More than Meets the Eye

by Aurametrix team in Aurametrix Blog

Eyeglasses are almost as old as the civilization itself. They have not changed much since Benjamin Franklin's bifocals in the 18th century. Nor were they made obsolete by laser surgery and contacts. Still, eyeglass technology leaves much to be desired. But new technologies are unfolding before our eyes. ... Read more »

Pregnancy exposure to SSRIs and offspring autism risk: debate continues

by Paul Whiteley in Questioning Answers

"It remains unclear whether the association between first trimester SSRI [selective serotonin reuptake inhibitor] exposure and child autism that was present in the case-control studies even after adjustment for MMI [maternal mental illness] is a true association or a product of residual confounding."So said the results of the systematic review and meta-analysis undertaken by Hilary Brown and colleagues [1] looking at a potentially important association between pregnancy use of a class ........

Scientific reliability and the role of theory

by Multiple Authors in EPPI-Centre blog

The replication crisis, publication bias, p-hacking, harking, bad incentives, undesirable pressures and probably other factors all contribute to diminish the trustworthiness of published research, with obvious implications for research synthesis. Sergio Graziosi asks whether demanding simple theoretical clarity might be part of the solution.

BHD in patients undergoing chest CT and characteristics of BHD in Korea.

by Joana Guedes in BHD Research Blog

To date, there have been no prospective studies attempting to diagnose BHD syndrome or literature reviews on BHD in Korea. Park et al. (2017) address this in their new study that aims to detect BHD prospectively in patients undergoing chest computed tomography (CT) scans and to classify the characteristics of BHD in Korea....

A few-foods diet for ADHD: a systematic review of meta-analyses of double-blind, placebo-controlled trials

On dietary and nutritional therapies for ME/CFS

by Paul Whiteley in Questioning Answers

ME/CFS in case you don't already know refers to Myalgic Encephalomyelitis / Chronic Fatigue Syndrome and, according to the findings reported by Nadia Campagnolo and colleagues [1], is in need of quite a bit more scientific investigation when it comes to the application of dietary changes and nutritional supplements to potentially alter the course of the condition(s).Surveying the peer-reviewed literature "from 1994 to May 2016" the authors looked for peer-reviewed studies where "CFS/ME........

Timing and Attention Matter in Dog Training, New Study Shows

Analysis of videos of dog training sessions show that getting the dog’s attention and good timing of rewards are linked to better results.A new study looks at the interactions between people and dogs whilst teaching ‘lie down’. The results show the importance of the timing of rewards and of getting the dog’s attention in order to be successful in dog training.The study is part of a wider research project at the University of Sydney into what they call “dogmanship.” I asked first auth........

Sex, alcohol, and structural variants in fission yeast

by Christophe Dessimoz in Open Reading Frame

Our latest study just came out (Jeffares et al., Nature Comm 2017). In it, we carefully catalogued high-confidence structural variants among all known strains of the fission yeast population, and assessed their impact on spore viability, winemaking and other traits. This post gives a summary and the story behind the paper.

Structural variants (SVs) measure genetic variation beyond single nucleotide changes …

On atopic disease and ADHD: 'strong evidence' for an association

Biofouling successional processes

by SciELO in SciELO in Perspective | Press Releases

To assess the successional pattern of fouling organisms we tested the hypothesis that depth, light intensity and predation influences the trajectory of the fouling community. The results suggest that each physical factor or biological process can change the successional trajectory, and the respective model (e.g., convergent, divergent, parallel, or cyclic) depends on the magnitudes of the determinants that act on the community at each stage of its trajectory. … Read More →...

Natural course of "chronic disabling fatigue" in adolescents

ADHD, obesity and bariatric surgery?

by Paul Whiteley in Questioning Answers

"The findings suggest that a considerable number of patients before and after bariatric surgery screened positive for ADHD [attention-deficit hyperactivity disorder]. It can be hypothesized that some core ADHD symptoms improve after surgery."Bariatric surgery, where several surgical options are available to aid weight loss in those who present with 'dangerous' obesity, was the topic of the paper by Nielsen and colleagues [1] (open-access available here) who set out to compare "pre- and........
