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.

Officials in Mumbai, India, demolished over 6,000 shanties today in a push to eradicate the capital city’s slums. In total, 39,000 shanties have been flattened, displacing over 200,000 people, in the city’s biggest-ever demolition drive, which began in early December.

When complete, over 2 million people are expected to be displaced. After wiping out the least desirable shanties, next in line for demolition are the illegal ‘well-off’ shanties and neighborhoods, according to the legal and bureaucratic motions that have been executed toward cleaning up Mumbai’s appearance by lowering the dominance of shanties, which make up 62 percent of Mumbai’s housing.

“As far as eye can see, there are mounds of wood, tin and tarpaulin, the remains of 6,200 illegal homes, flattened by a heavy excavator running on tank-like tracks and giant motorised claws,” the Indian Express reported about today’s destruction. [1]

Chief Minister Vilasrao Deshmukh said that citizens would see a change within six months. “Every chief minister likes to be remembered, and I’m no exception,” said Deshmukh, who despite having an empty exchequer, also announced that Rs 31,000 crore will be spent on new roads, sea links and rail lines.

On Sunday, female ice hockey players from North and South Korea joined one another for a training session before the upcoming Winter Olympics. Players from the two Koreas are to compete together as a united team for the events hosted in Pyeongchang, South Korea, which are scheduled to start on February 9; Seoul’s Unification Ministry said. The cross-border gesture is part of diplomatic efforts to ease tensions on the divided Korean Peninsula and the team was approved by the International Olympic Committee.

The International Olympic Committee selected Pyeongchang in 2011 to host the event, marking South Korea’s first opportunity since the 1988 Summer Olympics in Seoul. The earlier event was marred by violence as North Korea had bombed a South Korean flight several months prior, killing over 100 and boycotted the event. Inter-Korean relations have changed considerably in the ensuing thirty years, including the two sending unified teams for table tennis and youth football in other non-Olympic competitions.

The announcement that the two countries would compete together was a stated goal of South Korean President Moon Jae-in. Last year, he announced the proposal and the two nations went into discussion this month. After two weeks, they made the announcement to field a consolidated 35-strong team of ice hockey players and have joint skiing exercises with both team coaches involved.

According to Yonhap News Agency estimates, about 80% of South Koreans support dialogue, but the move to have a joint team has been controversial. Over 10,000 South Korean citizens sent a petition to South Korean President Moon opposing the union and a group of North Korean defectors held a protest at the South Korean National Assembly on January 24, tearing apart photos of the North Korean leader, Kim Jong-un. Public support for eventual reunification of the Korean peninsula has waned in recent years, with the younger generation more skeptical of the possibility.

Commander Leroy Chiao (U.S.A.) and Flight Engineer Salizhan Sharipov (Russia), suited in Russian Orlan spacesuits, left the International Space Station on a 4.5 hour long spacewalk to install antennas for the European Automated Transfer Vehicle (ATV), inspect and photograph other exterior equipment and launched the Nanosatellite mini-satellite. This is the last scheduled walk for the Expedition 10 crew.

At 06:25 UTC, the two astronauts left the station from the Pirs DC1 docking compartment/airlock and proceeded to install the last three of six space-to-space communication antennas for the ATV’s rendezvous and docking with the ISS next year.

Sharipov next deployed the foot long, 11 pound Russian Nanosatellite, tossing it into space by hand. The object of the experiment is to develop small satellite control techniques, monitor satellite operations and develop new attitude system sensors. Russian ground crews reported good signal reception from the satellite two hours after its release.

The two astronauts next proceeded to the aft end of the Zvezda service module. A Global Positioning System (GPS) antenna and necessary cabling for the ATV was installed and the men worked their way back to the airlock.

The station maintained its attitude, despite the loss of a gyroscope earlier in the space station mission, until the end of the spacewalk. Chiao and Sharipov reported being a safe distance from the attitude adjustment thrusters. Russian ground control activated the jets and normal attitude ofthe station was regained.

They returned to the airlock at 1055 UTC, completing the mission an hour earlier than scheduled.

Chiao and Sharipov arrived on the station October 16, 2004. They are scheduled to return to Earth on April 25, 2005. This marks Sharipov’s second walk in space and Chiao’s sixth.

Christchurch, New Zealand‘s Jade stadium says they can host the 2011 Rugby World Cup final if Auckland can’t make a decision on whether or not they should build a new stadium on the waterfront or upgrade Auckland’s current stadium, Eden Park, costing NZ$500 million and $385 million respectively.

