Facebook and Twitter get closer

Facebook members will soon be able to pipe their profile directly to a connected Twitter account.

The social networking giant said it was working on the feature in a document sent to developers about upcoming changes.

Before now linking to Twitter was only possible from Facebook pages which are meant for bands, public figures and businesses.

Facebook said linking was coming "soon" but gave no specific date.

The mention of the forthcoming connection to Twitter came as Facebook unveiled its "subscription" system which works in a similar fashion to Twitter's "follower" feature.

Those who subscribe to a Facebook page, and eventually a profile, will automatically be informed when its owner publishes what they flag as a public update.

The feature changes the dynamic of Facebook which before now has been about sharing updates with those a user deems to be their "friends". By subscribing, Facebook members will be able to see the public activities of almost any of its 600 million users.

Many suspect the feature that links profiles to Twitter will be formally unveiled at Facebook's F8 developers conference which starts on 22 September.

The move is widely seen as a response to a change made by Twitter. In early September, Twitter made it easier to send Tweets directly to a Facebook account.

Prior to the changes, many Twitter and Facebook users relied on stand alone applications or add-ons to link the two.

Both the changes are also seen as responses to the success of the Google + social network which makes it easier to send updates to other places.

Blood vessels made on 3D printer

Artificial blood vessels made on a 3D printer may soon be used for transplants of lab-created organs.

Until now, the stumbling block in tissue engineering has been supplying artificial tissue with nutrients that have to arrive via capillary vessels.

A team at the Fraunhofer Institute in Germany has solved that problem using 3D printing and a technique called multiphoton polymerisation.

The findings will be shown at the Biotechnica Fair in Germany in October.

Out of thousands of patients in desperate need of an organ transplant there are inevitably some who do not get it in time.

In Germany, for instance, more than 11,000 people have been put on an organ transplant waiting list in 2011 alone.

To make sure more patients receive these life-saving surgeries, researchers in tissue engineering all over the globe have been working on creating artificial tissue and even entire organs in the lab.

But for a lab-made organ to function, it needs to be equipped with artificial blood vessels - tiny and extremely complex tubes that our organs naturally possess, used to carry nutrients.

Numerous attempts have been made to create synthetic capillaries, and the latest one by the German team seems to be especially promising.

"The individual techniques are already functioning and they are presently working in the test phase; the prototype for the combined system is being built," said Dr Gunter Tovar, who heads the BioRap project at Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart.

Elastic biomaterials

3D printing technology has been increasingly used in numerous industries, ranging from creating clothes, architectural models and even chocolate treats.

But this time, Dr Tovar's team had a much more challenging printing mission.

To print something as small and complex as a blood vessel, the scientists combined the 3D printing technology with two-photon polymerisation - shining intense laser beams onto the material to stimulate the molecules in a very small focus point.

The material then becomes an elastic solid, allowing the researchers to create highly precise and elastic structures that would be able to interact with a human body's natural tissue.

So that the synthetic tubes do not get rejected by the living organism, their walls are coated with modified biomoelcules.

Such biomolecules are also present in the composition of the "inks" used for the blood vessel printer, combined with synthetic polymers.

"We are establishing a basis for applying rapid prototyping to elastic and organic biomaterials," said Dr Tovar.

"The vascular systems illustrate very dramatically what opportunities this technology has to offer, but that's definitely not the only thing possible."

Planet with double sunset found

A planet orbiting two suns - the first confirmed alien world of its kind - has been found by Nasa's Kepler telescope, the US space agency announced.

It may resemble the planet Tatooine from the film Star Wars, but scientists say Luke Skywalker, or anyone at all, is unlikely to be living there.

Named Kepler-16b, it is thought to be an uninhabitable cold gas giant, like Saturn.

The newly detected body lies some 200 light years from Earth.

Though there have been hints in the past that planets circling double stars might exist - "circumbinary planets", as they are known - scientists say this is the first confirmation.

It means when the day ends on Kepler-16b, there is a double sunset, they say.

'Stunning'

Kepler-16b's two suns are smaller than ours - at 69% and 20% of the mass of our Sun - making the surface temperature an estimated -100 to -150F (-73 to -101C).

The planet orbits its two suns every 229 days at a distance of 65m miles (104m km) - about the same distance out as Venus.

The Kepler telescope, launched in 2009, is designed to scour our section of the Milky Way for Earth-like planets.

"This is really a stunning measurement by Kepler," said Alan Boss of the Carnegie Institution for Science near Washington DC, a co-author of the study.

"The real exciting thing is there's a planet sitting out there orbiting around these two stars."

