Google search accelerates with 'instant' results

Google is accelerating its search engine by displaying the results as soon as users begin to type in their requests.
The new “Instant Search’ introduced on Wednesday means people will start to see an ever-evolving set of results in the middle of the page with each character they type into the search box. The new feature will gradually roll out throughout the rest of the day.
Instant Search grew out of Google Inc.’s quest to deliver search results as quickly as possible. Google believes this feature will enable its search engine to anticipate what a person is looking for with just one keystroke.
Google is counting on the latest innovation to help maintain its dominance of the lucrative search market as rivals Yahoo Inc. and Microsoft Corp. join forces.

3D illusion of child gets drivers to brake

A school in Canada is using a weird 3D optical illusion of a young girl crossing the road to rein in rowdy drivers.
The image of a girl pursuing a ball is painted on the road and lengthened to make it seem three-dimensional, viewed from an approaching car.
Critics aver that the child's image could jolt the drivers into slamming on the brakes or swerve off the road if they don't realise the girl is just an illusion, reports the Daily Mail.
From afar it just looks like a marking but when the car is close to 30 metres, it appears to instantly rise up from the road.
When the driver is closer than 30 metres the image appears to sink back into the road. If a car is travelling at the speed limit for the road, 30 kmph, then he should be able to stop in time before he reaches the image.
Safety experts say the alarming image is designed to teach drivers to always be prepared for the unexpected.
The illusion is to be placed on the road outside the École Pauline Johnson Elementary School in West Vancouver in Canada and will be accompanied by a sign which reads: "You're probably not expecting kids to run into the road."
Area's council bosses say that the illusion will encourage drivers to drive defensively, as though a child could run out into the road at any moment. The image will be removed after a week.

Most Facebook users have low self-esteem: Study

Facebook is used mostly by narcissists and those with low self-esteem, says a Canadian study.
These type of people use Facebook as a self-promotional tool, says psychology researcher Soraya Mehdizadeh of York University.
Mehdizadeh, who extensively examined the online habits and personalities of 100 Facebook users aged 18 to 25 years old, found that individuals higher in narcissism and lower in self-esteem spent more time on the site and filled their pages with more self-promotional content.
"We all know people like this. They are updating their status every five minutes and the photos they post are very carefully construed," she says.
"The question is, are these really accurate representations of the individual or are they merely a projection of who the individual wants to be?"
Mehdizadeh says she was struck by the fact that those with lower self-esteem were more apt to use this social networking tool.
As part of her research, she examined five features of participants' Facebook pages for self-promotion: the 'about me' section, the main photo, the first 20 pictures on the 'view photos of me' section, notes, and status updates.
Describing self-promotion by Facebook users as any descriptive or visual information that attempted to persuade others about one's own positive qualities, Mehdizadeh assessed facial expression (striking a pose or making a face) and picture enhancement (using photo editing software) in the main photo and 'view photos of me' sections.
Further, she examined the use of positive adjectives, self-promoting mottos, and metaphorical quotes in the 'about me' section. Self-promotion in the notes section could include posting results from Facebook applications including 'my celebrity look-alikes,' which compares a photo of the user to celebrities, or vain online quiz results.
After this, she used the Rosenberg Self-Esteem Scale to measure participants' self-esteem. Narcissism was assessed by using the Narcissism Personality Inventory, according to a university release.
From the gender perspective, Mehdizadeh says she found that men displayed more self-promotional content in the 'about me' and notes sections, whereas women demonstrated more self-promotion in the main photo section.
"I thought this was an interesting way to apply theoretical paradigms in psychology to online self-presentation, which is still a fairly new concept," says the Canadian researcher.
"I believe the next question to be answered is whether or not the use of such websites could be used to improve one's self-esteem and overall sense of well-being. This sort of finding may have great implications in the lives of the socially anxious or depressed,'' according to the researcher.
The study has been published in the journal Cyberpsychology, Behavior, and Social Networking.

