In an internet-based study published today on the website of the British Medical Journal, Australian investigators tested how well Googling could help to establish a difficult diagnosis. The search results met against their criteria in 15 out of 26 cases.

Previous anecdotes of the use of Google in reaching a difficult diagnosis are presented in the paper. In a case described in the New England Journal of Medicine (NEJM), a physician diagnosed IPEX syndrome after submitting the typical diagnostic clues to the search engine. A patient’s father replied to doctor’s saying that his son had acute subclavian vein thrombosis of unknown origin: “But of course hehas Paget-von Schrötter syndrome.”

Hangwi Tang and Jennifer Hwee Kwoon Ng from the Princess Alexandra Hospital in Brisbane selected clinical cases from the NEJM blind to the correct diagnosis. They selected 3 to 5 rather specific features, searched Google, and selected the 3 disorders from the results that seemed to fit the case best. If one of those was right, Google was said to be “right”.

The scientists admit that an internet search probably works better with specific symptoms rather than with phrases such as “fever ill pain”. Also, the percentage may depend on the operating physician’s knowledge base, and the test was not double-blind.

Experts commented that the internet is not a replacement for doctors, but should be seen as a way of supporting doctors and patients. A spokeswoman for the Patient Association added that “a lot of sites are not credible. There are lots of good sites out there, but we also know that there are many that are not credible.”

On Thursday, the municipal intermediate people’s court in Shijiazhuang, Hebei province, China pronounced sentences for 21 defendants implicated in the 2008 Chinese milk scandal which killed at least six infants and sickened nearly 300,000 others.

In the local court’s decision, 17 accused were indicted for the crimes of “producing, adding melamine-laced ‘protein powder’ to infant milk or selling tainted, fake and substandard milk to Sanlu Group or 21 other dairy companies, including six who were charged with the crime of endangering public security by dangerous means.” Four other courts in Wuji County, in Hebei, China had also tried cases on the milk scandal.

Zhang Yujun, age 40, of Quzhou County (Hebei), who produced and sold melamine-laced “protein powder” in the milk scandal, was convicted of endangering public security and sentenced to death by the Shijiazhuang intermediate people’s court.

The court also imposed the penalty of death upon Geng Jinping, who added 434 kg of melamine-laced powder to about 900 tons of fresh milk to artificially increase the protein content. He sold the tainted milk to Sanlu and some other dairy companies. His brother Geng Jinzhu was sentenced to eight years imprisonment for assisting in adding the melamine.

A suspended capital punishment sentence, pending a review, with two years probation, was handed down to Gao Junjie. Under the law, a suspended death sentence is equivalent to life imprisonment with good behavior. The court ruled that Gao designed more than 70 tons of melamine-tainted “protein powder” in a Zhengding County underground factory near Shijiazhuang. His wife Xiao Yu who assisted him, was also sentenced to five years imprisonment.

Sanlu Group General Manager Tian Wenhua, 66, a native of Nangang Village in Zhengding County, who was charged under Articles 144 and 150 of the criminal code, was sentenced to life imprisonment for producing and selling fake or substandard products. She was also fined 20 million yuan (US$2.92 million) while Sanlu, which has been declared bankrupt, was fined 49.37 million yuan ($7.3 million).

Tian Wenhua plans to appeal the guilty verdict on grounds of lack of evidence, said her lawyer Liang Zikai on Saturday. Tian testified last month during her trial that she decided not to stop production of the tainted milk products because a Fonterra designated board member handed her a document which states that a maximum of 20 mg of melamine was allowed in every kg of milk in the European Union. Liang opined that Tian should instead be charged with “liability in a major accident,” which is punishable by up to seven years imprisonment, instead of manufacturing and selling fake or substandard products.

According to Zhang Deli, chief procurator of the Hebei Provincial People’s Procuratorate, Chinese police have arrested another 39 people in connection with the scandal. Authorities last year also arrested 12 milk dealers and suppliers who allegedly sold contaminated milk to Sanlu, and six people were charged with selling melamine.

In late December, 17 people involved in producing, selling, buying and adding melamine to raw milk went on trial. Tian Wenhua and three other Sanlu executives appeared in court in Shijiazhuang, charged with producing and selling fake or substandard milk contaminated with melamine. Tian pleaded guilty, and told the court during her 14-hour December 31 trial that she learned about the tainted milk complaints and problems with her company’s BeiBei milk powder from consumer complaints in mid-May.

She then apparently led a working team to handle the case, but her company did not stop producing and selling formula until about September 11. She also did not report to the Shijiazhuang city government until August 2.

The court also sentenced Zhang Yanzhang, 20, to the lesser penalty of life imprisonment. Yanzhang worked with Zhang Yujun, buying and reselling the protein powder. The convicts were deprived of their political rights for life.

