Submission + - 3D Bio-Printer To Create Arteries And Organs (gizmag.com)

Submitted by ElectricSteve on Wednesday December 16, 2009 @05:55PM

ElectricSteve writes: An engineering firm has developed a 3D bio-printer that could one day be used to create organs on demand for organ replacement surgery. The device is already capable of growing arteries and its creators say that arteries "printed" by the device could be used in heart bypass surgery in as little as five years. Meanwhile, more complex organs such as hearts, and teeth and bone should be possible within ten years.

Submission + - Researchers Build Working Single-Atom Transistor (gizmag.com)

Submitted by ElectricSteve on Sunday December 06, 2009 @11:35PM

ElectricSteve writes: An international group of researchers from the Helsinki University of Technology, the University of New South Wales and the University of Melbourne have successfully built a fully working transistor that is just one atom in size, smashing previous records and, more importantly, creating a very unique venue to study phenomena to be exploited in the rapidly developing field of quantum computing.

Submission + - Nano-Material Could Lead To Self-Cleaning Windows (gizmag.com) 2

Submitted by ElectricSteve on Friday December 04, 2009 @12:08AM

ElectricSteve writes: While searching for a cure to Alzheimer's, researchers at Tel Aviv University have discovered a new nanomaterial that can repel dust and water, and could provide a self-cleaning coating for windows or solar panels. The new material is made up of molecules of peptides that “grow” to resemble small forests of grass. The coating also acts as a super-capacitor, thereby having implications for electric cars in that it could provide an energy boost to batteries.

eldavojohn writes: Congressman Peter King (Republican — New York) is calling for a probe into Wikileaks with regards to the half million 9/11 pager messages published recently. He has announced plans involving his Washington staff conducting a preliminary investigation under the premise that this action 'raises security issues.' A word of caution, Congressman King has been known to make inflammatory and unpopular statements.

Submission + - World's Largest Hydro-electric Wave Energy Device (gizmag.com)

Submitted by ElectricSteve on Sunday November 29, 2009 @08:15PM

ElectricSteve writes: The world’s largest working hydro-electric wave energy device has been officially launched in Scotland. Known as Oyster, the device, stationed at the European Marine Energy Center (EMEC) Billia Croo site near Stromness, was installed this year and is, at present, the world’s only hydro-electric wave energy device which is producing power.

Submission + - The World's First Osmotic Power Plant (gizmag.com)

Submitted by ElectricSteve on Thursday November 26, 2009 @08:02PM

ElectricSteve writes: Her Royal Highness Crown Princess Mette-Marit of Norway officially opened the world's first osmotic power plant prototype on November 24. The prototype has a limited production capacity and will be used primarily for testing and data validation, leading to the construction of a commercial power plant in a few years time. Statkraft claims that the technology has the global potential to generate clean, renewable energy equivalent to China's total electricity consumption in 2002 or half of the EU's total power production

Submission + - Diamonds Deliver Speed Boost To Quantum Computers (gizmag.com)

Submitted by ElectricSteve on Tuesday November 24, 2009 @11:32PM

ElectricSteve writes: Scientists at UC Santa Barbara have made important advances in the field of spintronics by demonstrating the ability to electrically manipulate, at room temperatures, the quantum states of electrons trapped in the atomic structural defects of diamond crystals. Despite previous indications to the contrary, such quantum states can be manipulated very quickly, even at gigahertz frequencies, paving the way to significantly faster quantum computing.

Submission + - Vocal dinosaur bypassed in state R18+ game law 2

Submitted by Anonymous Coward on Tuesday November 24, 2009 @10:23PM

An anonymous reader writes: Many of you /.ers have had a nice chuckle about us Aussies lacking an R18+ game rating in Australia. Most of you have heard that just about the only person preventing a change to this is the South Australian Attorney General Michael Atkinson. Well in an interesting turn of events the Queensland government is looking to bring an R18+ game rating to the progressive state, thereby bypassing the national law. A Queensland Parliament E-Petition has been tabled (you know, the kind that government actually listen to) that should give them an idea of how popular this issue actually is and whether or not they should go against the vocal dinosaur Michael Atkinson.

From the petition:
"Queensland residents draws to the attention of the House that the Classification of Computer Games and Images Act 1995 is currently out of step with the wishes of the electorate.

Your petitioners, therefore, request the House that it be amended to permit computer games to receive the R18+ classification when they have been refused classification under the Commonwealth Act."

The petition can be found here (Queensland signatories only)

Submission + - Light resonators used to move nano-sized objects (gizmag.com)

Submitted by ElectricSteve on Friday November 20, 2009 @09:28AM

ElectricSteve writes: Scientists at Cornell University report they can now use a light beam carrying a single milliwatt of power to move objects and even change the optical properties of silicon from opaque to transparent at the nanometric scale.

Submission + - First Two-Qubit Programmable Quantum Computer (gizmag.com)

Submitted by ElectricSteve on Wednesday November 18, 2009 @09:42PM

ElectricSteve writes: In a paper recently published on Nature Physics, the National Institute of Standards and Technology (NIST) documented the implementation and verification of a two-qubit quantum computer that, according to researchers, is a truly general-purpose machine and could soon be used as a building block for much larger quantum computers.

Submitted by ElectricSteve on Monday November 16, 2009 @08:45PM

ElectricSteve writes: If you thought the status updates you already see on social networks weren't quite inane enough, prepare for the next level — automatically generated status updates. European researchers are working on a project called Awareness Services and Systems Towards Theory and Realization (ASTRA), and exploring the concept they call "pervasive awareness".

Submission + - Mavizen TTX02 electric superbike runs Linux (gizmag.com)

ElectricSteve writes: Gizmag brings news and exclusive images of the Mavizen TTX02 electric superbike, which was built for the world's first electric Grand Prix. The 130+ mph, GBP25,000 TTX02 is a "laptop on wheels" that runs on the Linux OS, comes with with integrated IP connectivity and a USB-based system bus for open-source engine management. It's not being sold as a street legal machine, but TTXGP founder Azhar Hussain says the package can still provide a pathway from the racetrack to the road.

Submission + - Next-generation TMOS displays closer to production (gizmag.com)

Submitted by ElectricSteve on Wednesday October 21, 2009 @09:14PM

ElectricSteve writes: Uni-Pixel is about to start mass production of a thin-film to be used in time-multiplexed optical shutter (TMOS) displays, a next-generation display technology that exploits retinal persistence in the human eye. Not only do TMOS displays promise significantly better performance than CRT, LCD and OLED displays, they're cheaper to manufacture, and offer great durability and dramatically improved energy efficiency.

Submission + - Magnetic nanotags for early cancer detection (gizmag.com)

Submitted by ElectricSteve on Tuesday October 20, 2009 @09:05PM

ElectricSteve writes: Extremely sensitive nanosensor chips are being developed by Stanford University researchers in an attempt to detect the early signs of cancer, called biomarkers, in humans. The researchers say their sensor is around 1,000 times more sensitive than current technology and is accurate regardless of which bodily fluid is being analyzed. It can also detect biomarker proteins over a range of concentrations three times broader than any existing method.
