XBox to welcome Kinect 'hackers'

Microsoft is to open up its XBox Kinect technology to allow amateur software developers to experiment with it.

The company is to release a software development kit in the spring, which will give developers access to the secrets behind the technology.

For now it will only be for personal use, but Microsoft says it will release a commercial version in due course.

Kinect, which turns the player's body into a game controller, has been a big hit since it launched last November.

It has already captured the imagination of the hacker community, which has been demonstrating various uses for the technology, including 3D photography.

Microsoft is hoping that an army of smarter developers will now find more ways to take Kinect to the next level.

"As breakthrough technologies like these reach scale, the resulting creativity and invention will open up a whole new world of possibilities for computing," said Craig Mundie, Microsoft's chief research and strategy officer.

The announcement was made during an open day at Microsoft's research centre near Seattle.

The company is hoping that the success of Kinect, developed by its own scientists, can give it a greater presence in the home entertainment field.

Anonymous targets anti-gay church

Hacker group Anonymous appears to have singled out its next target - the controvesial anti-gay Westboro Baptist Church in the US.

An open letter, purporting to be from Anonymous, accused the church of bigotry and fanaticism.

It warned that Westboro's websites would be attacked if the congregation did not stop its public protests.

In a defiant response, the church said it would not be silenced, and urged Anonymous to "bring it".

Westboro Baptist Church has been widely condemned for its aggressive anti-gay campaigning.

A number of US states have passed legislation, banning Westboro's members from protesting close to military funerals.

The church's leader, pastor Fred Phelps, was banned from entering the UK by the Home Office in 2009.

Activist hackers

Anonymous is known for its "hacktivism", targeting individuals, companies and governments whose behavior it objects to.

The group recently crashed a number of Egyptian government websites, in support of the country's pro-democracy protests.

It also attacked several online companies that it believed had helped clamp down on Wikileaks' activity, including Paypal and Amazon.

Laying out its case against Westboro Baptist Church, the letter said: "We have always regarded you and your ilk as an assembly of graceless sociopaths and maniacal chauvinists & religious zealots, however benign, who act out for the sake of attention & in the name of religion".

Despite being posted on an Anonymous news site, there was some uncertainty surrounding the provenance of the letter.

Further messages on the same website questioned its authenticity.

The confusion is understandable, according to Graham Cluley from security firm Sophos.

"Anonymous is a headless organisation," he said.

Mr Cluley warned that its followers could potentially be led into mounting a major hack under false pretenses.

"There are dangers in future that someone may pose as Anonymous and say that they want an attack".

The Westboro Baptist Church issued a statement, branding Anonymous "a puddle of pimple-faced nerds".

It called the threat a "bad miscalculation", and appeared to goad Anonymous to action, with the phrase "bring it!".

The church's website, godhatesfags.com was unavailable.

New blood pressure device hailed

A device which can be worn like a watch could revolutionise the way blood pressure is monitored in the next few years, scientists say.

Researchers at the University of Leicester and in Singapore have developed a device to measure pressure in the largest artery in the body.

Evidence shows it gives a much more accurate reading than the arm cuff.

The technology is funded by the Department of Health and backed by Health Secretary Andrew Lansley.

It works by a sensor in the watch recording the pulse wave of the artery, which is then fed into a computer together with a traditional blood pressure reading from a cuff.

"Start Quote

This is a great example of how research breakthroughs and innovation can make a real difference to patients' lives"

End Quote Andrew Lansley Health Secretary

Scientists are then able to read the pressure close to the heart, from the aorta.

Professor Bryan Williams, from the University of Leicester's department of cardiovascular sciences at Glenfield Hospital, said: "The aorta is millimetres away from the heart and close to the brain and we have always known that pressure here is a bit lower than in the arm.

"Unless we measure the pressure in the aorta we are not getting an appreciation of the risks or benefits of treatment."

He said the device would "change the way blood pressure has been monitored for more than a century" and he expected the technology to be used in specialist centres soon, before being "used much more widely" within five years.

"The beauty of all of this is that it is difficult to argue against the proposition that the pressure near to your heart and brain is likely to be more relevant to your risk of stroke and heart disease than the pressure in your arm," he said.

But it was important to ensure the new device was as small as possible to encourage clinicians and patients to use it, he added.

