New Canadian guidelines for losing weightPosted:January 26, 2015
The Canadian Task Force on Preventive Health Care has issued its latest guidelines on adult obesity prevention and management. Adult obesity in Canada has nearly tripled in the past 40 years. Today 67% of men and 54% of women are considered overweight or obese making adult obesity one of Canada’s most pressing public health challenges. Among other things the new guidelines recommend life-style changes over diet drugs such as orlistat or metformin. Experts note that a weight reduction of even 5% is beneficial and can extend life expectancy.
How much fossil fuel can we exploit?Posted:January 7, 2015
Canada would need to leave 75 per cent of its oil in the ground as part of a global effort to cap global warming at two degrees Celsius above pre-industrial levels, a new study shows. The authors also conclude that the exploitation of resources in the Arctic should be ruled out. Using computer models, the authors found that if current global fossil fuel reserves are burned as planned, that will result in CO2 levels on Earth about three times higher than the +2 degree C level predicted by IPCC models.

Honey bees fight backPosted:September 27, 2012
The parasitic mite Varroa destructor is a major contributor to the recent mysterious death of honey bee (Apis mellifera) colonies. New Canadian research published in BioMed Central's open access journal Genome Biology finds that specific proteins, released by damaged larvae and in the antennae of adult honey bees, can drive behavior that promotes improved hive hygiene. Dr Leonard Foster at the University of British Columbia, who led this research says, "Bee keepers have previously focused on selecting bees with traits such as enhanced honey production, gentleness and winter survival. We have found a set of proteins which could be used to select colonies on their ability to resist Varroa mite infestation and can be used to find individuals with increased hygienic behavior. Given the increasing resistance of Varroa to available drugs this would provide a natural way of ensuring honey farming and potentially survival of the species."
Canadian science advocacy group takes on homeopathyPosted:August 2, 2012

Saskatoon scientist achieves malaria cure breakthroughPosted:March 24, 2011
Today's best anti-malaria drug is artemisinin, a compound derived from the sweet wormwood plant (Artemisia annua) from Asia and Africa. But extracting artemisinin directly from the plant is difficult and only small quantities are obtainable. Patrick Covello, a senior researcher at the National Research Council in Saskatoon has found a number of genes in the sweet wormwood plant that code for the enzymes involved in the most difficult part of the synthesis of the rather complicated artemisinin molecule. Those genes have now been incorporated into a yeast by a Berkeley, California drug company so that the drug can be produced inexpensively and in quantity by the yeast. This could lead to a cheap and easily available cure for malaria, a disease which kills millions of people every year. Visit Dr. Covello's lab website to learn more.
Experts feel Japanese nuclear reactor fallout will not reach CanadaPosted:March 17, 2011
One of the most reliable websites for updates about conditions at Japan's damaged Fukushima nuclear reactor is the International Atomic Energy Agency in Vienna, Austria. Their website with current status and news is continually being updated. Canadian nuclear engineering experts such as Greg Evans, a professor in the department of chemical engineering and applied chemistry at the University of Toronto, do not think that Canada is in any danger. Most of the lethal radioactive materials ought to be contained by systems on the reactor site, even if there is a meltdown, and anything that escapes would dissipate over the vast area of the Pacific ocean before reaching Canada. However, for those concerned, there are a number of online resources. Radiolab in Arizona provides a constantly updated map of background radiation levels from online geiger counters in cities around North America including Vancouver, Canada. Blackcat systems in Westminster, Maryland provides a similar Online Geiger Counter Nuclear Radiation Detector Map with a station in the Rocky Mountains in British Columbia.

Crocodile tears don't fool us allPosted:February 9, 2011
How easy is it to fake remorse? Not so easy if your audience knows what to look for. In the first investigation of the nature of true and false remorse, Leanne Brinke and colleagues from the Centre for the Advancement of Psychology and Law (CAPSL), University of British Columbia (in the Okanagan) and Memorial University of Newfoundland, show that those who fake remorse demonstrate a greater range of emotional expressions and swing from one emotion to another very quickly - a phenomenon referred to as emotional turbulence - as well as speak with more hesitation. These findings have important implications for judges and parole board members, who look for genuine remorse when they make their sentencing and release decisions. Brinke's work is published in Springer's journal Law and Human Behavior.

En bloquant cette molécule, Smith a réussi à encourager le repoussement du nerf optique chez des souris adultes aveugles. Il reste à voir si la repoussement du nerf optique va restaurer la vue, mais ces repousses restaurer la vue dans les aveugles bébés souris. Smith est né en Jamaïque et est arrivé au Canada à titre d'immigrant pauvre. Dans un article du Globe and Mail dit-elle, "je ne suis pas issu d'un milieu de privilège. Mais si vous voulez faire quelque chose, vous pouvez le faire." Plus d'information sur Smith et sa découverte est disponible au service de nouvelles de l'Université Carleton.

