Scientists have created an ultra-fast computer chip which is 20 times faster than current desktop computers.
Modern PCs have a processor with two, four or sometimes 16 cores to carry out tasks.
But the central processing unit (CPU) developed by the researchers effectively had 1,000 cores on a single chip.
The developments could usher in a new age of high-speed computing in the next few years for home users frustrated with slow-running systems.
And the new ‘super’ computer is much greener than modern machines – using far less power – despite its high speed.
Scientists used a chip called a Field Programmable Gate Array (FPGA) which like all microchips contains millions of transistors – the tiny on-off switches which are the foundation of any electronic circuit.
A solar-powered pilotless plane which was built in the UK has been recognised as having smashed the world record for the longest time spent in the air by an unmanned autonomous vehicle (UAV), after staying aloft for two weeks.
The record-breaking flight took place in July over the US and has now been ratified by the Federation Aeronautique Internationale (FAI), which governs air sports records. The 50kg craft remained airborne for 14 days, 22 minutes and 8 seconds – 11 times longer than the previous record.
Potential uses for the aircraft, which is built by defence technology company Qinetiq, include the long-distance tracking of hijacked ships and aerial monitoring of forest fires. Chris Kelleher, chief designer, said: “This aircraft can help track pirates off the Horn of Africa and also ensure that soldiers’ communications remain unaffected when fighting in mountainous or hilly terrain.”
Vantage point is everything when it comes to surveillance. SkyWatch™ units provide a high level platform for an array of surveillance options. Every tower includes the basics for the comfort and safety of the officer inside through adjustable heat and air conditioning, tinted sliding glass windows and comfortable seating. And no matter the application, only one person is required to set up and deploy a unit.
The SkyWatch can easily be relocated and is rugged enough to handle even the most primitive off-road conditions. And all models are adaptable for cameras, radios, public address systems and other equipment integration.
Now, one officer can cover an area previously requiring three or more personnel.
Scientists raise hopes for a large-scale renewable source of liquid fuel with a simple reactor that mimics plants
A simple reactor that mimics plants by turning sunlight into fuel has been demonstrated in the laboratory, boosting hopes for a large-scale renewable source of liquid fuel.
“We have a big energy problem and we have to think big,” said Prof Sossina Haile, at the California Institute of Technology, who led the research.
Haile estimates that a rooftop reactor could produce about three gallons of fuel a day. She thinks transport fuels would be the first application of the reactor, if it goes on to commercial use. But she said an equally important use for the renewable fuels would be to store solar energy so it is available at times of peak demand, and overnight. She says the first improvements that will be made to the existing reactor will be to improve the insulation to help stop heat loss, a simple move that she expects to treble the current efficiency.
The key component is made from the metal cerium, which is almost as abundant as copper, unlike other rare and expensive metals frequently used as catalysts, such as platinum. Therefore, said Haile, availability would not limit the use of the device. “There is nothing cost prohibitive in our set-up,” she said. “And there is plenty of cerium for this technology to make a major contribution to global gasoline supplies.”
Drawback? Most programmes for smartphones, such as this iPhone, send data back to companies that sold them
Dozens of popular iPhone apps are secretly monitoring users and sending information back to companies – who then use it to target them with adverts.
More than half of the programmes and games for smartphones sent data back to the private companies once they had been downloaded, a study found.
The apps include the wildly popular Angry Birds game and music identifying software Shazam, which comes pre-installed on every iPhone.
Armed with this information firms including Google track the individuals’ movements and sell personalised adverts for which they can make more money than regular ones.
The study found that of 101 apps tested, 56 transmitted the phone’s individual number to a private company in some way, known as the Unique Device Identifier or UDID.
Some 47 sent the phone’s location and five sent age, gender and other personal information.
More data was sent back about a user’s location on the Apple’s iPhone than Google’s Android smartphone, the research discovered, even though both companies have promised not to let such practices take place.
The research was carried out in the U.S. but it would apply to users downloading apps from anywhere in the world.
Patriot App has been criticised for encouraging neighbours to report each other
It claims to be a handy way to make you a ‘better citizen’.
But a new app for the iPhone has been condemned by critics who claim it is turning mobile users into a network of government spies.
The PatriotApp links your phone to American security and law enforcement agencies via the Internet and allows you to report anything you want at the touch of a button.
By simply pressing the relevant icon, users can sound the alarm for terrorism, ‘suspicious activity’, a health pandemic or an environmental safety issue.
The $0.99 app, named after the controversial Patriot Act brought in by the U.S. government after 9/11, is designed to ‘encourage active citizen participation in the War on Terror and in protecting their families and surrounding communities’, its makers Citizen Concepts claim.
But critics say it is like putting Big Brother in the palm of your hand and could easily be open to abuse by those with questionable agendas.
