It has been confirmed that tests done on a dead Mute Swan found in the village of Cellardyke in Fife, Scotland has tested positive for the deadly strain of H5N1 Bird Flu virus. The swan is believed to have been native to Scotland.

Two other swans found in Richmond Park in Glasgow are being tested for the H5N1 virus. They are among at least 14 other dead birds and 12 more swans found in Glasgow, that are being tested for the H5N1 virus.

This is the United Kingdom‘s first confirmed case of the H5N1 virus and would make the U.K. the 14th country to report the virus.

“The risk to humans has not changed by the fact that we have found the virus in the U.K.. There is a better chance of a person winning the national lottery than catching bird flu in the U.K. today,” said Doctor Jim Robertson from the National Institutes for Biological Standards and Control in a press conference.

“We also have to work on the assumption that there is some spread among wild birds. There is no doubt we are getting closer to the day when moving birds indoors will be necessary,” said former President of the British Veterinary Association, Bob McCracken. “The situation is that the virus is there, and it will probably continue to circulate among the birds. It will spread through close contact, irrespective of species. There is one big question mark: Will the virus disappear from wild birds after a period of six months, or will it still be present after a period of six years?” added McCracken.

McCracken also said that the virus could turn up in more birds saying, “I would start from the assumption that a small pool of wild birds in the Fife area are infected and potentially passing it on to other birds” and that seagulls could pose a threat of passing on the virus because they have been known to peck at the bodies of other dead birds that were infected. “We have to assume that,” he said.

In a statement by the Department for Environment, Food and Rural Affairs, released yesterday, the Scottish Executive confirmed that a “highly pathogenic H5 avian flu” virus was found in a sample taken from the dead swan.

The swan was discovered March 29, 2006 and has been confirmed as a domestic species and officials say that it may have caught the virus from another infected bird. Officials also report that the area where the swan has been found is being sealed off.

“In accordance with a recent EU decision the Scottish Executive is putting in place a protection zone of a minimum of three kilometres radius and a surveillance zone of 10 kilometers. Keepers of birds in the protection zone are being instructed to isolate their birds from wild birds, by taking them indoors where ever possible,” said the Scottish Executive in a statement.

Samples from the swan were sent to the European Union Bird Flu Laboratory at Weybridge.

“Bird keepers outside the protection zone should redouble their efforts to prepare for bringing their birds indoors if that becomes necessary. They must also review their biosecurity measures to ensure that all possible precautions have been taken,” said Charles Milne, Chief Veterinary Officer for Scotland yesterday in the statement.

An exercise named ‘Exercise Hawthorn’ was to prepare people for a possible pandemic was taking place yesterday and was halted just after the discovery of the dead swan. Officials were in the second phase of the exercise. Taking part in the exercises were the Ministry of Defence, the Association of Chief Police Officers, the Environment Agency and several other areas of the British government.

“I brought to an end the national avian influenza exercise to ensure that we can bring all our resources to bear on this situation. We are already in a high state of readiness and I have every confidence that officials north and south of the border will work together to manage this incident successfully,” said the United Kingdom’s Chief Veterinary Officer, Debby Reynolds.

However; today Reynolds stated “there is no reason for public health concern” and also stated that in order for Bird Flu to infect humans, it would require “extremely close contact with infected birds, particularly feces.”

According to the World Health Organization H5N1 has killed 109 people worldwide since 2003.

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”.

A Finnish study has indicated that having higher body levels of lycopene — a red chemical occurring in tomatoes, watermelons, grapefruit, peppers, and papaya — may reduce the risk of stroke. The research for the study, which is in the issue of medical journal Neurology released today, examined 1,031 men aged between 42 and 61 over a period of twelve years on average.

The study, which was financed by the Lapland Central Hospital, found that the men with higher amounts of lycopene in their blood system experienced fewer strokes than men with lower levels. Eleven strokes occurred amongst the 259 men in the highest of the four lycopene level categories while 25 of the 258 men in the categories with the lowest lycopene level categories experienced strokes. This suggests a stroke was 55% less likely if one had a high amount of the chemical in one’s diet than if one had a low amount.

“The results support the recommendation that people get more than five servings of fruits and vegetables a day,” said Dr Jouni Karppi of the Department of Medicine at the University of Eastern Finland. Eating these types of foods in such quantities “would likely lead to a major reduction in the number of strokes worldwide, according to previous research”, the primary author of the study continued. He added that inflammation and blood clotting — the cause of ischemic strokes, the most common type of stroke — occurred less frequently.

In the US state of New York, Lenox Hill Hospital Center for Stroke and Neuro-Endovascular Surgery director Dr. Rafael Ortiz said that, alongside exercise and non-smoking, “diet is very important” for reducing the likelihood of stroke. However, these results “should not deter people from eating other types of fruit and vegetables as they all have health benefits and remain an important part of a staple diet”, according to Dr Clare Walton of The Stroke Association in the UK.

The results came as part of a wider study on cardiovascular disease development risks. The United States Department of Agriculture also registers high concentrations of lycopene in tomato purées, pastes and sauces. All those surveyed lived in, or in close proximity to, the Finnish town of Kuopio, where the University of Eastern Finland is located.

The family of murdered UK thirteen-year-old Milly Dowler, whose phone was hacked by journalists of the News of the World, have been offered £3 million compensation by Rupert Murdoch’s News International, in settlement negotiations currently under way.

UK newspaper The Guardian revealed the phone hacking earlier this year. After Dowler was reported missing in 2002, her voicemail messages were listened to and several deleted, creating the impression she might still be alive.

The £3 million on offer reportedly includes £1 million to charity. The rest would go directly to the family. The Guardian reports the Dowler’s lawyers were believed to be looking for about ?3.5 million.

News International stated they were “in advanced negotiations” and “hope to conclude the discussion as quickly as possible.”

Rupert Murdoch personally met with the Dowler family earlier in the year to offer them his apologies for the actions of his News of the World paper. News of the World ceased publishing after discovery of the Dowler hacking and other similar incidents.
