Buoyancy Bazooka: Life-Saving Rocket-Propelled Grenade

Grenades are not exactly synonymous with life-saving, but they have inspired a young Sydney designer to create an award-winning device that could save swimmers from drowning.

Sam Adeloju’s design, named Longreach, with the unofficial name ”Buoyancy Bazooka”, shoots an emergency flotation device 150 metres out to sea. Made from hydrophobic foam, the buoy can expand up to 40 times its size on contact with water so the swimmer can stay afloat without risk the buoy will spring a leak. The device is also equipped with flares for night-time — via redwolf.newsvine.com

Internet Explorer browser share dips below 50%; Google Chrome rises

Microsoft’s Internet Explorer, which has dominated the Web browser market since blowing by Netscape in the late 1990s, last month fell below the 50% market share level for the first time in years.

IE’s share of the worldwide market fell to 49.87% in September, down from 51.3% in August and 58.4% a year ago. It is followed by Firefox, which increased its share slightly from 30.09% to 31.5% and Google Chrome, which grabbed 11.54% share, more than triple its September 2009 share, according to market watcher StatCounter — via redwolf.newsvine.com

Human waste turned into renewable gas to power homes

Next time you flush the toilet, you could be doing your bit for green energy. After being stored for 18 days, human waste will from today be returning to homes in the form of renewable gas.

Centrica is opening a plant at Didcot sewage works which will be the first in the UK to produce renewable gas for households to use.

National Grid believes that at least 15% of all gas consumed could be made from sewage slurry, old sandwiches and other food thrown away by supermarkets, as well as organic waste created by businesses such as breweries — via djd.newsvine.com

Google Street View Gets Grisly

Google sure does capture a ton of interesting stuff when it sends Street View cars around the world. Sometimes its 360-degree cameras pick up a disturbing image or two.

That allegedly is the case after Google announced this week it has added Antartica, Brazil, and Ireland to its Street View library. Shortly after its announcement, Brazilian site G1, allegedly found a corpse in Google’s online mapping service — via redwolf.newsvine.com

Iris Scanning Set To Secure City in Mexico, Then the World

The million-plus citizens of Leon, Mexico are set to become the first example of a city secured through the power of biometric identification. Iris and face scanning technologies from Global Rainmakers, Inc. will allow people to use their eyes to prove their identify, withdraw money from an ATM, get help at a hospital, and even ride the bus. GRI’s eye scanning systems aren’t more secure than others on the market, but they are faster. Large archway detectors using infrared imaging can pick out 50 people per minute, even as they hustle by at speeds up to 1.5 meters per second (3.3 mph). The first phase of the Leon iris and face scanning project has already begun. It is estimated to cost around $5 million and focuses on law enforcement agencies’ security check points. Over the next three years commercial uses will be rolled out with banks leading the charge. Check out the videos below to see GRI’s wide range of iris scanning stations in action. Whether you’re jealous or intimidated by Leon’s adoption of widespread eye identification you should pay attention to the project – similar biometric checkpoints are coming to locations near you. Some are already in place — via redwolf.newsvine.com

Light stimulation could restore movement to paralysed limbs

In a study that could eventually restore movement to humans’ paralyzed limbs, researchers at California’s Stanford University have used light to induce muscle contractions in mice. A gene derived from algae was inserted into the mice, encoding a light-sensitive protein which adhered to their nerve cell surfaces. Scientists then placed an optical cuff lined with tiny, inwards-facing LEDs around the mice’s sciatic nerves. By penetrating those nerves with brief, high-intensity bursts of blue light, they were able to produce muscle contractions similar to those that would occur naturally. The technology is called optogenetics — via redwolf.newsvine.com
