Dogs are normally resistant to most flu strains. Since about 2000, a new strain of dog flu has been spreading in America, and there’s no vaccine to prevent it.

To limit exposure to the flu, some dog owners are avoiding public places like dog shows and parks. Since the flu can spread where groups of dogs are housed, some dog owners are nervous about the practice of putting their pets in kennels. According to Edward Dubovil, director of the animal virology lab at Cornell University, 100% of dogs appear to be susceptible to infection by this new flu strain. It is estimated that 1-5% of infected dogs are dying from this flu strain. The symptoms of dog flu are akin to those of kennel cough, a more common and less serious illness.

Starting in 2004 there have been many outbreaks of flu at dog race tracks. Since early in 2004, researchers have been working to characterize the type of flu that is infecting dogs. In September of 2005 it was reported that this dog flu strain had crossed over from horses to dogs. This type of flu virus has been infecting horses for at least 40 years. It is expected that existing flu vaccines for horses can soon be adapted for use in dogs.

The spread of a horse flu virus to dogs is an example of what could happen with bird flu. Currently the bird flu is transmitted from birds to humans but does not spread easily from person to person. The new strain of dog flu shows signs of having been genetically modified from the original horse-preferring virus strain making it easy to transmit from dog to dog. Future genetic modifications of bird flu could better adapt it to humans and allow it to spread from person to person. The chance of such viral evolution can be reduced by limiting exposure of humans to bird flu.

At this time, the new dog flu virus strain does not seem to be a danger for humans. However, humans will be monitored for signs of infection by new genetic variants of the dog flu. Due to the close physical association between pet dogs and humans, a flu strain that could jump from dogs to humans would be of great concern. Recently evolved virus strains that jump from one species to another are often particularly lethal because the newly infected species may have little or no immunity to the new virus strain.

Protestors in Greece, rallying against austerity measures, have clashed with police in the capital of Athens.

Some people participating in the rally — attended by thousands of teachers and students — threw stones at riot police, who responded by employing pepper spray, although the BBC described the protests as being generally peaceful. Demonstrators say that a recent austerity proposal, which is to include pension cuts and an increase in taxes, will adversely affect the education sector.

Teachers, along with hospital workers and public servants, have started a two-day strike over the measures. Also present were 150 members of the armed forces, who protested having their bonuses lowered.

Meanwhile, earlier on Tuesday, approximately a hundred demonstrators with the Communist Party broke through locks at the Acropolis and hung up banners saying: “Peoples of Europe — Rise Up”.

Communist Member of Parliament Nikos Papaconstantinou commented: “We want to send a message to the farthest reaches of Greece and Europe. Similar measures that eliminate social security are taken across Europe. But popular anger will rattle imperialist organisations.”

The austerity plan comes shortly after the Greek government said it would introduce spending cuts to obtain a loan package by the EU and International Monetary Fund, aimed at helping Greece recover from a financial crisis.

Britain’s Ministry of Defence (MoD) has admitted sixteen instances of sensitive information being leaked on social networking websites in the past eighteen months. Ten employees have been disciplined for misuse of the sites. The revelations follow a Freedom of Information request by Lewis PR and computer security company F-Secure.

The MoD would not comment on what disciplinary action was taken, or whether the leaks involved operational information. The ministry’s guidelines state that staff must obtain clearance to release any information that is related to sensitive, controversial or political matters, or military operations.

“It’s worrying that employees in sensitive positions have been sharing confidential information via Twitter and other means,” said Mikko Hypponen, of F-Secure. “Loose Tweets can cost lives.”

According to Lewis PR, computers on the main MoD networks are blocked from visiting social networking sites. However there are a small number within the department which have unrestricted Internet access. Some personnel in Afghanistan and Iraq also have access through internet cafés on military bases.

The ministry’s “online engagement guidelines”, released in August last year, recognise the importance of social media such as Facebook for personnel keeping in touch with friends and family. According to the document: “Service and MOD civilian personnel are encouraged to talk about what they do, but within certain limits to protect security, reputation and privacy.”

Poison control centers across the US are monitoring a recent increase in the trend of teenagers getting drunk by consuming hand sanitizer. In an effort to educate the public about the trend’s detrimental effects, these centers will be publicizing preventative methods, according to James Mowry, director of Indiana Poison Center.

“We are going to keep a close watch on this trend,” said Mowry. “We will be posting information on our Facebook page so our public will be aware of what could happen.”

Sixteen cases have been reported in California since March 1, according to the California Poison Control System. This amount raises California’s total to 60 cases reported since 2010.

Since the system “only receives the reported cases,” said Stuart E. Heard, executive director at CPCS, “… we suspect there are much more that go unreported.”

Ingesting the product can cause severe internal damage. The US Food and Drug Administration considers hand sanitizer a drug because the active ingredient in the product is alcohol. Low numbers of reported cases will not stop poison control centers from educating the public on the trend’s harmful effects, according to Mowry.