Yeast-powered fuel cell feeds on human bloodPosted:April 1, 2009
A team at the University of British Columbia in Vancouver, Canada, has created tiny microbial fuel cells by encapsulating yeast cells in a flexible capsule. The fuel cells can generate power from a drop of human blood plasma. The team is led by Mu Chiao professor of mechanical engineering. The yeast-based fuel cell produces around 40 nanowatts of power, compared to the microwatt a typical wristwatch battery might produce, Chaio says. That might be enough power for some devices if it were coupled with a capacitor to allow energy to be stored. The yeast could also be genetically engineered to boost its power output.

Save $1 billion and 800 livesPosted: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.

New Canadian robot arm added to space stationPosted: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 sciencePosted: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 PhDsPosted: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 Team First in Space Elevator ContestPosted: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 impactPosted: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.

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 TeamPosted: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 DepressionPosted:July 28, 2006

H. S. M. (Donald) Coxeter died March 31, 2003 at the age of 96. Known as the "Greatest Living Classical Geometer", Coxeter was a huge contributor to the area of mathematics known as "plane geometry"--something he took to the highest levels. Learn more about Coxeter.
Canadian Gets Antibiotics From MosquitoesPosted:March 18, 2003
Simon Fraser University biologist Carl Lowenberger wants to know why mosquitoes don't get sick from the infectious diseases they carry. He has isolated several immune system molecules (peptides) from mosquitoes that protect them from harmful pathogens. Perhaps these molecules can become the basis for improved antibiotic drugs for humans. More at Lowenberger's homepage.
Canadian Space Shuttle ExperimentsPosted:January 17, 2003
Two Canadian experiments are flying aboard space shuttle mission STS-107: the OSTEO-2 bone loss experiment conducted by Toronto scientists Leticia G. Rao, Tim Murray and others; and an experiment by teams in Quebec, Ontario and Saskatchewan on growing protein crystals that could help fight cancer and diabetes.
Canadian Research Revises Meteor SciencePosted:December 2, 2002
Earth's upper atmosphere is hit once a year by objects that release energy equivalent to a five kiloton bomb, a Canadian meteor physicist,Peter Brown, of the University of Western Ontario claimed in a recent Nature article. Brown bases his findings on data from US Department of Defense satellites scanning the Earth for evidence of nuclear explosions.
Canada Creates Large Virtual SupercomputerPosted:November 2, 2002
A team of computer scientists at the University of Alberta have developed CISS (Canadian Internetworked Scientific Supercomputer), the software and social infrastructure for a Canada-wide metacomputer. CISS open source software will go nationwide November 4, 2002 to attack a chemistry problem involving the energies of chirality or "right or left handedness" of molecules. This problem which would normally take 3 - 6 years of computing time should complete in one day on CISS. While software is a major component, Paul Lu, a CISS researcher says, "Much more time and arm-twisting has been spent to convince people to include their systems in CISS. We accept, and are trying to work with, human nature. Technologists ignore human factors at their own peril."
Canada's Space TelescopePosted:August 2, 2002
UBC astronomer Jaymie Matthews says Canada's first space telescope contains "the most accurate light meter in the world." The telescope should be able to "see" into distant stars and to detect the light from possible planets orbiting them. The telescope was extremely cheap to build, costing 300 times less than the Hubble telescope. It will be launched in April 2003 atop a Russian rocket. Matthews hopes the Canadian telescope will confirm or disprove the existence of other planets which so far can only be inferred from the wobble of some stars.
Canadian offers natural solution to spruce budworm problemPosted:May 12, 2002
Carleton University researcher Dr. J. David Miller believes that a family of needle-loving fungi holds the key to stopping the 10 to 15 year cycle of destruction wreaked by the spruce budworm, Choristoneura fumiferana, on Canadian and American forests. Miller discovered that older, natural (not-replanted) forests harbour a "good" anti-budworm toxin-producing fungus. He has found a way to safely innoculate seedlings with it.
Canada's Sharing Attitude Attracts Top ScientistsPosted:April 10, 2002
Leading neurologist David Colman will move himself and his research team of 15 researchers from New York to Montreal where he will become the director of the Montreal Neurological Institute at McGill. Colman's stated major reason for the move: "In the States, the individual scientist is stressed, and that creates a system where everyone grabs, and no one is encouraged to share. In Canada, there is a lot more collaboration and sharing."
Canada Underinvests in SciencePosted:March 12, 2002
A study by Save British Science, now known as the Campaign for Science and Engineering claims that, of the G7 nation governments, only Canada and Italy invest less in research and development per capita than the UK. Canada invests only 0.21% of its Gross Domestic Product in research. The report also claims Canadian businesses spend US$358 per worker on research and development compared to Americans who spend US$1065 per worker.
Canadian Scientists Go Faster Than the Speed of LightPosted:February 2, 2002
Physicists, Alain HachÃ© and Louis Poirier, at the University of Moncton, using what they call a "coaxial photonic crystal" have managed to send electromagnetic pulses a significant distance at three times the speed of light. The remarkable project breaks no laws of physics. In essence, they use cavitation at the tail of the pulse to drive the front wave forward. The result could exert a profound influence on information networking systems. PhysicsWeb has the story.
Canadians begin catalogue of human proteomePosted:January 11, 2002
Now that scientists have worked out the human genome, the next task is to figure out the human proteome, the total set of proteins the genome encodes. Researchers at the University of Toronto are using supercomputers to do it. In this week's Nature, working with colleagues in Heidelberg, Germany, Canadian geneticists led by Mike Tyers and Michael Moran use a supercomputer to unravel the highly complex interaction of the thousands of proteins coded in the genome of yeast. Their key finding: each protein is involved in numerous interactions and therefore new designer drugs targeted to specific proteins could have serious side effects. Visit Tyer's Lab website to get an idea of the complexity involved.
Canadian Scientists Question National Security ID SchemesPosted:December 11, 2001
Canadian computer scientists Andrew Clement (U of T) and Felix Stalder (Queens) claim on a website sponsored by Computer Professionals for Social Responsibility that none of the recently proposed national identification schemes spawned by the events of Sept 11 clearly state which problem they try to solve and how exactly they would contribute to reducing the danger of terrorism. The scientists point out that such ID systems do endanger our civil liberties. Even more, by relying on the wrong approach to security, the new measures may actually create a false sense of security that leaves us more vulnerable than before.
Vancouver bio tech firm to supply US militaryPosted:December 4, 2001
A Canadian biotechnology firm is working with the U.S. Army to develop a nasal spray vaccine that would protect against plague.
ID Biomedical will help ward off the threat of "Black Death" as a bioterrorist weapon.
The Vancouver company's proteosome vaccine technology causes protective immune responses at the mucosal surfaces lining the respiratory tract, including the nose, throat and lungs.
Parasite genome stripped to bare essentialsPosted:November 23, 2001
"This is an exciting time for parasitology," says Patrick J. Keeling of the University of British Columbia, in a News and Views article in this week's Nature magazine refering to the discovery by French researchers that the parasitic microsporidion Encephalitozoon cuniculi has a genome less than 0.1% the size of the human genome and is even smaller than the genomes of many bacteria. Its genes have little ‘junk’ DNA between them. This has nearly erased the genomic record of the organism's evolutionary history, making it difficult to determine how it originated. According to Keeling, other emerging genome sequences will "usher in an age of comparative parasite genomics." If E. cuniculi is an indication, he concludes, "many ‘rules’ are about to be broken."

