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.

The left wing of the Industrial Palace (Pr?myslový palác) – central building of the Prague Exhibition Grounds (Výstavišt?) in the capital city of Czech Republic was destroyed by fire yesterday night. The fire began at the roof and flames were visible from kilometers away. Two hundred firefighters fought the fire and got it under control in less than three hours. Two firefighters suffered minor injuries.

The left wing of the Art Nouveau building was destroyed, the roof and most of enclosure walls collapsed. The amount of damage can rise up to 1 billion Czech crowns (approx. 40 million euro). Although a student music festival was organized in close surroundings, none were injured.

Mayor of Prague Pavel Bém promised the city will rebuild the Palace, but refused to comment immediately on the view of the new or renewed building.

The Industrial Palace was inaugurated in 1891. It was the biggest building on the exhibition grounds. Architect Bed?ich Münzberger used the glassed-in steel structures for the first time in the Czech lands. The building was 238 meters long and its main tower was 51 meters tall. It was used mainly for trade fairs and exhibitions, but also for concerts and other culture events.

The cause of the fire is under investigation, and could take a week to discover the cause. Press reports suggest the fire is connected to the October 9 murder of businessman Václav Ko?ka junior, whose father is engaged in the Incheba company and has been leasing the exhibition grounds since 2001. Václav Ko?ka senior is a friend of former Czech prime minister Ji?í Paroubek. However, authorities mentioned an accident – explosion of pressure gas cylinder – was the probable cause. Incheba said they have video of the explosion recorded from the security cameras.

USA — A US government report was issued Wednesday predicting the rise of heating bills due to colder temperatures and impacts Hurricanes Rita and Katrina had on the nation’s energy production.

Local forecasters predict that most of the US will have a warmer-than-expected winter this year. However, households that heat their homes by gas can expect to pay 29.8% more in heating bills. In the case of colder-than-expected weather, an increase of 66% in household heating costs is likely. In typical weather, prices will rise about 47.6%. Households that use electricity can expect a rise of about 5% from last year. NOAA‘s 2005-2006 U.S. Winter Outlook calls for warmer-than-normal temperatures across much of the central and western United States, including Alaska and Hawaii. The Midwest, the Southern Californian coast and the East Coast have equal chances of warmer, cooler or near-normal temperatures this winter.

Around one third of the US crude oil and one fifth of the natural gas outputs in Mexico still remain closed due to hurricane-related damage. Seven oil refineries remain offline.

The Energy Information Administration predicts that the price of oil will rise to around $64 per barrel (42 gallons or 158.97 litres) in 2006, with $58 being the average for this year.

Methane gas was blamed for the explosion deaths of 8 miners in southern Polish‘s Halemba coal mine Tuesday, November 21. Officials say at least 15 are missing.

Rescue efforts were halted because dangerously high levels of methane gas returned, according to Zbigniew Madej, spokesman for state-owned Coal Co., which operates the mine.

The missing miners’ locater devices were not emitting signals, increasing rescurers’ concerns for their well-being. Grzegorz Pawlaszek, head of Coal Co., said the 15 missing miners’ fate is “not known,” but added that “there is a chance to find someone still alive.”

“This is a tragedy. People have died here,” Polish Prime Minister Jaroslaw Kaczynski said when he came to Ruda Slaska to see the blast.

Earlier Wednesday, a reconnaissance rescue team descended 3000 feet toward the blast scene, only to retreat because of safety concerns related to high methane gas levels. Rescue digging efforts were also halted because of explosion concerns.

The missing men were aged 21-59. One of the miner’s family members, Andrzej Pytlik, 30, remained on scene with his sister, hoping and waiting for news of her husband, Krystian Gaszka.

Pytlik, also a miner, said through teary eyes that, “I work in the mines and I know that hope is scant because that’s the truth.”