Xue Jianzhong, owner of an industrial chemical shop, and Zhang Yanjun were punished with life imprisonment and 15 years jail sentence respectively. The court found them responsible for employment of workers to produce about 200 tons of the tainted infant milk formula, and selling supplies to Sanlu, earning more than one million yuan.

“From October 2007 to August 2008, Zhang Yujun produced 775.6 tons of ‘protein powder’ that contained the toxic chemical of melamine, and sold more than 600 tons of it with a total value of 6.83 million yuan [$998,000]. He sold 230 tons of the “protein powder” to Zhang Yanzhang, who will stay behind bars for the rest of his life under the same charge. Both Zhangs were ‘fully aware of the harm of melamine’ while they produced and sold the chemical, and should be charged for endangering the public security,” the Court ruled.

The local court also imposed jail sentences of between five years and 15 years upon three top Sanlu executives. Wang Yuliang and Hang Zhiqi, both former deputy general managers, and Wu Jusheng, a former raw milk department manager, were respectively sentenced to 15 years, eight years and five years imprisonment. In addition, the court directed Wang to pay multi-million dollar fines. In December, Wang Yuliang had appeared at the Shijiazhuang local court in a wheelchair, after what the Chinese state-controlled media said was a failed suicide attempt.

The judgment also states “the infant milk powder was then resold to private milk collectors in Shijiazhuang, Tangsan, Xingtai and Zhangjiakou in Hebei.” Some collectors added it to raw milk to elevate apparent protein levels, and the milk was then resold to Sanlu Group.

“The Chinese government authorities have been paying great attention to food safety and product quality,” Yu Jiang Yu, spokesperson for the Ministry of Foreign Affairs, said. “After the case broke out, the Chinese government strengthened rules and regulations and took a lot of other measures to strengthen regulations and monitor food safety,” she added.

In the People’s Republic of China, the intermediate people’s court is the second lowest local people’s court. Under the Organic Law of the People’s Courts of the People’s Republic of China, it has jurisdiction over important local cases in the first instance and hear appeal cases from the basic people’s court.

The 2008 Chinese milk scandal was a food safety incident in China involving milk and infant formula, and other food materials and components, which had been adulterated with melamine. In November 2008, the Chinese government reported an estimated 300,000 victims have suffered; six infants have died from kidney stones and other acute renal infections, while 860 babies were hospitalized.

Melamine is normally used to make plastics, fertilizer, coatings and laminates, wood adhesives, fabric coatings, ceiling tiles and flame retardants. It was added by the accused to infant milk powder, making it appear to have a higher protein content. In 2004, a watered-down milk resulted in 13 Chinese infant deaths from malnutrition.

The tainted milk scandal hit the headlines on 16 July, after sixteen babies in Gansu Province who had been fed on milk powder produced by Shijiazhuang-based Sanlu Group were diagnosed with kidney stones. Sanlu is 43% owned by New Zealand’s Fonterra. After the initial probe on Sanlu, government authorities confirmed the health problem existed to a lesser degree in products from 21 other companies, including Mengniu, Yili, and Yashili.

From August 2 to September 12 last year Sanlu produced 904 tonnes of melamine-tainted infant milk powder. It sold 813 tonnes of the fake or substandard products, making 47.5 million yuan ($13.25 million). In December, Xinhua reported that the Ministry of Health confirmed 290,000 victims, including 51,900 hospitalized. It further acknowledged reports of “11 suspected deaths from melamine contaminated milk powder from provinces, but officially confirmed 3 deaths.”

Sanlu Group which filed a bankruptcy petition, that was accepted by the Shijiazhuang Intermediate People’s Court last month, and the other 21 dairy companies, have proposed a 1.1 billion yuan ($160 million) compensation plan for court settlement. The court appointed receiver was granted six months to conclude the sale of Sanlu’s assets for distribution to creditors. The 22 dairy companies offered “families whose children died would receive 200,000 yuan ($29,000), while others would receive 30,000 yuan ($4,380) for serious cases of kidney stones and 2,000 yuan ($290) for less severe cases.”

Sanlu stopped production on September 12 amid huge debts estimated at 1.1 billion yuan. On December 19, the company borrowed 902 million yuan for medical and compensation payment to victims of the scandal. On January 16, Sanlu paid compensation of 200,000 yuan (29,247 U.S. dollars) to Yi Yongsheng and Jiao Hongfang, Gangu County villagers, the parents of the first baby who died.

“Children under three years old, who had drunk tainted milk and had disease symptoms could still come to local hospitals for check-ups, and would receive free treatment if diagnosed with stones in the urinary system,” said Mao Qun’an, spokesman of the Ministry of Health on Thursday, adding that “the nationwide screening for sickened children has basically come to an end.”

