The nuclear reactor at Chalk River, Ontario in Canada was shut down on Thursday, May 14 by the Atomic Energy of Canada Limited (AECL) due to a leak of heavy water. Government officials say that by Saturday the demand for medical isotopes will no longer be met, due to the shortage caused by the closure.

Medical isotopes are used in diagnostic procedures for cancer, heart disease and other medical conditions. When radioactive isotopes are injected into the body, radiologists can view higher radiation via medical imaging, enabling them to make a more accurate diagnosis.

Estimates suggest that the reactor will be shut down for approximately one month for repairs. The Chalk River Laboratories produce 33% of the international supply of medical isotopes.

Lisa Raitt, Natural Resources Minister said, “A secure supply of medical isotopes is not only an issue for Canada, it is an international issue that is being addressed co-operatively by all isotope-producing countries.”

“It may mean that if you have an elective study booked … that patient is going to be deferred and will have to wait until the situation is resolved. I’m reasonably confident that for most patients, if they’re having an acute problem, that problem is going to be dealt with – and the greater the acuity, the more likelihood it’s going to be dealt with quickly and expeditiously,” said Dr. Karen Gulenchyn, a nuclear medicine expert.

“The government of Canada is engaging international isotope producers as well as companies such as MDS Nordion, Lantheus, and Covidien, who all play key roles in securing medical isotope supply for North America,” said Raitt and Health Minister Leona Aglukkaq.

In December 2007, the 52-year-old reactor was shut down and the Canadian House of Common stepped in to restart the reactor.

Dogs can be trained to detect early and late stages of lung and breast cancer accurately according to a study published by California scientists in the little-known scientific journal Integrative Cancer Therapies.

The study took place over the last five years at the Pine Street Foundation, a non-profit organization which conducts evidence-based research on integrative medicine (combining complementary and alternative medicine and mainstream medicine). Michael McCulloch and colleagues used three Labrador Retrievers and two Portuguese Water Dogs, both common pets, that received basic behavioral dog training. The researchers trained the dogs to lie down next to a sample from a cancer patient and to ignore other samples.

The samples used were breath samples from 55 patients with lung cancer and 31 with breast cancer — the two types of cancer with the highest mortality rates in the United States.

After the training phase, the dogs’ accuracy diagnosis was tested in a double-blind experiment. Among lung cancer patients, the sensitivity and specificity were 99% accurate and for breast cancer sensitivity was 88% and specificity 98%. Because these figures seem almost too good to be true, cancer experts are the same time baffled and skeptical. The authors of the study themselves also say replication of the study is needed.

Importantly, this was independent of the cancer stage, meaning the dogs were able to pick up the scent of cancer in its early stages. This is important because in many cases, the success of any treatment depends on early diagnosis. However, the researchers don’t believe this will lead to the use of dogs in the clinic soon, rather they want to find out which chemicals are actually sensed by the canines, because they could be used in laboratory assays. “It’s not like someone would start chemotherapy based on a dog test,” Dr. Gansler of the American Cancer Society said, “They’d still get a biopsy.”.

The researchers were inspired by anecdotal reports about dogs detecting cancer. In 1989, a British women consulted with her family physician because her Dalmatian kept licking a mole on her leg. At biopsy it showed to be malignant melanoma. When diagnosed too late this form of cancer has a poor survival rate, but in this case early surgery was made possible, and the women survived. Prior studies showed that breath samples from patients with lung cancer or breast cancer contain distinct biochemical markers. This provides a basis for the hypothesis that some cancer types produce volatile chemicals that dogs could smell. A study published in the British Medical Journal already proved that dogs could use their exquisite sense of smell to detect bladder cancer in urine samples, but they were only correct in 41% of cases, and another study provided preliminary evidence that dogs could detect melanomas.

This doesn’t mean you can show your breasts to your dog and it will tell you if you have cancer, other physicians caution, and scientists do not advise people to train their dogs to sniff for cancer. Unresolved issues from the study include the fact that subjects were required to breathe deeper than normal, so it’s not sure whether dogs can smell cancer in normal breath. Also, whether this is a permanent skill that would be retained by dogs was not tested.

Finally, there are concerns that could arise over liability issues: who would be responsible when the dog makes a mistake?

Current detection methods for both lung and breast cancer are not flawless. For lung cancer, chest X-ray and sputum cytology (detecting cancer cells in coughed up fluid) fail to detect many early cases, and CT scan produces many false-positive results unless combined with expensive PET scans. Although it might be comparing apples and oranges, a $2.5 million CT scanner has an accuracy of 85 to 90%. Mammography also produces false-positive results, and it may be difficult in women with dense breast tissue. As such, another type of “pet”-scan, using dogs as a biological assay, might prove feasible for screening if supported by further research. Current tests are also expensive so the use of dogs for preliminary cancer testing could prove to be an affordable alternative for countries in the developing world.

