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.

New Orleans, Louisiana —After Category 4 storm Hurricane Katrina slammed into New Orleans, on the night before August 29, 2005, several flood control constructions failed. Much of the city flooded through the openings. One of these was the flood wall forming one side of the 17th Street Canal, near Lake Pontchartrain. The U.S. Army Corps of Engineers (USACE) is the primary agency for engineering support during such emergencies. A USACE team was assessing the situation in New Orleans on the 29th, water flow was stopped September 2nd, and the breach was closed on September 5th.

The Internet group Anonymous today held further protests critical of the Church of Scientology.

The global protests started in Australia where several hundred protesters gathered at different locations for peaceful protests.

In a global speech, the Internet protest movement said Scientology “betrayed the trust of its members, [had] taken their money, their rights, and at times their very lives.” The protesters welcomed the public interest their protests have led to, and claimed they witnessed “an unprecedented flood of Scientologists [joining] us across the world to testify about these abuses.” The group said it would continue with monthly actions.

In a press statement from its European headquarters, Scientology accused the anonymous protesters of “hate speech and hate crimes”, alleging that security measures were necessary because of death threats and bomb threats. This also makes the Church want to “identify members” of the group it brands as “cyber-terrorists”.

Wikinews had correspondents in a number of protest locations to report on the events.

Anonymous states that the next protest is scheduled to take place on April 18, which happens to be the birthday of Suri, the daughter of Tom and Katie Cruise.

Oscar Diös is a Swedish businessman looking to invest in a new project within the aviation community. He’s already bought the venture’s first airliner, a Boeing 747-200.

However, his intention is not to start an airline, and the jet is not intended for flight. Instead, he plans to convert the airliner into a unique business which he calls the ‘Jumbo Hostel’. The 450-seat widebodied jetliner will have 25 rooms sleeping a total of 85 people, including some in a luxury suite in the cockpit, and will sit at the entrance to Stockholm-Arlanda Airport.

Built in 1976, the aircraft was an “old wreck” when acquired, according to Oscar. The aircraft was being offered for sale at Stolkholm-Arlanda after previous owner Transjet became bankrupt. The airframe has then been completely gutted and is being fitted with a new, modernised interior. Each room contains three bunk beds. A cafe and a walkway across the left wing are also featured.

The airliner will sit on a concrete platform at the airport’s entrance, with its landing gear secured in steel cradles. It is intended to offer a good view of the day-to-day operation of the airport.

The hostel, which is to open in December, is aimed at families with children, aviation enthusiasts, low-budget travelers and people catching early morning flights who wish to leave it as late as possible before rising to get to check-in – unlike its competitors, the Jumbo Hostel is ten minutes walk from the check-in desks.

Wikinews conducted an email interview with Oscar Diös to talk about the hostel. The full exclusive interview is available below.

Preparations are underway ahead of the 2013 IPC Alpine Skiing World Championship, with a flag exchange taking place Tuesday, volunteer recruitment ongoing, USParalympics unveiling a new uniform for their team, skiers like the United States’s Jon Lujan actively training for the event and other skiers competing in preparation for the Championships in a World Cup event Wednesday.

Tuesday in La Molina, Spain, the president of Governmental Railways of Catalonia, Enric Ticó, and the mayor of Alp, Ramon Moliner, were gifted with flags by representatives of the International Paralympic Committee (IPC) and Catalan Government at a ceremony in Colet Museum of Barcelona at one of the first official events ahead of the 2013 IPC Alpine Skiing World Championship, which starts next week. As of Wednesday, event organisers were still seeking volunteers to assist with running the Championship. The opening ceremonies are scheduled for next Tuesday.

Entering the event, skiers had the opportunity to qualify through eight World Cup events held with only two disciplines on the program, Giant Slalom and Slalom. The first four were held in Sestriere, Italy, with the most recent four all being held in St. Moritz, Switzerland. Standing female French skier Marie Bochet has won six World Cups ahead of the World Championships and is considered by event organizers as a favorite in the standing group. Russian standing skier Alexey Bugaev is also considered a favorite by organisers as he won two Slalom and one Giant Slalom World Cup competition. In the women’s sit-ski, German Anna Schaffelhuber is considered the favorite having prepared for the Championships by winning five of the eight World Cup events. On the men’s sit-ski side, Japanese Takeshi Suzuki and Swiss Christoph Kunz both earned three World Cup victories in the lead up to this competition. In the women’s visually impaired group, Slovak Henrieta Farkasova will enter the competition with five World Cup victories. On the men’s side, Spanish Jon Santacana is favored to win with three Giant Slalom and one Slalom victory during this year’s World Cup events in the lead up to the World Championships.

British Combined Services Disabled Ski Team coach Mark Scorgie has noted that this year’s European ski season has been problematic with weather interfering with most competitions. Poor weather conditions continued Wednesday Rogla IPC Alpine World Cup, with the first Giant Slalom run canceled because of high winds.

The World Championships includes over 270 skiers, guides, coaches and support personnel from 28 countries including Spain, France, Australia, Ukraine, Netherlands, Croatia, Finland, Switzerland, Japan, Korea, Mexico, Turkey, Belgium, Norway, Russia, Britain, Germany, Italy, Canada, Slovakia, Czech Republic, United States, Austria, New Zealand, Sweden, Hungary, and South Africa..

The Spanish team includes blind skier Jon Santacana and his guide Miguel Galindo, and blind skier Gabriel Gorce and his guide Arnau Ferrer. Both vision-impaired skiers are scheduled to compete in the Downhill, Super G, Super Combined, Giant Slalom, and Slalom competitions. Also on the Spanish team are LW2 classified standing skier Úrsula Pueyo, LW12-1 classified sit skier Óscar Espallargas, and LW10-1 classified sit skier Nathalie Carpanedo who qualified as a wildcard entry. Pueyo, Espallargas, and Carpanedo are all scheduled to compete in the Slalom and Giant Slalom competitions. Accompanying the team are to be coaches Javier Gutierrez, Jordi Carbonell, and Andres Gomez, medical staff including Pablo Marquez and Josep Barrachina, and technical staffer Josep Bort.

