Stats Canada study verifies difference in male/female interest in science Posted: December 18, 2013
A study released today demonstrates how Canadian women prefer to choose non-science and non-mathematics related university courses even if they have a propensity for math in high-school. The study was based on the 2011 National Household Survey as well as a long-term Youth in Transition study that followed students from 2000 - 2010. Even if women have high mathematics aptitute they are twice as likely to choose to study the social sciences rather than engineering and computer science. Read the full study at the Statistics Canada Website. The data supports the findings of Canadian neuroscientist Doreen Kimura who has studied sex differences in human brains all her life.
Twitter not a good indicator of scientific impact Posted: December 9, 2013
Trends related to the most-tweeted peer-reviewed scientific papers published between 2010 and 2012, and their social media success, have been identified by Stefanie Haustein at the University of Montreal's School of Library and Information Science. Based on 1.4 million documents from PubMed and Web of Science, it is the largest Twitter study of scholarly articles so far. Consider that a paper about an altered gene during radiation exposure was tweeted 963 times but only received 9 academic citations. "When we look at the most tweeted articles, many have a surprising or humourous character. Articles are often tweeted anecdotally," says her supervisor Vincent Larivière.

Honey bees fight back Posted: 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 homeopathy Posted: August 2, 2012
The new Canadian science advocacy group Bad Science Watch plans to convince Health Canada to de-register homeopathic health products that are offered as unproven replacements for childhood vaccinations.

Expert calls for change in trans fat labelling Posted: September 7, 2011
Not all trans fats are created equal and it's time for nutritional labels to reflect that reality, says Spencer Proctor University of Alberta nutrition expert. About half the people who get heart attacks have normal levels of fat, and some people with higher levels of cholesterol do not get heart attacks. Proctor's research shows that maybe only synthetic trans-fats are bad and naturally occuring ones in cheese and meat are OK.