Hand sanitizer contains 62 percent ethyl alcohol and, when ingested, produces the same effects of consuming a 120-proof alcoholic beverage or 50 percent more alcohol than hard liquor, according to Mowry. These effects range from dizziness to slurred speech. Ingesting the product can also lead to severe internal damage including alcohol poisoning. Alcohol poisoning symptoms include confusion, vomiting, seizures, slow or irregular breathing, blue-tinged or pale skin, low body temperature, and unconsciousness, according to a report from the American Association of Poison Control Centers.

“Teens may ingest hand sanitizer recreationally, and one or two swallows could get a child visibly drunk. The larger the bottle, the greater the potential for poisoning,” said Cyrus Rangan, a medical toxicology consultant at the Children’s Hospital Los Angeles and an assistant medical director at CPCS.

Teenagers learn how to extract the alcohol from the product through various sources, like YouTube tutorials. A common method of distilling hand sanitizer involves using salt to isolate the alcohol. Other teens boil the product to separate the ethanol.

“Methods to distill it can be found through friends and the Internet, but straight ingestion of the product without distillation is also common,” said Rangan. Another concern with this trend is the product’s availability. “Hand sanitizer is readily available,“ said Heard. “Teens can buy it anywhere.”

Officials suggest parents keep hand sanitizer out of children’s sight and reach. Also, purchasing hand sanitizer in foam form instead of gel makes drinking the substance less appealing. However, education is critical. “The main preventative focus should be education,” said Heard. “Teens need to thoroughly understand the effects of consuming large amounts of alcohol in a short amount of time.”

Three of Sweden’s ten nuclear reactors have been shut down due to safety concerns following an incident last week at the Forsmark Nuclear Power Plant, in which the reactor cooling systems failed. The reactor has since been shut down there. After the incident, the Swedish Nuclear Power Inspectorate, SKI asked all the nuclear power plants to demonstrate that the same failure could not happen in them. On Wednesday, two more reactors at Oskarshamn were shut down after the operator said their safety could not be guaranteed.

Last week’s incident at the Forsmark plant was triggered by a short circuit that cut power to the reactor cooling system. Two of the four backup generators also failed to start, but the remaining two worked and were sufficient to meet the plant’s needs. Greenpeace reports that the fault in the backup power systems were traced to new equipment installed in 1993.

The spokesman of the Swedish Nuclear Power Inspectorate Anders Bredfell denied that there was any danger of a meltdown, adding that there was also a backup gas turbine to power the cooling system in an emergency.

However, Lars-Olov Höglund, who was responsible for the nuclear plant Forsmark for many years, said the incident was the most dangerous one since Chernobyl and Three Mile island, and that a meltdown was avoided only by pure luck. His views have however been questioned as he is involved in litigation with the Swedish nuclear industry and is known as an outspoken nuclear critic. Researchers at the Royal Institute of Technology as well as the personnel at the power plant were critical of Höglunds’ view.

Speaking to BBC News, SKI spokesman Anders Bredfell said that the International Atomic Energy Agency (IAEA) was informed of the incident as required and that the incident classes as a ‘2’ in the 0-7 scale used by the IAEA to assess the severity of the incident.

Another reactor in Forsmark and a fifth at Ringhals nuclear power plant have been offline due to planned maintenance work. With five of its ten reactors down, Sweden’s power generation capacity is down by almost a fifth.

The environmental group Greenpeace called on the government to shut down all reactors and probe whether the fault was a generic one. The Green Party has called for an independent investigation of the incident. Sweden is scheduled to retire all its nuclear power plants in the next few decades, as decided by a referendum in 1980.

Anyone planning on attending the 2008 Summer Olympic Games in Beijing, China can forget about renting a car when they get there.

Newspapers reported on September 18 that no private cars would be allowed near any of the venues in the host city, in an attempt to combat the gridlock that has plagued the city.

Known for its stand-still traffic, Beijing’s transport authority believes it needs to curb at least 20% of traffic flow to ensure the Games run smoothly. The number of cars in the city is set to increase from 2.7 million to 3 million by the time of the Olympics. Country-wide, annual car sales are expected to reach 10 million annually by 2010.

A good infrastructure is one of the International Olympic Committee’s top priorities when searching for bid cities. The IOC requires that athletes, support staff such as coaches, venue volunteers, spectators, and the press all should be able to get from venue to venue without hassle.

Existing plans in Beijing say that private cars may only drive in the city on alternate days. Plates with odd numbers would drive one day, while even numbered licenses would drive the next day.

Wired magazine has suggested fuel-cell vehicles may be China’s next cultural revolution. Vancouver-based venture capitalist Mike Brown told the National Post: “If they get aggressive about this, and they decided to build up a fuel cell manufacturing capability to sell half a million of these things, they’ll get the costs down faster than anybody else.”
