Halifax, Nova Scotia

Following the first major snow storm of the season, several cars were reported to be ‘entrapped’ by slick ice in the seaside city of Halifax, Nova Scotia. The ice was believed to be created when the snow, which fell during the night of December 9-10, was packed down by successive cars and trucks passing over it. By morning, several areas of the city had patches of slippery, low-traction crystalline water lying in wait for the next unsuspecting motor vehicle to pass over them. Soon enough, your correspondent witnessed cars which had slowed to a stop or were parked find that, try as they might, they were unable to move forward on the ice and were therefore stuck.

Luckily, most of the cars were able to extricate themselves after either slowly accelerating in a low gear, or ‘rocking’ the car back-and-forth to build up momentum. No one was reported injured, and the only damage believed to be done was the excessive wear and tear on the entrapped vehicles.

Qatari non-profit organization Gulf Organization for Research and Development (GORD) launched a low emissions car at the 2012 United Nations Climate Change Conference (COP 18) in Doha. The car was designed and developed in Qatar.

Revealed during a press conference at the Qatar National Convention Centre, the car in addition to an internal combustion engine, includes an automotive thermoelectric generator designed to capture waste heat to produce hydrogen. GORD expects the heat waste collecting system to be compatible with any gasoline or compressed natural gas car.

GORD chairman Dr Al-Horr summarised the key concepts of the invention in a statement saying, “Our car produces electricity at no cost by capturing thermal waste energy, reducing costs and eliminating the need for an external source of electricity. Also, bulky compressed-hydrogen cylinders are a thing of the past, as our concept accomplishes the production of hydrogen by using water through fuel cells integrated within the car.”

Most of the energy in Qatari vehicle comes from the the car’s gasoline tank, supplemented by a thin film photo-voltaic panel on the roof. Normally in a combustion engine, chemical energy stored in a fuel, such as gasoline, is converted into heat energy through combustion. This heat energy is then converted into mechanical energy, manifested as an increase in pressure in the combustion chamber due to the kinetic energy of the combustion gases. The kinetic energy of these combustion gases are then converted into work; because of the inefficiencies in converting chemical energy into useful work, internal combustion engines have a theoretical maximum effiecincy of 37% (with what is achievable in day to day applications being about half of this). Of the chemical energy in the consumed fuel used by an internal combustion engine 40% is dissipated as waste heat. However, the Qatari vehicle uses a thermoelectric generator to convert this waste heat into electricity. Such generators are used in space vehicles, and produce electricity when thermoelectric materials are subjected to a temperature gradient, the greater the gradient the greater the amount of electrcity produced. In the GORD vehicle the electricity produced is used to electrolyse potable water to produce hydrogen which can be introduced into the vehicle’s existing fuel system.

The researchers showed that the heat waste collection engine caused a decrease in the car’s emissions, including a decrease of carbon monoxide and nitrous oxide emissions by more than 50%, the fuel efficiency increasing by 20%. On its website, GORD said that the heat waste collector engine is universal, “Any car can be adapted to accommodate the system as it doesn’t alter any electro-mechanical systems”.

West Mercia Police have made the announcement that a five-year-old girl that was physically involved in a crash involving a car going into a river has died in Birmingham Children’s Hospital, United Kingdom. The child has been identified as Gabrielle Grady. She was also known as Gabby.

Gabrielle was involved in a vehicle crash on Thursday when the car she was in crashed into the River Avon in the town of Evesham in Worcestershire, England. There were three occupants in the Vauxhall Vectra, including Gabrielle, her six-year-old brother Ryan, and her 41-year-old father Chris Grady, who was driving the vehicle. It took 12 minutes for divers to free Gabrielle from the car, which was partially underwater.

West Mercia Police announced on Sunday that Gabby had died in Birmingham Children’s Hospital at approximately 1330 (1:30 pm) GMT that day. From the time of her entry into the hospital, she was considered to be in a critical condition. Her family was with her at the time of her death. West Mercia Police also commented that Ryan was still recovering in the hospital.

This incident is currently being treated as suspicious, with Chris Grady being remanded in custody for offences of attempted murder. The police have stated that this incident is currently being handled as a murder investigation.

Knut, Germany’s famous polar bear, turned one at the Berlin Zoo yesterday. For the celebration he had a healthy cake with fruits and vegetables, fish and rice on lettuce topped with a candle-shaped rolling pin.

The director of the zoo, Bernhard Blaszkiewitz, said: “I wish Knut that he will get as old as polar bears are supposed to get. So minimum 30 to 40 years, and that he finds a partner.” The way he looks and because he comes from Berlin, he will reproduce well, Blaszkiewitz said. Along with this, he referred to the high birth rate in Berlin.

When Knut was born a year ago, he was rejected by his mother Tosca. Keeper Thomas Dörflein took a parental role and reared Knut by hand. After a few months, Knut grew big and Thomas Dörflein could no longer play with him because he received bad bruises. At birth, Knut weighed 1.8 pounds, today, he weighs 220 pounds. Adult male polar bears can weigh up to 800 pounds.

Knut was the first polar bear born at the Berlin Zoo in 30 years. Millions of people came to see him from all over the world and the event which was dubbed “Knutmania” spawned a CD, a book and hour-long queues at the zoo.