“As of Thursday, about 90% of families of 262,662 children who were sickened after drinking the melamine-contaminated milk products had signed compensation agreements with involved enterprises and accepted compensation,” the China Dairy Industry Association said Friday, without revealing, however, the amount of damages paid. The Association (CDIA) also created a fund for payment of the medical bills for the sickened babies until they reach the age of 18.

Chinese data shows that those parents who signed the state-backed compensation deal include the families of six children officially confirmed dead, and all but two of 891 made seriously ill, the report said. Families of 23,651 children made ill by melamine tainted milk, however, have not received the compensation offer, because of “wrong or untrue” registration details, said Xinhua.

Several Chinese parents, however, demanded higher levels of damages from the government. Zhao Lianhai announced Friday that he and three other parents were filing a petition to the Ministry of Health. The letter calls for “free medical care and follow-up services for all victims, reimbursement for treatment already paid for, and further research into the long-term health effects of melamine among other demands,” the petition duly signed by some 550 aggrieved parents and Zhao states.

“Children are the future of every family, and moreover, they are the future of this country. As consumers, we have been greatly damaged,” the petition alleged. Chinese investigators also confirmed the presence of melamine in nearly 70 milk products from more than 20 companies, quality control official Li Changjiang admitted.

In addition, a group of Chinese lawyers, led by administrator Lin Zheng, filed Tuesday a $5.2 million lawsuit with the Supreme People’s Court of the People’s Republic of China (under Chief Grand Justice Wang Shengjunin), in Beijing, on behalf of the families of 213 children’s families. The class-action product liability case against 22 dairy companies, include the largest case seeking $73,000 compensation for a dead child.

According to a statement to the Shanghai Stock Exchange Market Friday, China’s Inner Mongolia Yili Industrial Group Company, which has a domestic market share of milk powder at 8 percent, reported a net loss in 2008 because of the milk scandal. A Morgan Stanley report states the expected company’s 2008 loss at 2.3 billion yuan. The scandal also affected Yili’s domestic rivals China Mengniu Dairy Company Limited and the Bright Group. Mengniu suffered an expected net loss of 900 million yuan despite earnings in the first half of 2008, while the Bright Group posted a third quarter loss at 271 million yuan last year.

New Zealand dairy giant Fonterra, said Saturday it accepted the Chinese court’s guilty verdicts but alleged it had no knowledge of the criminal actions taken by those involved. “We accept the court’s findings but Fonterra supports the New Zealand Government’s position on the death penalty. We have been shocked and disturbed by the information that has come to hand as a result of the judicial process,” said Fonterra Chief Executive Andrew Ferrier.

“Fonterra deeply regrets the harm and pain this tragedy has caused so many Chinese families,” he added. “We certainly would never have approved of these actions. I am appalled that the four individuals deliberately released product containing melamine. These actions were never reported to the Sanlu Board and fundamentally go against the ethics and values of Fonterra,” Ferrier noted.

Fonterra, which controls more than 95 percent of New Zealand’s milk supply, is the nation’ biggest multinational business, its second-biggest foreign currency earner and accounts for more than 24 percent of the nation’s exports. Fonterra was legally responsible for informing Chinese health authorities of the tainted milk scandal in August, and by December it had written off its $200 million investment in Sanlu Group.

Amnesty International also strongly voiced its opposition to the imposition of capital punishment by the Chinese local court and raised concerns about New Zealand’s implication in the milk scandal. “The death penalty will not put right the immense suffering caused by these men. The death penalty is the ultimate, cruel and inhumane punishment and New Zealand must take a stand to prevent further abuses of human rights.” AI New Zealand chief executive Patrick Holmes said on Saturday.

“The New Zealand government does not condone the death sentence but we respect their right to take a very serious attitude to what was extremely serious offending,” said John Phillip Key, the 38th and current Prime Minister of New Zealand and leader of the National Party. He criticized Fonterra’s response Monday, saying, “Fonterra did not have control of the vertical production chain, in other words they were making the milk powder not the supply of the milk, so it was a difficult position and they did not know until quite late in the piece. Nevertheless they probably could front more for this sort of thing.”

Keith Locke, current New Zealand MP, and the opposition Green Party foreign affairs spokesman, who was first elected to parliament in 1999 called on the government and Fonterra to respond strongly against the Chinese verdict. “They show the harshness of the regime towards anyone who embarrasses it, whether they are real criminals, whistleblowers or dissenters,” he said. “Many Chinese knew the milk was being contaminated but said nothing for fear of repercussions from those in authority. Fonterra could not get any action from local officials when it first discovered the contamination. There was only movement, some time later, when the matter became public,” he noted.

Green Party explained “it is time Fonterra drops its overly cautious act.” The party, however, stressed the death penalty is not a answer to the problems which created the Chinese milk scandal. “The Green Party is totally opposed to the death penalty. We would like to see the government and, indeed, Fonterra, speaking out and urging the Chinese government to stop the death penalty,” said Green Party MP Sue Kedgley.