The app works by making a direct link between your phone and law enforcement agencies such as the FBI and the Environmental Protection Agency.
The software also links up to your Facebook and Twitter page meaning you can post alerts on there if needed.
Thousands of South Korean men too busy to date are finding solace in a new piece of technology – an iPhone application that offers lonely souls a virtual girlfriend.

The Honey It’s Me! application enables users to interact with the voice of a twenty-something virtual girlfriend called Mina.
The application allows singletons to receive four video calls from Mina a day as well as a shower of love messages from a selection of 100.
A Korean model posed for the video calls and recorded an array of “girlfriend” comments, which range from “Are you still sleeping? Time for breakfast!” to “Good night, sweet dreams”.
The application – devised by South Korean company Nabix – attracted 80,000 downloads a day during the initial free launch period and currently costs a daily fee of £1.26 ($1.99).
Explaining why he created the device, Kim Yoon-Kak, head of Nabix, said: “I’ve developed this application to console people for their loneliness.” The company is planning to tap into a global market of lonely hearts with new versions to be launched in English, Chinese and Japanese, with an Android version also in the pipelines.
Meanwhile, it appears that the reception of the virtual girlfriend technology in South Korea has been increasingly positive among the numerous men too busy with work to find a real life girlfriend.
One user stated on Twitter: “It’s a blessing for all single men.” Another added: “Mina called me while I was working overtime. This is just great.”
‘Rises in C02 lag 800 years behind temperature rises. So temperature is leading CO2 by 800 years!’
CO2 is environmentally friendly and global warming and the carbon hype are a scam. Even IF there would be global warming, then CO2 would have nothing to do with it, because CO2 lags 800 years behind rising temperatures! That is a a scientific fact and if you watch ‘An Inconvenient Truth (Lie)’ again, then you will see exactly that in Al Gore’s graph. (You know, that fake hockey stick graph.)
And yes, the hockey stick graph is fake and this is so obvious:
Electricity bills will have to rise by up to £500 a year to pay for a new generation of environmentally friendly power stations, it emerged.
Chris Huhne, the Energy Secretary, will outline government plans today to encourage energy companies to develop low-carbon power plants, including nuclear power stations and wind farms.
Energy analysts say the Coalition’s plans will put Britain on course for a “high cost, low carbon” electricity market where consumers pay the price for environmentally friendly generating technology.
Energy companies say that the shift will require them to invest more than £200 billion in new power stations and networks over the next 20 years.
According to uSwitch, the price comparison website, funding that investment will cost households more than £500 a year on top of the current total average energy bill of £1,157. Mr Huhne’s officials dispute that figure and insist that the direct costs of specific government policies will be much lower.
A new consultation will push energy companies into investing billions of pounds in technology, costs that companies say will be passed on to consumers.
A new tax could be levied on fossil fuels such as coal and gas, making them more expensive relative to low-carbon sources of energy such as nuclear and wind power.
The US Navy announced a successful test Friday of an electromagnetic cannon capable of firing a projectile 110 nautical miles (200 kilometers) at five times the speed of sound.
This demonstration moves us one day closer to getting this advanced capability to sea,” said Rear Admiral Nevin Carr, chief of naval research.
Tested at the Navy’s Dahlgren Surface Warfare Center in Virginia, the futuristic weapon uses powerful jolts of electric current to propel a non-explosive slug along rails before launching it at supersonic velocities.
The latest test involved a 33-megajoule shot, the most powerful ever attempted and three times that of the previous test in January 2008.
A megajoule is equivalent to the energy released when a one-tonne vehicle slams into a wall at 100 miles (160 kilometers) per hour.
“Today’s railgun test demonstrates the tactical relevance of this technology, which could one day complement traditional surface ship combat systems,” Carr said.
“The 33-megajoule shot means the Navy can fire projectiles at least 110 nautical miles, placing sailors and marines at a safe standoff distance and out of harm’s way.”
Babies who watch TV are more likely to have delayed cognitive development and language at 14 months, especially if they’re watching programs intended for adults and older children. We probably knew that 24 and Grey’s Anatomy don’t really qualify as educational content, but it’s surprising that TV-watching made a difference at such a tender age.
Babies who watched 60 minutes of TV daily had developmental scores one-third lower at 14 months than babies who weren’t watching that much TV. Though their developmental scores were still in the normal range, the discrepancy may be due to the fact that when kids and parents are watching TV, they’re missing out on talking, playing, and interactions that are essential to learning and development.
This new study, which appeared in the Archives of Pediatric and Adolescent Medicine, followed 259 lower-income families in New York, most of whom spoke Spanish as their primary language at home. Other studies examining higher-income families have also come to the same conclusion: TV watching not only isn’t educational, but it seems to stunt babies’ development.
