"Adults who ate canned soup daily showed a jump in levels of the plasticizer BPA in their urine, according to a small study. The study of 75 people in Tuesday's issue of the Journal of the American Medical Association is one of the first to quantify BPA levels in humans after eating canned foods compared with eating freshly prepared ingredients. Bisphenol A is an industrial chemical used to make polycarbonate plastic for water bottles and food containers as well as the protective lining in metal cans."

"Fauja Singh, 100, finished Toronto's waterfront marathon Sunday evening, securing his place in Guinness World Records as the oldest person - and the first centenarian - to ever accomplish a run of that distance."

"A report released late Thursday in London and discussed Friday at the U.N. climate conference in South Africa said that - in theory - reflecting a small amount of sunlight back into space before it strike's the Earth's surface would have an immediate and dramatic effect. Within a few years, global temperatures would return to levels of 250 years ago, before the industrial revolution began dumping carbon dioxide into the air, trapping heat and causing temperatures to rise."

"A dizzying array of research suggests alcohol can have both good and bad effects, but making sense of such studies all comes down to who you are and how much you drink. That point was driven across Tuesday with the release of a U.S. study suggesting women who consume three to six alcoholic beverages a week face a small increased risk of breast cancer, but it's not enough of a danger to stop drinking. The study in the Journal of the American Medical Association involved 105,986 nurses who were tracked for three decades."

"Building scientists have known for a long time that glass-walled structures are less energy efficient than the stone and concrete buildings that were put up forty of fifty years ago. But the market demand for glass combined with the relatively low cost of glass-wall construction means the building industry has been happy to oblige."

Throw-away Buildings Thermal Window Failure: How it Happens Virtually all glass condominium towers feature window wall systems (floor-to-ceiling walls of glass) enclosing the entire facade. Window walls yield spectacular views, but owners who buy a condo unit for the view may not realize that they're relying on a couple of panes of glass separated by less than an inch of insulated space to protect them from the elements. That insulated barrier will degrade over time, even as energy costs increase. On some buildings, five per cent of the thermal windows may have failed before they're even delivered to the construction site. Another 10 - 15 per cent will fail by the 20-year mark as they're exposed to the physics of heat expansion. By the 25 year-mark, a growing number will fail every year.

"One transport truck-sized asteroid passed the Earth Wednesday morning and another will soar by in the afternoon, with both far closer to the planet than the moon. There is no danger of the Earth being hit and both should be visible with moderate-sized amateur telescopes, NASA reported."

"The two developed a technique that uses bacteria to break down the foam plastic used in many disposable cups, fast-food containers and packing materials."

"Lack of aerobic fitness may impair how the heart copes with the stress of running a marathon, Larose and his colleagues said. "This is not a permanent injury that will leave any type of scar," said Larose, a professor of medicine at Laval University at Quebec City."

""National surveys in both the United States and Canada indicate that most people receive enough calcium, with the exception of girls ages nine to 18, who often do not take in enough calcium," Tuesday's report reads. "In contrast, post-menopausal women taking supplements may be getting too much calcium, thereby increasing their risk for kidney stones.""

Physics of curling probed for Olympic team Jenkyn is studying the physics of curling using an infrared camera as part of the Canada's $22-million Own the Podium research program into sport"

Canadian scientist Willard S. Boyle received the Nobel for physics Thursday, a prize he's sharing with two other physicists honoured for their work in optics.

"Canadians are consuming more fresh fruits and vegetables and cutting calories, a report by Statistics Canada shows."

"Canadians are not fully informed about these risks and may not be taking appropriate precautions to protect themselves," the report says. It's not that Ottawa hasn't identified toxins. In 2006, the government compiled a list of more than 4,300 toxic substances it was evaluating."

Murray and Becky Monk yearned for the best of both worlds: life in the breathtaking wilds of northwestern Ontario and the conveniences of modern life. They turned their wish into reality by moving to the solitude of a remote lake and setting up their own eco-friendly power system.

"The problem is that a proposed ban might include thiomersal, a mercury compound used to prevent contamination and extend the shelf life of vaccines, many scientists say. It is used in about 300 million shots worldwide, against diseases including flu, tetanus, hepatitis B, diphtheria and meningitis. "Not being able to use mercury is not a viable option," said David Wood, a WHO vaccines expert."

"Exposure to BPA before birth could affect girls' behavior at age three, according to the latest study on potential health effects of the widespread chemical. Preschool-aged girls whose mothers had relatively high urine levels of bisphenol-A during pregnancy scored worse but still within a normal range on behavior measures including anxiety and hyperactivity than other young girls."

"A new study on cellphone safety has found that carrying a phone in a shirt or pants pocket exceeds radiation exposure guidelines spelled out by the the Federal Communications Commission (FCC), and that children absorb twice as much cellphone radiation as adults. The study published in the journal Electromagnetic Biology and Medicine criticizes the way phone manufacturers measure levels of microwave radiation, and calls for the industry standard to be scrapped."

"Initial estimates pegged the number of dead waterfowl as high as 6,000, but Cooper said ministry staff were going to do an updated assessment on Monday. Tests were being done to determine the cause of the deaths, but previous such die-offs often were caused by the waterfowl eating botulism-laced fish, Cooper said."