The research work was funded by the Department of Health's National Institute for Health Research (NIHR).

The NIHR invested �3.4m, with a further �2.2m of funding coming from the Department of Health, to establish a Biomedical Research Unit at Glenfield Hospital in Leicester.

The university collaborated with the Singapore-based medical device company HealthSTATS International.

Dr Choon Meng Ting, chairman of HealthSTATS, said: "This study has resulted in a very significant translational impact worldwide as it will empower doctors and their patients to monitor their central aortic systolic pressure easily, even in their homes and modify the course of treatment for blood pressure-related ailments."

Mr Lansley said the device was "a great example of how research breakthroughs and innovation can make a real difference to patients' lives".

Judy O'Sullivan, senior cardiac nurse at the British Heart Foundation, said previous research had shown that measuring pressure close to the heart was a better indicator of the effectiveness of treatment for high blood pressure than the standard method.

"However, further research is needed before we can be certain of its superiority in the doctor's surgery," she said.

Pressure mounts over Apple subs

Pressure is mounting on Apple over subscription charges it plans to levy on some mobile content.

The company wants a 30% cut of payments for newspapers and other publications downloaded to its devices.

Anti-trust regulators in the US and Europe are reportedly poised to investigate the new pricing model.

Apple has defended the changes to its terms of business, saying the system is good for customers and will give publishers new opportunities.

Under Apple's plans, companies wanting to distribute their content to iOS devices - including the iPhone and iPad - would have to offer users the option of subscribing directly from their app.

One third of the selling price would then go to Apple.

Previously, users have been able to make their purchases through a web browser, effectively circumventing Apple, and handing all of the money to the publisher.

Including such web links within apps will be banned, from June 30th.

Angry publishers

The change has provoked widespread condemnation from content providers, who have called for an official investigation.

Following a meeting of around 60 European publishers on Thursday, the International Newspaper Marketing Association issued a statement warning: "publishers simply can't afford to invest in new technology, products and services when the platform charges them 30% of total revenue."

According to the Wall Street Journal, the United States Federal Trade Commission (FTC) is now examining whether Apple's plan breaches anti-trust rules.

If correct, those early stage anti-trust inquiries may not result in full investigations.

Apple has defended the new terms of business, saying that the retail model it offers is good for all concerned.

In a statement, Apple's chief executive Steve Jobs said: "We believe that this innovative subscription service will provide publishers with a brand new opportunity to expand digital access to their content onto the iPad, iPod touch and iPhone."

However the company declined to comment directly on the publishers' criticism.

Fears are also being expressed that the charges will not be limited to newspaper and magazine subscriptions.

Apple has said that the 30% figure will apply to all in-app subscriptions.

They would mean the likes of Spotify, whose current app lets users launch a browser window to become new subscribers, would lose a large portion of its mobile revenue.

"Taking a 30% toll amounts to a massive increase in the cost basis of a content business that will kill it," said James McQuivey, an analyst with Forrester Research.

Ultimately, Apple has the entire media business in its sights, he said.

Media control

"In the end, Apple envisions a world in which people don't consume any kind of digital media without its help," added Mr McQuivey.

"Start Quote

The 10 per cent number is a shot across Apple's bow"

End Quote James McQuivey Forrester Research

He said that the charges are likely to encourage publishers on to other platforms.

One such alternative comes from Google, which also produces operating systems for smartphones and tablet computers.

Its recently announced One Pass payment system for magazine and newspapers charges a 10% fee, undercutting Apple.

One Pass also gives publishers greater freedom to offer different deals though different channels and to maintain a close relationship with their subscribers.

"You've got a very publisher-friendly approach; we basically don't make any money on this," Eric Schmidt, Google's chief executive said.

"The most important thing is to get the money to people who are producing high-quality content".

Google's cut was simply to cover its costs, Mr Schmidt added.

Warning shot

Even that lower figure may be too much for subscription services, said Mr McQuivey.

"The 10% number is a shot across Apple's bow, but it's still not low enough to sustain the market," he told BBC News.

A more realistic level would be on a par with the rates credit card processing companies charge, he added.

But both Apple and Google could be in for a shock, according to Mr McQuivey.

Media firms may give up on the app-based model of distributing content in favour of a new breed of web-based services, he said.

