Standard & Poor’s downgraded Egypt’s currency rating for the second time in four months based on the country’s shorfall in foreign reserves and shaky political transition. It’s the latest development for a nation facing mounting economic diffuclties.

Egypt’s foreign reserves fell by over 50 percent last year to about US$16 billion. Egypt has requested US$3.2 billion from the International Monetary Fund to bolster its reserves and prevent a devalation but that could take months.

Experts say that Egypt’s problem of attracting foreign investment and tourists, which are two sources that would increase reserves, has already caused the Egyptian pound to lose 1 percent of its value and if the country doesn’t solve the shortfall in foriegn currency, it could even lead to a further currency devaluation within the next two to three months.

The long-term solution is to restore tourism and foreign investments but both are suffering because of the continuing unrest.

Qatari non-profit organization Gulf Organization for Research and Development (GORD) launched a low emissions car at the 2012 United Nations Climate Change Conference (COP 18) in Doha. The car was designed and developed in Qatar.

Revealed during a press conference at the Qatar National Convention Centre, the car in addition to an internal combustion engine, includes an automotive thermoelectric generator designed to capture waste heat to produce hydrogen. GORD expects the heat waste collecting system to be compatible with any gasoline or compressed natural gas car.

GORD chairman Dr Al-Horr summarised the key concepts of the invention in a statement saying, “Our car produces electricity at no cost by capturing thermal waste energy, reducing costs and eliminating the need for an external source of electricity. Also, bulky compressed-hydrogen cylinders are a thing of the past, as our concept accomplishes the production of hydrogen by using water through fuel cells integrated within the car.”

Most of the energy in Qatari vehicle comes from the the car’s gasoline tank, supplemented by a thin film photo-voltaic panel on the roof. Normally in a combustion engine, chemical energy stored in a fuel, such as gasoline, is converted into heat energy through combustion. This heat energy is then converted into mechanical energy, manifested as an increase in pressure in the combustion chamber due to the kinetic energy of the combustion gases. The kinetic energy of these combustion gases are then converted into work; because of the inefficiencies in converting chemical energy into useful work, internal combustion engines have a theoretical maximum effiecincy of 37% (with what is achievable in day to day applications being about half of this). Of the chemical energy in the consumed fuel used by an internal combustion engine 40% is dissipated as waste heat. However, the Qatari vehicle uses a thermoelectric generator to convert this waste heat into electricity. Such generators are used in space vehicles, and produce electricity when thermoelectric materials are subjected to a temperature gradient, the greater the gradient the greater the amount of electrcity produced. In the GORD vehicle the electricity produced is used to electrolyse potable water to produce hydrogen which can be introduced into the vehicle’s existing fuel system.

The researchers showed that the heat waste collection engine caused a decrease in the car’s emissions, including a decrease of carbon monoxide and nitrous oxide emissions by more than 50%, the fuel efficiency increasing by 20%. On its website, GORD said that the heat waste collector engine is universal, “Any car can be adapted to accommodate the system as it doesn’t alter any electro-mechanical systems”.

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.

Several reports indicate that the ousted fugitive ex-Prime Minister of Thailand, Thaksin Shinawatra, is to again become involved in the country’s politics. He is scheduled to give another phone-in address from abroad on December 14 to supporters at the national Suphachalasai Stadium.

People’s Power Party (PPP) MP, and spokesman for the pro-government “Truth Today” roadshow Jatuporn Promphan said, “Thaksin will no longer wait to be attacked, he will fight back by all means, particularly with an eye-for-an-eye strategy, from now on. Thaksin now believes that the only way for him to survive and to live is to fight for his name”.

Currently in exile and facing a two year jail term should he return to Thailand, Thaksin informed lawyers from his current residence in Dubai that he would not appeal the conviction for corruption in the Ratchadapisek land deal. While lawyers claim to have prepared the needed paperwork to challenge the conviction, the deadline to do so is today.

According to the Bangkok Post, a return to politics by the ex-PM has caused some concern among PPP government members over the divisions this could cause within the country. Thaksin still enjoys a great deal of support from the rural poor in the country’s North-East where the populist policies of his now-outlawed Thai Rak Thai (TRT) party helped win a majority. His most vocal critics, the People’s Alliance for Democracy (PAD) have now occupied Government House in Bangkok for over three months.

