DVT linked to video gamer's death

30 July 2011 Last updated at 15:44 GMT Chris Staniforth died from DVT Chris Staniforth would spend up to 12 hours playing on the console. A man whose son died after playing video games for long periods is campaigning for greater awareness of the risk posed by their excessive use.

Chris Staniforth, 20, who would play his console for up to 12 hours, died in May from deep vein thrombosis (DVT).

His father David believes the condition may have been triggered by long gaming sessions.

DVT can form during long periods of immobility and can kill if the clots travel to the lungs.

Computer records showed his son would sometimes play online on his Xbox for periods up to 12 hours.

The coroner said a clot formed in Chris' left calf before moving to his lungs.

Once there, it caused a fatal blockage, known as a pulmonary embolism.

Mr Staniforth said: "After my research I saw there was no difference to Chris sitting at a desk on his Xbox and someone on a long-haul flight.

"Sitting still is literally the danger zone. Chris loved to play and would stay up all night.

"Millions of people worldwide are playing these games for hours, and there is a risk."

While Mr Staniforth has no problem with games consoles, he wants to highlight the heightened risk of DVT associated with being immobile, and is in the process of setting up a website.

In a statement, Microsoft, who manufacture the Xbox console, said: 'We have always encouraged responsible game play through our education campaigns such as Play Smart, Play Safe.

"We recommend that gamers take periodic breaks to exercise as well as make time for other pursuits."

Rocket vision

28 July 2011 Last updated at 07:11 GMT By Virginia Brown BBC News Magazine Chris Foss space illustration As the next generation of spaceships is being conceived, should shuttle designers take their inspiration from sci-fi illustrators?

Generations of schoolchildren, openly, and many adults, perhaps more guardedly, have delighted in fantastical depictions of space travel.

But the fanciful reputation of sci-fi novels and films aside, the illustration of spacecraft might actually have a realistic place in the design of future vessels.

The line has often been blurred between the realm of the sci-fi artist and the real spacecraft designers.

Often referred to as the father of modern space art, Chesley Bonestell had a significant impact on not only science fiction illustration, but the whole of the American space programme.

German rocket developer and champion of space exploration Dr Wernher von Braun, who was inspired by the works of Verne and Wells, commissioned Bonestell to illustrate his spaceflight concepts in a 1952 issue of Collier's Weekly magazine.

Spaceship from 2001: A Space Odyssey The epic film 2001: A Space Odyssey influenced Chris Foss and other space artists

The combination of von Braun's technology and Bonestell's artistic vision made the science come alive for the layman readers. Of course, the tax dollars and votes of those inspired layman readers would be needed to realise ambitious space projects.

The Association of Science Fiction & Fantasy Artists now honours work in the sci-fi and fantasy art industry with its annual Chesley Awards.

An enterprising company might achieve success by offering spaceships that resemble the unique visions of Chris Foss”

End Quote Dr Gary Westfahl Science fiction academic Harry Lange was a German artist who got his start in military flight manual illustrations and was appointed to lead the future projects section for Nasa. He and his team found themselves illustrating von Braun's ideas to promote his vision of a US space station. Lange ended up as production designer on Stanley Kubrick's 2001.

On the other hand it's hard to imagine the designs of Chris Foss, the subject of a new retrospective book, Hardware: The Definitive SF Works of Chris Foss, easily crossing the line into the real world of space travel. With Picasso as an inspiration, Foss created book covers that pioneered a new style of space art, featuring prominently placed gigantic colourful craft in swirling spacescapes.

Marked with mysterious symbols and complex patterns, his illustrations have breathed life into sci-fi writings of everyone from Isaac Asimov to EE "Doc" Smith and AE van Vogt. Foss was also commissioned to do work for Alien, Superman and Alejandro Jodorowsky's unmade film version of Dune.

Seeing Kubrick's 2001 made a lasting impression on his work, as did the Cold War years and the bleakness of some of the derelict areas of post-war Britain. "People were really looking for a new kind of explosion," says Foss. "Humans want hope. They want something to believe in."

So is it fanciful to imagine Foss's ships - or those of equally florid artists - being like Bonestell's and infiltrating real design?