It has emerged that the 33 Chilean miners trapped underground after the mine they were working in collapsed could be brought to the surface in a shorter time than was initially feared. While officials publicly announced that the men would not be brought to the surface until Christmas, sources inside technical meetings have revealed that they could in fact be on the surface by early November. The news comes as families were allowed to speak by radio-telephone to their trapped loved ones on Sunday. Over the weekend, video images filmed by the miners emerged showing the miners playing dominoes at a table and singing the Chilean national anthem. The miners also used the camera to send video messages to their families on the surface, saying that they regularly broke into tears, but were feeling better having received food and water.

The grainy nightvision images, filmed on a high definition camcorder that was sent down a small shaft to the mine, show the men in good spirits, chanting “long live Chile, and long live the miners.” They are unshaven and stripped to the waist because of the heat underground, and are seen wearing white clinical trousers that have been designed to keep them dry. Giving a guided tour of the area they are occupying, Mario Sepúlveda, one of the miners, explains they have a “little cup to brush our teeth”, and a place where they pray each day. “We have everything organized,” he tells the camera. Gesturing to the table in the center of the room, he says that “we meet here every day. We plan, we have assemblies here every day so that all the decisions we make are based on the thoughts of all 33.” Another unidentified miner asks to rescuers, “get us out of here soon, please.” A thermometer is shown in the video, reading 29.5C (85F).

As the film continues, it becomes evident that the miners have stuck a poster of a topless woman on the wall. The miners appear shy, and one man puts his hand to his face, presumably dazzled by the light mounted on the cameraman’s helmet. One miner sent a message to his family. “Be calm”, he says. “We’re going to get out of here. And we thank you from the bottom of our hearts for your efforts.” Another said that the miners are “sure that there are people here in Chile that are big people, that are powerful people, that are intelligent people, and they have the technology and they will all work together to get us out of here.” Speaking to the camera, one says: “we have had the great fortune that trapped in this mine there are good, professional people. We have electricians, we have mechanics, we have machine operators and we will let you know that while you are working to rescue us on the surface, we are down here ready to help you too.” It has been reported that Mario Gómez, 63, has become the group’s “spiritual leader”, having worked in the mines for over fifty years. He has requested that materials to build a shrine be sent down to the cavern.

Upon seeing the video in a private screening, family members, who are living in a small village of tents at the entrance to the San José copper-gold mine—which they have named Camp Hope—were elated. “He’s skinny, bearded and it was painful to see him with his head hanging down, but I am so happy to see him alive”, said Ruth Contreras, the mother of Carlos Bravo, who is trapped in the mine. The video, of which only a small portion has been released to the public, shows the miners, many of them wearing helmets, cracking jokes and thanking the rescuers for their continued efforts. The supplies are being sent to the men through a small shaft only twelve centimeters wide, and a laboratory has been set up with the purpose of designing collapsible cots and miniature sandwiches, which can be sent down such a narrow space.

CNN reported on Friday that “officials are splitting the men into two shifts so one group sleeps while the other works or has leisure time .. On average, each man has lost 22 pounds (10 kilograms) since they became trapped three weeks ago, and dehydration remains a threat. But a survey of the men indicates that at least nine miners are still too overweight to fit through the proposed rescue shaft. Initially, the miners survived by draining water from a water-cooled piece of equipment. To stay hydrated in the 90-degree mine, each miner must drink eight or nine pints of water per day.”

But while there are jubilant celebrations on the surface that the miners are alive, officials are now nervous that the miners could become depressed, trapped in a dark room the size of a small apartment. Chilean health minister Jaime Mañalich said that, on the video, he saw the telltale signs of depression. “They are more isolated, they don’t want to be on the screen, they are not eating well”, he said. “I would say depression is the correct word.” He said that doctors who had watched the video had observed the men suffering from “severe dermatological problems.” Dr. Rodrigo Figueroa, head of the trauma, stress and disaster unit at the Catholic University in Santiago, Chile, explained that “following the euphoria of being discovered, the normal psychological reaction would be for the men to collapse in a combination of fatigue and stress … People who are trained for emergencies – like these miners – tend to minimize their own needs or to ignore them. When it is time to ask for help, they don’t.” NASA has advised emergency workers that entertaining the miners would be a good idea. They are to be sent a television system complete with taped football matches. Another dilemma facing Mañalich is whether the miners should be permitted to smoke underground. While nicotine gum has been delivered to the miners, sending down cigarettes is a plan that has not been ruled out.