The close association of the ruling PPP with the former premier has given them their own set of problems. The party is actively contesting a case in the country’s supreme court that could see it dissolved. The case centres around allegations of vote buying and the party’s former deputy leader, Yongyuth Tiyapairat, stands accused of paying village heads for votes. The PPP disputes that this was a party action as opposed to the independent actions of Yongyuth and the other accused. A ruling on the fraud from last December’s election is expected soon.

Critics of the government claim that it is simply a front for the ex-PM and his dissolved party. The yellow-shirted PAD protesters at Government House assert that current Prime Minister, Somchai Wongsawat, Thaksin’s brother-in-law, is merely a proxy for the controversial ex-leader.

Prosecution of Thaksin on other charges, which he maintains are politically motivated, continues; the supreme court is expected to hold a hearing next month on accusations that he is ‘unusually rich’. This relates to the sale of the family’s stake in Shin Corporation to Temasek Holdings, the investment arm of the Singapore government. Assets worth 76 billion baht (US$ 2.2 billion) are currently frozen over this issue. The ex-PM escaped impeachment over the tax-free sale of Shin in February 2006. Thai media reports that an amicable divorce of Thaksin and his wife Pojaman in Hong Kong will have no bearing on the case or asset seizure. Despite the split last week neither can return to Thailand without facing imprisonment; Potjam was earlier successfully prosecuted and given a three year sentence.

The San Francisco Museum of Modern Art (SFMOMA) has purchased the painting Intermission, by American artist Edward Hopper. The piece, created in 1963, is one of the last paintings created by Hopper.

Hopper’s realist style, which visually examined American urban and rural life in the first half of the 20th century, made him one of the most influential and important American artists of the modern era. The painting, which was sold by a private collector, is believed to be valued at over $25 million.

Intermission shows a woman sitting alone in the front row of a theater. The theater is empty, and is described, by San Francisco Chronicle art critic Kenneth Baker as expressing emotion and social isolation, a standard theme in Hopper’s works. The inspiration for the painting came to Hopper while he was watching a film.

Hopper’s wife, Josephine, had scheduled Hopper to create the painting in a theater, however Hopper would complete the painting at his studio in New York City. Original sketches of Intermission show a second person sitting in the third row — a figure that never made it into the final painting. Baker calls Intermission a “prime example of Hopper’s austere realist vision”.

SFMOMA will not disclose how much they paid for Intermission. When the painting Hotel Window, which is of similar size and from the same period, sold at auction in 2006, it sold for $26.9 million. It is believed that “Inspiration” is worth just as much, if not more. Intermission was purchased with the help of donor funds, and acquired through the San Francisco-based Fraenkel Gallery, which sold if on behalf of a private collector.

In exchange for the acquisition of Intermission, SFMOMA is selling another Hopper painting: Bridal Path, from 1939. A lesser known work of Hopper’s, Bridal Path shows a horseback riding path in Central Park. By selling Bridal Path, SFMOMA is able to help fund the acquisition of the more well known Intermission. This practice is slowly gaining popularity within a museum and art market that previously disapproved of the sale of lesser known works for more popular acquisitions. Baker acknowledges the past practices, but believes that this is “a necessary practice in an art market where prices for historically important art continue to rise steeply.”

Intermission goes on display for the public on Friday, at SFMOMA.

Tom Cruise: An Unauthorized Biography, a biography of actor Tom Cruise written by journalist Andrew Morton, was released in the United States yesterday amidst the potential for a US$100 million lawsuit against its publisher, St. Martin’s Press. The book will not be published in Australia, Britain, and New Zealand due to strict libel laws in those countries. Morton had previously written the biography of Diana, Princess of Wales, Diana: Her True Story. The book has reached number nine on Amazon.com‘s list of top sellers.

