You Read It Here First...Again

by Neuroskeptic in Neuroskeptic

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 »

by SAGE Insight in SAGE Insight

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 »

Genetic watersheds on the Great Himalayas

by Razib Khan in Gene Expression

One of the great geological landmarks on earth are the Himalayas. Not only are the Himalayas of importance in the domain of physical geography, but they are important in human geography as well. Just as South Asians and non-South Asians agree that the valley of the Indus and its tributaries bound the west of the [...]... Read more »

Speakers with a foreign accent are perceived as less credible - and not just because of prejudice

by BPS Research Digest in BPS Research Digest

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 »

Jean Baptiste Lamarck: Founder of Lamarckian Evolution

by John Wayland in The Darwin Tribune

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........

Critical mass or is mass critical?

by Shaun Hendy in A Measure of Science

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 [1] 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 [...]...

How Prozac works

by Shaheen Lakhan in Brain Blogger

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 »

Evolution: The Curious Case of Dogs [Observations of a Nerd]

by Christie Wilcox in Food Matters

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.

Man's best friend is much more than a household companion - for centuries, artificial selection in dogs has made them prime examples of the possibilities of evolution. A century and a half ago, Charles Darwin recognized how the incredibly di........ Read more »

The pandemic Influenza keeps reassorting

by Atila Iamarino in Influenza A (H1N1) Blog – English

After more than a year of the Influenza A H1N1 episode, the virus is still being monitored all over the world, both the flu cases and genetics diversity of the virus. Following up the genetic diversity helps to understand if the vaccine is still efficient and helps identifying the possible appearance of new strains.
In Hong [...]... Read more »

Referential labelling in Diana Monkeys

by Hannah Little in A Replicated Typo 2.0

Ok, so I was going to write an essay for my Origins of Language module on this but then got distracted by syntax (again) so I thought I’d put my thoughts in a blog post just so they don’t go to waste.

Diana monkeys, like vervet monkeys, use alarm calls to communicate the presence of a predator . . . → Read More: Referential labelling in Diana Monkeys... Read more »

The Illusion of the Curveball

by Brian Mossop in The Decision Tree

My latest post is up at Wired Playbook, describing the optical illusion we commonly refer to as the curveball: The average curveball hurls toward a batter at around 75 mph, accentuated by a 1500 rpm spin. From the moment the ball leaves the pitcher’s hand, it travels a smooth, consistent, parabolic arc. There’s no disjointed [...]... Read more »

How does your garden grow?

by microbialmodus in Microbial Modus

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, [...]...

Migrant identity and politicization

by Kris-Stella in Coffee Shop Philosophy

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? Bernd Simon and Olga Grabow have published some interesting new research on the topic. Looking at Russian migrants in Germany (replicating a design that has previously........ Read more »

Bupropion for the Treatment of Sexual Dysfunction

by William Yates, M.D. in Brain Posts

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........