Jade Stadium would be able to host the final if they were to include temporary seating to accommodate 60,000 people, required by the International Rugby Board (IRB).

Gary Moore, mayor of Christchurch, said that if they were selected to host the final then they will ask the government for $80 million. The stadium is already planning for an upgrade, worth $60 million but that money will be funded from private and charitable organisations as well as the local and central governments. The current upgrade will see Jade stadium’s seating capacity grow to 43,000 and if they host a quarter-final or semi-final then temporary seating will increase the seats to 55,000.

Trevor Mallard, the Minister of Sport, said that the Auckland City Council and the Auckland Regional Council have both been given about two weeks to tell the government which decision it supports. If they cannot come to a decision then the final will most likely be given to Jade stadium, Christchurch. The least likeliest of all decisions, an upgrade of Carlaw park, but that is designated for a retirement home and on private land.

Mr Moore said that he and “stadium officials had offered Jade Stadium as a back-up final venue at a recent informal meeting with Mallard because of the continuing Auckland divisions over a site. This is about New Zealand Inc, not about Christchurch versus Auckland. What we have said to Trevor Mallard is we are able to put a stadium into Christchurch that would accommodate the numbers they would need as an insurance policy if Auckland cannot get its act together. The Government knows that when Christchurch or Canterbury puts its hand up it delivers with excellence.”

Bryan Pearson, chief executive of Vbase, the company which manages Jade Stadium, said: “It was not uncommon for major sporting venues to add temporary seating for big events. London had included temporary seating for some stadiums as part of its successful Olympic hosting bid. It was not a low-rent option, and was a commercially prudent way to marry short-term opportunity with long-term legacy.”

Mr Pearson hopes that Jade Stadium will not be used for the final as he understands why the government wants a national stadium, “Let’s hope this gets sorted and we can focus our attentions on playing a very major supporting role. We are only a third the size of Auckland, so what we can sustain post-World Cup is nowhere near what Auckland can.”

Warwick Taylor, former All Black, said it will be great if Christchurch can host the final even though he played in the 1987 final at Eden Park. Though Mr Taylor does say that an Auckland stadium is a better idea as a 60,000 seat stadium is more viable in such a large population city. Mr Taylor said that he “had great memories playing at Eden Park and in some ways would hate to see it lose the final. But I also like the idea of a national stadium.”

The New Zealand Rugby Union said that a waterfront stadium and an upgrade of Eden Park are the only two options being considered, and no other stadiums are being considered.

A lot of people are confirming that Christchurch will be able to cope with the huge amount of visitors that would arrive for the final as Christchurch has the highest per capita amount of restaurants and bars in Australasia. The city also features numerous hotels.

If New Zealand cannot deliver a final in a 60,000 seat World Class stadium then the IRB will allocated the final to another country.

Buffalo, New York —The Buffalo Fire Department and Police were called to a hazmat situation at Canisius College on Main Street after security reported that a one gallon glass container containing chloroform broke, spilling about a pint onto the floor of the college’s science building.

According to communications by firefighters, who arrived at around 8:20 a.m. (eastern time), the glass container spilled on the third floor in room 318. As a precaution the building was evacuated and East Delevan road between Main Street and Jefferson Avenues was closed to all vehicle and pedestrian traffic while crews worked to clean up the spill.

At about 9:15 hazmat crews entered the room and began to clean up the chemical “using kitty litter” and fans to air out the room. They then sealed the material in a five gallon container. At 9:23 a.m. firefighters stated that they no longer detected the chemical in the air and began to pack up their gear.

Officials for the college assessed the situation and decided to keep the building closed for the day. “At 8:22am this morning the Public Safety Department and Buffalo Fire Department responded to a report of a chemical spill on the third floor of the Health Science Center. As the building is cleaned, the Health Science Building will remain closed today and reopen tomorrow morning,” a college official said to Wikinews, adding they could not confirm the firefighter reports.

Firefighters believe the container containing the chemical was knocked over while someone working with maintenance was cleaning the floors.

There are no reports of injuries, but WKBW reports that the maintenance worker was taken to Sister’s of Saint Mercy’s hospital not far from the college for observation.

Chloroform is a common solvent used in chemistry laboratories. Minimal exposure can cause dizziness, headaches and fainting while prolonged exposure can cause liver and kidney damage. It is considered a hazardous material and environmentally unsafe. Banned as a consumer product since 1976 in the U.S., it was previously used in toothpaste, cough medicines and pharmaceuticals.
