Local municipal and provincial volunteers in Manitoba, Canada are exhausted in their efforts to divert the rising waters of the Red River of the North.

It has been hard work with little sleep for the residents who live on the shores of the Red River to shore up their defences with sandbags, build dikes, clear frozen culverts and break ice jams

Volunteers to spell relief for local volunteers and food are desperately needed.

“It’s a week now we’ve been doing this … you’re talking four, five, six public works guys. In my one community we’ve got 25 volunteer firefighters and those guys have been going 24/7, so of course it’s wearing them down.” said Paul Guyader, Manitoba’s emergency measures coordinator.

“We’re dealing with one of the biggest floods the province has ever seen,” said Steve Strang, mayor of St. Clements, Manitoba “We’ve put out hundreds of thousands of bags already. The municipalities are working very well, we’re working with the provincial government, we’ve brought in every possible resource we could to address this issue. The volunteerism within the community has been phenomenal.”

The Portage Diversion has taken some spring waters from the Assiniboine River and diverted the flow to Lake Manitoba.

Roseau River Anishinabe First Nation has been totally evacuated, as well as many homes near the Canada – United States border.

The cold weather is freezing the ice jams into place. Guyader has had 2 Amphibex Excavators operating on the river breaking up ice.

The Red River is right now 16.7 feet (5 metres) above spring ice conditions. The Red River Floodway gates cannot be opened with the current ice jams.

“If we operate now, we can get ice jamming going into the floodway, jamming up against the St. Mary’s bridge, as such, the floodway capacity would be reduced and would cause higher water levels in the city of Winnipeg.” said Steve Topping, Manitoba Water Stewardship spokesman

The floodway was constructed in 1968 following the 1950 flood to divert the overflow spring flooding waters of the Red River. The floodway has been widened the since the 1997 “flood of the century” and the expansion is expected to be completed this spring. As well Manitoba built permanent dikes around communities within the flood plain since the last two major floods..

The Red River waters will crest between the beginning of April to mid April, at which time also the weather should be warming up. Communities are bracing for higher water levels, more ice jams as well as melting snow in the warmer spring temperatures.

Bovine spongiform encephalopathy, better known as BSE or “mad cow” disease, may have been caused by human remains ingested by British cattle, two scientists said today.

Alan Colchester and his daughter Nancy Colchester, from the University of Kent and University of Edinburgh, respectively, suggested that the remains of humans cast into the Ganges in an Indian funeral rite contaminated Indian animal feed that was imported to the U.K. If some of the humans died of Creutzfeldt-Jakob disease, bone meal infected with CJD would have entered the British food chain, causing the similar BSE in cattle.

Admitting the evidence was not solid, the two scientists still argued that this new theory merited further review. The current theory of the origin of BSE involves the transmission of scrapie, a similar disease that affects sheep, to cattle. Prions, infectious proteins that would be the only disease-causing agents without nucleic acid, are thought to be the cause of all of these diseases.

Scientists at NASA have recently released the most detailed map of Antarctica ever. NASA’s Landsat 7 satellite took 10,000 photographs of the continent over a period of two years, from 1999 to 2001. 1,100 pictures were chosen to form the mosaic map. Officially titled the Landsat Image Mosaic of Antarctica (LIMA), the map reveals Antarctica’s geography in high definition and with accurate colors. Details as small as half the size of a basketball court are visible.

NASA created the map to coincide with the International Polar Year of 2007-2008. Robert Bindschadler, chief scientist of the Hydrospheric and Biospheric Sciences Laboratory at NASA’s Goddard Space Flight Center, remarked, “This innovation is like watching high-definition TV in living color versus watching the picture on a grainy black-and-white television.” The map represents a tenfold improvement over previous Antarctic imagery databases.

Landsat 7 managed to capture 80% of the continent in high definition. While the satellite was not able to take photographs of the South Pole due to its orbit path, lower-resolution images helped fill in the gap.

The map will help scientists plan and carry out expeditions on the notoriously difficult terrain. The new, intensely detailed information will also facilitate the tracking of environmental changes such as the calving of ice shelves. Researchers will be able to use such data to better understand phenomena like global warming in such amazing detail that even relatively small changes will be visible. Geologists, on the other hand, will be able to use the maps to study Antarctic rock formations.

The LIMA images are available to the public via the internet. The National Science Foundation contributed nearly US$1 million to create the website.

The Landsat 7 satellite will continue to document Antarctica from space through to 2011. Subsequently, NASA will launch the Landsat Data Continuity Mission. Information from both projects will update the map.

