NASA data show Arctic saw fastest August sea ice retreat on record Posted: September 26, 2008
Following a record-breaking season of arctic sea ice decline in 2007, NASA scientists have kept a close watch on the 2008 melt season. Although the melt season did not break the record for ice loss, NASA data are showing that for a four-week period in August 2008, sea ice melted faster during that period than ever before.
When healing turns to scarring: Research reveals why it happens and how to stop it Posted: September 18, 2008
For the first time, research from The University of Western Ontario has revealed the mechanisms involved in the origin of scarring or fibrotic diseases, as well as a way to control it. The study, led by Andrew Leask of the CIHR Group in Skeletal Development and Remodeling, is published in the Journal of Clinical Investigation.
Canadian Scientists find first pregnant turtle fossil and eggs Posted: August 27, 2008
A 75-million-year-old fossil of a pregnant turtle and a nest of fossilized eggs that were discovered in the badlands of southeastern Alberta by scientists and staff from the University of Calgary and the Royal Tyrrell Museum of Palaeontology are yielding new ideas on the evolution of egg-laying and reproduction in turtles and tortoises. It is the first time the fossil of a pregnant turtle has been found and the description of this discovery was published today in the British journal Biology Letters. The mother carrying the eggs was found near Medicine Hat in 1999 by Tyrrell staff while the nest of eggs was discovered in 2005 by U of Calgary scientist Darla Zelenitsky.
Mucous breakthrough in mice holds promise for cystic fibrosis Posted: July 29, 2008
A London, Canada scientist studying cystic fibrosis (CF) has successfully corrected the defect which causes the overproduction of intestinal mucous in mice. This discovery by Dr. Richard Rozmahel, a scientist with the Lawson Health Research Institute, affiliated with The University of Western Ontario, has clear implications to understanding and treating this facet of the disease in humans. CF is a fatal, genetic disease characterized by an overproduction of mucous in the lungs and digestive system. More about CF on our page about Lap Chee Tsui.
Researchers find key to saving the world's lakes Posted: July 21, 2008
After completing one of the longest running experiments ever done on a lake, researchers from the University of Alberta, University of Minnesota and the Freshwater Institute, contend that nitrogen control, in which the European Union and many other jurisdictions around the world are investing millions of dollars, is not effective and in fact, may actually increase the problem of cultural eutrophication. It turns out that phosphate may be more likely to cause the problem. Visit the Experimental Lakes Area website, where the research took place.
In unique stellar laboratory, Einstein's theory passes strict, new test Posted: July 3, 2008

Save $1 billion and 800 lives Posted: June 11, 2008
The economic burden of alcohol abuse costs each Canadian $463 per year. In fact, the direct health care costs for alcohol abuse in Canada exceed those of cancer. Released today by the Centre for Addiction and Mental Health (CAMH), the Avoidable Cost of Alcohol Abuse in Canada 2002 report estimates that, even under very conservative assumptions, implementing six reviewed interventions would result in cost savings of about $1 billion per year and a savings of about 800 lives, close to 26,000 years of life lost to premature death and more than 88,000 acute care hospital days in Canada per year. This pioneering study is Canada's first systematic estimate of the avoidable costs of alcohol abuse, and the first study of its kind worldwide.

On Sunday, May 4, 2008, a symposium will be held to honour Erich Vogt at UBC's Hebb Theatre, featuring talks by Physics Nobel Laureates and leaders in Canadian science & technology, with a reception to follow. Vogt is one of the giants of Canadian science, having served as (among other things) a founder and later Director of the TRIUMF accelerator laboratory, as UBC's Vice President for Faculty and Student Affairs and as the first chair of the Science Council of B.C. Vogt played a leading role in the development of Science World BC, the Vancouver Institute and the B.C. Cancer Foundation. However, perhaps his greatest contribution was four decades of teaching first year Physics to enthralled students at UBC. For more information about Erich Vogt and his achievements, visit the TRIUMF website.
New Canadian robot arm added to space station Posted: March 18, 2008
Astronauts on the space shuttle Endeavor have completed the assembly of a giant Canadian robot arm called Dextre outside the International Space Station. They attached a 1.5 m metal boom to its front for holding equipment and tools. The robot’s 3 m arms will be used for experiments and for maintenance of the space station. The astronauts added a holder for three tools under the 3,400-pound robot’s right arm and a pan-and-tilt color camera on its body so operators can observe its work. The $209 million robot, which has passed initial operating tests, will be attached to the station’s Destiny laboratory module. More at the Wikipedia entry on Dextre.