The explosion occurred in a closed portion of the mine where the now-missing miners were working to retrieve abandoned equipment. According to Pawlaszek, the value of the equipment was $23 million, adding that “It was new equipment and that is why we decided to retrieve it.”

He indicated that the recovery work was performed under the supervision of gas detection specialists, and that the bodies of the recovered miners were difficult to identify because of the severity of burns and because their ID tags were blown away in the explosion.

The Halemba mine, located in Ruda Slaska, has produced coal for nearly 50 years, has been fraught with safety concerns and has a track record of serious accidents. One of the oldest mines in Poland, it is centrally located in the industrial Silesia region.

Earlier this year, a miner was trapped underground in the Halemba mine five days after a cave-in. In 1990, 19 miners were killed and 20 hurt in a gas explosion, and five were killed in collapse in 1991.

Inside, priests and mining officials were comforting and counseling with distraught relatives. Outside, eight white candles flickered on a main gate wall.

In February 2017, the Iranian Chess Federation announced two teenage chess players, Dorsa Derakhshani and her younger brother Borna Derakhshani, were banned from representing the national team. The federation announced their decision although Dorsa Derakhshani had previously decided and informed the chess federation she did not wish to play for Iran.

Dorsa Derakhshani is currently 21 years old and holds the International Master (IM) as well as Woman Grand Master (WGM) titles. Her brother, Borna, plays for the English Federation and holds the FIDE Master title.

Dorsa Derakhshani was banned since she did not wear a hijab, an Islamic headscarf, while competing at the Tradewise Gibraltar Chess Festival in January 2017. Under the laws of Islamic Republic of Iran, hijab is a mandatory dress code. Her brother Borna Deraskhsani was banned for playing against Israeli Grand Master (GM) Alexander Huzman at the same tournament. Iran does not recognise the existence of Israel, and previously, Irani athletes have avoided playing against Israeli athletes.

Mehrdad Pahlavanzadeh, the president of the country’s chess federation, explained the decision to ban the players saying, “As a first step, these two will be denied entry to all tournaments taking place in Iran and in the name of Iran, they will no longer be allowed the opportunity to be present on the national team.” ^{((fa))Farsi language: ?????? ????? ?? ??? ??? ?? ??? ????? ?? ?? ???? ???????? ?? ?? ????? ? ?? ??? ????? ?????? ??????? ????? ??????? ? ???? ???? ???? ?? ??? ??? ?? ??????? ????.} He further stated, “Unfortunately, something that should not have happened has happened and our national interest is paramount and we have reported this position to the Ministry of Sports.” ^{((fa))Farsi language: ????????? ?????? ?? ????? ????????? ?????? ??? ? ????? ??? ?? ?? ?? ???? ?????? ???? ? ?? ??? ???? ?? ?? ????? ???? ?? ????? ?????.}

IM Dorsa Derakhshani, who currently studies at Saint Louis University in the United States and plays for the United States Chess Federation, discussed her chess career, time in Iran and the 2017 controversy, and her life in Saint Louis with a Wikinews correspondent.

Ricky “The Hitman” Hatton regained the IBF light welterweight title belt he relinquished less than 12 months ago when he defeated Juan Urango in Las Vegas, Nevada tonight.

“The Hitman” won by unanimous decision, as the fight went to 12 rounds. Despite early match odds suggesting Hatton would dominate the fight, this was not the case. Each round was close, but most pundits and judges alike agreed that Urango only won 1 of the 12 rounds, with Hatton taking the other 11.

Despite the unfamiliar confines of Las Vegas, Hatton looked touched by the ringing of football fan-like chants, familiar in British boxing, that rang around the arena, as more than half of it was filled by traveling support from across the atlantic.

Many in the UK will hope Hatton has ended the “curse” that has seen names such as Frank Bruno, Naseem Hamed, Barry McGuigan and others fall short while headlining fights on “The Strip”.

From here, it is widely believed “The Hitman” will move on to fight Jose Luis Castillo in June, again likely in Vegas.
