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

by Paul Whiteley in Questioning Answers

"In this sample of middle-aged adults, drawn from the general population, physical activity was inversely associated with BMI [body mass index] and body fat percentage. For people with the same BMI, those who were more active had a lower body fat percentage."Those were the conclusions made by Kathryn Bradbury and colleagues [1] (open-access) drawing on data derived from "cross-sectional analysis of participants recruited into UK Biobank in 2006–2010." Said results continue a res........ Read more »

Sensory issues in adult ADHD controlling for autistic symptoms...

by Paul Whiteley in Questioning Answers

I was intrigued to read the paper by Bijlenga and colleagues [1] reporting on "the prevalence of sensory hyper- and hyposensitivity among adults with ADHD [attention-deficit hyperactivity disorder], controlling for autistic symptoms."The authors concluded that among their cohort of over 100 adults diagnosed with ADHD, both sensory hyper- and hyposensitivity symptoms as described by response to the Adolescent/Adult Sensory Profile-NL (AASP-NL), were over-represented compared w........

Autistic adults as critical autism experts (with research caveats)

by Paul Whiteley in Questioning Answers

"Findings suggest that autistic adults should be considered autism experts and involved as partners in autism research."That was the conclusion reached in the paper by Kristen Gillespie-Lynch and colleagues [1] (open-access) reporting on the results of an online survey assessing "autism knowledge and stigma among 636 adults with varied relationships to autism, including autistic people and nuclear family members." Among the various groups of people who contributed to the survey, several vie........ Read more »

History of neuroscience: John Hughlings Jackson

by neurosci in Neuroscientifically Challenged















In 1860, when John Hughlings Jackson was just beginning his career as a physician, neurology did not yet exist as a medical specialty. In fact, at that time there had been little attention paid to developing a standard approach to treating patients with neurological disease. Such an approach was one of Jackson's greatest contributions to neuroscience. He advocated for examining each patient individually in an attempt to iden........ Read more »

Parental exposures and risk of offspring autism: some curious details

by Paul Whiteley in Questioning Answers

"Overall, our results were consistent with no positive association between parental asthmagen exposure and ASD [autism spectrum disorder] in the children."So said the findings reported by Alison Singer and colleagues [1] (open-access) continuing a research theme from this group [2] looking at whether "parental workplace exposures to risk factors for asthma (“asthmagens”)" might have relevance to offspring risk for autism.Based on data derived from some of those oh-so-important Scan........

DHM attenuates obesity-induced slow-twitch-fiber decrease via FLCN/FNIP1/AMPK pathway

by Joana Guedes in BHD Research Blog

Obesity is often associated with decreases in the proportion of skeletal muscle slow-twitch fibers and insulin sensitivity. Slow-twitch fibers are rich in mitochondria and utilize fatty acid oxidative phosphorylation for energy production. In their new study, Zhou et al. (2017) explore the role of the FLCN/FNIP1/AMPK signalling pathway in obesity-induced reductions in slow-twitch fibers and insulin sensitivity in skeletal muscle using high-fat-diet-induced (HFD) obese mice, ob/ob mutant mice, an........

Bright highlands in equatorial Venus likely ferro-electric. What's up with the high-latitude highlands?

by Paul Wren in Venus Dispatches

OverviewA lot of papers have been written about the highly reflective highlands (in radar) on Venus, with several different hypotheses (e.g. high porosity, metal frost).  Allan Treiman, Elise Harrington, and Virgil Sharpton look specifically at high-latitude highlands in comparison to highlands in the equatorial regions.  Both areas feature high reflectivity, but the reflectance patterns are distinct, as they describe in Venus' radar-bright highlands: Different signatures and mate........

'Big data' Taiwan is once again the topic of a post on this blog as the results published by Wei-Chen Wang and colleagues [1] (open-access available here) receive an airing, specifically that: "Asthma was associated with increased risk for schizophrenia."There are some common themes attached to these findings. Taiwan is already a research-favourite place on this blog as a result of their use of the National Health Insurance Research Database (NHIRD) for various research purposes. I can't na........

The continuing trials and tribulations of PACE
