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.

Dr. Tewolde Berhan Gebre Egziabher, the Ethiopian government’s chief scientist and its representative to the Montreal-based UN Convention on Biological Diversity (CBD) had his passport returned without the requested Canadian visa, and without explanation. Dr. Tewolde is Africa’s chief negotiator for the Cartagena Protocol on Biosafety.

Tewolde had announced he would be visiting Montreal the first week of August to lobby for the labeling of genetically modified (GM) seeds and food products and urge companies and governments to accept liability for environmental contamination their seeds could lead to. Canada has yet to ratify the UN biosafety protocol and opposes compulsory genetically modified labeling and liability.

Dr. Tewolde has worked against terminator technology (genetically-modified seed rendered sterile at harvest time, forcing farmers to buy new seeds each growing season). In the past, Dr. Tewolde has disagreed with Canadian scientists on proposed methods to regulate GM products.

“Dr. Tewolde is one of the most respected scientists in his field,” said Pat Mooney, representative for the conservationist ETC Group in Ottawa, “If the Canadian government can’t make sure Dr. Tewolde has his visa for the opening of the meetings, Canada does not deserve to host the Convention on Biological Diversity.”

Dr. Tewolde himself is concerned that Canada’s actions signal a pattern, “Now that I have been prevented from coming to Montreal, who knows which ones of you will be prevented next time?” he wrote.

This closely mirrors another more recent incident where 12 Ugandans (mainly youths) were denied visas by the Canadian High Commission in Kenya. After making two applications and having met all the requirements asked by the commission, the Ugandan delegation was still denied visas.

Six-year-old Thomas David Horne from the United Kingdom has died and eleven other British tourists were injured Friday when their plane crashed in Canaima National Park in Venezuela. They were on a sight seeing tour of the world’s tallest waterfalls, the Angel Falls.

The single engine, nine-seater Cessna 208 Caravan, lifted off shortly before the end of the runway, lost power, and then surged briefly before plummeting into the Venezuelan jungle in front of the 3,200 ft falls.

“It started to take off and we sensed it was losing power. Then it seemed to get it back and lifted off just 200 metres before the end of the runway. Then it dived into the trees,” reported Makeli Freire, a park tour guide.

Three of the injured sustained serious injuries, while the others suffered mainly broken bones. Thomas Horne, who sustained serious head injuries, died on the way to a local hospital. The pilot, co-pilot and tour guide were among the injured. Everyone on board was flown to Ciudad Bolívar, the capital city of Venezuela’s Bolívar state, where they were treated for their injuries. Among the injured were Thomas’s mother and father Jane and David who were among those who had broken bones. They were British tourists finishing up a two week holiday to Venezuela.

“The young boy died as he was being flown to hospital. His parents are both physically OK but are completely distraught over the loss of their son,” said Maiker Puga, of the Ciudad Bolivar clinic.

Liz and her husband Keith Grainger and S. Phillips, also British tourists, were also injured in the crash. The names of the three other British tourists and the three person crew who were injured have not been released at this time.

The plane tour was offered by First Choice, a division of TUI Travel PLC who extended their “heartfelt sympathy to family and friends during this deeply sad time.” LTA airline has suspended further flights until the investigation is concluded.

June Holman, Thomas’s aunt who was not on holidays said, that “there is nothing worse than losing a loved one, especially not a young child with their whole life ahead of them. The thoughts of us all are with his parents Jane and Dave at this very sad time.”

0 A.D. is a historical, open source, strategy game, published by Wildfire Games. It focuses on the period between 500BC and 500AD. The game will be released in two parts: the first covering the pre-AD period, and the second running to 500AD. With development well underway, Wikinews interviewed the development team.

Aviv Sharon, a 24-year-old Israeli student responsible for the project’s PR, compiled the below Q&A, which the full team approved prior to publication.