Kepler finds stars whose light is regularly dimmed when an orbiting planet passes between the star and the telescope.

In this case, the team was also able to observe dimming when one star passed in front of the other.

Nasa's scientists saw additional dips in the light in both stars at alternating but regular times, confirming the dual orbit of the planet.

Data collected by the Kepler telescope allows for very precise measurements of the mass, radius and trajectories of all three bodies - the best ever estimates of a extra-solar planet.

The finding was reported in Friday's issue of the journal Science.

Low demand hurts Blackberry maker

Blackberry manufacturer Research in Motion (RIM) has seen its second-quarter profits more than halve, hurt by low demand for its older models.

The firm rolled out new smartphones but only late in the quarter.

Net profit fell to $329m (�208m) for the three months to 27 August, from $797m in the same period a year earlier.

In July, the company said it would cut 2,000 jobs - 11% of its workforce - as part of a shake-up of its operations.

Revenue for the second quarter fell to $4.2bn, a drop of 10% on the same three months last year.

During the quarter, RIM shipped some 10.6 million Blackberry smartphones and about 200,000 Blackberry PlayBook tablets, which was well below analysts' expectations.

Following the results announcement, RIM's shares fell by as much as 10% in after-hours trading in New York.

The Canadian firm said it expected things to improve in the third quarter though, forecasting shipments of between 13.5 million and 14.5 million smartphones and revenues of between $5.3bn and $5.6bn.

Web pirates readying block-buster

Usenet indexing site Newzbin2 is readying software it claims will defeat attempts to stop people visiting it.

In July, BT was ordered to block access to Newzbin2 after legal action by the Motion Picture Association (MPA).

The MPA said the member-only Newzbin2 site brings together pirated movies and music put on Usenet discussion boards.

The block is to be enforced via BT's Cleanfeed system which is more usually used to stop people visiting sites that peddle images of child sex abuse.

Before the block goes into effect in mid-October, programmers who work for Newzbin2 have been working on software they claim will be able to defeat the blocking system.

On 14 September, the first version of the Windows program Newzbin2 members will use to get at the site was released. Versions for Apple's OSX and Linux are planned.

According to file-sharing news site TorrentFreak, Newzbin2 is not willing to reveal how the code attempts to get around the Cleanfeed block.

However, TorrentFreak ran some tests using network sniffing software and found that the program relies on encryption to hide communication between users and Newzbin2.

Another technique it uses is to route all traffic through a well-established system known as TOR, which masks the identity of users and what they are trying to look at.

A spokesman for BT declined to comment on the development. He added that the specifics of the court-ordered block were still being debated.

Sites such as Newzbin2 have become more popular as people keen to get at pirated content move away from better known file-sharing technologies.

The original Newzbin was shut down via an earlier court case but its successor avoided that sanction by setting up shop outside UK jurisdiction.

FBI tackles celebrity photo leaks

The FBI is investigating computer hacking attacks on celebrities after photos which appear to show Scarlett Johansson nude were posted online.

The images, apparently taken by the actress, follow the leaking of naked photos of stars including Jessica Alba.

The FBI said it was investigating "the person or groups responsible for a series of computer intrusions involving high-profile figures".

A spokeswoman for Johansson was not available for comment.

Hacked photos of Justin Timberlake and his Friends With Benefits co-star Mila Kunis have also appeared online, according to reports.

Laura Eimiller, of the FBI's Los Angeles office, said dozens of stars had been the victims of hackers who had stolen personal information from email and other accounts.

She did not name any alleged victims "due to the pending nature of our investigation".

One leaked photo appears to show Johansson topless on a bed while another apparently shows her wearing a towel while revealing her bottom.

According to US celebrity website TMZ.com, Johansson has contacted the FBI over the leak.

TMZ also reports that her lawyer has sent letters to websites stating that Johansson owns the copyright to the pictures and threatening legal action if they are not removed.

Hunt outlines anti-piracy plans

UK Culture Secretary Jeremy Hunt has delivered a hard-hitting speech, calling on net firms, advertisers and credit card companies to cut ties with websites that link to unlawful content.

In a speech to the Royal Television Society, he said he wanted to make it harder for such sites to prosper.

Ideally the government would like to see Google remove pirate sites from its search engine completely.

But Google's response suggested this was unlikely.

"Without a court order, any copyright owner can already use our removals process to inform us of copyright infringing content and have it removed from Google Search," the firm said in a statement.

More difficult

It may not be enough for Mr Hunt, who appeared to be on an anti-piracy crusade.

In his speech, he denied that blocking access to pirated content was an attack on net neutrality.

