Planned Parenthood is disgusting? What does that even mean?

by Tom Rees in Epiphenom

Whatever the ins and outs behind the tragic shootings at Planned Parenthood clinic in Colorado, it seems safe to assume that the heated and inflammatory rhetoric that has characterised the debate around abortion in the USA has played a major role. A couple of weeks ago, Planned Parenthood innocently asked Twitter users for one word [Read More...]... Read more »

Mitochondrial response to BCKDK-deficiency and 'some' autism

by Paul Whiteley in Questioning Answers

I'll admit to being pretty fascinated by the Branched Chain α-Keto acid Dehydrogenase Kinase (BCKDK) gene. As per previous blog entries about this gene (see here and see here) and the important biological step it plays in the metabolism of the branched-chain amino acids (BCAAs), at least one 'form' of autism might be particularly sensitive to issues with it [1]. I take it you've heard of the idea that the autisms (plural) might be a better description of autism? If you haven't, here is a p........ Read more »

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 »

2% of UK 16-year olds with chronic fatigue [syndrome]?

by Paul Whiteley in Questioning Answers

"CFS [chronic fatigue syndrome] affected 1.9% of 16-year-olds in a UK birth cohort and was positively associated with higher family adversity. Gender was a risk factor at age 16 years but not at age 13 years or in 16-year-olds without high levels of depressive symptoms."So said the findings reported by Simon Collin and colleagues [1] which also gained some media interest as per an entry on the BBC news website for example (see here). Based on data generated by the Children of the ........ Read more »

Starting age of marijuana use may have long-term effects on brain development

by Dr. Jekyll in Lunatic Laboratories

The age at which an adolescent begins using marijuana may affect typical brain development, according to researchers at the Center for BrainHealth at The University of Texas at Dallas. In a paper recently published, scientists describe how marijuana use, and the age at which use is initiated, may adversely alter brain structures that underlie higher order thinking.

Does 3D Make You Queasy? You Might Have Superior Vision

by Elizabeth Preston in Inkfish



Between the rise of 3D movies and virtual reality, more and more people are getting a chance to don goofy glasses or headsets and experience media in three dimensions. And many of those people are discovering something about themselves: 3D makes them ill. Sitting in the theater or on their own couch, they get a sensation like motion sickness. They might feel nausea, dizziness, or disorientation.

A new study suggests that these symptoms aren't weakness on the part of the viewer. People who... Read more »

Researchers have analysed the somniloquies of the world's most prolific sleep talker

by BPS Research Digest in BPS Research Digest

Album artwork for Dion McGregor Dreams AgainThe "most extensive sleep talker ever recorded", according to a new article in Imagination, Cognition and Personality, is the late American songwriter Dion McGregor. McGregor's unusual sleeping behaviour – one commentator said he "sounds as if he were channeling Truman Capote on acid: flirtatious, slushy, disconnected from reality ..." – first became public in the 1960s when McGregor shared a New York apartment with a posse of o........

Autism and the 'female camouflage effect'

by Paul Whiteley in Questioning Answers

Two papers provide some blogging fodder today. The first is from Agnieszka Rynkiewicz and colleagues [1] (open-access available here) who introduces a concept that many people with an interest in autism might have considered: a 'female camouflage effect' in autism. The second paper is by C Ellie Wilson and colleagues [2] and continues the idea that sex/gender differences present in autism might have some important implications for diagnostic evaluation.Both these papers entertain ........

Brain power: Wirelessly supplying power to the brain

by Dr. Jekyll in Lunatic Laboratories

Human and animal movements generate slight neural signals from their brain cells. These signals obtained using a neural interface are essential for realizing brain-machine interfaces (BMI). Such neural recording systems using wires to connect the implanted device to an external device can cause infections through the opening in the skull. One method of solving this issue is to develop a wireless neural interface that is fully implantable on the brain.