Canada criticized internationally for disregarding science Posted: February 22, 2008
A February 2008 edition of the journal Nature has criticized Canada's Conservative government's "manifest disregard for science". They cite the government's recent closure of the office of national science adviser. The office used to offer advice on global science and technology issues and how government can better fund and support Canadian science. In addition, the Conservative government recently decreed that Environment Canada scientists must route all media enquiries through Ottawa for an "approved" response so the government could control the position of Canadian science of global climate change. Finally, the Conservative government cabinet failed to attend a reception for Nobel Prize winning Canadian scientists last week in Ottawa. If you want to express your concern for our country's poor international image regarding Canadian science, and the way this has come about due to Conservative government actions and policies, please write your MP by looking up the address on the government's contact page, or write the Prime Minister directly, or Jim Prentice the minister of Industry who is now responsible for science research funding.
Stats Canada points to benefits of science PhDs Posted: November 23, 2007
According to Macleans Magazine, Science and engineering PhDs were, in 2001, nearly twice as likely to work in the private sector as PhD holders from other disciplines, and only 38 per cent of them worked in educational services, compared to 60 per cent of PhD holders in other fields. The Statistics Canada report also looked at location. Ninety per cent of scientists and engineers live in urban areas. The highest concentration is in Kingston, dubbed the â€œscience and engineering capital of Canada,â€ with its two universities, a college, and teaching hospital. The concentration of scientists and engineers employed by the federal government also played a role as Ottawa-Hull came in second. Scientists and engineers living in Vancouver earned the highest average salary in Canada at $89,179, while the lowest was found in Edmonton at $73,527. Men with science PhDs outnumber women four to one.
Canadian study finds weight-loss pills not worth the risk Posted: November 21, 2007
University of Alberta medical researchers reviewed 30 studies of weight loss pills such as orlistat, sibutramine and rimonabant and found that on average they help users shed only 3-5Kg. What's more the side effects are not worth the risk. The research was led by Dr. Rajdeep Padwal in the Department of Medicine at the U of Alberta.
Canadian Team First in Space Elevator Contest Posted: October 21, 2007
A team of students and alumni from the University of Saskatchewan have again provided the winning robotic climber for this year's Elevator:2010 Competition in Utah (October 19 and 20, 2007). This is the second consecutive year the team's climber outperformed all others. The Space Elevator is a system based on a super-strong ribbon going from the surface of the Earth to a point beyond geosynchronous orbit. The tether is held in place by a counterweight in orbit. And so, as the Earth rotates, the tether is held taut. Vehicles would then climb the ribbon powered by a beam of energy projected from the surface of the Earth. Such a space elevator is not possible today, but researchers around the world are working on the technologies that will be required. The Canadian contribution from USask is a method of powering the elevator with a beam of light projected by lasers on the ground. Visit www.usst.ca for more information including a video.
Canadian science has tremendous world impact Posted: August 14, 2007
In a May 2007 report, Thompson Scientific, a company that tracks refereed scientific publications and the citations they contain, gave Canada a glowing report. With little more than 0.5% of the world’s population Canada produces 4.65% of the world's scientific publications.
Citations are references in formal scientific research papers that refer to previously published research. If such research is cited frequently by other scientists it generally means it contained a valuable discovery that was influential. Based on citations collected between 2002 and 2006, on average Canadian research is cited 7% more than research from the rest of the world. In 21 of the 22 scientific fields tracked (excepting economics & business), the impact of Canadian research met or exceeded the world average, with particularly strong performance in space science (57% above the world average), clinical medicine (34% above), and physics (+31%). These findings are reported on Thompson's inCites website.
In another 2005 review, Thompson shows that among the 145 top-performing countries in all fields, Canada ranked #6 for citations, #6 for papers, and #16 for citations per paper. Canada leads the world in the following fields in terms of volume published as well as impact based on citation indexes: Psychology, Geosciences, Ecology/Environment, Economics, Education, Space Science, Clinical medicine, and Physics.

