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.

Workers at Newport Chemical Depot in Indiana have completed a successful test-run of a chemical reactor designed to dispose of Cold War stockpiles of VX nerve agent.

After encountering initial difficulties when the temperature in the reactor grew too high, workers were able to adjust the speed of the device. 180 gallons of VX and water were turned into a caustic but far less lethal compound, that can be further reprocessed into an inert substance.

A residue of 14 parts VX per billion remained; the Army’s eventual goal is less than 20 parts. One drop of VX can kill a grown man.

The conversion of the VX stockpiled at the facility is projected to take two years. Then the drain cleaner-like waste product with its small residue of VX will need to be sent to another facility for reprocessing into a safer, biodegradable compound.

A controversial plan has Dupont doing the reprocessing at their facility in New Jersey, and dumping the compound into the nearby Delaware River.

Early afternoon saw a shooting in the church parking lot of New Life Church, an Evangelical Megachurch, in Colorado Springs, Colorado, United States. According to a report quoting the church’s pastor four people were shot by a gunman in the car park.

At this time it is unknown if there is any connection with yesterday’s shooting approximately 70 miles away in Arvada, Colorado, where a gunman shot two and injured two people at Faith Bible Chapel’s missionary training centre in a dormitory.

Human rights group Amnesty International has released satellite images showing how the Zimbabwean community of Porta Farm, which once housed some 10,000 people, has been completely destroyed. Taken in 2002 and 2006, the photos starkly contrast the previous built-up area with the empty scrubland that remains.

According to Amnesty International, residents of Porta Farm were given less than 24 hours notice to leave their homes. Human rights monitors reported that several people died in the chaotic environment of the ensuing demolitions and forced evictions. Two children were reportedly among the dead.

Zimbabwe’s forced evictions programme (called Operation Murambatsvina) has been widely condemned both within Zimbabwe and beyond. A 2005 report on Operation Murambatsvina by United Nations Special Envoy Anna Tibaijuka estimated that it has cost 700,000 people their homes or livelihoods. She was present at Porta Farm during the second day of its demolition, and was shocked by the brutality of the evictions.

Residents of Porta Farm had fought eviction in the past, winning judgements from the High Court of Zimbabwe that they should not be evicted unless the government provided suitable alternative accommodation. However the High Court dismissed a contempt of court action that attempted to stop the 2005 evictions, giving no reason.

The Zimbabwean government (led by President Robert Mugabe) says that the programme is in the public interest and was not against the law. It has denied responsibility for the deaths.

Houston, Texas representative Al Edwards proposed a bill last week to ban “sexually suggestive” cheerleading in Texas high schools, middle schools, and elementary schools.

The movements typical to cheerleading are sexual, said Edwards, and send out the wrong message, especially as youth should be encouraged to be more reserved where sex is concerned. The penalty for schools that continue to allow the activity would be a cut in state funding.

Edwards filed the bill after witnessing several performances in his district.

Several others agree with Edwards’ proposal.

“Anything that promotes family-oriented behaviour is a good thing,” said Rhonda Roberts, a director for the United Spirit Association.

“I don’t think this law would really shake the industry at all. In fact, it would give parents a better feeling, mostly dads and boyfriends, too,” said J.M. Farias, who owns Austin Cheer Factory. He pointed out that cheering competitions frown on the movements in question.

Cheerleading is a recreational activity and sometimes competitive sport involving organised routines including elements of dance and gymnastics, to encourage crowds to cheer on sports teams. It is a popular activity practised by millions of American students. In Texas, there are competitions that start at the age of four.

A Proton rocket which was intended to launch the JCSAT-11 satellite into a geostationary transfer orbit lifted off and successfully completed its first stage burn, but the second stage failed leading to loss of the rocket and satellite.

The launch vehicle was a Proton M booster with a Breeze M upper stage. More than 300 Proton rockets have been launched, all from the Baikonur Cosmodrome in Kazakhstan. Following the launch failure, Kazakhstan suspended the launch of Proton rockets from Baikonur, Interfax news agency reported.

JSAT Corporation immediately placed an order with Lockheed Martin, the satellite manufacturer, for an identical replacement satellite based on the A2100AX design.