In solidarity with the Occupy Wall Street and other “Occupy” protests, activists set up camp outside St Paul’s Cathedral in London on Saturday, and they plan to remain indefinitely. The protest thus far has been described as “largely peaceful” by a police spokesman.

On Saturday, an estimated thousand or more people attempted to protest in Paternoster Square, the site of the London Stock Exchange, but were blocked by police enforcing a High Court judgment. Julian Assange from Wikileaks also joined the protest to address the activists. A flag flies over the occupation showing the ‘Anonymous’ logo of a headless man in a black suit.

At around 9:30am Wednesday, many campers were still asleep, but around 30–50 people were listening in solidarity to trade union representatives from the National Shop Stewards Network, while 20 to 30 officers from the City of London police watched on. On the steps of St. Paul’s Cathedral, the speakers spoke about a variety of struggles including strikes by electricians that started in August against Balfour Beatty, one of Britain’s largest construction firms. Solidarity was expressed with the travellers at Dale Farm, and speakers described how the media and others were trying to “divide” workers, students and elderly people. One of the speakers said that while today they are occupying the square in London, “tomorrow we will be occupying universities and colleges” and spoke of the suspension of Vik Chechi, the Unison branch secretary who has been suspended by Queen Mary University. By 9:45am, the trade union talks had finished and the sound system was reactivated and reggae music started playing.

After the talks peter out, activity begins to resume on the site: people sorting out tents and serving food, under signs and banners playfully mixing politics (“The London Stock Exchange: Britain’s Biggest Casino”) with Internet memes (a Reddit cartoon man depicted saying “Y U NO JOIN US?”).

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.

At 1:30 a.m. on Thursday morning the United States Senate voted to include the repeal of the Affordable Care Act, better known as Obamacare, as part of a budget blueprint. This procedural measure allows most of Obamacare to be repealed by a simple majority rather than the usual requirement of 60 out of the senate’s 100 votes and effectively prevents the use of filibuster.

“We’re working with legislative leaders at this very moment to begin to craft legislation that will repeal the most corrosive elements of Obamacare — the individual mandate, the taxes, the penalties — but at the same time, moving separate legislation that will allow us to introduce the kind of reforms in American health care that’ll lower the cost of health insurance without growing the size of government,” said Vice President-elect Mike Pence.

Democratic Senator Maria Cantwell of Washington had a different view, going so far as to call this “stealing health care from Americans.”

The filibuster is a last-ditch tactic in which parties opposed to a certain motion refuse to relinquish the floor until their opponents give in or compromise.

Although the 51-48 vote was mostly along party lines, some Republicans have expressed uncertainty about repealing Obamacare before a replacement system is worked out. Although president-elect Donald Trump has called for a “repeal and replace” plan, saying that a new health care system would be enacted “almost simultaneously,” many in government and the press have expressed doubts about whether this would actually happen.

Senator Susan Collins of Maine said she would like to at least see a well-constructed plan before voting and Senator Johnny Isakson of Georgia said repealing Obamacare without replacing it was “unacceptable.” These concerns were shared by members of the House of Representatives. “We need to be voting for a replacement plan at the same time that we vote for repeal,” added Representative Mark Meadows of North Carolina. Representative Tom MacArthur of New Jersey agreed, saying, “We’re loading a gun here. I want to know where it’s pointed before we start the process.”

Anna Merlan of Jezebel and Anthony Taylor of the Associated Press dismiss Trump’s timeline as “impossible” given the complicated nature of U.S. congressional workings. Senator Collins agreed, saying “I don’t see any possibility of our being able to come up with a comprehensive reform bill that would replace Obamacare by the end of this month. I just don’t see that as being feasible.”

The Affordable Care Act, which is often cited as a key accomplishment of the Obama administration, has had a mixed reputation, and many conservatives believe a market-based health care system would be more flexible and efficient and less costly, and many believe that the Affordable Care Act only passed because of Obama’s later discredited pledge that no one who liked their current health plan would have to switch. Matt O’Brien of The Washington Post claims a large tax cut that would result for the wealthiest 1% of citizens if Obamacare funds were not converted to other purposes, estimated at about $32,820 annually per person by the Tax Policy Center, is also a significant motive.

Republican Senators set a date of January 27 to repeal Obamacare, according to NBC News. House Majority Leader Kevin McCarthy of California says legislation repealing Obamacare and replacing it could ready by late February. According to Democratic Senator Bernie Sanders, as many as 30 million people could lose their health insurance if the ACA is repealed.

Saturday, January 29, 2005 With just days to go before Sunday’s historic poll to choose a new government in Iraq, UN Secretary General Kofi Annan has invited the people of Iraq to exercise their democratic rights.

The poll, the first free elections in a generation, faces disruption from insurgents who are totally opposed to democracy. Annan warned them not to interfere and promised continuing help from the UN for the country in the future.

Annan made his appeal in a pre-recorded message, broadcast on TV inside Iraq. “Elections are the best way to determine any country’s future; please exercise your democratic rights on Sunday,” he said. “Whatever your feelings about how the country reached this point, this election offers an opportunity to move away from violence and uncertainty toward peace and representative government.”

The UN has been providing advice and technical help to the Independent Electoral Commission of Iraq (IECI), as well as $100m funding for the poll and co-ordination of international assistance. A team of 40 experts has overseen the delivery of three million tonnes of election materials and helped the IECI and Iraqi officials prepare and maintain the voters register.