Perhaps not if a new age of privately-financed space travel needs to rally support in the same way von Braun and Bonestell did.

The end of the space shuttle programme presents a new challenge for spacecraft engineers and designers - one that could even benefit from collaboration with artists.

With government funding constricted, many will be looking to private investors to lead the future of space vessels.

More and more, the aim of companies, such as Boeing, will be to entice consumers to pay for space travel. Just as airlines have done, they will have to appeal to potential passengers - and investors - in order to establish their brands against the competition.

"An enterprising company seeking to attract government and private passengers might achieve success by offering them spaceships that resembled the unique visions of Chris Foss," says science fiction academic Dr Gary Westfahl.

Exotic design might play a part similar to that of airline insignia - from Alaska Airlines' themed craft to Aer Lingus's shamrocks. The goal is to establish brand recognition and visual appeal.

"Foss made his spaceships beautiful not by streamlining them but by adding bright, decorative colours," says Westfahl.

Some might find it strange that a Nasa worker like Lange could make the jump from a deep space project to Hollywood and end up with Oscar nomination for the art direction on The Empire Strikes Back.

But space is a particularly romanticised part of our vision of exploration, says Dr Eric Rabkin, a professor of English at the University of Michigan who specialises in science fiction.

It's because of the unknown, he says. Trains must go where tracks have previously been laid down and planes have to fly where they can ultimately land.

"Ships are inherently romantic because they can go where no one has before. Ships are associated with freedom and conquest," says Rabkin.

Whitehall's web habits revealed

29 July 2011 Last updated at 11:47 GMT By Victoria King Political reporter, BBC News SexyMP, Facebook, Bears Faction and Doctor Who The list reveals the eclectic tastes and varied hobbies of civil servants Belly dancing, Doctor Who and the Roman Empire are just some of the interests of civil servants as revealed by their web browsing habits.

The Department for Transport (DfT) has disclosed the 1,000 sites visited most often by staff while at work.

The BBC website came top, but employees are also spending time apparently shopping, gambling and house-hunting.

A DfT spokesman said personal internet use by staff should be restricted to official breaks.

The details were published in response to a Freedom of Information request by campaign group the TaxPayers' Alliance. They cover the period from January to May this year.

'Leave reality behind'

Many of the websites come as no surprise - Google is close to the top along with a number of newspapers and news blogs. The BBC homepage is number one with 7.4 million hits.

Facebook comes in at 85th, with more than 130,000 hits. Argos is the most regular online shopping destination, but John Lewis, Next and Debenhams feature too.

Plenty of sports fans appear to have been sneaking in a cheeky look or two at scores or fixtures - with goonerweb, chelseaafc and espncricinfo - a cricket stats website - all popular.

It is vital taxpayers are able to scrutinise how time they are paying for is spent”

End Quote Matthew Sinclair TaxPayers' Alliance Some may also be having a flutter - hence the popularity of oddschecker and bet365 - which get 25,808 and 7,328 hits respectively.

But there are a number of unusual sites which reveal some more unexpected pastimes among civil servants.

Coming in at number 385 - with 27,634 hits - is bearsfaction.org.uk - a website run by the Lorien Trust which organises fantasy role-play festivals.

It invites users to "leave reality behind" and "walk amongst goblins, elves and dwarves".

Even more popular, coming in at 115, is etiquettehell.com which gives frustrated sticklers for good manners a forum in which to vent.

Smallworldbellydance.com - a south London belly dancing studio - gets 3,170 hits, while a website for fans of the Roman Empire attracted nearly 100,000.

Some civil servants also seem to be interested in matters of glamour within Whitehall itself.

Sexymp.co.uk - where users get to rank Members of Parliament in order of attractiveness - got 21,477 hits in the five-month period, making it the 465th most popular site.

Meal breaks

The TaxPayers' Alliance said it had contacted all government departments, but the DfT was the only one to provide the information.

Director Matthew Sinclair said: "While many staff work very hard, there have been enough anecdotal reports of time-wasters within the civil service that it is vital taxpayers are able to scrutinise how time they are paying for is spent.

"Other departments need to follow suit and publish this information. There is no practical obstacle to proper transparency."

