ADHD and suicide
by Paul Whiteley in Questioning Answers
"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)

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.

On abuse exposure and mate selection

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........

Autism, pregnancy maternal immune activation and vitamin D?

The findings reported by Vivien Suchert and colleagues [1] observing that "screen time, but not other non-screen-based sedentary activities should be considered as being a risk factor for ADHD [attention-deficit hyperactivity disorder]" taps into long-running debates on whether our societal obsession with watching, clicking and swiping might not be 'a totally positive thing' when it comes to psychological development, health and wellbeing.Yes, I know this is a complicated area ful........

The Brightness Temperature of the Quiet Solar Chromosphere at 2.6 mm by Kazumasa Iwai et al
by CESRA in Solar Radio Science
The brightness temperature of the Sun constitutes a basic property of the solar atmosphere. The main emission mechanism of the Sun at millimeter and submillimeter wavelengths is thermal free–free emission from the chromosphere, which is an atmospheric layer with a temperature ranging between 6000 to 20,000 K. The opacity of thermal free–free emission depends on the temperature and density in the emission region. In addition, the Rayleigh– Jeans law is applicable [...]... Read more »

Who'd have thunk it: physical activity inversely associated with BMI and body fat percentage