With the news that drilling of the main rescue tunnel was expected to begin on Monday, officials have informed the media that they hope to have the miners out of the mine by Christmas—but sources with access to technical meetings have suggested that the miners could actually be rescued by the first week of November. A news report described the rescue plan—”the main focus is a machine that bores straight down to 688m and creates a chimney-type duct that could be used to haul the miners out one by one in a rescue basket. A second drilling operation will attempt to intercept a mining tunnel at a depth of roughly 350m. The miners would then have to make their way through several miles of dark, muddy tunnels and meet the rescue drill at roughly the halfway point of their current depth of 688m.” Iván Viveros Aranas, a Chilean policeman working at Camp Hope, told reporters that Chile “has shown a unity regardless of religion or social class. You see people arriving here just to volunteer, they have no relation at all to these families.”

But over the weekend, The New York Times reported that the “miners who have astonished the world with their discipline a half-mile underground will have to aid their own escape — clearing 3,000 to 4,000 tons of rock that will fall as the rescue hole is drilled, the engineer in charge of drilling said Sunday … The work will require about a half-dozen men working in shifts 24 hours a day.” Andrés Sougarret, a senior engineer involved in operating the drill said that “the miners are going to have to take out all that material as it falls.”

The families of those trapped were allowed to speak to them by radio-telephone on Sunday—a possibility that brought reassurance both the miners and those on the surface. The Intendant of the Atacama Region, Ximena Matas, said that there had been “moments of great emotion.” She continued to say that the families “listened with great interest and they both felt and realized that the men are well. This has been a very important moment, which no doubt strengthens their [the miners’] morale.” The phone line is thought to be quite temperamental, but it is hoped that soon, those in the mine and those in Camp Hope will be able to talk every day. “To hear his voice was a balm to my heart … He is aware that the rescue is not going to happen today, that it will take some time. He asked us to stay calm as everything is going to be OK … He sounded relaxed and since it was so short I didn’t manage to ask anything. Twenty seconds was nothing”, said said Jessica Cortés, who spoke to her husband Víctor Zamora, who was not even a miner, but a vehicle mechanic. “He went in that day because a vehicle had broken down inside the mine … At first they told us he had been crushed [to death].”

Esteban Rojas sent up a letter from inside the mine, proposing to his long-time partner Jessica Yáñez, 43. While they have officially been married for 25 years, their wedding was a civil service—but Rojas has now promised to have a church ceremony which is customary in Chile. “Please keep praying that we get out of this alive. And when I do get out, we will buy a dress and get married,” the letter read. Yáñez told a newspaper that she thought he was never going to ask her. “We have talked about it before, but he never asked me … He knows that however long it takes, I’ll wait for him, because with him I’ve been through good and bad.”

Former US Representative Dan Rostenkowski died of lung cancer Wednesday at his vacation home in Genoa City, Wisconsin. Rostenkowski, whose political career ended in the early 1990s after he was convicted on fraud charges, was 82.

Rostenkowski’s death was confirmed by his spokesperson, Jim Jaffe, who said that the former congressman had been receiving treatment for lung cancer for a while. Rostenkowski had previously been treated for prostate cancer in the 1990s.

Rostenkowski was born on January 2, 1928 in Chicago, Illinois. He was an athlete and declined an invitation to try out for the Philadelphia Athletics (now the Oakland Athletics) in order to pursue a career in politics. Rostenkowski attended St. John’s Northwestern Military Academy in Wisconsin, served with the US Army in Korea, and graduated from Loyola University in 1951.

Rostenkowski’s political career was supported by the Cook County political machine, and he became a member of the Illinois state legislature in 1952, one year after graduating from college. In 1958, when he was 30, Rostenkowski was elected to the US House of Representatives. In 1961, he began serving on the United States House Committee on Ways and Means, the chief committee of the House for writing taxes. From 1981–1994, he served as the committee’s chairman. Rostenkowski was involved in the creation of Medicare in 1966 and he helped make amendments to the Social Security system in 1983.

In 1992, a federal jury began an inquiry into the House post office, and Rostenkowski was accused of buying US$22,000 in stamps with government funds and then turning them into cash. The investigation, which lasted two years, led to Republican allegations of corruption within the Democratic party. In 1994, Rostenkowski was charged with 17 felony counts, including the use of federal money to purchase furniture, and obstruction of justice. In order to avoid a trial, Rostenkowski made a deal with prosecutors, pleading guilty to two counts of mail fraud in exchange for fifteen months in prison, two months in a halfway house, and a US$100,000 fine.

Rostenkowski, who was not reelected for a nineteenth term in Congress in 1994, continued to maintain his innocence, and was pardoned by US President Bill Clinton in 2000.

The implosion of a relationship between Wikipedia founder Jimmy Wales and journalist Rachel Marsden has resulted in controversy and international headlines. Associated Press and ABC News have also reported on questionable activity by Wales involving Wikimedia Foundation expenses. The Wikimedia Foundation is a donor-supported non-profit organization which runs Wikipedia.

