stronghawk writes "The creator of the Nickel-O-Matic is back at it and has now built a Turing Machine from a Parallax Propeller chip-based controller, motors, a dry-erase marker and a non-infinite supply of shiny 35mm leader film. From his FAQ: 'While thinking about Turing machines I found that no one had ever actually built one, at least not one that looked like Turing's original concept (if someone does know of one, please let me know). There have been a few other physical Turing machines like the Logo of Doom, but none were immediately recognizable as Turing machines. As I am always looking for a new challenge, I set out to build what you see here.'"

Cracked.com asked readers to Photoshop what life would be like in an Internet-addicted society learning to cope without it. Better hope it never happens, or be prepared for dry-erase message boards, carrier pigeon-powered Twitter, block-long lines to get into adult video shops, door-to-door Rickrolling, Lolcats on Broadway, and $199.99 CDs."

Scientists from the University of East Anglia are studying the potential health benefits of dark chocolate, and need 40 female volunteers who would like to eat chocolate every day for a year. The chocolate loving 40 must be post-menopausal and have type 2 diabetes so it can be determined if the flavonoid compounds in chocolate can reduce the risk of heart disease. Dr Peter Curtis, of the UEA's School of Medicine, said, "Our first volunteers are about to return for their final visit to see if the markers of heart health - such as blood pressure and cholesterol levels — have changed. A successful outcome could be the first step in developing new ways to improve the lives of people at increased risk of heart disease."

H. Beatty Chadwick has been in a staring match with the judicial system for the past 14 years, and the system just blinked. Chadwick was ordered to pay his ex-wife $2.5 million after their divorce. He refused to pay saying that he couldn't because he lost the money in a series of "bad investments." The judge in the case didn't believe him and sent him to jail for contempt. That was 14 years ago. Last week another judge let Chadwick go saying that "continued imprisonment would be legal only if there was some likelihood that ultimately he would comply with the order; otherwise, the confinement would be merely punitive instead of coercive." Chadwick, now 73, is believed to have served the longest contempt sentence in US history.

Several readers wrote in with news of the momentum gathering behind free access to government-funded research. A petition "to create a freely available virtual scientific library available to the entire globe" garnered more than 20,000 signatures, including several Nobel prize winners and 750 education, research, and cultural organizations from around the world. The European Commission responded by committing more than $100 million towards support for open access journals and for the building of infrastructure needed to house institutional repositories able to store the millions of academic articles written each year. In the article Michael Geist discusses the open access movement and its critics.

Andy Updegrove writes "A legislator in California has decided that it's time for California to get on the open formats bandwagon. If all of the bills filed in the last few weeks pass, California, Texas, and Minnesota will all require, in near-identical language, that 'all documents, including, but not limited to, text, spreadsheets, and presentations, produced by any state agency shall be created, exchanged, and preserved in an open extensible markup language-based, XML-based file format.' What type of formats will qualify? Again, the language is very uniform (the following is from the California statute): 'When deciding how to implement this section, the department in its evaluation of open, XML-based file formats shall consider all of the following features: (1) Interoperable among diverse internal and external platforms and applications; (2) Fully published and available royalty-free; (3) Implemented by multiple vendors; (4) Controlled by an open industry organization with a well-defined inclusive process for evolution of the standard.'"
