Soon, vehicles that drive on their own

Washington, May 27 (ANI): Ever imagined reading a book or watching a movie in your car, while your vehicle guides itself through the traffic and navigates on its own? Well, thanks to a new technology called ‘autonomous vehicle navigation’, this could soon be a reality.

If this technology comes into action, it may also see fleets of self-navigating vehicles for the military operating in war zones.

Keeping this in mind, a Defense Advanced Research Projects Agency (DARPA) contest was conducted, which aimed at spurring the development of such technologies.

The DARPA Urban Challenge was held at a former air force base in Victorville, Calif. in late 2007, and offered a 3.5 million dollars purse to competitors who could design the fastest and safest vehicles that could traverse a 60-mile urban course in moving traffic in less than six hours.

The contestant vehicles were unmanned and had to complete a simulated military supply mission, manoeuvring through a mock city environment, avoiding obstacles, merging into moving traffic, navigating traffic circles, and negotiating intersections-all while conforming to California driving rules.

And out of the 89 international teams participating in the contest, only six could make it to the finish line in the allotted time.

The winning vehicle, which finished with the fastest time- an average speed of approximately 13 miles per hour- had Wende Zhang of General Motors as part of its design team.

The GM team incorporated existing technology already offered in some of their vehicles that can assist in parking or detect lane markers and trigger alarms if the drivers are coming too close to the shoulder of the road.

And for the DARPA challenge, they developed a more sophisticated package of sensors that included GPS coupled with a camera and a laser-ranging LIDAR system to guide and correct the vehicle’s route through the city.

In Baltimore, Zhang will present GM’s patented new methods for detecting lanes and correcting a vehicle’s route, which helped them win the challenge.

However, Zhang said that a commercially viable autonomous driving product might still take a decade to hit the markets.

The findings were presented at the 2009 Conference on Lasers and Electro-Optics/International Quantum Electronics Conference (CLEO/IQEC) at the Baltimore Convention Center in Baltimore. (ANI)

Star Trek-like scanners may soon be healing wounds with light

Washington, May 27 (ANI): If you thought that Star Trek scanners that fix injuries with beams of light was just a piece of fiction, just be ready for this-scientists have developed a new optical technology that could lead to better artificial tissues and wounds that heal faster with less scarring.

The new technology lines up living cells and controls their movements to effectively heal the wounds faster.

Scientists have long used the energy in laser light to drill microscopic holes or as tweezers or traps to direct and manoeuvre small pieces of matter.

However, guiding entire cells has proven difficult because the lasers used for manipulation tend to damage the structural units of living organisms.

But now, Aristide Dogariu and colleagues at the University of Central Florida in Orlando have developed an optical procedure that does not harm cells, but affects their skeletons – an ensemble of slender rods made out of an abundant protein called actin.

The actin rods are constantly growing and shrinking inside of cells, but the direction in which they grow changes the cell’s membrane shape and dictates where the cell moves.

The researchers used the polarization of optical waves to create a field around the cells in which the growing actin rods line up like a compass in the Earth’s magnetic field.

It is possible to use the optical fields to direct large groups of cells to line up and move in the same direction.

The technique could be useful for cancer assays, which test the motility of cells, or as a non-invasive, non-toxic boost for regenerative medicine.

The findings were presented at the 2009 Conference on Lasers and Electro-Optics/International Quantum Electronics Conference (CLEO/IQEC) at the Baltimore Convention Center in Baltimore. (ANI)

Little Boots tops BBC”s ‘Sound of 2009’ list

Washington, Jan 9 (ANI): BBC has named Little Boots, real name Victoria Hesketh, as the most promising Sound of 2009.

BBC”s Sound of 2009 list picks the musicians who show promise to hit the big time in the next 12 months.

The 24-year-old electro singer started her synth-pop sound soon after she branched out of disco outfit Dead Disco.

And the Blackpool singer has beaten White Lies, who stood at the second spot in the list.

“It is amazing that so many people want to write about me and give me opportunities, and I”m so grateful for that,” Contactmusic quoted Hesketh as saying of finishing in first in the Sound 2009 list.

She added: “For enough of those pundits to pick me as their favourite act is absolutely incredible and really mindblowing. I”m just so happy that it connects to those people. I hope it goes beyond that and translates and it isn”t just some bubble.

“I really hope that for every one of those amazing people who writes about you or plays you on their radio show, that will reach 1,000 people. Because that is what is going to make me be able to keep doing what I love.”

At the third position in the list was Florence and the Machine.

Rounding off at fourth and fifth position are Empire of the Sun and La Roux respectively.

The top ten in the BBC”s Sound of 2009 list are:

1 Little Boots

2 White Lies

3 Florence and the Machine

4 Empire of the Sun

5 La Roux

6 Lady GaGa

7 V V Brown

8 Kid Cudi

9 Passion Pit

10 Dan Black
