A couple of months ago I pointed out that a Letter published in the American Journal of Psychiatry, critiquing a certain paper about antidepressants, made very similar points to the ones that I did in my blog post about the paper. The biggest difference was that my post came out 9 months sooner.Well, it's happened again. Except I was only 3 months ahead this time. Remember my post Clever New Scheme, criticizing a study which claimed to have found a brilliant way of deciding which antidepressan........ Read more »

Attitudes and beliefs of trainee probation officers: A ‘new breed’? From Probation Journal In recent years the UK Government has been placing less emphasis on the idea of probation as a form of rehabilitation, instead re-framing it as ‘punishment in the community,’ with a focus on protecting the public. It has promoted the idea that [...]... Read more »

Speakers with a foreign accent are perceived as less believable than native speakers. A new study shows this isn't just because of prejudice towards 'outsiders'. It also has to do with the fluency effect, one manifestation of which is our tendency to assume that how easily a message is processed is a mark of its truthfulness. The effort required to understand an accented utterance means that the same fact is judged as less credible when uttered by an accented speaker, compared with a native spea........ Read more »

From the outset of this post, it must be noted by The Editor, that this blog wholly acknowledges and supports Darwin's Theory of Evolution. Furthermore, this article is not intended to question Darwin's work or theory, or the masses of fossil evidence, and DNA evidence that further supports his theory. Ergo, any comments of an aggressive or distasteful nature shall be removed, especially if contributors attempt to bring the debate of religion vs science into this domain.This article shall e........

In research and development, it’s often taken for granted that teams require a certain critical mass to be successful. Indeed, in a recent paper  two European researchers claim to have seen the effects of critical mass in the UK Research Assessment Exercise (RAE) and its French equivalent (HT: Mark Wilson). However, I think that [...]... Read more »

The tightly regulated balance between secretion and removal of neurotransmitters is not functioning properly in certain mental conditions like bipolar disorder, obsessive-compulsive disorder, anxiety, and depression. Neurotransmitters are signaling molecules used to transmit messages between neurons (nerve cells) in the brain. Serotonin is one of the neurotransmitters affected in depression and similar disorders. The most common class of [...]... Read more »

I'm going to be coming out with a new post in my Evolution series later this week, but in the meantime, for those of you haven't seen them, I'm reposting my first two Evolution posts, beginning with the one that started the series: The Curious Case of Dogs.

For a leaf-cutter ant, the answer to that question is not so much “silver bells and cockle-shells” as it is “one nutritious fungus and a variety of beneficial bacteria.” It may not exactly be the stuff of nursery rhymes, but it’s certainly a fascinating three-way mutualism that makes for a great lesson in microbial ecology, [...]...

What is the relationship between national identity and politicization? In an era of widespread concerns over terrorism and the integration of minorities in Western societies, this is a relevant question. If one's identification with the new home country increases, what is the consequence for levels and types of political activity?

3D Model of Chemical Structure for BupropionBupropion is a drug approved in the United States for the treatment of depression (Wellbutrin) and for smoking cessation (Zyban). In contrast to the selective serotonin reuptake inhibitor (SSRI) class of drugs, i.e. Prozac, bupropion appears to have a predominant effect on blocking the reuptake of dopamine. It appears to also be a nicotinic acetylcholine receptor antagonist possibly contributing to it’s effect on nicotine withdrawal sympt........ Read more »
