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 Australian House of Representatives heard the traditional right-of-reply to the Budget released May 9, from the Australian Labor Party, led by Kim Beazley (Labor, Brand), plus Budget replies from minor parties in the Australian Senate.

While the Budget is politically popular, having as one of its main features significant tax reform, Beazley focused on the omissions in the Budget, such as the failure to address a skills shortage.

A lahar at New Zealand’s Mount Ruapehu is all but over, without causing anywhere the level of havoc for which authorities were prepared.

The event was first confirmed by a 3 News helicopter, and then the Department of Conservation.

The Department of Conservation had said that a “moderate lahar” was moving down the side of Mount Ruapehu.

The lahar travelled down the Whangaehu Valley, past the Tongariro catchment; and then continued on to the Tangiwai Bridge, the site of the 1953 Tangiwai disaster, which was itself caused by a lahar.

The crater lake is currently being reported by a free phone number as at a warning level of 3a. The crater lake is also being reported at a level between 5.7-6.7 metres up the Crater Lake tephra dam.

The lahar emergency plan was activated by Civil Defence. The district mayor of Ruapehu, Sue Morris, and conservation minister, Chris Carter, said that the authorities had been very quick to respond to the emergency. All three electronic surveillance technologies had their alarms activated. Mr Carter said, “The lahar travelled down the path as predicted, and the early warning response system that this government provided worked exactly as planned.”

Highways near Mount Ruapehu were closed by the Ohakune police, including the Desert Road. The roads have now been re-opened.

A lahar has been expected for a long time now, and scientists say the lahar could have been caused by, among other things, the bad weather New Zealand has been having lately.

Since 1996 the water level in the crater lake at the top of Mount Ruapehu has been rising, which created a risk of a lahar last year.

Natural Balance Pet Foods has recalled some of its wet and dry food for cats and dogs after several owners said that their pets were becoming sick. The company urges owners to stop feeding their pets the food immediately.

The brands recalled include Venison & Brown Rice Dry Dog Food and Venison & Green Pea Dry Cat Food.

Last month, Menu Foods recalled all of its 60 million products of dry and wet dog and cat food after pets began to fall ill and in some cases died of kidney failure.

“Natural Balance, Pacoima, CA, is issuing a voluntary nationwide recall for all of its Venison dog products and the dry Venison cat food only, regardless of date codes. The recalled products include Venison and Brown Rice canned and bagged dog foods, Venison and Brown Rice dog treats, and Venison and Green Pea dry cat food. Recent laboratory results show that the products contain melamine. We believe the source of the melamine is a rice protein concentrate. Natural Balance has confirmed this morning that some production batches of these products may contain melamine,” said a press released issued by Natural Balance.

The FDA states that the “investigation remains open and active, and the agency continues to follow leads to get closer to the root cause of the problem and to ensure that all contaminated product is removed from the market.”

“The source of the melamine appears to be a rice protein concentrate, which was recently added to the dry venison formulas. Natural Balance does not use wheat gluten, which was associated with the previous melamine contamination,” said the press release.

Bags, cans and zip lock bags of the food are expected to be the most affected.

“The products are packaged in bags, cans and zip lock treat bags and sold in pet specialty stores and PetCo nationally. No other Natural Balance products are involved in this voluntary recall as none of our other formulas include the rice protein concentrate,” added the press release.

The company states that the food, Venison & Brown Rice Dry Dog Food and Venison & Green Pea Dry Cat Food, are the only brands affected by the recall.

Following a similar experiment in 2009, six men entered an enclosed room in Moscow last Thursday to simulate a flight to Mars. The Mars-500 team consist of a Chinese man, a Frenchman, an Italian, and three Russians. Only the Chinese man, Wang Yue, is a trained astronaut. The six waved goodbye, crying “see you in 520 days’ time!”.

According to Wang, not being able to see their families and friends was one of the greatest challenges, although e-mail is allowed during the experiment. Both Wang and the Frenchman, Romain Charles, expressed pride to be part of this experiment. Wang said, “it will be trying for all of us. We cannot see our family, we cannot see our friends, but I think it is all a glorious time in our lives.”

The joint-effort project is being organised by the Russian Institute for Biomedical Problems (IBMP) and the European Space Agency; the goal is to study physical and psychological effects on would-be astronauts. All six men speak reasonable English; however, as Russian is another primary language for the simulated trip, Russian crew member Sukhrob Kamolov said body language will be used should they fail to understand one another.

Food for the volunteers will be rationed as it would in a real Mars mission. All supplies were supplied by China and loaded into the ‘simulated spacecraft’ prior to the beginning of the experiment. For backup, China is sending three mission support staff to Russia.

No women are included in the crew, excluding issues relating to a mixed-sex crew from the study. During a similar experiment in 1999, a woman complained that the captain attempted to kiss her.

Following 250 days of “travelling” to Mars, the group will split. Three will stay in the “spacecraft”, the other three going to the surface of “Mars”. Only two will actually leave the “spacecraft” to study the surface of “Mars”. After a month, the group will go through the return journey simulation, a 240 day trip. The men will follow a strict timetable, with 8 hours each of sleep, work, and leisure each day.

A Russian submarine trapped during a training exercise in Berezov Bay, 75 km south of Petropavlovsk in Kamchatka, has been rescued after it was cut free by a Royal Navy Remotely Operated Vehicle (ROV). The crew of seven officers and midshipmen, who spent three days in temperatures around 6^oC and were running out of oxygen supplies, were unharmed.

The submarine appeared on the surface at 4:15 p.m. local time. “The crew opened the hatch and climbed the rescue ship’s deck on their own,” said Admiral Victor Fyedorov. The first aid to the crew was given on ship Alagez, and they were transferred to Petropavlovsk-Kamchatka hospital.

The British Scorpio ROV cut fishing nets and debris, freeing the trapped submarine. “The rescue operation was completed successfully. We thank everyone, and especially the British rescue crew,” said Fyedorov.

The submarine will be repaired and modernized. “After salvaging it, AS-28 will be carried on one of the rescue ship’s decks to the coast, where specialists will examine it,” said a spokesperson of VMS (“Company for secondary metal and boats”). Russian President Vladimir Putin has pledged an inquiry into the incident.

The United States and Japan also sent equipment to help in the rescue. However, it was not used.

Portal and search company Yahoo! has purchased Ludicorp Research and Development Ltd., the private corporation which owns the photo sharing site Flickr.The news was officially disclosed in a Sunday posting to the corporation’s staff blog and is credited to Caterina Fake, Flickr’s vice president of marketing and community. The posting announced the sale, but did not disclose details of the deal. In a report by Silicon.Com, Yahoo! spokeswoman Joanna Stevens confirmed the deal on Sunday but also did not disclose the terms.

Both Fake and Stevens said Flickr will remain independent. Stevens added that Flickr’s employees will relocate to the Yahoo! headquarters in Sunnyvale, California later this year.

Rumors of the sale have been circulating amongst bloggers for some time, though neither company would confirm or deny the rumored sale. Other rumors had Google or AOL as Flickr’s probable suitor.

Flickr allows users to upload pictures from their computers, digital cameras, or camera phones to a personal website where they can display them, engage in photo blogging and create photo albums. The graphics may be licensed under a variety copyright license schemes including public domain, and photo owners can be easily contacted through the website.

Yahoo! had earlier announced Yahoo! 360°, a blogging service with sharing privileges and integration with other Yahoo! services such as internet broadcasting and instant messaging.
