A poo transplant for [some] autism?

by Paul Whiteley in Questioning Answers

I've talked about 'fecal microbial transplants' a.k.a the poo(p) transplant before on this blog (see here). That previous entry was about the more typical (and potentially life-saving) use of a poo transplant - where stool from one person is extracted, 'repackaged' and transferred to another person - albeit with caveats in terms of possible long-term side-effects. Now it appears that poo transplants are being investigated with something rather more central to the typical cont........

Generational labels, researching emojis, and two persuasion  landmines

by Rita Handrich in The Jury Room

We read so much for this blog (and just out of general curiosity) that we often find these small bits of information which don’t justify an entire blog post but that we want to share with you because they are just too good to ignore. Here’s another one of those combination posts that you simply […]... Read more »

Autism and visual impairment reviewed

by Paul Whiteley in Questioning Answers

Of the various autism science journals out there in peer-reviewed (La-La!) land, one journal in particular is really starting to grow on me: [The] Review Journal of Autism and Developmental Disorders.I like this journal because it is basically systematic review and meta-analysis heaven when it comes to the quite voluminous autism research literature and seems to publish some real gems (see here for example).Another paper from this journal caught my eye recently by Maggie Butchart and colleagues ........

Crowdfunding and Tribefunding in Science

by Jalees Rehman in The Next Regeneration

Competition for government research grants to fund scientific research remains fierce in the United States. The budget of the National Institutes of Health (NIH), which constitute the major source of funding for US biological and medical research, has been increased only modestly during the past decade but it is not even keeping up with inflation. This problem is compounded by the fact that more scientists are applying for grants now than one or two decades ago, forcing the NIH to enforce strict........ Read more »

Whip Spiders Use Their Feet to Smell Their Way Home

by Elizabeth Preston in Inkfish



After a late dinner, a jungle-dwelling whip spider can't rely on an Uber driver to get her home. She has to find the way herself, in the pitch-black, picking her way over thick undergrowth to reach the tree she lives on. It's a trick she can even manage when plucked from her home tree and tossed into the forest at random, up to 10 meters away. Now scientists think whip spiders don't use her eyes for this homing feat—they use their feet.

Whip spiders hunt by night and hunker down at dawn ........ Read more »

Fatty acids 'for autism'? Meta-analysis says probably not but...

by Paul Whiteley in Questioning Answers

"Because of the limited number of included studies and small sample sizes, no firm conclusions can be drawn. However, the limited data currently available suggest that ω-3 FA [fatty acid] supplementation does not enhance the performance of children with ASD [autism spectrum disorder]."Those were the conclusions reached in the systematic review and meta-analysis paper published by Andrea Horvath and colleagues [1] looking at the collected peer-reviewed literature on the topic up t........

Forensic Science Testimony: What most  influences jurors? 

by Doug Keene in The Jury Room

We all want our expert witnesses to be influential with jurors. But when you have an expert testifying about forensic science (like fingerprint or DNA identification) what part of the testimony is going to influence jurors the most? Will it be the science? The technology used by the witness to interpret and understand the data? […]... Read more »

Autism diagnoses (and diagnostic stability) in Germany

by Paul Whiteley in Questioning Answers

"From 2006 to 2012, the prevalence of autism spectrum disorder diagnoses in 0- to 24-year-olds increased from 0.22% to 0.38%."That was one of the details included in the rather interesting paper by Christian Bachmann and colleagues [1] who provided some introductory information on the the trends in autism diagnoses in Germany. I say 'introductory information' because it appears that autism or autism spectrum disorder (ASD) has not exactly received the research attention in Germany that it p........ Read more »

Nature Shapes Faithful and Unfaithful Brains

by Miss Behavior in The Scorpion and the Frog

Among monogamous animals, some individuals are more faithful than others. Could these differences in fidelity be, in part, because of differences in our brains? And if so, why does this diversity in brain and behavior exist?A snuggly prairie vole family. Photo from theNerdPatrol at Wikimedia Commons.Prairie voles are small North American rodents that form monogamous pair bonds, share parental duties, and defend their homes. Although prairie voles form monogamous pairs, that does not mean they ar........ Read more »

"no evidence that the probiotic formulation is effective in treating low mood"

by Paul Whiteley in Questioning Answers

I'm a great believer in balance when it comes to this blog and its content. As enthusiastic as I might be about a particular topic or topics, I don't want to lose sight of the fact that peer-reviewed science is a messy business and often filled with contrary findings.With 'contrary' in mind, I want to talk today about a paper by Amy Romijn and colleagues [1] detailing the results of a double-blind, randomised, placebo-controlled trial of a probiotic mix which contained "freeze-dried L. helv........

