Sri Lankan Ministry Of Foreign Affairs said the government accepts Beijing’s “One China” policy and that Taiwan is an inalienable part of the People’s Republic Of China, according to a March 17 press release.

The current foreign Ministry communiqué, recollects the press communiqué issued by the Foreign Ministers of China and Sri Lanka in Beijing in December 2004. Sri Lanka reiterated its support for Chinese legislative measures to oppose forces seeking to secede from China.

In the communiqué, the Sri Lankan government categorically mentioned, Sri Lanka opposes secessionist actions in any form and fully supports a process of peaceful national reunification. The Sri Lankan government further said, it welcomes growing cross-Straits economic and other exchanges such as the promotion of direct trade, mail, air and shipping links.

In the mean time, Chinese President Hu Jintao issued a presidential order regarding the promulgation of the Anti-Secession Law on March 14, which was adopted at the Third Session of the Tenth National People’s Congress, China’s top legislature.

This week, the Public Broadcasting Service aired a NOVA program titled “Dimming the Earth”, which presented research by leading scientists on the complex systems of our global climate and human activity’s effect on it. One of the largest interactions (or “inputs”) humans have with the atmosphere is the ever-increasing use of fossil fuels. Consumption has risen 2% per year for this decade.

Fossil fuels burnt in factories and automobiles send their waste into our atmosphere in two forms. The first is CO₂ and other greenhouse gases, which have received substantial attention in the last few years because of the way they trap heat in the atmosphere. The second is the tiny particles of sulfur dioxide, soot and ash, which scientists call aerosols (basically smog). Research into understanding the negative health effects of air pollution has resulted in the development of catalytic converters for cars as well as devices to remove particulate solids from industrial waste before it reaches the air.

More recently, atmospheric scientists have come upon the phenomenon of the reduction of direct sunlight reaching Earth’s surface— observing a nearly a 5% decline between 1960 and 1990, with evidence of a recovery since then. This has been dubbed the “global dimming” effect, and is probably due to the way these aerosols act upon clouds. It is important to realise that this does not represent a net loss of this much sunshine to the climate system – if so, large temperature declines would have been observed. Instead, the sunshine is absorbed elsewhere in the system, with a much smaller net loss.

Clouds form when moisture gathers around airborne particles, such as pollen or dust. Clouds formed by the aerosol particles emitted by fossil fuel consumption are made of many more tiny droplets than “natural” clouds. These smog-created clouds have two notable effects: they shield sunlight from reaching Earth’s surface and, due to water’s reflective nature, the millions of tiny droplets suspended in them reflect light back into space, allowing even less light to reach Earth.

Many scientists now believe that global dimming caused by these pollutants has mitigated the temperature rises brought about by global warming. Over the last thirty years, Earth’s temperature has increased by about 0.5 oC.

In the absence of global dimming, however, the Earth might be 0.3 oC warmer than it currently is, suggesting that a “tug-of-war” exists between greenhouse gases and particulates released by burning fossil fuels. Efforts to mitigate the human health dangers of smog have allowed more heat into our atmosphere and brought about a sharper increase in global warming.

Dr. James E. Hansen, professor at Columbia University and the head of the Goddard Institute for Space Studies [1], believes that if we continue on our current pattern, this warming could be as much as five degrees in the next thirty years and ten to fourteen degrees over the course of the century. Such a temperature rise would devastate life on Earth, likely bringing on a cascade of self-reinforcing warming effects. Earth’s forests drying and burning, a steady thawing of the Greenland and arctic ice sheets, and, most dangerous of all, a release of the methane hydrates that are now frozen at the bottom of the oceans, could remake the planet into something inhospitable to human life. Dr. Hansen warns that, according to his research, man has just 10 years to reduce greenhouse gases before global warming and other responses to human activity by Earth’s climate reach a “tipping point”, becoming unstoppable.

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.

Emily Perry, a British actress has died at the age of 100.

Born on June 28, 1907 in Torquay, Devon, England, she was known for playing Madge Allsop, Dame Edna Everage‘s long-suffering, silent “bridesmaid”; she began playing the role at the age of 80.

Barry Humphries (Dame Edna) said, “It is a great loss to me, she was a close friend.”

As an actress in her own right, her filmography is limited to her appearances with Dame Edna, except for a 1995 appearance, in her late eighties, on an episode of Last of the Summer Wine as “Mrs. Broadbent”.

She appeared as herself in Night of a Thousand Faces. Prior to gaining fame, Perry spent 25 years running a dancing school for children.

A massive earthquake, registering 7.0 on the moment magnitude scale, struck Haiti yesterday, destroying many buildings, disrupting communications, and burying an unknown number of people underneath rubble. Thousands of people are feared to have been killed by the tremors, which were felt as far away as Venezuela.

