Germany lifts Doom ban after 17 years

A German ban on selling Doom to teenagers has been lifted after 17 years.

The classic video game was put on an index of controlled titles in 1994 as it was deemed likely to harm youth.

Like pornography, sales of the violent shoot 'em up were restricted to adult-only stores.

The rules have been relaxed because officials believe that Doom is now only of artistic and scientific interest and will not appeal to youngsters.

However, one version of the game remains on the index because it features Nazi symbols on some levels.

Sadistic violence

The restrictions on Doom and Doom II officially expired on 31 August following a meeting of the Federal Department for Media Harmful to Young Persons (Bundesprufstelle) earlier in the month.

The Bundesprufstelle reportedly decided to reconsider the game's status following an appeal by Bethesda Softworks, the current owner of iD Software, which created Doom.

Bethesda argued that the game's crude graphics had been surpassed by many modern titles and, as a result, the violence it depicted had far less of an impact.

In a document detailing its reasons, the Bundesprufstelle said its original decision was not solely based on the graphic quality of the game, although it noted that most mobile phones now supported far more realistic images.

The panel explained that it was originally concerned because the story played out in Doom involved a relentless cycle of gunplay and "bloody sadistic" violence.

The Bundesprufstelle said it had relaxed the restrictions because Doom was now "mainly of historical interest" and was far less likely to be played by children. Not least, it added, because much more realistic and challenging games were more widely available.

Some members of the Bundesprufstelle panel wanted to keep the restrictions in place but were outvoted by those deeming it acceptable.

If Doom goes on sale in Germany it will still only be available to those aged 16 or over.

The adults only rule was beginning to look like an anomaly because other versions of Doom games, such as one for the Game Boy Advance, had previously been approved in Germany.

Restrictions on "Doom II - Hell on Earth" have also been lifted.

However, the panel decided to maintain controls on the American version of Doom II because it incorporates two levels from Wolfenstein 3D which makes use of Nazi symbols including swastikas.

Hologram microscope spots E. coli

A cheap holographic microscope capable of detecting E. coli and other bacteria has been developed by researchers in the US.

The handheld device uses a laser instead of lenses to identify bugs in water, food or blood, and costs less than $100 (�60) to build.

Images can be uploaded to remote computers for further analysis.

Scientists hope the technology will improve healthcare in areas that lack sophisticated diagnostic equipment.

Details of the microscope - created at the University of California, Los Angeles (UCLA) - were published in the journal Biomedical Optics Express.

Micro 3D

The device has two modes of operation: a "transmission" mode which can analyse liquids such as blood and water, and a "reflection" mode which produces holographic images of denser surfaces.

"Transmission mode is great for looking at optically transparent things like cells or very thin slices," explained Dr Karl Ryder of Leicester University's Advanced Microscopy Centre.

"However, if you want to look at more solid surfaces, you can't use transmission mode, because the light wouldn't get through."

In reflection mode, the microscope used holography to create a 3D image of the sample being studied.

"You take a laser and you split the beam in two using a mirror. Then you use one of these beams to illuminate your sample," said Dr Ryder.

"You can then recombine these two beams using clever mathematics to build a 3D image of your object."

Cheap chips

A key advantage of the design is that it employs cheap electrical components instead of heavy and expensive lenses.

"There are no optics at all in this system. They've made it really small, and they're looking at small sample sizes, so you don't need complex focusing," said Dr Ryder.

Instead, the microscope uses digital photo sensors commonly found in devices like iPhones and Blackberrys. These can cost less than $15 each to produce.

Despite its price, researchers claim that the microscope can help to monitor outbreaks of difficult-to-detect bacteria such as E. coli.

"It's a very challenging task to detect E. coli in low concentrations in water and food. This microscope could be part of a solution for field investigation," said Prof Aydogan Ozcan from UCLA.

The device captures raw data, but its simple design means that processing needs to be done on an external device with more computing power.

A user in the field can forward the image data to their mobile phone, a laptop PC, or even upload it to an internet server.

Prof Ozcan believes the microscope could prove invaluable for medics working in developing countries.

"With just a small amount of training, doctors could use devices like these to improve healthcare in remote areas of the world with little access to diagnostic equipment."

Codebreakers remember Tony Sale

Veteran codebreakers will return to Bletchley Park this weekend for the annual Armed Forces Weekend and Enigma Reunion.

The two-day event will also remember Tony Sale, the National Museum of Computing founder, who died this week.

Mr Sale was the mastermind behind the re-building of Colossus, the world's first operational computer.

"Tony was one of our best known characters," said Bletchley Park Trust director Simon Greenish.

"His contribution to the early days of the development of the trust, when the site was under very real threat of development, was fundamental and, without him, the Bletchley Park site and its hugely important history would not have survived."

Vital role

The event, which is open to the public, will look back at the role of the armed forces through history and the vital role Bletchley Park's codebreakers played during World War II.

About 100 former codebreakers are expected to attend the reunion, which will include a memorial service on Sunday.

"A lot of our veterans who knew Tony personally, and indeed his wife Margaret, will be attending the memorial service where we remember those who worked here at Bletchley Park, so tributes to Tony will certainly feature in that service," said Mr Greenish.

Other attractions will include a field gun run competition and a display by the Vintage Military Amateur Radio Society of radio equipment spanning the last 100 years, showing how communication in the armed forces has changed over time and become more vital.

World War II re-enactors dressed in uniforms and civilian costumes of the day will reflect the wartime era.

The weekend will also include flypasts by the Battle of Britain Memorial Flight (subject to weather conditions and aircraft serviceability).
