Israel has continued its barrage of the Gaza Strip with an attack by a helicopter gunship on the office of the Palestinian prime minister. The attack, which left the building ablaze, injured three Palestinian security guards and was described by the prime minister, Ismail Haniya, as senseless. “This is the policy of the jungle and arrogance,” Haniya told Reuters. “They have targeted a symbol for the Palestinian people.”

Israel claims the attack on Gaza, codenamed Operation Summer Rains, is to pressure the Palestinian government into freeing Cpl. Gilad Shalit, the Israeli tank gunner Israel describes as having been kidnapped by Palestinian militants on Monday.

Other Israeli strikes on Saturday night hit a school in Gaza City and Hamas facilities in the town of Jabalia in the north of the strip where one 34-year-old Hamas operative was killed and another wounded.

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.

Troops from Saudi Arabia and the United Arab Emirates have arrived in Bahrain at the government’s request after major protests on Sunday.

An estimated 1,000 Saudi Arabian troops entered the country early Monday, followed by around 500 troops from the UAE. The troops entered as part of a broader deployment by the Cooperation Council for the Arab States of the Gulf (GCC), a regional group of six countries. It is unclear what purpose the troops are serving, though speculation is that they will guard major infrastructure facilities.

Al Wefaq, the leading opposition party, said it considered “the entry of any soldier or military machinery into the Kingdom of Bahrain’s air, sea or land territories a blatant occupation” and that the presence of foreign troops “puts the Bahraini people in real danger, and threatens them with an undeclared war by armed troops.”

Statements from the US government, a major Bahrain ally, said that “[t]his is not an invasion of a country” and that it urged both the Bahrain government and the GCC “to exercise restraint” and “act in a way that supports dialogue instead of undermining it.”

An official of Iranian Foreign Ministry also criticized the Saudi invasion of Bahrain, saying “it is surprising to see that immediately after the recent trip of the US Defense Secretary [Robert Gates] we see the intensified use of violence against the people of Bahrain.”

The intervention came a day after the country saw the worst protests since February, as several dozen people were injured in clashes with police.

Journalist, counselor, painter, and US 2012 Presidential candidate Joe Schriner of Cleveland, Ohio took some time to discuss his campaign with Wikinews in an interview.

Schriner previously ran for president in 2000, 2004, and 2008, but failed to gain much traction in the races. He announced his candidacy for the 2012 race immediately following the 2008 election. Schriner refers to himself as the “Average Joe” candidate, and advocates a pro-life and pro-environmentalist platform. He has been the subject of numerous newspaper articles, and has published public policy papers exploring solutions to American issues.

Wikinews reporter William Saturn? talks with Schriner and discusses his campaign.

Australian researchers say they have scientifically proven that stress causes sickness. The Garvan Institute in Sydney has discovered that a hormone, known as neuropeptide Y (NPY) is released into the body during times of stress. Their findings show the hormone can stop the immune system from functioning properly.

“Neuropeptide Y is one of those hormones that gets unregulated or released from neurones when stressful situations occur…it’s known for example that it regulates blood pressure and heart rates so your heart rate goes up but it hasn’t been known that it actually can affect immune cells as well,” said Professor Herbert Herzog, one of the researchers.

Herzog feels it is good to finally have proof of something people have suspected for so long.

“Now we have proven without doubt that there is a direct link and that stress can weaken the immune system and that makes you more vulnerable when you for example have a cold or flu and even in the more serious situations such as cancer can be enhanced in these situations,” said Herzog.

The Garvan Institute study centres on two key events that enable the human body to recognise foreign substances and control invaders. When our body encounters a pathogen (bacteria and viruses), the immune cells retain and interrogate suspects. Their activation is made possible by NPY. These cells then return to the lymph nodes, which are found all over the body, with information about the foreign invaders. The lymph nodes are where decisions about defence are made.

“Most of us expect to come down with a cold or other illness when we are under pressure, but until now we have mostly had circumstantial evidence for a link between the brain and the immune system,” said lead Garvan researcher, associate Professor Fabienne Mackay. “During periods of stress, nerves release a lot of NPY and it gets into the bloodstream, where it directly impacts on the cells in the immune system that look out for and destroy pathogens (bacteria and viruses) in the body.”

In the case of bacteria and viruses, TH1 cells are part of the attack team that is sent out on the ‘search and destroy’ mission. But when their job is done they need to be turned ‘off’ and the immune system reset. The same hormone, NPY, that activates the sentry cells now prompts the TH1 cells to slow down and die.