Witnesses say bodies were lining the streets of the capital, Port-au-Prince, after the quake struck on Tuesday afternoon, sending a cloud of dust from falling buildings into the sky. The quake was centered about sixteen kilometers from the capital, and struck at a depth of just ten kilometers, exacerbating the damage. At least 27 aftershocks were also recorded, the strongest of which came in at 5.5 and 5.9 magnitude. A tsunami alert was initially issued following the tremor, but it was retracted shortly afterwards.

Buildings across the capital have collapsed, including the presidential palace and the headquarters of the United Nations peacekeeping mission in Haiti. However, the president, René Préval, and his wife reportedly survived the collapse of the building. The country’s envoy to the United States believed damage costs could reach billions of dollars.

UN peacekeeping chief Alain Le Roy said many people were in the UN building when it went down and they remain unaccounted for. A Brazilian military official later said four Brazilian soldiers who were part of the UN mission were killed.

UN Peacekeeping Chief Alain LeRoy said the organisation is working to learn the fate of its personnel. “As we speak there are still over 100 people unaccounted for under the rubble. We do not know about their fate […] some people have been extracted out of the building – but only less than 10 for the time being. Some dead, some alive. So we do not know for the time being the fate of the others. But of course, we are extremely, extremely concerned.”

The Notre Dame of the Assumption Cathedral in Port-au-Prince was also destroyed, killing Joseph Serge Miot, the Archbishop of Port-au-Prince.

“[…] It would appear that all those who were in the building, including my friend [UN mission head] Hedi Annabi […] and all those who were with him and around him are dead,” said French Foreign Minister Bernard Kouchner. In a statement released yesterday, the UN remarked that “[f]or the moment, a large number of personnel remain unaccounted for.”

Hospitals in Port-au-Prince were reported to have collapsed, raising fears that the injured would not be able to receive treatment easily. “We have reports of some of the most important hospitals in Port-au-Prince have been severely impacted by the earthquake,” said Paul Conneally, the Head of Media for the International Federation of Red Cross and Red Crescent Societies.

“I saw dead bodies, people are screaming, they are on the street panicking, people are hurt. There are a lot of wounded, broken heads, broken arms,” recounted Raphaelle Chenet, the administrator of the Mercy and Sharing charity, in a telephone interview with the Wall Street Journal from the Haitian capital.

UN officials reported that communications and power are out across the city, making it difficult to get accurate details regarding the full extent of casualties and damage.

The UN also noted that the main prison in Port-au-Prince collapsed, and there were reports of inmates escaping. Spokeswoman Elisabeth Byrs, however, said she had no further details about that.

Efstathios Daras, the Greek ambassador to Venezuela who also represents Greece in Haiti, described the situation. “We fear major loss of life, maybe in the thousands or tens of thousands. Survivors are using their hands to help get trapped people out. There are fears of big aftershocks which could make the situation even worse. There is huge damage to the infrastructure. We can’t get through anymore. All phone lines are down.”

Joseph Guyler Delva, a reporter for Reuters, was in the area when the tremors struck. “Everything started shaking, people were screaming, houses started collapsing. It’s total chaos.”

Rachmani Domersant, an employee for Food for the Poor charity described the conditions on Port-au-Prince’s streets. “The whole city is in darkness, you have thousands of people sitting in the streets, with nowhere to go. I’ve seen seven to eight buildings, from office buildings to hotels and shopping stores, collapsed […] I think hundreds of casualties would be a serious understatement.”

President Rene Preval told the Miami Herald today that the aftermath of the disaster was “unimaginable”. “Parliament has collapsed. The tax office has collapsed. Schools have collapsed. Hospitals have collapsed […] There are a lot of schools that have a lot of dead people in them,” he said, adding that he believes thousands of people died.

The Red Cross in Geneva says that up to 3 million people have been affected. The international aid agency added that there is an urgent need for search and rescue volunteers as well as field hospitals, emergency health, water purification and telecommunications.

The World Food Program (WFP), which has a large staff on the ground, says the level of destruction indicates many of these people have been affected and will require help. The Director of the WFP office in Geneva, Charles Vincent, remarked that the first priority is to save lives. “To rescue people that are buried, that are trapped, etc. […] followed very rapidly by a big problem of water, sanitation, epidemic-problems of diseases that might be bred in that kind of situation,” he noted.

The Haitian ambassador to the United States, Raymond Joseph, told CNN the Caribbean nation is seeking US assistance, and called the quake a catastrophe of major proportions. “I’m quite sure we’re going to face a disaster of major proportion,” he said.