New research challenges the idea that women have more elaborate autobiographical memories than men 

by BPS Research Digest in BPS Research Digest

The longest autobiographical narratives were produced by men talking to women Prior research has found that women elaborate more than men when talking about their autobiographical memories, going into more detail, mentioning more emotions and providing more interpretation. One problem with this research, though, is that it hasn't paid much attention to who is listening or whether the memories are spoken or written.This is unfortunate because findings like these can fuel overly sim........

Baby can see, what an adult can’t

by Usman Paracha in SayPeople

Main Point:

Babies have an unusual ability to see those things and differences in pictures that are not visible to adults.

Published in:

Current Biology

Study Further:

In a study conducted by researchers from Japan, it has been reported that infants under 5 months of age have an ability to detect changes in pictures or images that are not visible to adults. However, this ability disappears rapidly, and infants in the age range of 5 months to 6 months are unable to detect image dif........ Read more »

Decreased brain levels of vitamin B12 in autism

by Paul Whiteley in Questioning Answers

I have to thank Dr Malav Trivedi for bringing my attention to some recent findings reported by Yiting Zhang and colleagues (including Malav) [1] (open-access) suggesting that: "levels of vitamin B12, especially its MeCbl [methylcobalamin] form, decrease with age in frontal cortex of control human subjects."Further, researchers reported: "abnormally lower total Cbl [cobalamin] and MeCbl levels in subjects with autism and schizophrenia, as compared to age-matched cont........

How the home crowd affects football referees' decisions

by BPS Research Digest in BPS Research Digest

One of the most thorough investigations into referee bias has found that they tend to award harsher foul punishments to the away team. The new results, published in the International Journal of Sport and Exercise Psychology, suggest that experienced referees are just as prone to this bias as their less experienced colleagues.Andrés Picazo-Tadeo and his team analysed data from 2,651 matches played in the First Division of La Liga, the Spanish Football League between the 2002/3 and 2009/10 season........

"People with ASD had lower odds of employment in the community"

by Paul Whiteley in Questioning Answers

The title of this quite brief post refers to an important finding detailed by Derek Nord and colleagues [1] who, when analysing data from the "2008–09 National Core Indicators Adult Consumer Survey", concluded that there were some important inequalities when it came to employment rates for those diagnosed on the autism spectrum.Employment rates and work opportunities for people diagnosed with an autism spectrum disorder (ASD) is a hot topic at the moment.

The molecular link between psychiatric disorders and type 2 diabetes

by Dr. Jekyll in Lunatic Laboratories

There may be a genetic connection between some mental health disorders and type 2 diabetes. In a new report, scientists show that a gene called “DISC1,” which is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder and some forms of depression, influences the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels.

Brain plasticity assorted into functional networks

by Dr. Jekyll in Lunatic Laboratories

Plasticity of the brain, what does that even mean? Well the good news is that it isn’t just a marketing ploy, the brain needs to be “plastic” because we need to be able to adapt. Frankly speaking, the brain still has a lot to learn about itself. Scientists at the Virginia Tech Carilion Research Institute have made a key finding of the striking differences in how the brain’s cells can change through experience.

"Troubling Oddities" In A Social Psychology Data Set

by Neuroskeptic in Neuroskeptic_Discover

A potential case of data manipulation has been uncovered in a psychology paper. The suspect article, Why money meanings matter in decisions to donate time and money, came out in 2012 from University of Arizona psychologists Promothesh Chatterjee, Randall L. Rose, and Jayati Sinha.

This study fell into the genre of 'social priming', specifically 'money priming'. The authors reported that making people think about cash reduces their willingness to help others, while thinking of credit cards has... Read more »

Sleep as a target of antibiotic use in chronic fatigue syndrome?

by Paul Whiteley in Questioning Answers

"The primary finding from the study was evidence of an improvement in several objective sleep parameters in participants in whom the increased colonization of lactic acid producing organisms was resolved after antibiotic treatment."Those were the words written by Melinda Jackson and colleagues [1] (open-access) who, during an open-label trial, looked at whether administration of an antibiotic (erythromycin 400 mg) over the course of 6 days might have some important effects on elements of sleep i........
