Now, a 3D printer to serve you food

London: Technology has made our world easier in more than one way. With the convergence of technology these days, you can expect one gadget to do several jobs, away from what it is actually meant to do. A case in point here would be a printer that will serve you food. Don't believe it? Read on.The scientists at Cornell University, New York are in the process of developing a 3D food printer that will have ink in the form of raw food. How it will work is the raw food ink is fed into the printer and then you need to load the recipe of the desired food item and just click a button. And there you have your food readyAn electronic blueprint guides you as to where will each material be placed. It is created by using computer aided design (CAD) software.
The Daily Mail quoted Dr. Jeffrey Ian Lipton on the working of the printer, "FabApps would allow you to tweak your food's taste, texture and other properties. Maybe you really love biscuits, but want them extra flaky.…

eBooks help popularise literary classics

London: Literary classics by Charles Dickens and Jane Austen are enjoying a revival, thanks to eBook gadgets like the Amazon's Kindle.Kindles were the biggest selling products this Christmas, Amazon affirmed, as Britain finally embraced the eBook revolution.
Owners of eBook gadgets like the Kindle and the Apple iPad can snap up the works of many dead literary greats without paying a penny because they are out of copyright, reports the Telegraph.Coupled with the proliferation of these devices, titles such as "Pride and Prejudice" and "Treasure Island" have shot to the top of the eBook charts.The most popular e-Books over the Christmas period were Sir Arthur Conan Doyle's "The Adventures of Sherlock Holmes", Charles Dickens's "A Christmas Carol" and Bram Stoker's "Dracula".Even Homer's "The Iliad" made it into Amazon's top 20 of free Kindle eBooks last week. Amazon revealed that its 109 pounds Kin…

Microsoft Windows 7 Phone passes 1.5 million mark

More than 1.5 million Windows Phone 7 devices have been sold in the six weeks since the smartphone went on the market, Microsoft announced Monday.While far from the 300,000 daily activations attributed to the iPhone and phones powered by Google’s Android operating system, the Windows Phone sales figures met the company’s “realistic expectations”, Microsoft executive Achim Berg said in a web posting.The phone is seen as Microsoft’s attempt to get its foot in the door of the smartphone market after years in which the technology giant was eclipsed by Google, Apple and RIM’s Blackberry.
Devices running Windows Phone 7 software are currently made by HTC, Dell, Samsung and LG and have been well reviewed by analysts.“We all know that the competition is extreme in this industry, and we have to compete on multiple fronts,” said Berg, vice president of business and marketing for Windows Phones.“We are on a path to begin releasing the first of several updates in the next couple of m…

Smartphones too smart for owners

London: With hundreds of thousands of applications available, smartphones allow users to do anything from checking their bank balance to booking a flight. But 71 percent of owners use them simply to make a call, text or log on to Facebook , a new study shows.The study by Envirofone, which recycles mobiles, revealed that a typical smartphone owner exploits only 10 percent of the phone's functions, reports the Daily Mail.The survey of 2,000 users also found more than half had felt pressured to get the latest or most popular smartphone such as Apple's iPhone4 or a BlackBerry .
The devices, among top gadgets in this year's New Year shopping list, are really pocket computers. In addition to the capacity for the downloadable programs, known as "apps," they can also browse the internet and send and receive emails.The research estimates there are 11 million smartphones in the UK.
While there are many useful "apps" offering train information or satelli…

IBM designed memory Racetrack takes another step toward reality

When Aparna (name unchanged), a lawyer, typed her name in Spokeo's search box, the results shocked her. The address where she had stayed in the United States — a piece of information she thought was not public — was there on the map for anyone to see.Spokeo (www.spokeo.com) says it is “not your grandma's phonebook.” It is true because the site does something your grandma's phonebook could never dream of — it mines the net collecting public information on a person, stitches the scattered bits of data together to weave a comprehensive snapshot of the person. You can obtain such a dossier on virtually anyone in the online world for as low as Rs.150 a month. Pipl, 123People, and Intelius are sites similar to Spokeo.“Informed consent,” is the key to sharing information online, says Balachander Krishnamurthy, a researcher with AT&T Labs Research, U.S., whose interests include Internet privacy and online social networks. Though the first step to informed consent i…