New way to find ice-loving bacteria Posted: October 13, 2006
A Canadian scientist at Queens University has developed a way to isolate bacteria that survive in extreme cold. Virginia Walker, a professor of biology and President of the Genetics Society of Canada uses microscopic "ice fingers" to isolate bacteria which have properties to interact with, and modify, ice. The bacteria have many potential applications from improving the consistency of ice-cream to the creation of better snow making machines. Read more at the Queens News Centre.
Canadian Software Proves What Neil Armstrong Said Posted: September 30, 2006
Peter Shann Ford, a Sydney, Australia-based computer programmer used Canadian sound editing software called GoldWave (from St. John's, Newfoundland) to analyse the first words of Apollo astronaut Neil Armstrong when he set foot on the moon. According to the research, he said, "That's one small step for a man, one giant leap for mankind." Not "That's one small step for man, one giant leap for mankind. NOTE: The science of this news story has since come under heavy criticism. Hence the result may not be true.
Canadian Astronaut to Work on Space Station Posted: September 10, 2006
Canadian astronaut Steve MacLean is set to make a spacewalk after he successfully rocketed to orbit aboard space shuttle Atlantis Sept. 9, 2006. MacLean, on his second spaceflight, joins five other astronauts on the first construction mission to the International Space Station since the Columbia disaster of 2003. The Nepean, ON native will play a crucial role in increasing the station's power. Using the robotic Canadarm, he will manoeuvre a set of solar panels from the shuttle to the station. He will then perform a spacewalk on Sept. 13 to release locks on the panels, allowing them to track the sun. (Elizabeth Howell reporting)
Faintest Stars Detected by Canadian Led Team Posted: August 18, 2006
Astronomer Harvey Richer at the University of British Columbia used the Hubble telescope to study white dwarfs in star cluster NGC 6397, which is 8500 light years away. The light detected is the equivalent of a birthday candle on the moon.
Astronomers have used white dwarfs in globular clusters as a measure of the universe's age. The universe must be at least as old as the oldest stars. White dwarfs cool down at a predictable rate. The older the dwarf, the cooler it is, making it a perfect "clock" that has been ticking for almost as long as the universe has existed. Richer and his team are using the same age-dating technique to calculate the cluster's age. NGC 6397 is estimated to be nearly 12 billion years old.
Canadian Scientists Discover Gene for Depression Posted: July 28, 2006
Canadian scientists have identified a gene that makes some people susceptible to major depressive disorders. Speaking at the Forum of European Neuroscience earlier this month, Professor Nicholas Barden of Centre Hospitalier de l'UniversitÃ© Laval in Quebec explained, â€œThis is a major breakthrough in the realm of psychiatry and will have groundbreaking implications for diagnosis and the development of new anti-depressant treatment.â€
Canadian Scientists Develop Drug to Stop Alzheimer\'s Posted: June 14, 2006
University of Toronto researchers led by Joanne McLaurin at the Centre for Research in Neurodegenerative Diseases have found a small sugar molecule called scyllo-cyclohexanehexol (AZD-103) associated with Alzheimer's disease. In mice with Alzheimer's disease the drug prevents the formation of amyloid plaques thereby preventing further cognitive damage and memory loss. It does not reverse existing damage. Human trials have been approved and will begin later this year.
Canadian Helps to Learn Cause of Pioneer Anomaly Posted: June 11, 2006
Pioneer space crafts 10 and 11 were launched about 30 years ago. Now as they reach the very edge of our solar system they appear to be moving somewhat slower than expected. What is causing this Pioneer Anomaly? Nobody knows, but a Canadian freelance scientist in Ottawa, Viktor Toth, has written software to analyse vast amounts of telemetry archived over the years, to make it available to the public. It is hoped that the availability of the data will help solve the mystery.

Common antidepressents may affect the immune system Posted: January 27, 2006
A team of Canadian and US researchers co-lead by Dr. Peta O'Connell at the Robarts Research Institute in London, Ontario have found that SSRI drugs like Prozac, Zoloft, and Paxil that treat depression may also affect the user’s immune system.
It appears that serotonin is passed between key cells in the immune system, and that the chemical is specifically used to activate an immune response. Researchers do not know yet if the effect will be beneficial or a damaging to the human immune system. Read more about this research from an article on the Robarts website.
