimulation offers hope to people with treatment-resistant illnesses

September 12, 2008

Deep brain stimulation, which uses electrical stimulation to jolt the brain in pinpointed locations, is use for treating a number of neurological and behavioral conditions, including Parkinson’s disease, epilepsy, severe depression, chronic pain, obsessive compulsive disorder, traumatic brain injuries, and Alzheimer’s disease.

Guiding researchers’ efforts are new brain maps generated by sophisticated imaging technologies such as functional MRIs and PET scans. By recording activity in both sick and healthy… read more

Rocket explosion creates dangerous space junk

February 26, 2007

A Russian rocket body exploded accidentally on Feb. 19, littering the skies with more than 1000 additional pieces of space junk.

The elliptical orbit could prolong the time the debris stays in space and the debris could cross the orbits of many existing satellites.