"It's going to be a pain, but everyone can now clearly see that in an HTML5 world, they won't have to pay taxes every single time they deliver value to consumers," he added.

Obama 'friends' Mark Zuckerberg

US President Barack Obama has met Silicon Valley bosses, including Facebook founder Mark Zuckerberg.

Apple's Steve Jobs and Google chief executive Eric Schmidt were also present at the private get-together in California.

The president had been seeking the views of technology leaders as he works to turn around his country's ailing economy.

Mr Obama has said he wants to encourage American businesses to invest more money in innovation.

Among those meeting the president were the bosses of Twitter, Yahoo and Oracle.

Apple's chief executive Steve Jobs was in attendance, despite media reports that his health had taken a turn for the worse.

US newspaper the National Enquirer published pictures, said to be of Mr Jobs, looking emaciated.

He is currently on his third medical leave of absence from Apple since being diagnosed with pancreatic cancer in 2004.

Thursday's meeting with the president was a private event, hosted by venture capitalist John Doerr.

Scientists build first anti-laser

Physicists have built the world's first device that can cancel out a laser beam - a so-called anti-laser.

The device, created by a team from Yale University, is capable of absorbing an incoming laser beam entirely.

But this is not intended as a defence against high-power laser weapons, the researchers said.

Instead they think it could be used in next-generation supercomputers which will be built with components that use light rather than electrons.

Professor Douglas Stone and colleagues at Yale University had initially been developing a theory to explain which materials could be used as the basis of lasers.

Strange lasers

Recent advances in laser design have resulted in a number of unusual devices that do not fit the traditional concept of a laser, Professor Stone explained.

"So we were working on a theory that could predict what could be used to form a laser," he said.

That theory also predicted that instead of amplifying light into coherent pulses, as a laser does, it should be possible to create a device that absorbs laser light hitting it, said Professor Stone - an anti-laser.

The have now succeeded in building one.

Their device focuses two lasers beams of a specific frequency into a specially designed optical cavity made from silicon, which traps the incoming beams of light and forces them to bounce around until all their energy is dissipated.

In a paper published in the journal Science they demonstrated that the anti-laser could adsorb 99.4 per cent of incoming light, for a specific wavelength.

Light speed

Altering the wavelength of the incoming light means that the anti-laser can effectively be turned on and off - and that could be used in optical switches, Professor Stone told BBC News.

Building something which can absorb light over a wide range of wavelengths is pretty simple, said Professor Stone, but only doing so for a particular wavelength makes the anti-laser potentially useful in optical computing.

The anti-laser's big advantage is that it is built using silicon, which is already widely used in computing.

It would not, however, be much use as a laser shield, according to Professor Stone.

"The energy gets dissipated as heat. So if someone sets a laser on you with enough power to fry you, the anti-laser won't stop you from frying," he said.

<!-- end of the embedded player component --> <!-- Player embedded -->

IBM's supercomputer Watson has trounced its two competitors in a televised show pitting human brains against computer bytes.

After a three night marathon on the quiz show Jeopardy, Watson emerged victorious to win a $1million (�622,000) prize.

The computer's competitors were two of the most successful players ever to have taken part in Jeopardy.

But in the end their skill at the game was no match for Watson.

Ken Jennings had previously notched up 74 consecutive wins on the show - the most ever - while Brad Rutter had won the most amount of money, $3million (�1.9m).

"I for one welcome our new computer overlords," Mr Jennings wrote along with his correct final Jeopardy question.

Search for meaning

But the victory for Watson and IBM was about more than money. It was about ushering in a new era in computing where machines will increasingly be able to learn and understand what humans are really asking them for.

Jeopardy is seen as a significant challenge for Watson because of the show's rapid fire format and clues that rely on subtle meanings, puns, and riddles; something humans excel at and computers do not.

On the night of the grand finale, IBM announced a research agreement with speech recognition firm Nuance Communications, to "explore, develop and commercialise" the Watson computing system's advanced analytics capabilities in the health care industry.

The technology behind Watson has the ability to scan and analyse information from many more resources than a human can in a short period of time, potentially aiding doctors in diagnosing patients quickly.

"We can transform the way that health care professionals accomplish everyday tasks by enabling them to work smarter and more efficiently," said Dr John E Kelly III, senior vice president and director of IBM research.