Fuel-free space tethers to manoeuvre spacecraft in orbit

A team at Nasa is testing a chemical-free propulsion system that will use Earth's magnetic field to move satellites and spacecraft in orbit.
Space tethers collect current when they fly near the ionosphere — the charged, upper layer of atmosphere — and magnetic field. The current flowing through the wire will be pushed on by Earth's magnetic field, creating a force that can be used to raise or lower a spacecraft's orbit.
Currently, satellites in Earth’s orbits have to periodically re-boost themselves owing to constant degradation of their orbits due to friction from colliding with atmospheric particles. The satellites have a limited supply of fuel for thruster rockets. When the gas runs out, the spacecraft's days are numbered.
A tether could lower a satellite's orbit so that it could, for example, more quickly re-enter Earth's atmosphere at the end of its operational life and avoid becoming another piece of space debris.
"We want to demonstrate a tether propulsion system that someone can just go and copy it, and fly it," Discovery News quoted Les Johnson at Nasa, as saying.
"We really are interested in casting a wide net. We're not going to specify the precise technology to be demonstrated," NASA''s chief technology guru Bobby Braun said.
 

High-speed graphene transistors could mean faster mobiles, computers

A group of UCLA researchers has fabricated the fastest graphene transistor to date, which could translate into faster electronic devices such as radios, computers and mobiles.
Graphene, a one-atom-thick layer of graphitic carbon, has the highest known carrier mobility making it a great candidate for high-speed radio-frequency electronics.
The UCLA team has developed a new fabrication process for graphene transistors using a nanowire as the self-aligned gate. Self-aligned gates are devices used to amplify and switch electronic signals and were developed to deal with problems of misalignment encountered because of the shrinking scale of electronics.
"First, it doesn't produce any appreciable defects in the graphene during fabrication, so the high carrier mobility is retained,” Nature quoted Xiangfeng Duan as saying.
“Second, by using a self-aligned approach with a nanowire as the gate, the group was able to overcome alignment difficulties previously encountered and fabricate very short-channel devices with unprecedented performance," he added.
These advances allowed the team to demonstrate the highest speed graphene transistors to date, with a cut-off frequency up to 300 GHz.
"We are very excited about our approach and the results, and we are currently taking additional efforts to scale up the approach and further boost the speed." said Lei Liao, a postdoctoral fellow at UCLA.
The paper is published September 1 in the journal Nature.

Google to play live interpreter using smartphones

The new software can translate simple statements uttered into an Android-enabled phone, with a short delay
Internet search giant Google unveiled new technology Tuesday that slowly interprets conversations between two people who do not speak the same language.
The software was demonstrated during a presentation by Eric Schmidt, chief executive of U.S.-based Google, at the IFA consumer-electronics trade show in Berlin.
Speaking in a country where privacy crusaders have attacked his company, Mr. Schmidt stressed the democratic benefits for a world where 3 billion to 4 billion people will soon have internet connectivity.
“These changes are happening so quickly that societies are not really prepared for what’s going to happen when everybody is online, everybody is posting information on what is going on around them,” he said.
“I also think in general this is very good, that it empowers citizens, that citizens are fundamentally good, that citizens fundamentally want to make their country a better place.” The new software, which can be installed on an internet-connected Android mobile phone, enables two people to utter simple statements into the same phone and hear a translation after a delay, but cannot be used for live telephone conversations between two places.
The software fetches the translations from a powerful language server run by Google. An assistant to Mr. Schmidt demonstrated it, translating a simple dialogue between German and English.

Star Tech: 'My transporter can run on any terrain'

Actor Neil Nitin Mukesh
My favourite Gadget: One of my favourite gadgets has to be my Segway. It’s a transporter I use to take me from one place to another. It is a beautiful machine; you just need to stand on it and it moves with your body weight. There are no gears, no shifts, nothing — just a machine with two wheels and 18-inch tyres. It can climb a mountain for you and also climb down for you; it can run on any terrain. It’s gorgeous.
Earlier, I found balancing on it a bit of a problem because you have to get used to it. But now I can teach anyone to ride on it in 10-15 minutes. I often ride it to my gym and to shoots too.
Why it's handy: If I’m shooting at Film City, I like to move about on it in between shoots. Film shoots sometimes happen at places where cars can’t go. So I just get on my transporter and get going.
I basically use it on days when action sequences are being shot and I have to run around a lot. I try to save my energy and use the transporter. When you do bloody action shots you need to change your clothes; so it’s better to have a transporter.
Gadget Fan: I decided to get one when I was shooting for a shoe ad. I saw the transporter with the steady-camera operator, Nitin Rao, and instantly fell in love with it. I am a gadget fanatic. I just mentioned it to my dad and he placed an order for it. I have no idea how much it would have cost him. I was in Bangkok when he told me about it. And when I came back, there it was in my home. I was overjoyed and have been using it ever since.