"Unlawfully distributing copyrighted material is theft - and a direct assault on the freedoms and rights of creators of content to be rewarded fairly for their efforts," he said.

"We do not allow certain products to be sold in the shops on the High Street, nor do we allow shops to be set up purely to sell counterfeited products. Likewise we should be entitled to make it more difficult to access sites that are dedicated to the infringement of copyright," he added.

Many of the changes mooted by Mr Hunt are destined for the new Communications Act which is due to become law towards the end of the current Parliament in 2015.

Suggested measures include:

  • A cross-industry body, perhaps modelled on the Internet Watch Foundation, to be charged with identifying infringing websites against which action could be taken
  • A streamlined legal process to make it possible for the courts to act quickly
  • A responsibility on search engines and ISPs to take reasonable steps to make it harder to access sites that a court has deemed contain unlawful content or promote unlawful distribution of content
  • A responsibility on advertisers to take reasonable steps to remove their advertisements from these sites
  • A responsibility on credit card companies and banks to remove their services from these sites.

The hope is that the tough new measures will sit alongside the already controversial anti-piracy legislation outlined in the Digital Economy Act (DEA).

The DEA remains in a state of suspended animation as the government waits for the European Parliament to approve changes to it.

For its part, Google said that it felt that its current anti-piracy policies were sufficient.

It operates a takedown process in which it removes links identified as infringing copyright. Last year it removed three million items from its search engine.

The company said that it had improved takedown times with an average response of four hours. It is also set to change its auto-complete tool to eradicate terms associated with piracy.

Expensive nightmare

Jim Killock, chief executive of the Open Rights Group, said the proposals set a dangerous precedent.

"It is pretty dangerous to ask credit card companies or Google to decide who is guilty," he said.

"Once again Mr Hunt has listened to the lobbyists and has made no attempt to work out the scale of the problem. We are back where we were with the DEA, which is proving unworkable and an expensive nightmare," he said.

Other measures announced in Mr Hunt's speech included a promise to establish a new regulatory framework for the newspaper industry.

He said a cross-media approach to regulation was vital, as broadcasters, newspapers and internet companies developed new products for smartphones, tablet computers and web TV.

In the wake of the phone-hacking scandal, the public would demand a "robust" solution and he called on the industry to come up with one.

"Our free press has served us incredibly well. So we don't want any changes to result in the back-door imposition of statutory broadcast-style regulation. But if we are to avoid this, the public will insist on a system of robust, independent regulation with credible sanction-making power," he said.

He also spoke about the broadband landscape. He said the government's ambition to make the UK the best place for broadband in Europe by 2015 was on track. But, with countries such as Singapore introducing speeds of up to 1 gigabit per second as standard, it wasn't enough.

He said that plans for other firms to share BT's poles and ducts were "taking too long" and pledged to speed up the process.

Microsoft shows off next Windows

Microsoft has taken the wraps off the next generation of its Windows operating system.

Windows 8 is designed to run on tablet computers, as well as desktop and laptop PCs.

The software, which is due to be released in 2012 will work on the popular ARM-designed low power processors for the first time.

Microsoft has been under pressure to come up with an answer to Apple's iOS and Google's Android platforms.

Unveiling Windows 8 at the Build developers' conference in California, Windows division president Steven Sinofsky declared: "We re-imagined Windows. From the chipset to the user experience."

The system will function through one of two interfaces; a traditional desktop, similar to that seen in previous editions of Windows, and a tablet version, known as Metro.

Metro features larger, chunky controls of the sort that best suit touchscreen use. The current lack of such an input method is widely seen as the reason why few Windows 7 tablets exist.

Microsoft said that it would also be launching its own online marketplace - the Windows Store - to sell downloadable applications.

Chip changes

One of the biggest innovations for Windows 8 will be its compatibility with processors designed by ARM holdings.

Chips based around the ARM architecture typically use very little power, and as a result are found in the vast majority of smartphones and tablets currently available.

To date, Windows devices have required Intel or Intel-compatible processors, with the exception of Microsoft's Windows Phone range.

ARM chips are likely to be predominantly used on Windows 8 Metro devices, and will require ARM-specific versions of applications.

The company has not given details on the chips that will be integrated into desktop and laptop machines.

Tapping into any section of the Windows market will be seen as a huge boost for Cambridge-based ARM Holdings.

The company faces growing competition in the mobile device sector since Intel launched its tablet and smartphone-focused Oak Trail chipset in April 2011.

Tapping into that particular market is seen as vital for hardware manufacturers, and software-makers, such as Microsoft, as the market for traditional computers continues to be eroded.

