If you are couching up blood, then you should make an appointment and mention this to your GP. The chances are it’s not cancer, but you need to [...]... Read more »

On evolution of immunity

by iayork in Mystery Rays from Outer Space


[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 »

A warm room makes people feel socially closer

by Christian Jarrett in BPS Research Digest

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 »

Wars are Fought Over a Few Percentage Points of GNP

by Reason in Fight Aging!

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 »

What does it take to get kids to eat healthy foods?

by Dave Munger in Cognitive Daily

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 »

A mountain lake in Glacier National Park, Montana.

Possible Medical Application of a Smart Drug

by Shaheen Lakhan in Brain Blogger

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 »

Overweight Canadian kids not eating enough according to Canada's Food Guide

by Yoni Freedhoff in Weighty Matters

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 particularly prone to getting stuck in role of bullying victim

by Christian Jarrett in BPS Research Digest

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 »

Heel Spurs? Where do these things come from?

by Sport Injuries and Wellness Ottawa in Sport Injuries and Wellness

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........

Male Chauvinist Chimps or the Meat Market of Public Opinion?

by Eric Michael Johnson in The Primate Diaries

Image: David Bygott / Tree of Life Web Project

Owen Lovejoy's recent paper about Ardipithecus ramidus and human origins (see my detailed critique here) bases its argument on the male provisioning observed in chimpanzees. However, what went unacknowledged in his theory was the inherent gender bias it represented. A perfect example of this was observed in April with the release of the very study on provisioning behavior th........ Read more »

Antiviral and resistance: sialidase inhibitors

From adamantine therapeutics failures, interest in developing new drugs against the flu virus had come up.
