"Dietary fiber deprivation, together with a fiber-deprived, mucus-eroding microbiota, promotes greater epithelial access and lethal colitis by the mucosal pathogen, Citrobacter rodentium."So said the findings reported by Mahesh Desai and colleagues  meriting an editorial in the publishing journal  as the sentiments of 'eating your greens' applies to some rather interesting [mouse] findings.Fibre (UK spelling) comes in various different forms typically categorised as soluble and insoluble d........

Making time for play immediately after a dog training session improves the dog’s memory.New research by Nadja Affenzeller (University of Lincoln) et al investigates whether play following learning leads to better performance the next day. The scientists wanted to know whether this effect, previously found in humans, would also apply to dogs.In people, it is thought that the hormonal response during positive arousal acts on parts of the brain called the hippocampus and amygdala and leads to........

The findings reported by Maureen Russell and colleagues  provide some blogging fodder today and the observation that: "Biological caregivers of children with ASD [autism spectrum disorder] demonstrated a high prevalence of RLS [Restless Legs Syndrome] symptoms and poorer mental health."OK, I know some people might be asking 'just what is Restless Legs Syndrome'? It is a recognised condition complete with 'disease' title (Willis-Ekbom disease). Symptoms, as the name suggests, centre ........ Read more »

The title of the paper by Konstantin Mechler and colleagues - "Defining the hidden evidence in autism research. Forty per cent of rigorously designed clinical trials remain unpublished - a cross-sectional analysis"  - provides some discussion today. Drawing on the ideas that publication bias and/or the so-called 'file-drawer problem' - terms that refer to the non-publication of study results potentially skewing the collected scientific opinion in a particular area - might also exten........

We’ve written about atheists here (and how unpopular they are in North America) a number of times. The first time was in 2010 when we wrote an article in The Jury Expert because we were so taken aback by the level of vitriol we’d seen in a blog post describing a new research article on […]

The paper by Nahit Motavalli Mukaddes and colleagues  provides some important, if small-scale, information when it comes to that still controversial term - optimal outcome - with the diagnosis of autism in mind. Optimal outcome basically refers to a particular 'type' of autism whereby following a definite diagnosis of autism or autism spectrum disorder (ASD), a later re-evaluation of signs and symptoms reveals that diagnostic thresholds are subsequently not reached and/or exceeded a........

The paper by Wenjie Sun and colleagues  (open-access) provides the blogging fodder for today's post and although based on the science of epigenetics, the usual suspect - DNA methylation - gives way to another concept: histone acetylation with autism in mind. Before heading into the paper myself, I'll draw your attention to some other write-ups of the study including a hat-tip to Jeff Craig and his piece on the topic (see here).So histone acetylation...

Children’s beliefs about animal welfare and sentience are linked to their own experiences with animals.Surprisingly little is known about children’s beliefs and knowledge about animals. Yet this information could help to improve humane education programs for children. Two recent studies begin to fill this gap, with recommendations for how humane education is taught.We know from previous research that even very young children like animals, and that children with pets are more likely to attrib........

"This study does not support the hypothesis that MPH [methylphenidate] increases risk of incident psychotic events. It does indicate an increased risk of psychotic events before the first prescription of MPH, which may be because of an association between psychotic events and the behavioural and attentional symptoms that led to psychiatric assessment and initiation of MPH treatment."The results published by Man and colleagues  (open-access) sit right with me. I say that on the basis........ Read more »

I'm gonna be fairly brief today and draw your attention to yet another systematic review and meta-analysis this time looking at how "probiotic supplementation can have a positive effect on mood and psychological symptoms such as depression and anxiety."

Franz Joseph Gall (1758-1828), a founding father of phrenology
Phrenology was the pseudoscience of identifying a person's character and mental abilities on the basis of skull morphology (“bumps on the head”). The enterprise was based on four assumptions (Gross, 2009):
intellectual abilities and personality traits are differentially developed in each individual

Are the eyes the windows to intelligence? In an interesting paper, Georgia psychologists Jason S. Tsukahara and colleagues report that there's a positive correlation between pupil size and cognitive ability.
It's well known that our pupil size varies over time due to changes in both emotional state and cognitive 'effort'. As Tsukahara et al. put it
Starting in the 1960s it became apparent to psychologists that the size of the pupil is related to more than just the amount of light enterin... Read more »

The results published by Robert Joseph and colleagues  provide some blogging fodder today, observing that as part of the ELGAN (Extremely Low Gestational Age Newborns) Research Study, gestational age might matter when it comes to offspring risk of autism spectrum disorder (ASD).Gestational age is a measure of how far along a pregnancy is but in the context of the Joseph study refers to premature birth or those "born at least 3 months early." Researchers included data for nearly 1000........ Read more »

It does not come as a surprise that background music in a café helps create the ambience and affects how much customers enjoy sipping their cappuccinos. But recent research suggests that the choice of lyrics can even impact the social behavior of customers.

Consider this short blog post an extension of some previous discussions (see here and see here) on a rather peculiar 'association' between urinary tract infections (UTIs) and psychosis. UTIs basically refer to an infection in any part of the urinary system (kidneys, bladder, etc) typically treated with antibiotics. Psychosis is a state that causes a person to perceive or interpret things around them in an atypical way, usually accompanied by delusions or hallucinations. For a while now........ Read more »

Papers such as the one published by Nikko Da Paz & Jan Wallander  I think represent one of the most important areas of autism research and practice when it comes to the practical translation of science to real-life. Tackling a very important topic - caring for the carers - the authors provide a "narrative review" of the peer-reviewed science literature looking at how "treatments that directly target parents' psychological well-being" in the context of autism are doing so far.Personally, I........

A remarkable paper claims that staying off Facebook for a week could make you happier: The Facebook Experiment, by Morten Tromholt of Denmark.
What makes this study so interesting is that it was a randomized controlled trial (RCT) and so was able, at least in theory, to determine whether quitting Facebook actually causes changes in well-being. Previously, there has been lots of research reporting correlations between social network use and happiness, but correlation isn't causation.