The book describes Cruise as the No. 2 leader of the Church of Scientology, blames Scientologists for the breakup of Cruise and actress Nicole Kidman, and states that Cruise’s latest mission is to recruit David Beckham and wife Victoria into Scientology. The book also describes how some Scientology followers thought that Cruise’s wife Katie Holmes was impregnated with frozen sperm from L. Ron Hubbard, founder of Scientology, and Morton compares the situation to Rosemary’s Baby “In her more reflective moments, Katie might have felt as if she were in the middle of a real-life version of the horror movie ‘Rosemary’s Baby,’ in which an unsuspecting young woman is impregnated with the devil’s child.”

A 15-page statement released by the Church of Scientology denied Morton’s assertions of Cruise’s No. 2 standing within the organization. In the statement the Church of Scientology claims that Morton did not respond to requests for an interview “The Church of Scientology requested to be interviewed or be presented with any allegations so we could respond. Morton refused despite our insistence in offering our cooperation.” The Church of Scientology also specifically responded to the claims regarding Hubbard’s frozen sperm: “Was Katie impregnated by L. Ron Hubbard’s frozen sperm? … As distasteful as it is to have to say it, Mr. Hubbard’s sperm was never frozen.”

According to the AFP, “the Church of Scientology is reportedly considering legal action against US publishers St Martin’s Press.” The Church of Scientology’s general counsel, Eliot Abelson, discussed the potential for litigation in an interview with the Mail on Sunday “We are seriously considering legal action and will wait to see the public reaction.” Cruise’s attorney Bertram Fields expressed thanks for the strict libel laws in Britain “It’s not being published in England. The American publishers criticised the libel laws in Britain because they require an author to tell the truth. Well, thank God for the British libel laws.” New York’s Daily News has reported that the Church of Scientology and lawyers for Cruise are planning a US$100 million lawsuit over the book’s publication. Rogers & Cowan, the public relations agency that represents Cruise, issued a statement which criticized Morton for not interviewing “one person who has known or worked with Tom” in the past twenty-five years.

The Church of Scientology statement also pointed out that the book is not being published in Australia, Britain and New Zealand due to the countries’ strict libel laws. Australia-based companies Pan Macmillan Australia and retailer Dymocks Booksellers decided not to stock copies of the book on their shelves, due to fears of potential defamation actions against them. A spokesperson for Pan Macmillan Australia stated that they had not received threats from Cruise’s representatives or from Scientologists, but that their attorneys had advised them not to sell the book. Don Grover, chief executive for Dymocks Group stated after legal advice their company had decided to “play it safe” – though neither their lawyers or publishers had read the book itself. A representative of MacMillan stated that the book would not be published in New Zealand, but would make no further comment on the matter. A Dymocks New Zealand representative explained that it was possible that the book could be published by their company in New Zealand, but would have to look into it further “The US has different legislation than New Zealand and Australia. There are some issues with the book having legal questions asked and we would need those tidied up before we stock it.”

Morton spent two years doing research for the book, and spoke with individuals who knew Cruise personally, and executives within the Church of Scientology. Morton stated that some of these executives emailed him, confirming the accuracy of material within the book. Morton described the desire for anonymity by some of the sources in the book “Some people, obviously, will not go on the record to talk about Tom Cruise because they’re scared of him.”

In an interview on The Today Show with Meredith Vieira, Morton defended his work and responded to the statement from the Church of Scientology. Morton stated that it was unusual for a church to respond in such a way if Cruise is simply an ordinary member, asking “How many churches support one parishioner — a lowly parishioner — that way?” Morton described the response as an attack “Their policy is always to attack the attacker. Their tactic is to denigrate those who seek to talk about it.” He told Vieria that he had attempted to contact the head of the Church of Scientology, David Miscavige, but “They refused it. I formally asked for it. I was instructed to ask for it by the publisher’s attorneys, and so what they’re saying is nonsense.”

Morton explained his motivation for writing the book “He’s no longer just an actor or producer, but a powerful advocate for a cult that’s out to expand, especially in Europe.” Morton stated that his interest was piqued after Cruise jumped on Oprah’s couch during a May 23, 2005 appearance on The Oprah Winfrey Show, and got into a heated debate with Matt Lauer about his beliefs regarding psychiatry during a June 24, 2005 appearance on The Today Show.