Diagnosing ME/CFS the machine learning way?

by Paul Whiteley in Questioning Answers

In today's post I want to draw your attention to the findings reported by Diana Ohanian and colleagues [1] (open-access available here) talking about "the use of machine learning to further explore the unique nature"of various conditions/labels including those typically headed under the label of chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME).Including one 'Jason LA' on the authorship list, researchers set about looking at "what key symptoms differentiate Myalgic Encephalomyelitis ........

The correlates of regressive autism

by Paul Whiteley in Questioning Answers

"A more homogeneous subgroup with regression between 18 and 36 months (n = 48) had higher rates of intellectual disability, epilepsy, and special education, more socially restrictive educational settings, and more severe ASD [autism spectrum disorder] communication deficits and schizophrenia spectrum symptoms than non-regressed youth (n = 136)."So said the findings reported by Kenneth Gadow and colleagues [1] taking on one of the more important issues in relation to autism: dev........

Finding Out if Dogs Like Cats - Or Not

by CAPB in Companion Animal Psychology Blog

A new study investigates the best way to find out if a dog will get on with cats.When dogs are waiting for adoption at a shelter, a common question is “what is the dog like with cats?” But at the moment there’s no validated way to test dogs to see if they will be friendly to cats.Some dogs become good friends with cats, but other dogs want to chase and kill them, so it would really help if shelters knew if a dog is cat-friendly.Sometimes the person who surrenders a dog will provide informa........

Nasty women earn more money (but it isn’t all roses) 

by Doug Keene in The Jury Room

We have written a lot about how women are treated unequally (which can, sometimes, make it hard to be a woman). Initially, we illustrated these posts with various photos of Tammy Wynette but we decided to stop picking on her for one song (“Stand By Your Man”). So this post illustrates a rough truth (that […]... Read more »

Physical activity levels and autism (again)

by Paul Whiteley in Questioning Answers

"Adolescents with ASD [autism spectrum disorder] spent less time in MVPA [moderate and vigorous physical activity] compared to TD [typically developing] adolescents (29 min/day vs. 50 min/day, p < 0.001) and fewer met the Physical Activity Guidelines for Americans (14 vs. 29%, p > 0.05)."So said the study results published by Heidi Stanish and colleagues [1] adding yet more to another growth autism research area - physical activity and exercise - ........

Vitamin D supplementation and self-perceived fatigue

by Paul Whiteley in Questioning Answers

"Vitamin D treatment significantly improved fatigue in otherwise healthy persons with vitamin D deficiency."Supplementation details, described in the paper by Albina Nowak and colleagues [1] (open-access available here), were a single dose of 100,000 IU [international units] of vitamin D or a placebo (mannitol) administered to 120 adult participants who presented with "fatigue and vitamin D deficiency (serum 25(OH)D < 20 μg/L)." This was a double-blind trial and self-perceived fatigue ........ Read more »

Simple Jury Persuasion: Using your expert  witnesses’ hands help persuade jurors

Autism-like traits and/or autism elevated in psychosis

by Paul Whiteley in Questioning Answers

"Rates of ASD [autism spectrum disorder] and ASD traits are elevated in a psychosis population."The paper by Debbie Kincaid and colleagues [1] provides yet more [short] blogging material pertinent to the increasing interest in how psychosis may be yet another comorbidity over-represented when it comes to autism (see here) and vice-versa. I know this is another topic that has to be treated with some caution in terms of concepts like stigma but more discussions - science discussions........ Read more »
