As gas prices have risen in the United States, the regional transport authority for southeastern Pennsylvania, SEPTA, has seen a sharp increase in ridership, which has caused overcrowding on the trains.

“As fuel prices have continued to rise, SEPTA ridership has steadily increased and is the highest in 18 years,” said SEPTA General Manager Joseph Casey. Monthly ridership was 22 percent higher last month than a year ago.

“They have crushed loads on their rail lines, already where people are standing, and there’s not enough seats,” said Rich Bickel, the director of the Delaware Valley Regional Planning Commission.

“At peak times some railcars are standing room only and commuter parking lots are nearly full. All Regional Rail lines are running near full capacity and the train station parking lots are at about 90 percent capacity or more,” SEPTA spokesperson Felipe Suarez said.

While SEPTA awaits new Silverliner V trains from Hyundai Rotem, which begin arriving in 2009, it had hoped to lease eight rail cars from New Jersey Transit, at an agreed-upon rate of US$10,000 per month. However, due to problems with insurance and liability indemnification, the deal fell through, according to Casey.

SEPTA has entered a new agreement to purchase the eight rail cars from NJ Transit. The transit authority will pay US$670,000 for the cars and assorted supplies plus one additional inoperative car which will be used for spare parts. The rail cars will be operated using a SEPTA provided locomotive as they are not self-propelled.

The cars are being disposed of by NJ Transit because it has switched from single-floor cars to double-decker cars.

SEPTA is expecting to raise US$3.1 million by selling rail that has been out of service since 1981 at auction.

In a press release earlier today, New York State Agriculture Commissioner Patrick Hooker, along with Dean of Cornell University’s College of Veterinary Medicine Donald F. Smith, confirmed that scientists at the New York State Food Laboratory identified Aminopterin as a toxin present in cat food samples from Menu Foods.

Menu Foods is the manufacturer of several brands of cat and dog food subject to a March 16, 2007 recall.

Aminopterin is a drug used in chemotherapy for its immunosuppressive properties and, in some areas outside the US, as a rat poison. Earlier reports stated that wheat gluten was a factor being investigated, and officials now state that the toxin would have come from Chinese wheat used in the pet food, where it is used for pest control. Investigators will not say that this is the only contaminant found in the recalled food, but knowing the identity of the toxin should assist veterinarians treating affected animals.

The Food Laboratory tested samples of cat food received from a toxicologist at the New York State Animal Health Diagnostic Center at Cornell University. The samples were found to contain the rodenticide at levels of at least 40 parts per million.

Commissioner Hooker stated, “We are pleased that the expertise of our New York State Food Laboratory was able to contribute to identifying the agent that caused numerous illnesses and deaths in dogs and cats across the nation.”

The press release suggests Aminopterin, a derivative of folic acid, can cause cancer and birth defects in humans and can cause kidney damage in dogs and cats. Aminopterin is not permitted for use in the United States.

The New York State Food Laboratory is part of the Federal Food Emergency Response Network (FERN) and as such, is capable of running a number of unique poison/toxin tests on food, including the test that identified Aminopterin.

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.