Marsden had contacted Wales two years ago about concerns she had over the article about her on Wikipedia, and Wales determined the article was not compliant with Wikipedia’s standards. The tech blog Valleywag revealed Wales had a personal relationship with Marsden, and posted supposed transcripts of their instant message conversations on its site, www.valleywag.com. Wales and Marsden met in February, and The Times reported that “An apparent transcript of their conversations before that meeting suggests that, although Mr Wales had withdrawn from the editing process, he was still influencing the editors.” The Times quoted Wales from the chat logs as having stated to Marsden “The truth is of course a much worse conflict of interest than that; but that will do.” — in reference to his conflict of interest regarding Marsden’s article on Wikipedia.

Wales posted a public statement on Saturday on Wikipedia addressing the matter, and stated that his relationship with Marsden was over: “First, while I find it hard to imagine that anyone really cares about my sex life, the facts are: I am separated from my wife. I considered myself single at the time of my one meeting with Rachel Marsden on Feb. 9, 2008 … I am no longer involved with Rachel Marsden. Gossipy stories suggesting that I have been in a relationship with her ‘since last fall’ are completely false … I care deeply about the integrity of Wikipedia, and take very seriously my responsibilities as a member of the board and as a member of the Wikipedia community. I would never knowingly do anything to compromise that trust.” With regard to the conflict of interest in Marsden’s article, Wales had acknowledged to a team of Wikipedia editors in February 2008 that he and Marsden “became friends … and that we would be meeting about that,” and stated “I recused myself from any further official action with respect to her biography.”

On Sunday, The Canadian Press reported that Marsden had posted photos of herself on Ebay, and was selling items that Wales had left at her New York City apartment. In her Ebay posting, Marsden stated: “Hi, my name is Rachel and my (now ex-) boyfriend, Wikipedia founder Jimmy Wales, just broke up with me via an announcement on Wikipedia … It was such a classy move that I was inspired to do something equally classy myself, so I’m selling a couple of items of clothing he left behind, here in my NYC apartment, on eBay. Jimbo was supposed to come visit me in a couple of weeks and pick up some of his stuff, but obviously that won’t be happening now.” Marsden told The Canadian Press “It didn’t really help matters that Jimmy chose to announce the breakup to the entire world via Wikipedia (which apparently now is an online encyclopedia that doubles as a personal soapbox?) rather than to me directly (which he did much later, in an instant message discussion).”

Marsden placed a t-shirt and sweater which she said were left at her apartment by Wales up on Ebay, and started the bidding for each at ninety-nine cents, with the auctions set to end on March 12. By Monday, bidding on the t-shirt had reached US$300, and by Tuesday the highest bid had reached $12,200. In an email to The Globe and Mail, Marsden stated “My only focus right now, to be really honest, is on my career and finding a way to get back into print, TV, or radio here in NYC,” she wrote. “All of this other personal stuff is just an unfortunate distraction.”

Jay Walsh, the Wikimedia Foundation’s head of communications, told the San Jose Mercury News that Wales’ actions in relaying Marsden’s concerns about her Wikipedia article to a team of trusted editors was within his “routine” role. When asked by the San Jose Mercury News if Wales’ actions regarding the Marsden article could compromise his role with the Wikimedia Foundation and Wikipedia, Walsh responded “No, absolutely not.”

On Tuesday, ABC News carried a story by Wired News reporter Megan McCarthy regarding allegations of “excessive spending” by Wales, and Associated Press also reported on questions involving Wikimedia Foundation expenses. McCarthy reported that former Wikimedia executive Danny Wool, who had left the foundation last year, criticized Wales’ use of Wikimedia Foundation expenses in a blog post. Wool stated that Wales had tried to expense $300 bottles of wine, a $1,300 dinner for four at a Florida steakhouse, and visits to Moscow massage parlors to the foundation, and that the foundation rescinded Wales’ corporate credit card in 2006. Wool also stated that Wales paid the foundation $7,000, after being short $30,000 on receipts for expenses.

Wool told EPICENTER that “There were occasions where he used [the Wikimedia Foundation] for personal advancement under the guide [sic] of the mission. And, as someone who was in there for the mission part of it, I found that rather distressful.” Wool commented in an interview with the San Francisco Chronicle: “Originally, it was carelessness … But as things developed, it became more apparent and obvious that he was taking advantage of the foundation credit card. It was almost like his personal piggy bank.”

In an instant message exchange with Associated Press, Wales denied that the Wikimedia Foundation had taken away his corporate credit card, and asserted that he had made the decision to stop expensing business travel for the foundation. Wales highlighted a statement by the foundation’s executive director Sue Gardner: “Jimmy has never used Wikimedia money to subsidize his personal expenditures. Indeed, he has consistently put the foundation’s interests ahead of his own.” In an email to Associated Press, Brad Patrick, a former attorney for the Wikimedia Foundation, stated “Danny seems interested in blogging his way straight to a lawsuit”.