Samsung unveils iPad competitor Galaxy

Samsung Electronics Co. unveiled a new tablet PC named Galaxy Tab as the latest device meant to rival Apple Inc.’s popular iPad.
The device offers users “a new galaxy of possibilities” with features such as mobile video conferencing and a video chat function, Samsung Europe telecom executive Thomas Richter said Thursday at Berlin’s IFA consumer electronics fair.
The thin tablet device weighs 13.4 ounces (380 grams) and has a 7-inch (18-centimeter) touch screen, making it about three times that of an Apple iPhone, but roughly a third smaller than an iPad.
Richter said it comes with Google Inc.’s Android 2.2 operating system, which can run HTML5 and Adobe’s Flash Player - unlike the iPad.
The Galaxy will allow users to browse the web and check e-mail just as on a regular PC, Mr. Richter said.
“The Samsung Galaxy Tab has been designed to enable consumers to maximize their online experience wherever that may be,” the head of Samsung’s mobile communications business, J.K. Shin, said.
The price of the device will depend on telecommunications operators through which it will be available starting next month in Europe and later in fall in the U.S. and Asia, Samsung said.
The device supports Bluetooth, Wi-Fi and 3G cell phone networks, making it a combination of smart phone and laptop. It “turns out to be a perfect speakerphone on the desk, or a mobile phone on the move via Bluetooth headset,” Samsung said.
The tablet PC also comes with two cameras, one 3-megabyte digital camera with a flash on the back of the device, and a second camera on the front for video conferences - a feature the iPad lacks, but other competitors such as Dell’s Streak tablet PC also offers.
The company said that the device’s battery would support more than eight hours of continuous multimedia usage, or seven hours of video play.
The tablet also comes with Swype, a third-party application already found on Samsung’s Galaxy 5 series phone and available for some other Android-based handsets, which allows users to type on virtual keyboards by simply swiping fingers around from one letter to the next, lifting only between words.
The application then uses an algorithm to determine the word that is intended, which the company says allows for typing speeds of more than 40 words per minute.
Commercial success of the device will be crucial for the world’s largest maker of computer memory chips, flat screen TVs and liquid crystal displays.
Samsung’s quarterly profit surged by 83 per cent to a record high of 4.28 trillion South Korean won ($3.6 billion) in the second quarter ended June 30, but the company warned that intensifying competition in areas like mobile phones could dent earnings in coming quarters.
Samsung is the world’s second largest cell phone manufacturer after Nokia.

USB speakers set to get more out of laptops


AP The HP Pavilion dm4, left, the Sony Vaio, right, and the Samsung NB30 netbook. File photo
Soon, music aficionados can use plug-in USB speakers that produce high-quality sound from the laptop without the need for mains power.
The tinny fizz produced by most laptops’ built-in speakers spoils the music quality because the USB port, from which they get their power, can supply only 2.5 watts. Now, the British firm NXT of Cambourne, Cambridgeshire, has come up with a USB-powered system that can deliver up to 15 watts to each speaker, reports New Scientist.
Although power from mains-powered units is held at around 32 volts, a USB 2.0 port can deliver no more than 5.25 volts to a device.
NXT chief executive James Lewis says that most of the time music is quiet enough to be reproduced satisfactorily by circuits running at just 1 volt. So NXT built its USB-powered amplifier to run at low voltage, but able to deliver higher voltages - and more power to the speakers.
This is done by tapping a pair of capacitors that store spare power from the USB during quiet passages. By pre-determining the music signal a couple of milliseconds ahead of the amplifier, the system determines exactly when to raise the voltage and unleash the stored power.
“It’s the first time I’ve heard of using the dynamic reallocation of power for this type of application. It seems like a great idea,” said Andy Dowell, a director of Dolby Laboratories in the U.K. “People would love to get more oomph out of the PC speakers.”

