A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

A bomb exploded early on Tuesday morning in Londonderry, Northern Ireland, injuring two police officers. Investigations into the identity of the bombers and their motive are continuing. The Real Irish Republican Army a paramilitary group that aims to bring about a united Ireland, has claimed responsibility.

The explosion on Culmore Road caused serious damage to nearby buildings, including Da Vinci’s hotel and a branch of the Ulster Bank. A telephone warning was given an hour beforehand and the area, including the hotel, was cleared. The officers, standing near the edge of the exclusion zone, suffered injuries to their necks and ears when they were blown over by the blast.

Chief Superintendent Stephen Martin from the Police Service of Northern Ireland asked for anyone who had seen the Vauxhall Corsa car in which the bomb was hidden before the explosion to come forward. Although the bomb, thought to be over 200lb, was left near the bank, Mr Martin did not think it was the intended target and said that the bomb may have been left because of the presence of police in the area.

The Deputy First Minister of Northern Ireland, Martin McGuinness, called the bombers “Neanderthals” and “conflict junkies”, and added that they were “failing miserably” to destroy the peace process in Northern Ireland. He is attending the Conservative Party conference in Birmingham; the Daily Mail reports he refused to comment on if the attack was to coincide with his absence. The city’s mayor, Colm Eastwood, who was at the scene, said he was “disgusted”, adding “I do not know what these people are hoping to achieve. They say they love their country but they spend time trying to destroy it.”

The National Archives of Australia have, as part of their standarddocument release cycle, released thirty year old documents from theWhitlam government.

The centre piece of the 1974 archives are a series of documents fromthe Australian Cabinet and the Treasury pertaining to the attempt toobtain a $US4 billion loan by the Whitlam government from the MiddleEast. The obtaining of these loans and the scandal generated becamecollectively known as the “Loans Affair,” and contributedsignificantly towards the dismissal of the Whitlam government by SirJohn Kerr the following year.

The documents from Treasury, which include descriptions of both theloan itself and the people involved in arranging them, are scathing.The “Points that might be made” document of December 13, 1974 clearlystates that Treasury believed the distinct possibility that the loansmight be part of “a confidence trick of major proportions”. Minutesfrom another meeting five days later state the “incredulity” on thepart of the Bank of England and the Federal Reserve Bank of New Yorkregarding the viability of the loan.

Those documents now available comprise the beginning of the LoansAffair, from the initial offers to the end of 1974. The remainder ofthe Loans Affair documents, as well as everything else from 1975 willbe released on January 1, 2006.

Wikinews reporter Iain Macdonald has performed an interview with Dr Isabella Margara, a London-based member of the Communist Party of Greece (KKE). In the interview Margara sets out the communist response to current events in Greece as well as discussing the viability of a communist economy for the nation. She also hit back at Petros Tzomakas, a member of another Greek far-left party which criticised KKE in a previous interview.

The interview comes amid tensions in cash-strapped Greece, where the government is introducing controversial austerity measures to try to ease the nation’s debt-problem. An international rescue package has been prepared by European Union member states and the International Monetary Fund – should Greece require a bailout; protests have been held against government attempts to manage the economic situation.

Adriaan Vlok, the former South African apartheid regime’s police minister, went to Reverend and director-general Frank Chikane’s church in Soweto on Sunday, the 3rd of September to repent. This follows his recent apology on the 3rd of August, 2006, which was described by some as “a miracle” that has had global impact.

Toyota has been accused by a U.S. House of Representatives committee with misleading the public and investigators over its recent recalls.

The accusations, in a statement from the House Energy and Commerce Committee, claim that Toyota both relied on a flawed study in its assessment of the issue of sticking accelerator pedals at the heart of the recalls, and then made misleading statements about its response. According to the authors of the letter, Henry Waxman and Bart Stupak, Toyota dismissed, rather than investigated, the idea that the cars’ computers were at fault. In a statement, James Lentz, the president of Toyota’s American division, claimed that hardware issues were to blame, and that dealers were repairing the faulty part. Toyota also released a study commissioned from the research firm Exponent that said electronic systems were not to blame.

According to the House committee, however, the study involved only six vehicles, none of which had problems with their electrical systems, and was insufficient to produce an accurate result. “Our preliminary assessment is that Toyota resisted the possibility that electronic defects could cause safety concerns, relied on a flawed engineering report and made misleading public statements concerning the adequacy of recent recalls to address the risk of sudden unintended acceleration.”

The company is under a criminal investigation, and has received two subpoenas for documents from two House committees relating to the recalls, although whether they are directly related to the letter is unclear. The documents are related to accelerator issues in several models, as well as brake problems with the Prius hybrid car, and were served earlier in in February by a federal grand jury and the Securities and Exchange Commission. Toyota has released upwards of 75,000 pages of documents under the requests.

In a separate, though related, development, it has emerged that Toyota last year negotiated a limited recall for two models, the Toyota Camry and Lexus ES, that were affected by the accelerator recalls, saving the company an estimated $100 million. A confidential internal presentation in July 2009 made the claim, and a month later, a Lexus ES, one of the models under the limited recall crashed in California, killing four people. The claims apparently referenced a September, 2007 recall of floor mats that could trap gas pedals, the same problem that triggered a full recall of numerous Toyota cars to fix the same problem. In the same presentation, the company claimed to have avoided recalls of another model related to rust, as well as delaying new federal safety regulations.