Florence Devouard, who chairs the Wikimedia Foundation, told Associated Press that Wales had been “slow in submitting receipts,” and that the foundation had rejected Wales’ expense at the Florida steakhouse. Devouard told fellow foundation board members in a private email that she had convinced Associated Press that “the money story was a no story,” and told Wales “I find (it) tiring to see how you are constantly trying to rewrite the past. Get a grip!” Wales told Associated Press: “The board, the current executive director, the previous executive director, and independent auditors have reviewed our books and publicly agree that all of my expenses were appropriate and fully accounted for.”

Media reports speculated on how the controversy would end up being represented in Wikipedia itself. On Wednesday, the St. Petersburg Times wrote: “Wales’ Wikipedia page said only this about Marsden: ‘Wales had a brief relationship with Canadian journalist Rachel Marsden.'” An article in The Australian surmised: “History will decide whether Mr Wales broke his own principles, but before that happens there may well be a Wikipedia page devoted to the controversy.”

Satire site Uncyclopedia, a parody of online encyclopedia Wikipedia, has been labeled by the Malaysian government as dangerous. The Internal Security Department of Malaysia issued the warning today, saying that the site has “messages and information insulting Malaysia”.

The warning notes the creation date of the website as being 5 January 2005, and hosted by Wikia, Inc., both of which are correct. However, it claims Wikia owns Wikipedia; Wikipedia is a charitable non-profit website owned by the non-profit Wikimedia Foundation, while Wikia is an independent, for-profit company.

The report evidently mentions that Uncyclopedia covers Malaysian “history, culture, the political leaders, the government, the national song and the name / history of the national flag,” none of which is “correct”. They accuse the website of helping to reinforce a bad international image of their country.

There are no reports of the site being blocked from access within the country, only this statement, which urges Malaysians not to circulate the content.

Uncyclopedia’s article on Malaysia begins:

The site has fired back with a parody article posted at the site under their UnNews section, titled Uncyclopedia Internal Security Department warns on Malaysia. The article suggests that the “Internal Security Department of the Uncyclomedia Foundation,” which is a facetious and fictitious parent organization of Uncyclopedia, identifies Malaysia “as a dangerous country… It warned its people not to use the country today.”

There are forty-seven individual language editions of Uncyclopedia, including Tolololpedia, which is written in Bahasa Melayu, the Malay language. This is in addition to fictional “language” editions which include Oscar Wilde, Newspeak, N00b, White Supremacist, and Re: PharmaccgRy.

A new historic physics record has been set by scientists for exceedingly small writing, opening a new door to computing‘s future. Stanford University physicists have claimed to have written the letters “SU” at sub-atomic size.

Graduate students Christopher Moon, Laila Mattos, Brian Foster and Gabriel Zeltzer, under the direction of assistant professor of physics Hari Manoharan, have produced the world’s smallest lettering, which is approximately 1.5 nanometres tall, using a molecular projector, called Scanning Tunneling Microscope (STM) to push individual carbon monoxide molecules on a copper or silver sheet surface, based on interference of electron energy states.

A nanometre (Greek: ?????, nanos, dwarf; ?????, metr?, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., 10^-9 m or one millionth of a millimetre), and also equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of nanotechnology.

“We miniaturised their size so drastically that we ended up with the smallest writing in history,” said Manoharan. “S” and “U,” the two letters in honor of their employer have been reduced so tiny in nanoimprint that if used to print out 32 volumes of an Encyclopedia, 2,000 times, the contents would easily fit on a pinhead.

In the world of downsizing, nanoscribes Manoharan and Moon have proven that information, if reduced in size smaller than an atom, can be stored in more compact form than previously thought. In computing jargon, small sizing results to greater speed and better computer data storage.

“Writing really small has a long history. We wondered: What are the limits? How far can you go? Because materials are made of atoms, it was always believed that if you continue scaling down, you’d end up at that fundamental limit. You’d hit a wall,” said Manoharan.

In writing the letters, the Stanford team utilized an electron‘s unique feature of “pinball table for electrons” — its ability to bounce between different quantum states. In the vibration-proof basement lab of Stanford’s Varian Physics Building, the physicists used a Scanning tunneling microscope in encoding the “S” and “U” within the patterns formed by the electron’s activity, called wave function, arranging carbon monoxide molecules in a very specific pattern on a copper or silver sheet surface.

“Imagine [the copper as] a very shallow pool of water into which we put some rocks [the carbon monoxide molecules]. The water waves scatter and interfere off the rocks, making well defined standing wave patterns,” Manoharan noted. If the “rocks” are placed just right, then the shapes of the waves will form any letters in the alphabet, the researchers said. They used the quantum properties of electrons, rather than photons, as their source of illumination.