Steve Jobs unveils upgraded AppleTV

Apple CEO Steve Jobs unveiled a new AppleTV device on Wednesday, saying that it would allow users to download and view an unprecedented variety of movies and TV shows.
The new device debuts four years after the company first introduced AppleTV, which Jobs acknowledged had not been a huge hit.
But Apple’s new push into providing TV and film content comes as rivals such as Google, Amazon, Sony and Netflix are all ramping up their efforts to provide streaming and downloadable content over the internet for viewing on televisions.
Sony announced earlier on Wednesday in Berlin that it would extend its Qriocity video-on-demand service to Europe soon.
Apple’s second generation device, priced at $99, offers viewers high-definition film rentals from all major Hollywood film studios at $4.99, and TV shows from ABC and FOX for 99 cents.
“We think the rest of the studios will see the light and get on board pretty fast,” Jobs said. The new AppleTV has a built-in power supply, HDMI, optical audio, Ethernet, and Wi-Fi, all packed into a device that is a quarter of the size of the previous generation hardware.
“It’s a fourth the size,” Mr. Jobs said. “You can hold it in the palm of your hand.” Mr. Jobs made the announcement at a San Francisco event in which he also unveiled a new line of iPods, an updated operating system for Apple’s mobile devices and a new version of iTunes that included a social networking feature called Ping that allows users to follow artists and share content and postings with friends.
Mr. Jobs claimed that Apple has sold 275 million iPods to date, but called the revamped products “the biggest change in the iPod line-up ever.” The changes include a slimmer iPod touch that includes both front and rear-facing cameras, an improved display and an ever smaller version of the iPod shuffle and a new square version of the iPod nano that replaces the device’s iconic scroll wheel with a touch-screen controller.

Submarines to employ new nanotube technology for sonar and stealth

Submarines need to probe ocean depths, and that too without being visible to enemies at times - both properties that they can now implement using new nanotube technology.
Speakers made from carbon nanotube sheets that are a fraction of the width of a human hair can both generate sound and cancel out noise - properties conducive to submarine technology.
Ali Aliev and colleagues explain that every time that an electrical pulse passes through the microscopic layer of carbon tubes, the air around them heats up and creates a sound wave.
Although Chinese nanoscientists were already aware of this property they did not test its ability to operate under water.
Mr. Aliev’s group took that step, showing that nanotube sheets produce the kind of low-frequency sound waves that enable sonar to determine the location, depth, and speed of underwater objects.
They also verified that the speakers could be tuned to specific frequencies to cancel out noise, such as the sound of a submarine moving through the depths.
The study appears in appears in ACS’ Nano Letters.

Laser based missile defence for helicopters on the anvil

A new laser technology being developed at the University of Michigan and Omni Sciences, Inc. will protect helicopters in combat from enemy missiles.
“Our lasers give off a signal that’s like throwing sand in the eyes of the missile,” said Mohammed Islam.
These sturdy and portable “mid-infrared supercontinuum lasers” are being made using economical and off-the-shelf telecommunications fibre optics and could blind heat-seeking weapons from a distance of 1.8 miles away.
The robust, simple design can withstand shaky helicopter flight and their mid-infrared supercontinuum mode can effectively jam missile sensors.
They also give off a focused beam packed with light from a much broader range of wavelengths. And they are the first to operate in longer infrared wavelengths that humans can’t see, but can feel as heat. Heat-seeking missiles are designed to home in on the infrared radiation that the helicopter engine emits.
Because this new laser emits such a broad spectrum of infrared light, it can effectively mimic the engine’s electromagnetic signature and confuse any incoming weapons, Mr. Islam said.
“We’ve used good, old-fashioned stuff from your telephone network to build a laser that has no moving parts,” therefore being especially well suited for helicopters, Mr. Islam said.

