For 9 years of my life I was a competitive cross country runner. For 9 years of my life I heard the same types of nutritional recommendations: high carbohydrate, low fat, lots of water, eat within 30 minutes of a workout. I know now that total calories seems to matter most (to which increasing dietary fat definitely [...]... Read more »

Xenotropic murine leukemia virus-like virus (XMRV) was discovered in 2006 during a search for viral sequences in prostate cancer tissues. The results of a recent study revealed that the virus is present in 23% of prostate cancers from patients in the US. Understanding the role of XMRV in prostate cancers requires more extensive epidemiological studies, including the examination of tissues from patients in other countries. The prevalence of XMRV in prostate cancers from German subjects has now be........ Read more »

There have been two research studies done, looking at thousand of people to work out how many people with a certain symptom are likely to have cancer.

[W]e have estimated that natural selection drives twice as much change in immune-related proteins as in proteins with no immune function. Interestingly, the rate of adaptation is also more variable among immunity genes than among other genes in the genome, with a small subset of immunity genes evolving under intense natural selection. We suggest that [...]... Read more »

Last year, the psychologists Lawrence Williams and John Bargh gave participants a cup of coffee to hold and showed that the temperature of the coffee affected the way those participants rated a stranger's character. A hot coffee led them to rate him as more good natured and generous, whilst holding an iced coffee had the opposite effect. The finding was touted as an example of embodied cognition - the idea that the way we think about the world is grounded in, and affected by, physical metaphors......... Read more »

GNP is Gross National Product, more or less the sum value of all services and products produced in a year by the inhabitants of a given nation. The value is staggeringly large for the US, somewhere north of $11 trillion. Many wars and worse upheavals have been instigated by politicians - and supported by a populace - in reaction to or anticipation of change of a few percentage points of GNP. All the more reason to dislike forms of society and culture that result in this sort of thing, if you ask........ Read more »

When Jim and Nora were in elementary school, both Greta and I worked challenging jobs, so we did whatever we could to save time. Instead of bringing lunches made by their parents, the kids bought hot meals at school. The school was proud of its cafeteria. Kids had credit accounts, which meant they didn't have to carry lunch money to school (thus making them less of a target for bullies). The children were encouraged to make "healthy choices" instead of just getting a ladleful of mystery meat plo........ Read more »

Cognitive enhancers, also known as nootropics, are a category of drugs with the ability to increase mental performance. Many rave about such “smart drugs” helping them to study, take tests, or increase work performance. Ginkgo biloba, piracetam, and vinpocetine are some popular cognitive enhancers, all with varying mechanisms of action in the human brain. For [...]... Read more »

So yesterday I detailed the results of the Ipsos Reid based milk advertisement that concluded, surprise, that Canadians should be drinking more milk, but buried in the story is the fact that the survey determined that Canadians were not eating enough of any food group according to Canada's Food Guide.Let me repeat that. According to the survey, Canadians don't eat as much food as the Food Guide recommends.But wait, aren't 65% of Canadians overweight? And they're not eating as much as the Food ........ Read more »

Young girls are far more prone than boys to getting stuck in the role of bullying victim. That's according to a new investigation by psychologists who studied hundreds of children at 17 primary schools in Hertfordshire and North London.Dieter Wolke and his colleagues interviewed the children when they were aged between six and nine years and then surveyed them again two or four years later once the children had reached year six. The researchers were interested in the individual and situational f........ Read more »

Many people claim heel spurs to be an abnormal finding. However, research dating from the early 60’s to late 90’s have reported anywhere from 11-16% of the general population to have some type of heel spur. It’s debatable if heel spurs are strongly correlated to older age, gender and osteoarthritis. However, the debate linking heel spurs and pain has progressed to treatment involving shock wave therapy, surgical incision and even radiation therapy The Debate: Traditionally the pathophysiol........