‘Wireless’ humans could backbone new mobile networks

People could form the backbone of powerful new mobile internet networks by carrying wearable sensors.The sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations.Engineers from Queen’s Institute of Electronics, Communications and Information Technology are working on a new project based on the rapidly developing science of body-centric communications.Social benefits could include vast improvements in mobile gaming and remote healthcare, along with new precision monitoring of athletes and real-time tactical training in team sports, an institute release said.The researchers are investigating how small sensors carried by members of the public, in items such as next generation smartphones, could communicate with each other to create potentially vast body-to-body networks.The new sensors would interact to transmit data, providing ‘anytime, anywhere’ mobile network connectivity.Simon Cotton from the insti…

New software helps edit billions of pixels in seconds

Washington: Computer scientists have developed a software that quickly edits "extreme resolution imagery," huge photographs containing billions to hundreds of billions of pixels or dot-like picture elements.Until now, it took hours to process these "gigapixel" images. The new software needs only seconds to produce preview images useful to doctors, intelligence analysts, photographers, artists, engineers and others. By sampling only a fraction of the pixels in a massive image - for example, a satellite photo or a panorama made of hundreds of individual photos - the software can produce good approximations or previews of what the fully processed image would look like, reported computer graphics journal, ACM Transactions on Graphics.That allows someone to interactively edit and analyse massive images - pictures larger than a gigapixel (billion pixels) - in seconds rather than hours, said Valerio Pascucci, associate professor of computer science at the Un…

Facebook generation ‘loneliest among all age groups’

Britain’s “Facebook generation” — the 16 to 24-year-olds — are the loneliest among all age groups, a survey has revealed.In the survey, one in three said that they were bored with their lives compared to just eight per cent of pensioners and 28 per cent complained loneliness was making them unhappy and so they are taking to drinking.More than a quarter of the Facebook generation revealed they turned to alcohol for comfort, and half admitted to using junk food as an emotional crutch, found the poll conducted for ‘BBC Radio 3’Asked what made them unhappy, 70 per cent of the 16 to 24 year-olds said finances topped their list of concerns. More than a third were worried about holding down a job, compared to a quarter of middle-aged respondents.One in three said they were tormented by family or relationship problems, and they were also the age group that were most likely to struggle over their social status. But money was the biggest cause of unhappiness across all age groups, …

Google was in ‘significant breach’ of data law: U.K.

Google drew international outrage after it emerged that its Street View cars, which take street-level photographs to illustrate the company’s popular mapping service, had also been scooping up e-mails, Internet addresses and passwords from unencrypted wireless networks.Google violated Britain’s data protection laws when its Street View mapping service recorded data from private wireless networks, the country’s information commissioner said on Wednesday.The American Internet search giant will escape any fines, however, so long as it pledges not to do it again.Google Inc. drew international outrage after it emerged that its Street View cars, which take street-level photographs to illustrate the company’s popular mapping service, had also been scooping up e-mails, Internet addresses and passwords from unencrypted wireless networks.Scotland Yard recently said it would not launch a criminal inquiry into the breach, which the company has described as inadvertent.Information Com…

Ten years on the International Space Station

On Tuesday, the world celebrated the space station’s 10th birthday — the longest period of time of continuous human habitation outside Earth’s atmosphere.The three Russian and three U.S. astronauts who currently live aboard the International Space Station celebrated the occasion with a special meal and a congratulatory call from NASA Administrator Charles Bolden.Bolden spoke of the “toehold in space” provided by the orbiting station and the international cooperation used to create it.“As we enter the station’s second decade, our path forward will take us deeper into space and expand humanity’s potential farther,” he said. “The lessons we learn on the station will carry us to Mars and beyond. I want to give a heartfelt thank you to the six crew members on orbit and all the teams over the years that have helped us get to this milestone day.” It began on November 2, 2000, when an American and a Russian astronaut floated side by side into the ISS that orbits more than 300 ki…