India looks at South America for farming technology updates

India, looking to launch a second green revolution to boost its food security, has begun looking at distant South America where countries have been able to ramp up food production with new technology and farming methods. And to take lessons first-hand, Agriculture Minister Sharad Pawar will visit Argentina, Brazil and Mexico this month.
“India has much to learn from the best practices of South America, especially Brazil and Argentina,” R. Viswanathan, Indian Ambassador to Argentina, Uruguay and Paraguay, told IANS during a visit here.
The South American countries have overtaken the United States in soya production, accounting for 50 percent of global production, and significantly denting the American domination in the agri-business sector.
With large swathes of land in a sparsely populated region, which accounts for 26 percent of global freshwater reserves, South American nations have the highest yields per hectare.
For Indian companies, which have been looking at farmlands for their agri-business, there is another attraction - the technologies that have been indigenously developed in these countries and applied in farming.
A revolutionary method is “no-till farming”, which is applied in 80 percent of the land cultivated in the Mercosur countries (a trading bloc comprising Brazil, Argentina, Uruguay and Paraguay,). In this kind of farming, land is not ploughed. Instead, the agricultural residue of the last plant is allowed to enrich the soil. The seed is then injected into the soil through special machines.
Another technology which Mr. Pawar is likely to see in Argentina is the Silobag - a polyeutherane bag that can store up to 200 tonnes of foodgrains on the field itself - that saves costs on building concrete storage units.
“We have brought this to the notice of the agriculture ministry,” said Mr. Viswanathan.
India faces a shortage of 15 million tonnes in storage capacity, one of the main reasons why hundreds of tonnes of food grains are wasted every year in the country. The technology figured at a meeting between Mr. Pawar and his Argentine counterpart, Julian Andres Dominguez here earlier last month.
Moreover, India can look to replicate the success of Argentina in turning agriculture into a high-technology sector.
Mr. Viswanathan referred to the Argentine group Los Grobos, which has brought the outsourcing model to agriculture. Los Grobos cultivates 270,000 hectares in Uruguay, Brazil and Argentina, without owning a single plot of land.
It uses “precision farming”, which employs software to determine the input distribution and monitors by satellite the location of the seeds and sprayer machines. At the same time, soil monitors give real-time information, helping the group head office to decide on the nutritional and other parameters.
All this could be brought to India for trial.
Also, Indian companies can move to the continent to take advantage of the available technology and expertise for business in the agricultural sector.
Mr. Viswanathan said Indian entrepreneurs should vigorously explore the region “since South America has an agri-business ecosystem like the IT ecosystem in India – export-oriented with competent human resources and service providers that allow investors to focus on output and returns.”
South America is a major source of oilseeds. It exports soya and sunflower oil worth $1 billion to India annually. It is learnt that the Indian delegation led by Mr. Pawar would explore increasing the supply of edible oil and pulses to the subcontinent as domestic output has not been able to meet galloping demand.

Internet crime in Tokyo hits record high in first half of 2010


AP A computer user is silhouetted in an Internet cafe. File photo
Police responded to a record 2,444 Internet crime cases nationwide in the first half of this year, a National Police Agency survey showed today.
The number, up 586 or 31.5 per cent from a year earlier, represented a new high since the NPA started gathering statistics for Internet crimes, defined as crimes which use a computer network, on a half-year basis in 2004.
Of the total, the number of fraud cases, such as swindling money from a successful bidder by posting false
information in an online auction, climbed 22.8 per cent to 867 cases.
The number of child pornography cases targeting children under 18 jumped 69.6 per cent to 329, a record high for any January-June period, while child prostitution cases increased 21.8 per cent to 212.
The number of child porn cases using the Internet accounted for more than half the total cases involving production and distribution of child pornography during the reporting period, according to the NPA.
The agency attributed the increase in the number of fraud cases partly to increased efforts by police.
The number of copyright infringement cases, including illegal distribution of films using file-sharing software,
came to 56, compared with none in the first half of 2009 and 75 in the second half of last year.
On the other hand, the number of unauthorized computer access cases, such as bidding in an online auction by using a false identity, plunged to 85 from 1,965 in the corresponding period of 2009.
The NPA, however, says the figures do not necessarily represent an improvement, because the previous year’s figure included a number of cases involving similar groups which repeatedly committed such crimes.

Texting in the U.S.: Not just for teens anymore


AP New Yorkers text as they wait on on Fifth Avenue. File photo
The thumb generation has got some company. A new study released Thursday found that fully 72 per cent of US adults now use text messaging - a form of communication that was once the nearly exclusive province of teenagers.
The study by the Pew Research Centre found that adults still have a long way to go to catch up to the texting habits of youths. Teens ages 12 to 17 send receive an average of 50 texts a day, while adult texters make do with just 10.
But the findings indicated a sharp rise in the last year in the number of adult texters - from 65 per cent to 72 per cent. However, the increased popularity has a downside: some 57 per cent of adults said they had received spam text messages on their cellphones.
The study found that nine in 10 cellular phone users said their devices make them feel safer and help them in arranging plans with friends and family. Indeed, 65 per cent of adults with phones have slept with their phones on or right next to their bed.
Adults are still far less likely to see their phone as an entertainment device, however. Some 60 per cent of teenagers said they used the phone to entertain themselves when bored, versus 39 per cent of adults.