200,000 litres of oil leaked into waters off the coast of Brisbane from the Pacific Adventurer when their fuel tanks were damaged in rough seas on Wednesday. The figure is about ten times higher than the original estimate of twenty thousand litres of oil. The devastating diesel oil spill has spread along 60 kilometres (37 miles) of the Queensland coast. In addition, 31 containers with 620 tonnes of ammonium nitrate fertiliser flew overboard during the violent storm.

Questions are being asked why the Hong Kong cargo ship was out in seas with nine meter waves caused by Cyclone Hamish, a Category 5 tropical cyclone, as well as why the fertiliser containers were not properly secured. One of the overboard containers ruptured the hull of the Pacific Adventurer, causing between 30 to 100 tonnes of oil to spew from the severely damaged ship.

If the ammonium nitrate mixes with the heavy oil, an explosion could occur. None of the containers have been recovered. Some of these may float, but it is believed that they may have sunk which then may cause algal blooms.

Disaster zones have been declared at Bribie and Moreton Islands, and along the Sunshine coast.

The vessel’s owner, Swire Shipping, reported that a second leak began on Friday, when the ship began listing after docking at Hamilton for repairs. “As full soundings of the vessel’s tanks were being taken at the port to determine how much oil had leaked from the vessel, a small quantity of fuel oil escaped from the Pacific Adventurer,” it stated. The ship was brought upright, and a recovery vessel was used to suck up the oil from the water. The leak produced a 500m-long oil slick down the Brisbane River. Booms were placed around this oil spill so that a skimmer could clean up the second spill.

Swire Shipping could face clean up costs of AU$100,000 a day as well as fines up to AU$1.5million (US$977,000; £703,000) if found guilty of environmental breaches or negligence.

Sunshine Coast beaches are slowly starting to be reopened. The beach of Mooloolaba was still closed following reports of burning sensations from swimmers. 12 beaches remain closed; however, 13 have been reopened.

Over 300 state government and council workers are using buckets, rakes and spades in the clean up effort. Sunshine Coast Mayor Bob Abbott says the majority will be gone by Sunday afternoon. The full environmental impact on wildlife is not yet known. One turtle and seven pelicans have been found covered in oil.

There are concerns that the drinking water of Moreton Island is at risk, as the island uses water from the underground water table near the oil spill site.

“Every bucketload of contaminated sand has to be removed from the island by barge, and each bucketload from a front-end loader weighs about one tonne. It’s just an impossible task,” said Mr Trevor Hassard of the Tangalooma Dolphin Education Centre.

The commercial fishing industry has suffered from the incident. Trawlers won’t resume operations until Sunday evening, and any catches will be tested for human consumption.

A 15-year-old boy, arrested last Friday in conjunction with criminal threats made on Wikipedia, was charged Thursday with seven felonies in Pomona Juvenile Court in Pomona, California. Prosecutors stated that the teen posted two threats on Wikipedia, saying that six named students as well as members of his school’s badminton team would be shot. The court arraignment had initially been set for Tuesday, but was continued until Thursday. Wikinews interviewed the Wikipedia administrator who contacted police after the threats had been made on the site.

Though officials had said the boy made a full confession that he had made threats to other students via the online encyclopedia Wikipedia, he denied the charges at the Thursday court petition. The court ordered that he remain detained pending a May 9 scheduled appearance before Pomona Juvenile Court. He has remained in custody since his arrest.

The threats were made via two separate edits to the Wikipedia article about Glen A. Wilson High School in Hacienda Heights, California on April 16. Wikipedia administrators were made aware of the threats in a post to the “Administrators’ noticeboard” on April 16 by Wikipedia admin Dreadstar. Another Wikipedia administrator, John Reaves, contacted the police in Los Angeles, California, and helped them work with the Internet service provider to find more information on the IP address that made the threat. A third Wikipedia administrator, Persian Poet Gal, removed the threats from the edit history of the article after finding out that the student had been arrested.

Students’ backpacks were searched prior to entering Glen A. Wilson High School on April 17 and all after-school activities were canceled that day. All classes were canceled April 18, and classes resumed on Monday.