The Conservative Party of Canada leader Stephen Harper today made bold claims about the Canadian Arctic region at a campaign stop in Winnipeg, “The single most important duty of the federal government is to protect and defend our national sovereignty.” . The prime minister-hopeful stated, “There are new and disturbing reports of American nuclear submarines passing though Canadian waters without obtaining the permission of —or even notifying — the Canadian government.”

Harper promised a significant increase in military presence in the Canadian region, which has had notable soveriegnty disputes with the United States, Russia, Denmark and Norway.”You don’t defend national sovereignty with flags,” Harper said. “You need forces on the ground, ships in the sea, and proper surveillance.”

Among other promises, Harper stated he would station three armed naval heavy ice breakers in the area of Iqaluit with 500 regular force personnel, recruit 500 more Canadian rangers, and build a new army training center in the area of Cambridge Bay on the Northwest Passage.File:Stephen Harper voa.jpg

“As prime minister, I will make it clear to foreign governments — including the United States — that naval vessels traveling in Canadian territorial waters will require the consent of the government of Canada,” Harper stated.

The Conservative Party Website states this ““Canada First” Northern Strategy will increase surveillance, navy, army and air force presence”.

The Liberal Party of Canada, the Conservatives’ most powerful rival in the election, quickly posted a rebuttal on their website. They claim Stephen Harpers stated defense budget of $5.3(CAD) billion over 5 years is not enough to afford the two polar icebreakers, which the Liberal party claims will cost $3(CAD) billion with the party estimating an upkeep of $150(CAD) million per year. “Where does Mr. Harper plan to find another $1 billion?” the party asked in their rebuttal.

The Arctic may be an important issue in the future for Canadians, as scientists expect the fabled Northwest Passage of the Arctic to open up for year round shipping by 2050 as a result of global warming. According to the online encyclopedia Wikipedia, trade routes from Europe to the Far East could save 4000 km through the passage, as compared to the current routes through the Panama Canal.

Canada last flexed its muscle in the Arctic in 2004 in its most massive Arctic exercise ever, with six hundred personnel from the three services (army, air force, navy) involved in a large exercise in the Baffin Islands.

Canadians are scheduled to go to the polls on January 23, 2006 in an early election as a result of a non-confidence motion in parliament against the former ruling Liberal party.

Alaskan U.S. Senator Ted Stevens, who turned 85 yesterday, narrowly lost his re-election bid to Mark Begich, the Democratic Mayor of Anchorage, Alaska.

Meanwhile, as Alaska’s counting of the November 4 election is almost complete, Democratic challenger for the US House of Representatives, Ethan Berkowitz, conceded to incumbent Don Young, the Republican Party nominee.

With this result, the Democrats are two seats away (assuming that independents Bernie Sanders and Joe Lieberman continue to caucus with them) from a filibuster-proof supermajority in the United States Senate, with two races (Minnesota and Georgia) as yet uncalled. That would allow the Democrats to invoke cloture, limiting filibusters to a further 30 hours, an ability last attained in the 95th Congress of 1977-79.

Stevens is entitled to request a recount at his campaign’s expense, and has not yet made a statement. After the completion of counting yesterday, Begich had defeated Stevens by 3,724 votes, a margin of over one percent. 2,500 special absentee and postal ballots remain to be counted on November 25.

Begich released a statement on his win saying, “I am humbled and honored to serve Alaska in the United States Senate. It’s been an incredible journey getting to this point, and I appreciate the support and commitment of the thousands of Alaskans who have brought us to this day.”

Young won his race by 16,280 votes, a margin of five percent.

Stevens recently became a convicted felon on seven counts for lying on Senate disclosure forms about accepting $250,000 in gifts and home renovations from VECO, an oil services company. He has asked President George W. Bush not to grant him a presidential pardon.

From March 15 to 17, the Canadian city of Toronto played host to the tenth Furnal Equinox, an annual event dedicated to the “furry fandom.” Wikinews attended. Programming ranged from music to gender, science to art, covering dozens of aspects of the varied subculture. The event’s featured guests were visual artists Moth Monarch and Cat-Monk Shiro, as well as the co-owners of US fursuit costume builders Don’t Hug Cacti.

The event raised nearly CDN$11,000 for Pet Patrol, a non-profit rescue organization in Kitchener-Waterloo, Ontario, run by volunteers. This exceeded their goal of $10,000, the funds needed to finish a rural sanctuary. The furry community is well-known for their charitable efforts. Along with direct donations, the funds were raised through a charity auction offering original artwork, and a fursuit design by guests of honour “Don’t Hug Cacti.” Last year, Furnal Equinox raised funds for a farm animal sanctuary.