Male garter snakes mimic females to get warmPosted:November 15, 2001
Australian scientists studying Canadian garter snakes (Thamnophis sirtalis parietalis) suggest in this week's Nature magazine that slow and sleepy male garter snakes might mimic females to fool other males into warming them up. These 'she-males' produce female pheromones at the end of hibernation, causing them to become engulfed in large 'mating balls' of amorous males — sometimes containing more than 100 snakes.
Canadian scientist explains source of ocean colourPosted:November 4, 2001
"The single most important independent factor responsible for the colour of the open ocean is free-floating, microscopic phytoplankton," says Shubha Sathyendranath, an expert in underwater optics and current head of Remote Sensing and Marine Optics at the Plymouth Marine Laboratory (PML). Sathyendranath is the first person to use satellites to map diatom distribution in the North Atlantic.
Science Teachers Association of Ontario ConferencePosted:September 9, 2001

Canadians Solve Missing Neutrino MysteryPosted:July 19, 2001
The 30-year-old "Missing Solar Neutrino Mystery" has been solved in Canada. The first, long-awaited, scientific results from the Sudbury Neutrino Observatory were released in early July 2001. These results offered the first direct and definitive proof that electron-neutrinos produced in the sun's core undergo transformations into muon- and tau-neutrinos en route to the earth. See the details at www.sno.phy.queensu.ca.