According to the study, the atoms were ordered in a circular fashion, with a hole in the middle. A flow of electrons was thereafter fired at the copper support, which resulted into a ripple effect in between the existing atoms. These were pushed aside, and a holographic projection of the letters “SU” became visible in the space between them. “What we did is show that the atom is not the limit — that you can go below that,” Manoharan said.

“It’s difficult to properly express the size of their stacked S and U, but the equivalent would be 0.3 nanometres. This is sufficiently small that you could copy out the Encyclopaedia Britannica on the head of a pin not just once, but thousands of times over,” Manoharan and his nanohologram collaborator Christopher Moon explained.

The team has also shown the salient features of the holographic principle, a property of quantum gravity theories which resolves the black hole information paradox within string theory. They stacked “S” and the “U” – two layers, or pages, of information — within the hologram.

The team stressed their discovery was concentrating electrons in space, in essence, a wire, hoping such a structure could be used to wire together a super-fast quantum computer in the future. In essence, “these electron patterns can act as holograms, that pack information into subatomic spaces, which could one day lead to unlimited information storage,” the study states.

The “Conclusion” of the Stanford article goes as follows:

The team is not the first to design or print small letters, as attempts have been made since as early as 1960. In December 1959, Nobel Prize-winning physicist Richard Feynman, who delivered his now-legendary lecture entitled “There’s Plenty of Room at the Bottom,” promised new opportunities for those who “thought small.”

Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model).

Feynman offered two challenges at the annual meeting of the American Physical Society, held that year in Caltech, offering a $1000 prize to the first person to solve each of them. Both challenges involved nanotechnology, and the first prize was won by William McLellan, who solved the first. The first problem required someone to build a working electric motor that would fit inside a cube ¹/₆₄ inches on each side. McLellan achieved this feat by November 1960 with his 250-microgram 2000-rpm motor consisting of 13 separate parts.

In 1985, the prize for the second challenge was claimed by Stanford Tom Newman, who, working with electrical engineering professor Fabian Pease, used electron lithography. He wrote or engraved the first page of Charles Dickens’ A Tale of Two Cities, at the required scale, on the head of a pin, with a beam of electrons. The main problem he had before he could claim the prize was finding the text after he had written it; the head of the pin was a huge empty space compared with the text inscribed on it. Such small print could only be read with an electron microscope.

In 1989, however, Stanford lost its record, when Donald Eigler and Erhard Schweizer, scientists at IBM’s Almaden Research Center in San Jose were the first to position or manipulate 35 individual atoms of xenon one at a time to form the letters I, B and M using a STM. The atoms were pushed on the surface of the nickel to create letters 5nm tall.

In 1991, Japanese researchers managed to chisel 1.5 nm-tall characters onto a molybdenum disulphide crystal, using the same STM method. Hitachi, at that time, set the record for the smallest microscopic calligraphy ever designed. The Stanford effort failed to surpass the feat, but it, however, introduced a novel technique. Having equaled Hitachi’s record, the Stanford team went a step further. They used a holographic variation on the IBM technique, for instead of fixing the letters onto a support, the new method created them holographically.

In the scientific breakthrough, the Stanford team has now claimed they have written the smallest letters ever – assembled from subatomic-sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The new super-mini letters created are 40 times smaller than the original effort and more than four times smaller than the IBM initials, states the paper Quantum holographic encoding in a two-dimensional electron gas, published online in the journal Nature Nanotechnology. The new sub-atomic size letters are around a third of the size of the atomic ones created by Eigler and Schweizer at IBM.

A subatomic particle is an elementary or composite particle smaller than an atom. Particle physics and nuclear physics are concerned with the study of these particles, their interactions, and non-atomic matter. Subatomic particles include the atomic constituents electrons, protons, and neutrons. Protons and neutrons are composite particles, consisting of quarks.

“Everyone can look around and see the growing amount of information we deal with on a daily basis. All that knowledge is out there. For society to move forward, we need a better way to process it, and store it more densely,” Manoharan said. “Although these projections are stable — they’ll last as long as none of the carbon dioxide molecules move — this technique is unlikely to revolutionize storage, as it’s currently a bit too challenging to determine and create the appropriate pattern of molecules to create a desired hologram,” the authors cautioned. Nevertheless, they suggest that “the practical limits of both the technique and the data density it enables merit further research.”

In 2000, it was Hari Manoharan, Christopher Lutz and Donald Eigler who first experimentally observed quantum mirage at the IBM Almaden Research Center in San Jose, California. In physics, a quantum mirage is a peculiar result in quantum chaos. Their study in a paper published in Nature, states they demonstrated that the Kondo resonance signature of a magnetic adatom located at one focus of an elliptically shaped quantum corral could be projected to, and made large at the other focus of the corral.