“Under normal conditions, circulating immune cells produce small amounts of NPY, which enables the immune cells on sentry duty and the TH1 immune cells to operate – it’s a yin and yang kind of situation. But too much NPY means that the TH1 attack is prevented despite the foreign invaders being identified – and this is what happens during stress,” added McKay.

The impact of stress on the body has been observed in athletes. Ph. D researcher at the University of Queensland, Luke Spence, together with the Australian Institute of Sport, studied elite and recreational athletes over five months.

They found elite athletes were more susceptible to respiratory diseases under stress.

“A lot of elite athletes put themselves through vast amounts of physical stress in their training, but also their emotional, psychological stress of feeling the pressure of Australia on their shoulders, wanting to compete and wanting to do their best,” said Spence.

It’s not just athletes who are prone to stress. Pressures at work and at home may cause emotional and mental stress that can be equally damaging. Almost a third of all work absenteeism in Australia is due to illness, costing employers over $10 billion a year.

“I think it has a huge impact for the work force and also for employers – if their employees are constantly stressed, constantly under pressure, they are more likely to get sick,” Spence said.

Further research could lead to the development of new drugs which may inhibit the action of the neuropeptide Y hormone.

Herzog warns people to minimise stress before it becomes a problem.

“Relaxation methods like yoga will help you to prevent that but there will still be people out there that are not responding to that and treatment by interfering with the system will be important,” he said. “There’s obviously some time until such a treatment will be available but this is something we will definitely work towards.”

The Garvan research will be published in the Journal of Experimental Medicine, Volume 202, No. 11.

An Atlas V rocket has successfully launched a classified spy satellite for the United States National Reconnaissance Office (NRO). The satellite, currently known to the public as NRO L-28, or Launch 28, is believed by amateur enthusiasts to be a signals intelligence (SIGINT) spacecraft, known by the codename Trumpet. The Atlas V carrier rocket flew in the 411 configutation, with a 4 metre diameter fairing, one solid rocket motor, and a single-engine Centaur upper stage.

The rocket lifted off from Vandenberg Air Force Base, Space Launch Complex 3 East (SLC-3E), at 10:02 GMT (03:02 local time) this morning. Today’s flight marks the thirteenth launch of the Atlas V, and the first Atlas V launch from Vandenberg. It is also the tenth orbital launch of 2008. The satellite entered a Molniya orbit, usually used by the NRO for SIGINT and communications satellites.

The launch was conducted by United Launch Alliance, a joint venture between Lockheed Martin, who designed and built the Atlas V, and Boeing, to provide EELV launches for the US Government. ULA president Michael Gass described the launch as “a proud moment in our company’s history”. The launch had been delayed by two years, from early 2006, due to a number of factors.

In addition to its reconnaissance payload, the satellite is carrying two small experiments. SBIRS-HEO 2 and TWINS-B. SBIRS is a test article for a missile detection system, slated to launch late this year or early next, and TWINS is a NASA infrared astronomy experiment. They will remain attached to the satellite for the duration of its mission.

Following the separation of the payload fairing, around five minutes after launch, all information on the launch was withheld, however about an hour into the flight, the launch was confirmed to have been successful. ULA will conduct its next launch on Saturday, when a Delta II will orbit a GPS satellite. The next Atlas launch is scheduled for mid-April, with the ICO G1 communication satellite.

Saudi Arabian military forces have continued their five-day attack against Yemeni rebels, leaving seven Saudis and an unknown number of Yemeni dead, according to the state news agency. The military has stated that only rebel forces on Saudi soil have been attacked, in contradiction with previous reports. Rebels have claimed that the military have targeted Yemeni villages.

An official at Samtah’s district hospital listed seven Saudis, of which four women civilians, as dead and 126 wounded since fighting began. He said Friday had been the “heaviest day” for casualties since Tuesday, leaving two soldiers dead and many wounded. According to Saudi media, rebel shelling killed the women, who were all from the same family.

According to the Saudi government the fighting began when rebels killed a Saudi border official and wounded eleven, going on to capture an area in the province of Jizan, though rebels say that border clashes had started earlier. The latest attacks took place after rebels disguised as women entered Saudi border villages on Friday night.

Rebels claim that Saudi ground troops have entered Yemeni territory, and that they have captured soldiers. They stated on their website that “[w]ith Allah’s help, the Saudi tyrannical advance into Yemen’s territory has been defeated […] A number of its troops have been captured and several military vehicles and supplies been seized.”

The Saudi government responded that the airstrikes were on Saudi border territory to repel the rebels, although on Thursday a Saudi government adviser informed reporters that jets had bombed rebel camps within Yemen with the Yemeni government’s blessing.

Relief agencies are concerned about providing aid to the tens of thousands displaced since the latest offensive started on August 11.
