CMAJ calls on federal government to protect Canadians from unsafe drugs Posted: April 18, 2011
Canadians are poorly protected from potential side effects of new drugs and food additives due to our ancient federal Food and Drugs Act that has changed little since 1953. Repeated attempts since 1995 to effect change have been thwarted. An editorial in CMAJ (Canadian Medical Association Journal) explains.
Saskatoon scientist achieves malaria cure breakthrough Posted: 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 Canada Posted: 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.
E-health must be a priority, researchers say Posted: March 8, 2011
The Canada Health Infoway project was implemented by the federal government in 2001 with the goal of accelerating e-health implementation and creating a national system of interoperable electronic health records. After 10 years and $1.6 billion of investment in 280 health information technology projects, Canada still lags behind countries such as Denmark, the UK, and New Zealand. These are the findings of a new study assessing the effectiveness Canada Health Infoway's e-health plan conducted by scientists at the Research Institute of the McGill University Health Centre published today in the Canadian Medical Association Journal.
Crocodile tears don't fool us all Posted: 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.
Canadian researchers link music to dopamine release in brain Posted: January 18, 2011

MÃ©thode dÃ©couverte pour rÃ©parer les nerfs adultes endommagÃ©s Posted: December 11, 2009
Le scientifique canadien Patrice Smith à l'Université Carleton à Ottawa a trouvé un moyen d'obtenir des cellules nerveuses adultes à se développer chez les souris. Son article dans la revue Neuron cette semaine avec les co-auteurs Sun Fang et Zhigang de L'université de Harvard, il décrit la découverte d'une molécule spécifique dans le système nerveux central qui supprime notre capacité à réparer les neurones blessés. 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 blood Posted: 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.