Industry analysts Gartner predicted in April that the global market for tablets would reach 70 million this year, and grow to 300 million in 2015.

Sales of desktops and laptops are expected to continue growing, but at a much slower rate than in the past.

Skynet seeks idle computer power

Idle home computers are being sought to help search through mountains of astronomical data.

The Skynet project involves using the spare processing capacity of computers as a giant, distributed supercomputer.

PC's joining Skynet will scour the data for sources of radiation that reveal stars, galaxies and other cosmic structures.

People who process the most data could win a visit to one of the observatories gathering data for the project.

Star searchers

The Skynet project is being run by the International Centre for Radio Astronomy Research (ICRAR) and it is seeking the help of thousands of PCs to analyse data.

One of the sources of data will be the Square Kilometre Array (SKA) that will use thousands of dish antennas to create the most sensitive sky watching instrument ever made.

A decision about where to build the �1.5bn SKA will be made in February 2012 and it will be sited in either Australia or South Africa.

While it will have its own cadre of supercomputers to analyse data, the SKA is expected to produce so much information that a system to filter this down to the most interesting samples will be needed. Skynet will be part of that large-scale filtering system.

"As we design, develop and switch on the next generation of radio telescopes, the supercomputing resources processing this deluge of data will be in increasingly high demand," said Professor Peter Quinn, director of ICRAR in a statement.

"SkyNet aims to complement the work already being done by creating a citizen science computing resource that radio astronomers can tap into and process data in ways and for purposes that otherwise might not be possible," he added.

Prior to the SKA being built and switched on, the computers joining ICRAR's Skynet will crunch data from current radio astronomy research projects.

Those signing up to help will download a small program that will get a computer looking through data when that PC is not being used for anything else.

ICRAR said the Skynet program was small and should not slow down any PC it is running on. Also, it said, data would be split into small packets to ensure it did not swamp a participant's net connection.

Distributed computing projects that harness idle machines are a well-established way of scouring through research data. One of the earliest looked through radio signals for evidence of extra-terrestrial intelligence.

More recent projects simulate protein folding and help physicists search for the Higgs boson - the missing piece of what is known as the Standard Model, the most widely accepted theory of particle physics.

Legal action on college book plan

Writers from Australia, Britain and Canada are suing five US universities for creating online libraries made up of millions of books scanned by Google.

They argue that the books were digitised without authorisation.

The lawsuit accuses the universities of "engaging in one of the largest copyright infringements in history".

The case could have implications for the long-running court battle between Google and publishers.

Abducted?

The lawsuit centres on the HathiTrust repository, set up by the University of Michigan to allow students and university staff members access to so-called orphan works.

Orphan works are defined as out-of-print books whose writers could not be located.

The other universities named in the lawsuit are the University of California, the University of Wisconsin and the universities of Indiana and Cornell.

Paul Courant, the dean of libraries at Michigan University, told the AP newswire he was surprised by the lawsuit.

"I'm confident that everything we're doing and everything we're contemplating doing is lawful use of these works," he said.

He said that Google had so far digitised about five million books from Michigan's library, with several million more to scan.

But authors are convinced that the project is a massive infringement of copyright.

"This group of American universities has no authority to decide whether, when or how authors forfeit their copyright protection. They aren't orphaned books, they're abducted books," Angelo Loukakis, executive director of the Australian Society of Authors told the AP news service.

His views were echoed by Daniele Simpson, the president of Canadian authors guild the Union Des Ecrivaines et des Ecrivains Quebecois.

"How are authors from Quebec, Italy or Japan to know that their works have been determined to be 'orphans' by a group in Ann Arbor, Michigan? If these colleges make up their own rules, then won't every college and university, in every country, want to do the same?" she asked.

Unfair advantage

Alongside the US Authors Guild and eight individual authors, the groups aim to prevent the first release of 27 works by French, Russian and American authors scheduled for October.

The authors said books from nearly every nation have been digitised, including thousands of works published in 2001 in China, France, Germany, India, Italy, Japan, Spain and the UK.

"This is an upsetting and outrageous attempt to dismiss authors' rights," said Mr Loukakis.

Mr Loukakis and Ms Simpson are among the authors involved in the lawsuit. Others include UK author Fay Weldon, poet Andre Roy and Shakespeare scholar James Shapiro.

The lawsuit comes ahead of the next hearing in the six-year battle between Google, the Authors Guild and the Association of American Publishers.

Lawyers for authors and publishers are due to go back to court in 10 days time to see if a new deal can be done with the search giant.

A $125m (�79m) royalties settlement was rejected by Judge Denny Chin who argued that the deal would give Google an unfair advantage.