Tuesday, March 29, 2005A team of Australian surgeons yesterday reattached both hands and one foot to 10-year-old Perth boy, Terry Vo, after a brick wall which collapsed during a game of basketball fell on him, severing the limbs. The wall gave way while Terry performed a slam-dunk, during a game at a friend’s birthday party.

The boy was today awake and smiling, still in some pain but in good spirits and expected to make a full recovery, according to plastic surgeon, Mr Robert Love.

“What we have is parts that are very much alive so the reattached limbs are certainly pink, well perfused and are indeed moving,” Mr Love told reporters today.

“The fact that he is moving his fingers, and of course when he wakes up he will move both fingers and toes, is not a surprise,” Mr Love had said yesterday.

“The question is more the sensory return that he will get in the hand itself and the fine movements he will have in the fingers and the toes, and that will come with time, hopefully. We will assess that over the next 18 months to two years.

“I’m sure that he’ll enjoy a game of basketball in the future.”

The weight and force of the collapse, and the sharp brick edges, resulted in the three limbs being cut through about 7cm above the wrists and ankle.

Terry’s father Tan said of his only child, the injuries were terrible, “I was scared to look at him, a horrible thing.”

The hands and foot were placed in an ice-filled Esky and rushed to hospital with the boy, where three teams of medical experts were assembled, and he was given a blood transfusion after experiencing massive blood loss. Eight hours of complex micro-surgery on Saturday night were followed by a further two hours of skin grafts yesterday.

“What he will lose because it was such a large zone of traumatised skin and muscle and so on, he will lose some of the skin so he’ll certainly require lots of further surgery regardless of whether the skin survives,” said Mr Love said today.

The boy was kept unconscious under anaesthetic between the two procedures. In an interview yesterday, Mr Love explained why:

“He could have actually been woken up the next day. Because we were intending to take him back to theatre for a second look, to look at the traumatised skin flaps, to close more of his wounds and to do split skin grafting, it was felt the best thing to do would be to keep him stable and to keep him anaesthetised.”

Professor Wayne Morrison, director of the respected Bernard O’Brien Institute of Microsurgery and head of plastic and hand surgery at Melbourne’s St Vincent’s Hospital, said he believed the operation to be a world first.

According to the Japanese Defense Ministry, North Korea has fired a short-range missile today into the Sea of Japan. Officials believed it to be part of a regular exercise.

“North Korea fired a short-range missile in what appeared to be part of a military drill,” a Japanese Defense Ministry official was quoted as saying by Yonhap News Agency.

A South Korean defense spokesman said such tests are routine.

“We don’t deny that North Korea fired a missile,” South Korean Army Colonel Ha Doo-chul, told Yonhap. “If it did, we regard it as a routine exercise.”

The test comes at the time when North Korea is inviting inspectors in to discuss its nuclear programs.

VIENNA –Doctors from the Rudolfinerhaus clinic in Vienna say “there is no doubt” Ukrainian opposition leader Victor Yushchenko was poisoned with Dioxin.

Yushchenko’s body had about 1,000 times more than the normal concentration of the toxin. It is unknown if there were any other poisons in his system.

Although it has not yet been proven that the poisoning was deliberate, doctors suspect it was. “We suspect a cause triggered by a third party,” said Michael Zimpfer, head doctor at the Rudolfinerhaus clinic. He suggested the poison may have been administered orally, through food or drink.

Today’s announcements are a follow-up of an earlier press conference, where Dr. Korpan that there were three hypotheses under consideration, one of them involving dioxin. He did not reveal what the other two hypotheses were. Dr. Michael Zimpfer, director of the Rudolfinerhaus clinic emphasized that time there was no proof yet to specify the substance causing the illness.

Yushchenko left Kiev on Friday (2004-10-12) for further examination in Vienna. When Yushchenko fell ill on October 6th, Ukrainian doctors had initially diagnosed food poisoning, leading to speculation that he had been poisoned deliberately. The illness has disfigured Yushchenko’s body and face which doctors say could take up to two years to heal.

He fell seriously ill on the September 6th, during his presidential campaign. Yushchenko was taken to the Rudolfinerhaus clinic of Vienna, where he stayed for four days under Dr. Korpan’s care. He was diagnosed with “acute pancreatitis, accompanied by interstitial edematous changes.” These symptoms were said to be due to “a serious viral infection and chemical substances which are not normally found in food products” as his campaign officials put it. In laymans terms, he developed an infection in the pancreas and got a bad skin condition that disfigured his face with cysts and lesions. The skin condition has similarities with the chloracne associated with dioxin posioning according to a British toxicologist John Henry.

Earlier, doctor Nikolai Korpan of Rudolfinerhaus clinic confirmed today that the illness of Ukrainian presidential candidate Viktor Yushchenko was caused by an attempt to kill him.
