Vitamin D genes and autism

by Paul Whiteley in Questioning Answers

"Vitamin D deficiency is a putative environmental risk factor for autism spectrum disorder (ASD)."And..."We provide straightforward genetic evidences for the first time that VDRGs [vitamin D-related genes] with a strong degree of DNM [de novo mutations] burden in ASD and DNMs of VDRGs could be involved in the mechanism underlying in ASD pathogenesis."That was the research bottom line reported on by Jinchen Li and colleagues [1] examining an important part of the whole 'vitami........

Is "Allostasis" The Brain's Essential Function?

by Neuroskeptic in Neuroskeptic_Discover

A paper just published in Nature Human Behaviour makes some big claims about the brain. It's called Evidence for a large-scale brain system supporting allostasis and interoception in humans, but how much is evidence and how much is speculation?



The authors, Ian R. Kleckner and colleagues of Northeastern University, argue that a core function of the brain is allostasis, which they define as the process by which the brain "efficiently maintains energy regulation in the body". Allostasis ent... Read more »

Lies, lies and more lies: An update on deception research 

by Doug Keene in The Jury Room

All this week, we have focused on research about lying but there are multiple other articles we want to share with you that will not require a full post. Think of this post as an update on deception that will aid you in preparation for court (and life in general). Small, self-serving lies change our […]... Read more »

Trends in ADHD medication use in the US and Europe: is this a bad thing?

by Paul Whiteley in Questioning Answers

I don't want to dwell too much on the findings reported by Christian Bachmann and colleagues [1] observing that in five Western countries - Denmark, Germany, the Netherlands, the United Kingdom (UK) and the United States (US) - ADHD (attention-deficit hyperactivity disorder) medication use between 2005/2006-2012 was on the increase. But I do think it is important to mention some of the implications from such figures and some of the positives and negatives associated with such generated........ Read more »

The findings reported by Tamara May and colleagues [1] are discussed today, looking at self-reported sexual attraction and past sexual relationships among adolescents diagnosed with an autism spectrum disorder (ASD) compared with not-autism controls.Asking 14-15 year olds who took part in The Longitudinal Study of Australian Children (94 diagnosed with autism and some 3400 controls) some rather personal questions, researchers reported that: "ASD males reported fewer prior boyfriends/gi........

Gimme Your Lunch Money!: Feeding Behaviors in Hummingbirds

by Melissa Chernick in Science Storiented

Ubatuba, São Paulo, Brazil; 9 October 2014 © Almir Cândido de AlmeidaI just put out my hummingbird feeder this season. It didn’t take those little guys long to find it either. Now I’ve got their cute little bodies whizzing about all over the place. They need Yackety Sax to play as their soundtrack. But it got me to thinking about hummingbirds and to looking through recent papers for a good study. I came across one in Zoologia about the feeding behavior of hummingbirds in artificial f........

How Can We Measure Human Oxytocin Levels?

by Neuroskeptic in Neuroskeptic_Discover

Is oxytocin really the love and trust chemical? Or is it just the hype hormone? A new paper suggests that many studies of the relationship between oxytocin and behaviors such as trust have been flawed.





The paper is a meta-analysis just published by Norwegian researchers Mathias Valstad and colleagues. Valstad et al. found that the level of oxytocin in human blood, often used as a proxy measure of brain oxytocin, has no relation to central nervous system oxytocin levels under normal co...

Artful Paltering: One more way people lie (especially in  negotiations!)

by Rita Handrich in The Jury Room

Back in 2010, we posted on an article called Artful Dodging that talked about how politicians in particular, answer the question they prefer to answer rather than the question you asked. We talked about responding to that strategy in voir dire. Now, we have another article from the same group of researchers and this one […]... Read more »

ADHD and suicide

"There is a positive association between ADHD [attention-deficit hyperactivity disorder] and suicidality in both sexes and in all age groups."So said the results of the systematic review published by Balazs & Kereszteny [1] (open-access available here) who surveyed the recent peer-reviewed literature on the topic between 2011 and 2015. Reporting results based on findings included in 26 papers, authors concluded that suicidality - ideation, behavior, attempts, and suicide ........ Read more »

Openness is the only quality of an academic article that can be objectively measured

by SciELO in SciELO in Perspective

Quality of scientific research articles is a widespread preoccupation in academic circles. The most used proxy is based on citation counts, not of the article itself, but of the averages of articles appearing in the same journal during a given time window. This is known as the Journal Impact Factor, which may be objective within its own definition, but utterly lacks objectivity with regard to scientific quality of individual articles. Only some technical qualities of articles can be assessed at ........ Read more »

Sharing the Future with Artificial Intelligence

by Aurametrix team in Aurametrix Blog

Artificial intelligence has reached a buzzword utopia as it seems everyone is talking about self-driving cars, delivery drones and virtual assistants with human-like "intelligence." Some believe this new era of AI will make the American Dream universally accessible, enabling early retirement in bucolic settings. Others are concerned about a greater inequality created by a jobless future.... Read more »

The illusion of truth (which is why you should never  repeat fake news)

by Rita Handrich in The Jury Room

It’s been all about “fake news” for a while now and here’s a study telling us to just stop talking about it. Well, sort of. What it actually says is even when we have knowledge to the contrary, if we hear something repeated enough—we come to believe it. Hence, our recommendation that we need to […]... Read more »

On abuse exposure and mate selection

by Paul Whiteley in Questioning Answers

The paper by Andrea Roberts and colleagues [1] is offered up for brief discussion today, and a slightly uncomfortable but nonetheless potentially important set of results that "provide evidence that childhood abuse affects mate selection, with implications for offspring health."I tread very carefully with this topic but was intrigued by the findings looking at whether 'offspring health' in the context of the presence of autism or autism spectrum disorder (ASD) might be at least sometimes mediate........

New Human Rights for the Age of Neuroscience?

by Neuroskeptic in Neuroskeptic_Discover

Do we have a human right to the privacy of our brain activity? Is "cognitive liberty" the foundation of all freedom?



An interesting new paper by Swiss researchers Marcello Ienca and Roberto Andorno explores such questions: Towards new human rights in the age of neuroscience and neurotechnology

Ienca and Andorno begin by noting that it has long been held that the mind is "a kind of last refuge of personal freedom and self-determination". In other words, no matter what restrictions might... Read more »