While only 10–15% of people within the fandom own a fursuit according to a 2011 study, event organizers reported this year 908 of the 2240 attendees at Furnal Equinox brought at least one elaborate outfit to the event. The outfits are usually based on original characters, known as “fursonas”.

Guests of Honour Cherie and Sean O’Donnell, known within the community as “Lucky and Skuff Coyote”, held a session on fursuit construction on Saturday afternoon. The married couple are among the most prominent builders in the fandom, under the name Don’t Hug Cacti. The scale of their business was evident, as Sean had made over a thousand pairs of “handpaws”, costume gloves.

The couple encouraged attendees to continue developing their technique, sharing that all professional fursuit makers had developed different techniques. They felt that they learned more from failed projects than successful ones, citing the Chuck Jones quote that “every artist has thousands of bad drawings,” and that you have to work through them to achieve. Cherie, known as Lucky, recalled receiving a Sylvester the Cat plush toy from a Six Flags theme park at age 10. She promptly hollowed the toy out, turning it into a costume. Creating a costume isn’t without its hazards: the company uses 450°F (232°C) glue guns. They’re “like sticking your hand in an oven.”

Other programming included improv comedy, dances, life drawing of fursuiters, a review of scientific research by a research group at four universities called FurScience, a pin collector’s social, and workshops in writing.

The “Dealer’s Den” hall was expanded this year, with even more retailers and artists. While many offered “furry” versions of traditional products, at least one business focused on “pushing the boundaries of fursuit technology.” Along with 3D printing a bone-shaped name tag when Wikinews visited, Grivik was demonstrating miniature computer screens that could be used as “eyes” for a fursuit. The electronic displays projected an animation of eyes looking around, blinking occasionally. The maker has also developed “a way to install a camera inside suit heads, to improve fursuiter visibility.” He hopes the tech would reduce suiting risks and accidents. Without the need for eyeholes, fursuit makers would have “more options for building different eyestyles.”

In early May, Wikinews extended an invitation to Vitaly Filipchenko, an independent candidate in the 2021 New York City mayoral election, set to take place November 2nd, alongside other candidates. Filipchenko answered some questions about his policies and campaign during a phone interview.

Filipchenko, registered on the New York City Campaign Finance Board as Vitaly A. Filipchenko, is the first Russian candidate for New York City mayor, being born in Tomsk, Siberia in 1973, according to news agency Sputnik. He has since naturalised as a United States citizen. According to the web site, Filipchenko has been educated in road construction and maintenance and owns a moving services company; he describes himself on his web site as a “small business owner”. On his web site’s platform page, he says that “[m]y English may not be perfect – but my platform is.”

Incumbent Democrat mayor Bill de Blasio, who won re-election in the 2017 New York City mayoral election by 66.5%, cannot run for a third term under term limits. As of April 28, 22 candidates are currently running, the majority of whom are also Democrats. Ahead of the June Democratic primary for New York City mayor, a poll conducted May 23 and 24 by WPIX and Emerson College of 12 Democratic candidates with a margin of error of 3.2 per cent has former commissioner for the New York City Department of Sanitation Kathryn Garcia and Borough President of Brooklyn Eric Adams leading with 21.1% and 20.1%, respectively.

First Active has become the first financial institution to offer 100% mortgages in the Republic of Ireland. The bank previously offered 100% financing to professionals in finance and medicine, but is now to offer this product to anyone who can afford to meet the repayments.

The development is a huge boost for first time home buyers who have been struggling to get on the Irish property market in recent years due to the rapid increase in house prices. A typical first time buyer in Dublin with 92% financing would normally have to put down a deposit of €20,000-€30,000 in cash, but now have the option to produce no deposit.

First Active has said that 100% mortgages will be available across its entire range of mortgage products.

Note however that this is not necessarily an entirely positive development.

The United States and most of Europe have experienced a housing price bubble in recent years. A bubble occurs when buyers purchase a property not because its price is appropriate for its actual value but because they expect the price to significantly rise in the short term permitting resale with a profit.

In other words, the prices people pay for properties becomes divorced from the real value of the property; the purchase is speculative and depends purely upon the expectation that people will continue to buy properties in this way (e.g. without proper consideration of their real value).

The terrible weakness in this is that when the market corrects itself and prices fall to a level where properties are being priced at their actual realistic value, anyone holding a property loses a great deal of money, since the price they paid does not reflect the actual realistic value of the property.

This kind of shock to the housing market is extremely undesirable. Significant write downs in the value of property often significantly depress the economy as a whole.

Less than 100% mortgages force buyers to invest a significant amount of money in the act of purchasing their house, which tends to discourage purely speculative purchasing, thus helping to mediate house price bubbles.

With 100% financing, anyone who can meet repayments can speculatively purchase a property. This naturally encourages pricing bubbles.