Dark silicon chip to boost smartphone battery life

Researchers at University of California, San Diego are using “dark silicon” - the underused transistors in modern microprocessors - to improve smartphone efficiency.
Dark silicon refers to the huge swaths of silicon transistors on today’s chips that are underused because there is not enough power to utilize all the transistors at the same time.
The new GreenDroid chip prototype will deliver improved performance through the specialized processors fashioned from dark silicon that designed to run heavily used chunks of code, called “hot code,” in Google’s Android smartphone platform.
The UC San Diego computer scientists developed a fully automated system, which generates blueprints for specialized processors, called conservation cores, from source code extracted from applications.
GreenDroid conservation core uses 11 times less energy per instruction and produces an increase in efficiency of 7.5 times compared to an aggressive mobile application processor.
“Smartphones are a perfect match for our approach, since users spend most of their time running a core set of applications, and they demand long battery life,” said Steven Swanson at the UC San Diego Jacobs School of Engineering.
The computer scientists chose a smartphone for their chip prototype because mobile handsets are the new dominant computing platform. “Smartphones are going to be everywhere,” said Goulding, “We said to ourselves, ‘let’s make a prototype chip that saves energy on Android phones.’”

ISRO to attempt key test for new generation rocket on Sep 8

After a failed test six months ago, ISRO is making a fresh attempt on Wednesday to conduct long-duration static test of a crucial liquid core stage for a new generation heavy rocket which is being developed.
“The static test of crucial liquid core stage (L110) of GSLV Mk III launch vehicle (rocket) for 200 seconds is slated for 3 pm on September eight,” a senior Indian Space Research Organisation (ISRO) official told PTI here.
A top ISRO team, including Director of ISRO’s Liquid Propulsion Systems Centre (LPSC) S Ramakrishnan and Director of Vikram Sarabhai Space Centre (VSSC) P. S. Veeraraghavan, held a review meeting in Mahendragiri in Tamil Nadu yesterday and gave the go-ahead for the test.
Chairman of Bangalore-headquartered ISRO, K Radhakrishnan, is expected to witness the test at LPSC test facility in Mahendragiri, officials said.
ISRO conducted the test for 150 seconds at LPSC test facility on March five. While the test was originally targeted for 200 seconds it was stopped at 150 seconds since a deviation in one of the parameters - minor leakage in the command system - was observed.
A small leak in the command line was detected by computer, which automatically aborted the test. About 500 important parameters were monitored during the static test.
ISRO has since analysed the data.
GSLV Mk III rocket is being developed for launching four-tonne class of satellites in Geo-synchronous Transfer Orbit (GTO). Measuring 17 metres in length and four metres in diameter, L110 is an earth storable liquid propellant stage with propellant loading of 110 tonnes.
L110 stage uses two high-pressure Vikas engines in a clustered configuration and draws its heritage from the second stage of PSLV and GSLV and strapons of GSLV.
While in PSLV and GSLV, the liquid stage with single engine configuration burns for 150 seconds, the GSLV-Mk III requires burning for 200 seconds in a twin engine configuration.
India’s PSLV and GSLV so far used one Vikas engine. But the heavy-rocket GSLV Mk III under development needs much better thrust. And hence, two Vikas engines were being used for the first time, they said.
ISRO has already successfully conducted the short-duration static test of the L110 stage, which uses two high-pressure Vikas engines in a clustered configuration.
In January this year, ISRO also successfully conducted static test of its largest solid booster S200, which would form the strap-on stage for the GSLV Mk III, at Satish Dhawan Space Centre (SDSC), Sriharikota.
The successful test of S200 made it the third largest solid booster in the world, next to the RSRM solid booster of Space Shuttle and P230 solid booster of ARIANE-5.


Ferrari recalls 458 Italia supercars after fires

Ferrari says it is recalling 1,248 of its 458 Italia supercars after reports of fires breaking out in five of the luxury vehicles in several countries.
The Italian carmaker today said it wants to replace an adhesive that in some circumstances can melt due to overheating and possibly ignite.
Fires in the car that sells for euro197,000 ($ 253,000) have been reported in California, Switzerland, China and France.
Ferrari spokesman Stefano Lai says the company will be asking the owners of 1,248 cars produced before July 2010 to bring them in to have the glue replaced with mechanical fasteners.