The United States team consists of Seattle, Washington-based vision-impaired skier Mark Bathum and his Colorado Springs-based guide Jessica Smith; Park City, Utah-based vision-impaired skier Danelle Umstead and guide Rob Umstead; retired Army and Clarksville, Tennessee-based Heath Calhoun; Brooklyn, New York-based Ralph Green; Colorado Springs-based Allison Jones; Palmer, Alaska-based Andrew Kurka; Burlington, Vermont-based Stephen Lawler; retired Marine and Littleton, Colorado-based Jon Lujan; Farmington, New Mexico-based Alana Nichols; Wenham, Massachusetts-based Laurie Stephens; Park City, Utah-based Stephani Victor; Franconia, New Hampshire-based Tyler Walker; and retired Coast Guard and Campton, New Hampshire-based Chris Devlin-Young.

With five active cases of the Delta variant of COVID-19, South Australia begun a one-week lockdown on Monday. Announcing the lockdown, state Premier Steven Marshall declared “we have no alternative but to impose some fairly heavy and immediate restrictions”.

The first case out of South Australia’s active cases was presented to Modbury Hospital on Sunday night, having returned from Argentina earlier this month. The fifth, which Premier Marshall noted as “far more worrying”, visited The Greek on Halifax restaurant at the same time as someone who was later confirmed to be carrying the virus. Chief Public Health Officer for the state Nicola Spurrier said “if anyone has been at The Greek on Halifax they need to get into quarantine and get tested”.

In accordance with new regulations, there are only five reasons for South Australians to leave home: essential work, shopping for essential goods such as food, exercise, but only with people from the same household and within 2.5 kilometers (2 mi) of home, medical reasons (which includes testing and vaccination against the coronavirus, but excludes elective and cosmetic surgery), and caregiving.

Schools have closed for all but children of essential workers, with online learning having begun on Thursday. Face masks are also be mandated for those who leave home. ABC News reported that “support for businesses is expected to be announced…”, with all non-essential retail required to close under the new regulations.

Testing began on a chemical reactor at the Newport Chemical Depot near Terre Haute, Indiana on Friday morning. If successful, the reactor will be put to use destroying the large VX nerve gas stockpiles stored at the facility over the course of the next two years. After the disposal project experienced several delays, the facility announced it would begin pumping VX into a completed disposal unit for testing. The unit consists of a chemical reactor in which the VX will be mixed with water and sodium hydroxide, heated to 194°F while mixed with paddles. The resulting chemical, called hydrolysate, is chemically similar to commercial drain cleaners and has similar properties. If the test is successfully completed , the unit will continue processing the VX until the entire stockpile has been neutralized, a process projected to take two years. Administrators expect to complete testing on May 10, 2005.

According to the controversial plan, the finished waste product would be shipped to New Jersey for final reprocessing. The inert chemical would then be emptied into the Delaware River where natural attenuation would occur.

Residents near the proposed river disposal site in New Jersey oppose this idea. The contractor for the final component of this disposal would be the DuPont Corporation.

NCD is a bulk chemical storage and destruction facility in west central Indiana, thirty miles north of Terre Haute. Originally founded during World War II to produce RDX, a conventional explosive, it later became a site for chemical weapons manufacturing during the Cold War. It is now used to securely store and gradually neutralize part of the US stockpile of VX.

VX was manufactured by the U.S. in the 1950s and 60’s as a deterrent to possible Soviet Union use. It was never deployed, and the manufacture was halted in 1969 after an order signed by then-president Richard Nixon.

In 1999, the Army announced it awarded a disposal contract to Parsons Infrastructure & Technology, Inc., a business unit of Parsons Corporation. Some 220 civilian Parsons employees work at the facility, which is supervised by an Army officer reporting to the U.S. Army Chemical Materials Agency, and a board of civilian government overseers called the Indiana Citizens’ Advisory Commission, some of whose members are appointed by the state governor.

Security at the facility is controversial. A private security service, supplemented by a complement of Indiana National Guard soldiers, guarded the facility until April 14, 2005, when the soldiers were withdrawn. An Indianapolis television station has questioned security measures in some of its special reports.

At UCLA, a team of researchers has developed a harmless version of HIV that is designed to seek out, and potentially destroy, cancer cells.

In a laboratory-mouse experiment, the treated cells headed directly for melonoma and lung cancer cells, clustering around them with a surprising level of intuitiveness. Gene therapy for cancer has been at an impasse for the last 20 years, said the team, but now an effective carrier has been found in the most unlikely of sources. Essentially, one of the world’s largest health threats is now being considered to fight another.

Says Dr. Irvin Chen, from UCLA’s AIDS Institute, “The disarmed AIDS virus acts like a Trojan horse, transporting therapeutic agents to a targeted part of the body, such as the lungs, where tumors often spread.”

First the virus’s coating is removed and the virus is reprogrammed so that it recognizes and attaches to the p-lipoproteins of a cancer cell, one of cancer’s primary defenses. The retro-virus was also altered with a fluorescent protein for easy tracking within the lab mice. The next step will be to graft a cancer-killing gene onto the modified AIDS virus’s genetic structure.

Currently, a case of melanoma skin cancer spreading to the lungs is a confirmed death sentence. Should this method of treatment improve into a workable treatment, both life-threatening cancers and the AIDS retro-virus could be effectively neutered. But the team cautions that the treatment is in the very early stages and will take several more years to develop.