Indians have highest smartphone security concerns

Indians have shown the highest level of user concern for mobile security issues at 90 percent among the 16 countries, included in a global consumer survey.Brazil and Russia (88 per cent each), Germany (86 per cent) and China and Italy (both at 85 per cent) were the other countries with high level of security concerns while respondents in Hong Kong (70 per cent), Belgium/Netherlands (74 per cent) and the U.S. and Japan (77 per cent each) were the least concerned by comparison.The global consumer study by Juniper Networks found that four out of five people cite “level of security” as a top or high priority when buying or using smartphones and tablet computers and more than half are anxious about losing their mobile devices, protecting their identities and protecting their families with parental controls.At the same time, nearly three out of four people surveyed use their mobile devices to share or access sensitive personal or business information.The research, commissioned…

Be sure to wipe memory devices before resale

Anyone who plans to resell a used computer memory device like a hard drive, memory card or a USB stick should be sure to use a special programme to wipe the storage device first.Not doing so risks having your personal data reconstructed by prying eyes, warns German computer magazine Computer Bild.In a test organized by the magazine, experts purchased used storage devices and managed to reconstruct private data like bills, emails, contact data, addresses, tax declarations and photos.That’s because, on Windows, when items are thrown into the wastebasket, they don’t really disappear from the device. Even formatting the hard drive does not get rid of the directory: the data can always be recovered with special programmes.Thus, people need to buy special programmes to completely erase their mobile storage devices before they sell them on. In the magazine’s test of eight cleanup programmes, the free HDShredder 3.8 was the champion.Nonetheless, wiping a drive takes time. All progra…

Smartphone war: Windows Phone 7 enters the market with a vengence

Better late than never. That was Microsoft’s unspoken mantra on Monday as its Windows Phone 7 went on sale in the US in a bid to challenge the dominance of arch-rivals Apple and Google in the smartphone market.The launch comes amid a pivotal period for Microsoft. The company has been coasting for years on the coattails of Office and Windows. But last week it launched its game-changing video-game controller Kinect that allows users to manipulate xBox games with their body movement, handing the company an important advantage in its battle with Nintendo and Sony.Windows Phone 7 has also been well received by reviewers, many of whom have been openly derisive of Microsoft’s past efforts in the smartphone space. But whether the Windows Phone will ever gain enough impetus to be the top dog in mobile, as the Windows operating system is in PCs, is doubtful, and that could spell trouble for the ageing software giant from Seattle.True, PCs are not going to disappear any time soon.

Fast-paced video games boost ability to concentrate

The authors referred to a number of training studies that found non-gamers could improve their visual attention by playing video games, according to the Daily Mail.However, only fast-paced, action-based games provided this benefit. These games emphasised rapid responses to visual information and required divided attention.Study co-author Bjorn Hubert-Wallander said: "Just as drivers have to focus on the road, other cars and potential obstacles while ignoring other information, modern action games place heavy attentional demands on players."These games require players to aim and shoot accurately in the centre of the screen while continuously tracking other enemies and fast-moving objects."The findings could have implications for military training as well as clinical rehabilitation programmes for conditions such as amblyopia or 'lazy eye'.

Nuclear-powered 'space hopper' to leap across Mars

London: Scientists have designed a Mars hopper that could explore the surface of the red planet by leaping half a mile at a time.It would be able to travel 400 miles during a six year mission, far more than what Nasa's intrepid Spirit Rover managed 15 miles over seven years.The innovative vehicle would move by sucking in carbon dioxide from Mars' atmosphere and compress it into fuel, before blasting it out in much the same way as a rocket, reports the journal Proceedings of the Royal Society A.It would take a week for the vehicle to recharge. During this time it would carry out tests on Mars' physical and chemical surface and sub-surface, reports the Daily Mail.Nigel Bannister from the University of Leicester said: "At the heart of the vehicle is a radio isotope heat source (one that relies on nuclear decay).""This heat source would be used in two ways. In one mode, the heat source would impart thermal energy into the propellant (fuel), which wo…
