Last Friday I attended the 30th annual 24-hour book sale at the Regent Theatre, Dunedin, held to raise funds to maintain that glorious old place, all red seating with the lolly-decorated proscenium arch and pillars of an older era. Books are donated, collected and sorted by volunteers and “sold” to the punters.
It starts at noon Friday [...]... Read more »

By Hannah Dunbar (Brain Post Note: Hannah Dunbar is a Oral Roberts University undergraduate student who is doing a summer research elective with me. She will be providing some guest posts over the next two months related to her interest in sleep and bipolar disorder.) Bipolar disorder is commonly characterized by sleep fluctations and distrubance of a regular circadian rhythm. It is logical to explore the role of circadian clock genes in bipolar disorder genetic studies. Pediatric bipolar dis........ Read more »

Soffer (2010) thinks that men do 'type 1' health-promoting behaviours (exercise, diet and not snacking) better than women, although he claims that women are better at 'type 2' health-promoting behaviours (not smoking or drinking, sleeping well and eating breakfast) than men.

Standardized tests are supposed to measure innate abilities. The subject of your last conversation, the lead story on the news last night, the pictures on the wall at the test site—this trivia is presumed to have zero impact on your score in geometry or chemistry. Trouble is, it's increasingly clear that this presumption is simply false. Case in point: This study, published in last month's Journal of Social Psychology, which erased the usual gender gap in high-school chemistry ........ Read more »

The perspective that whales, dolphins, and other such marine mammals should be afforded "human rights" has surfaced again.
I thought I'd revisit a post I wrote about this several months ago, from the archives, when this first hit the news after the AAAS conference in San Diego. So here's a modified, updated version of the original post.
The blogosphere is all a-twitter with talk of the recent commentary in Science that dolphins should be considered people. Well, sort of people. Non-human peopl........ Read more »
Do you think you’re good at understanding people by looking them in the eye? This skill is not only important for making money playing poker but for social situations, relationships and everyday professional interactions.Recently, scientific interest in mindreading by looking others in the eye has increased, mainly within the context of ‘theory of mind’ – the general capacity to understand one’s own and other people’s mental states (e.g. emotions, desires, beliefs). A test that is co........ Read more »

Recent studies have shown that, at least in the USA, science and religion don't really mix. Religious people tend to have worse understanding of science, and scientists are, of course, far less religious that the general population (probably because they start out that way, before they ever get to university).
We also know that religious people are much more likely to reject evolution. You think there's a connection here? Well, no doubt. But new research suggests that the connection runs deeper........ Read more »

There are several ways of responding to belief-threatening information. Discounting the ability of science to inform a particular domain of knowledge seems to be one that is used in the light of belief-threatening scientific evidence. Sadly, using the scientific impotence excuse in one domain seems to also increase the likelihood of applying it to science in general...... Read more »

According to biologist Anthony Cashmore’s theory on human behavior, there was no way I wasn’t going to write this blog post. Taking his work to its logical conclusion, it was environmentally and biologically predetermined that I was going to write this sentence and choose these words to do it.

Human beings give their attention readily to people who already have it. It doesn't matter if a guy won fame for his action movies, people will listen to his advice on carbon sequestration, and go out an buy his brand of shoe. That's not logical, but it does follow a predictable rule, which is that being famous, "cool" and/or prestigious gives you ready access to the minds of others. That bias may have evolved a very long time ago, according to this paper in the journal PLoS One last w........ Read more »

Cooperation is seen not only in humans, but in societies formed by organisms from ants to baboons. But in many cases, it’s difficult to figure out why any individual would want to cooperate.

A focus group study of parents' attitudes towards interventions promoting uptake of the MMR vaccine suggests it is better for health advice to be seen as independent from government.

Another look at MDMA and serotonin.
A study by Canada’s Centre for Addiction and Mental Health (CAMH) has confirmed earlier findings that chronic users of ecstasy (MDMA) have abnormally low levels of serotonin transporter molecules in the cerebral cortex.
While a decade of research on the effects of ecstasy on brain serotonin has been controversial and largely inconclusive, the latest study used drug hair analysis to confirm levels of MDMA in 49 users and 50 controls. An additional division ........ Read more »
