When terrified, liberals end up thinking a lot more like  conservatives

by Doug Keene in The Jury Room

It’s a basic tenet of the reptile theory that you want to frighten your jurors to make them vote for your client in deliberation. [The ABA has put out an open-access primer on the reptile theory and you can see that here.] It is also been shown repeatedly that conservatives are more fearful than liberals, […]

A role for dermatologists in diagnosing BHD earlier

by Danielle Stevenson in BHD Research Blog

Birt-Hogg-Dubé (BHD) syndrome was initially described as a heritable dermatological condition based on the presence of multiple fibrofolliculomas, trichodiscomas and acrochordons in a Canadian kindred (Birt et al., 1977). Now it is known that BHD patients can also develop pulmonary cysts, with an associated risk of pneumothorax, and bilateral, multifocal renal tumours. Due to the risk of tumour development it is important that patients are diagnosed early, enabling them to access regular ........ Read more »

How do people with Dark Triad personality traits fare at speed dating?

by BPS Research Digest in BPS Research Digest

People who score highly in the Dark Triad personality traits – narcissism, psychopathy and Machiavellianism – are vain, selfish, callous and manipulative. They're not the kind of people you want to spend much time with. This raises the obvious question – to put it bluntly, why over evolutionary timescales haven't these people died out? One possibility is that their traits actually confer short-term advantages in the mating game. Dark Triad people are obnoxious once you get to know them, su........ Read more »

Mortality and autism: comorbidity counts

by Paul Whiteley in Questioning Answers

I don't enjoy talking about mortality and autism on this blog but once again I'm drawn to discuss this important topic based on some recent findings published by Diana Schendel and colleagues [1]. I say these are important findings on the basis of how researchers took into account the possible role played by psychiatric and neurological comorbidity occurring alongside autism when it comes to the quite alarming mortality statistics.Drawing on the findings reported in their paper and an interview ........

It’s complicated: Benefits and toxicity of anti-prion antibodies in the brain

by Dr. Jekyll in Lunatic Laboratories

Immunotherapy to ameliorate neurodegeneration by targeting brain protein aggregates with antibodies is an area of intense investigation. A new study examines seemingly contradictory earlier results of targeting the prion protein and proposes a cautionary way forward to further test related therapeutic approaches.

A probiotic E. coli from the trenches of World War I

by Rosin Cerate in Rosin Cerate

Escherichia coli is a two-faced little slimeball.As is often the case with bacteria, it comes in many varieties. Some, such as the infamous O157:H7 serotype, can make people very ill. Once inside us (usually via contaminated food or water), they do harmful things like pump out toxins and feast upon the walls of our intestines. We're talking lots of bloody diarrhea.Yet other strains of E. coli have done us a lot of good. For decades now, research laboratories have been using strain K12 and i........ Read more »

Help me, neighbor!

by ragothamanyennamalli in Getting to know Structural Bioinformatics

We all have neighbors who help us in our hour of need. Some go out of the way as well. In enzymes too, it seems, that neighbors play a crucial role. Lafond et al in their recent publication in the Journal of Biological Chemistry report the invovlement of neighboring chains of the same enzyme, lichenase. Apart from the role of stabilizing the quarternary structure (a trimer), they are also invovled in the enzymatic activity.... Read more »

There are at least 216 foreign words for positive emotional states and concepts that we don't have in English

by BPS Research Digest in BPS Research Digest

One criticism levelled at positive psychology is that it takes an overly Western-centric view of the lighter side of human experience. Addressing that problem, Tim Lomas at the University of East London has begun a deep investigation into all the non-English words for positive emotions and concepts that don't have a direct translation in English.Publishing his initial findings in the The Journal of Positive Psychology, Lomas' hope is not only that we might learn more about the positive psyc........

Holding Back: Inhibition

by Joshua Fisher in Text Savvy

I remember years ago being required to write math problems containing unnecessary information so that students would have to choose the information that they needed. But just making kids do something is not the same thing as teaching them something. It is, rather, a total cave to assessment obsession—we just found a way to call assessment "instruction"....

Religion linked to reduced levels of stress hormones in young American Blacks

by Tom Rees in Epiphenom

Compared with Whites, Black Americans have  high levels of an important stress hormone called cortisol circulating in their bloodstream. No-one really knows why this is, but the differences remain even after you take into account social and psychological factors. It seems likely that simply being black exposes you to a cumulative effect of increased lifetime [Read More...]... Read more »

The music of the mind: throwing light on human consciousness

by Dr. Jekyll in Lunatic Laboratories

UNSW Australia scientists have shown that complex human brain activity is governed by the same simple universal rule of nature that can explain other phenomena such as the beautiful sound of a finely crafted violin or the spots on a leopard. The UNSW team has identified a link between the distinctive patterns of brain function that occur at rest and the physical structure of people's brains.