Other possible applications for Watson's technology include dealing with big sets of data commonly found in the legal and financial worlds.

Fair fight

There is little doubt that Watson's win stirred up a host of emotions.

Paul Miller of the technology blog Engadget.com was moderately impressed.

"Start Quote

I was rooting for the humans"

End Quote Daniel Terdiman CNet.com

"It's obvious that IBM's DeepQA research programme has developed some of the most sophisticated natural language AI known to man. At the same time, Jeopardy questions aren't really that hard... all three contestants knew the answer most of the time, but Watson was just quicker on the draw.

"Of course, it's no surprise that computers have quicker reflexes, so why shouldn't Watson get to use his inbuilt advantage to the utmost? It seems like a fair fight to us."

Daniel Terdiman of news website CNet watched the final with IBM staff at an event at the company's Silicon Valley research centre.

"I was rooting for the humans," he said.

Who is Bram Stoker?

Twitter was alight with praise and condemnation for the machine's victory.

The comments ranged from "Robot Apocalypse, here we come" to "IBM's Watson dominates Ken Jennings, turns attention to plotting our demise".

One user wrote: "next challenge for #Watson: The Price is Right".

The final Jeopardy category was 19th century novelists.

And the answer: William Wilkinson's "An Account of the Principalities of Wallachia and Moldavia" inspired this author's most famous novel.

The question - which all three contestants got right was "Who is Bram Stoker?"

Watson wagered $17,973 (�11,154) to cement his victory.

In the end Watson accumulated $77,147 (�47,923) versus Mr Jennings' total of $24,000 (�14,907) and Mr Rutter's $21,600 (�12,416).

Google unveils 10% One Pass fee

Google has launched a new payment system that allows users to subscribe to online content for a 10% commission fee.

The move comes after rival Apple was criticised over its payment system which takes 30% of the sale price.

One Pass will work on tablets and smartphones, as well as Google-related websites.

One Pass will launch initially in the UK, Canada, France, Germany, Italy and Spain.

The announcement came just one day after Apple announced new rules for publishers selling subscriptions on its iOS platform.

Apple says companies must now offer users the option to buy directly through an iTunes account, handing 30% of the price to Apple.

Previously, vendors were allowed to simply direct customers to an external website, keeping all of the profits.

On a Google blog posting, Lee Shirani, the company's director of business product management wrote: "Publishers can customise how and when they charge for content while experimenting with different models to see what works best for them."

Cyber crime &#39;costs �27bn a year&#39;

Cyber crime costs the UK economy �27bn a year, the government has said.

The figures, published for the first time, are a mid-range estimate and the real cost could be much higher.

They are made up of �21bn of costs to businesses, �2.2bn to government and �3.1bn to citizens.

Security minister Baroness Neville-Jones said the government was determined to work with industry to tackle cyber crime.

At the moment, cyber criminals are "fearless but they do not think they will be caught", she said in a briefing in central London.

'Frightening'

But efforts to get a grip on the problem had been hampered by firms who did not want to admit they had been the victims of attacks for fear of "reputational damage".

This also meant that it was difficult to accurately estimate the cost to the economy - and "worst case scenario" was likely to be much greater than �27bn.

"It is a bit like terrorism - the more you know the more frightening it looks," said Baroness Neville-Jones.

But she said the government was not at "panic stations", adding that it had a strategy to tackle the problem and had committed �650m over the next four years to it.

Prime Minister David Cameron and Foreign Secretary William Hague had met the bosses of some of Britain's biggest businesses, including Barclays, HSBC, Tesco and BA, on Monday to urge them to take the problem more seriously.

Baroness Neville-Jones said ministers would be unveiling a plan to disrupt cyber criminals and ensure more of them were prosecuted "in the spring" and had agreed to form a joint working group with industry to tackle the problem.

Martin Sutherland, chief executive of Detrica, the consultancy which compiled the report with the Cabinet Office, said the perpetrators of cyber crime ranged from "state-sponsored" activists to organised crime gangs down to "spotty teenagers sitting in their bedrooms".

Nearly half of the �21bn cost to business was made up of intellectual property theft - which included illegal downloading and file sharing. But industrial espionage, such as the theft of designs and commercial secrets, was also a significant problem.

The hardest-hit sectors were pharmaceuticals, biotech, electronics, IT and chemicals.