With 21m visitors, Facebook beats Orkut in India


New Delhi, Aug. 25: Facebook has beaten competitors like Orkut and Yahoo! to become the top social networking site in India with 20.9 million visitors in July this year, according to research firm comScore.
India, which was one of the few countries where Orkut retained the top spot amongst social networking websites, now has more people logging on to Facebook.
Facebook.com has grabbed the number one ranking in the social networking category for the first time in July with 20.9 million visitors, up 179 per cent versus year ago, comScore said in a statement.
Compared to this, Google's social networking platform registered a growth of just 16 per cent with 19.9 million visitors in July.
This was followed by BharatStudent with 4.4 million visitors (up three per cent) and Twitter.com (3.3 million), while Yahoo! owned two of the top ten social networking sites: Yahoo! Pulse (3.5 million visitors) and Yahoo! Buzz (1.8 million visitors).
According to the report, more than 33 million Internet users (aged 15 and older) in India visited social networking sites in July.
With this, India now ranks as the seventh largest market worldwide for social networking, after the US, China, Germany, Russia, Brazil and the UK.
“The social networking phenomenon continues to gain steam worldwide, and India represents one of the fastest growing markets at the moment,” comScore Executive Vice President (Asia-Pacific) Will Hodgman said.
Though Facebook has tripled its audience in the past year to pace the growth for the category, several other social networking sites have posted their own sizeable gains, he added.
These numbers excludes access from Internet cafes or mobile phones and PDAs.

Now, a satellite traffic cop to prevent space collisions


Tobias Nassif is the vice president of satellite operations and engineering for Intelsat and a director of the newly formed Space Data Association,
The group provides advance notice of potential collisions so satellite operators can reposition their spacecraft before it's too late.
As more and more spacecraft are put into orbit, the chance of a collision increases as well, he added.
The prospect of an orbital crash seemed pretty remote until February 10, 2009, when an obsolete Soviet-era satellite called Cosmos 2251 ploughed into a working commercial telecommunications satellite owned by Iridium.
It generated more than 1,700 pieces of debris that were large enough to be tracked by radars on Earth. Ninety-six per cent of the junk remains in orbit today.
"Just having the contact information among the operators might help mitigate the possibilities of collisions in space," Discovery News quoted Nassif as saying.
The group expects to be fully operationally by January, issuing not just warnings of potential collisions, but also ways to mitigate radio interference.
"The system really isn''t limited in the number of spacecraft that it can handle. We''re outreaching to all the operators and civil agencies," Nassif said.

Wonder conductors to keep your laptops and mobiles cooler


It’s a common phenomenon for laptops and mobiles to become blisteringly hot after an hour or two of use, but a new wonder conductor could change all that.
In the past five years, physicists Charles Kane and Eugene Mele of the University of Pennsylvania in Philadelphia have uncovered a new kind of material that can keep electrons on the straight and narrow, eliminating collisions and slashing the amount of heat produced.
They are called topological insulators and conduct electricity by harnessing a quantum-mechanical property of electrons called spin. Insulators are the very opposite of conductors: their electrons are tightly bound to atoms and the material resists the flow of electrical current, reports The New Scientist.
The electron revolves around the nucleus in an orbit, tied to it by a magnetic field from the passing nucleus. However, it has its own mini-field as a result of its quantum-mechanical spin. Spin is akin to the rotation of a spherical particle around its axis one-way or the other, and it creates a magnetic field either from its north to its south pole.
In materials where the spin-orbit interaction is strong, a spin-up electron will be deflected in one direction on encountering a nuclear magnetic field, while a spin-down nucleus will be deflected in the opposite direction - an effect dubbed the quantum spin Hall effect.
In a slice of the right material one atom thick, Kane and Mele showed, this would result in no conduction, as electrons deflected in opposite ways around adjacent nuclei would cancel each other out.
At the edge of the material, however, with no adjacent nucleus available on one side, the net result would be a flow of spin-up electrons in one direction around the edge, and a flow of spin-down electrons in the opposite direction.