The DfT was asked whether it could reveal the amount of time spent on each website, but it said it did not keep accurate figures.

A spokesman said: "Our internet access policy states that personal use of the internet by staff should be kept as short as possible and should not in any event exceed one hour each day made in their own time, e.g. meal breaks.

"We also have measures in place to prevent the inappropriate use of internet by staff, for example in relation to pornographic web sites.

"Personal use should not place excessive demands on ICT [information and communications technology] facilities and should not detract from staff's performance of their duties."

The DfT said two staff had been disciplined during 2009-10 due to "inappropriate internet usage".

Solar car put to wind tunnel test

29 July 2011 Last updated at 11:15 GMT By Jason Palmer Science and technology reporter, BBC News Nuon technical manager Mike Hoogstraten explains the aerodynamic tests

The best in solar car engineering can be heard on the wind.

At the German-Dutch Wind Tunnels in the Netherlands, an entry into this year's World Solar Challenge is being put to its final tests - and the results are both visible and audible.

The bi-annual contest is a gruelling race straight across Australia, covering more than 3,000km between Darwin and Adelaide.

More than 40 teams from 22 countries have applied for the 2011 race in October. The teams are only allowed to travel between 8am and 5pm, and must follow Australian road regulations and share the road with conventional cars.

The Nuon Solar Team from the University of Delft has won four of the last five Challenges, and their latest effort - dubbed Nuna 6 - is the lightest yet, weighing in at just 145kg.

But getting the weight down is just part of the battle, said Pier von Zonneveld, the project's team leader.

"Aerodynamics is a very important part of the design process," he told BBC News.

"There's a rule of thumb that states that about 70% of the friction that the car needs to overcome comes from aerodynamics. Of course we tested in wind tunnels in our design phase, but now we've actually built the car we want to test and see if these measurements are still accurate."

Ribbon test

A gale of wind, completely silent, whips through the tunnel, simulating the conditions of travel at 100km/h.

We're... showing the world these cars are really good - they can go extremely fast with very little energy. It's just an inspiration to future technology”

End Quote Mike Hoogstraten technical manager, Nuon Solar Team The car is strapped to the tunnel's floor, and high-precision scales measure the how much lift the car is experiencing. But for all the technology gathering data from the scales, two low-tech approaches are part of the tests.

What the team wants to know is whether there is "laminar flow" around the car - smooth, uninterrupted sheets of air.

If the precise shape of the car's surfaces and edges aren't perfect, the flow can be turbulent - swirling and chaotic, and creating a great deal of drag that squanders energy.

The team uses a microphone and amplifier to quite simply listen to the air - laminar flow is silent, whereas turbulent flow makes a noise.

And a ribbon on the end of a stick can show where the flow is turbulent flow is too; as it is brought close to the car's surfaces, the ribbon whips around wildly where the flow is turbulent, and hugs the shape of the car where it is laminar.

Mike Hoogstraten, the team's technical manager said that preparing for the race would entail far more than fine-tuning the car's aerodynamics.

"The design is one part of the deal - you have to make a good car. But once you get to Australia there's another part - strategy," he said.

"To win the race you have to make lots of calculations and predictions. You have to use the energy as efficiently as possible, by knowing how much energy you're going to get, and how much you're going to give away."

Nuna5 solar car The teams travel just nine hours a day and sleep alongside the Stuart highway in Australia

Those calculations even include weather modelling, a crucial aspect of a race that runs thanks only to the Sun.

The race's organisers tighten the regulations on the cars every year; the entries have become so refined that the contest simply needs to be made tougher.

This year, teams will have to use silicon solar cells - the type commonly found on roofs and used to power electronics - rather than the higher-efficiency gallium arsenide cells used previously.

The kind of engineering that is being worked out now, for nothing more than the glory of winning the race, will pay dividends in the development of solar-powered passenger cars.

"Our team doesn't believe that this kind of car is the commercial car - you can see by the size it'd be difficult to get your groceries from one place to another," Mr Hoogstraten said.

"But we're improving those technologies and using them and showing the world these cars are really good - they can go extremely fast with very little energy. It's just an inspiration to future technology."