Separately, the Inter-American Development Bank said it will immediately approve a $200,000 grant for emergency assistance to Haiti. The funds will be used to provide food, water, medicine and temporary shelter for victims of the massive quake.

The US Agency for International Development is dispatching a disaster assistance response team to Haiti and commented that it will continue to provide additional support as needed.

The UN, meanwhile, dispatched approximately 37 search and rescue teams to assist Haitians from a global network. UN General Secretary Ban Ki-moon said that US$10 million worth of emergency funds would be used. “I have spoken with Mr. Clinton and we have agreed to mobilize our best assistance and rescue teams and try to reconstruct the Haitian economy. The UN will do whatever possible to help the Haitian people to overcome these difficulties,” Ban stated.

Ban noted that 3,000 UN peacekeepers were in Haiti, and that they secured the seaport and airport. They are trying to rescue people buried underneath rubble, he said, but were severely hampered by lack of heavy equipment. “Brazilian forces have been working through the night to rescue but because of the darkness and destruction of infrastructure not much progress has been made. We hope it will be better this morning,” Ban said.

The aid group Oxfam added that its emergency response team for Latin America is based in Haiti and is well prepared, with a public health, water and sanitation team in Port-au-Prince. Oxfam says it is preparing to send in emergency supplies as soon as possible from Panama.

The American Red Cross pledged US$500,000 to help the country, and would send out people to assess damage. “As with most earthquakes, we expect to see immediate needs for food, water, temporary shelter, medical services and emotional support,” it said yesterday evening in a statement.

A number of other nations, including the UK and Venezuela, are also planning to send aid.

A reporter for the Al Jazeera news agency, however, said there might be difficulties delivering aid. “We are about 300km from the epicentre of the earthquake, and we know that the UN agencies and the humanitarian groups here are trying to get together some kind of strategy to get aid over to Haiti. We know that there are trucks loaded with supplies ready to go but the difficulty is that no-one really knows how to get that aid to the people [effectively].”

This quake is said to have been the strongest in Haiti in over two hundred years; the last time an earthquake of comparable magnitude was recorded was in 1770.

Haiti is the Western Hemisphere’s poorest country. Recent development efforts have suffered severe setbacks because of political violence, crime, corruption and natural disasters. Seventy percent of the population lives on the equivalent of less than US$2 per day.

British explorer and mountaineer Edward “Bear” Grylls, has set a new altitude record by piloting a powered paraglider above Mount Everest reaching 29,494ft (8,990m). He and his fellow pilot, Giles Cardozo, who had invented and developed the parajet engine, set out on their attempt from the Himalayan village of Pheriche (altitude 14,435ft (4,400m)) in the early morning of 14th May.

Grylls, 33, is a mountaineer, best selling author and television presenter who spent three years with the elite British Special Air Service (“SAS”) forces. During this time he was involved in a horrific parachuting accident in which he broke his back in three places, almost severing his spinal cord. Remarkably, in 1998, after months of rehabilitation, he became at 23, the youngest British climber to scale Mount Everest and return alive.

Cardozo is considered to be one of the top paragliding pilots in the world, and it is reported that he and Grylls first came up with the idea for the attempt about a year ago when he had invented the engine that would take them up the mountain.

Grylls and Cardozo flew their paragliders together to 28,001ft (8,353m) surviving temperatures of minus 76°F (-60°C) and dangerously low oxygen levels, when a fault developed in Cardozo’s engine, and he had to abort his attempt just 984ft (300m) below the summit. Grylls went on to reach his record height at 09.33 local time. He had originally intended to cross the Mountain but turned back to base camp fearing that he might be arrested if he entered Chinese airspace.

On his return to Kathmandu, Grylls voiced his feelings of loneliness and exhilaration:

The attempt was sponsored by British technology and engineering group GKN. The project, GKN Mission Everest, raised £500,000 (approximately $1m) for Global Angels, a charity helping children in Africa, Asia and Latin America.

In a separate incident, a German paragliding champion has survived being sucked up by a storm to a height of 32,612ft (9,940m) whilst preparing for a world paragliding championship in Manilla, New South Wales, Australia.

Ewa Wisnierska, 35, the 2005 World Cup paragliding winner, lost consciousness and was covered in ice and battered by orange-sized hailstones as she was pulled upwards by the sudden tornado-like storm which she had been attempting to skirt. After regaining consciousness as she descended she was able to make contact with her ground team which had been tracking her by her GPS equipment, and landed safely 40 miles (60km) from where she took off.

Remarkably she spent only an hour in hospital after her experience, being treated for frostbite and blistering to her face and ears.

A fellow competitor, 42 year old Chinese man, He Zhongpin, who was also caught up in the storm, was not so fortunate and died from lack of oxygen and the extreme cold.
