Differentiating between autism and ADHD the machine learning way (again)
by Paul Whiteley in Questioning Answers
So: "These results support the potential of creating a quick, accurate and widely accessible method for differentiating risks between ASD [autism spectrum disorder] and ADHD [attention-deficit hyperactivity disorder]."That was a conclusion reached in the paper by Marlena Duda and colleagues [1] (open-access) building on their previous foray into this important research area (see here). Last time around [2] this research group - the Duda/Wall et al research combination - set t........ Read more »

D10 in the Treatment of Prehospital Hypoglycemia: A 24 Month Observational Cohort Study
by Rogue Medic in Rogue Medic
Why treat hypoglycemia with 10% dextrose (D10), rather than the more expensive, potentially more harmful, and less available traditional treatment of 50% dextrose (D50)? Why not? The only benefit of 50% dextrose appears to be that it is what people are used to using, but aren't we used to starting IVs (IntraVenous lines) and running fluids through the IVs? ... Read more »

Cities Are Bad for Bumblebees—Except Detroit
by Elizabeth Preston in Inkfish
For bumblebees, big cities are a bummer. Layers of?asphalt, concrete, brick and metal add up to?fewer places for the insects to nest. But one big city—Detroit—reverses that trend. That means shrinking cities might be a growing opportunity for at-risk pollinators.
Bumblebees (species with?the genus name?Bombus) are, like other bees, in trouble. Their numbers and diversity are decreasing across North America. Other native wild bees—the insects that have been living here and pollinatin........ Read more »

Your best bet for an expert witness is a friendly nerd rather than an attractive scientist

And it doesn’t really matter if the expert is male or female, if they are young or old, and they can be any ethnicity! In other words, said the researchers—the variables we have read so much about (i.e., gender, age, ethnicity) are not as notable as whether someone “looks like” our stereotype of a “good […]...

On migration status and offspring autism severity
by Paul Whiteley in Questioning Answers
"Black women from East Africa had more than 3.5 times the odds of autism spectrum disorder with intellectual disability in their children than Caucasian nonimmigrant women."So said the study results reported by Jenny Fairthorn and colleagues [1] (open-access available here) providing yet more evidence for the need for much greater scrutiny as to why children of immigrant parents from East Africa are seemingly at higher risk of 'more severe' autism than other groups (see here and see here).B........

Unattractive People Are Seen As Better Scientists

Good looking, sociable people don't make good scientists, according to popular stereotypes.
This is one of the findings of an interesting new study of how scientists are perceived, from British researchers Ana I. Gheorghiu and colleagues.
Gheorghiu et al. took 616 pictures of scientists, which they downloaded from the faculty pages at various universities. They gave the portraits to two sets of raters. The first group were asked to rate the attractiveness of the portraits and to say whet... Read more »

The Ugliness Penalty: Does It Literally Pay to Be Pretty?
by Melissa Chernick in Science Storiented
There are economic studies that show that attractive people earn more money and, conversely, unattractive earn less money. I’m pretty sure that I’ve heard something along those lines before, but I had no idea they were called the “beauty premium” and the “ugliness penalty.” How wonderful and sad at the same time. But while these seem like pretty commonplace ideas, there is no real evidence as to why they exist. A new paper published in the Journal of Business and Psychology tested th........ Read more »

The PI3K/mTOR inhibitor GSK2126458 is effective for treating TSC solid renal tumours
by Joana Guedes in BHD Research Blog
Tuberous sclerosis (TSC) is an inherited tumour syndrome that shares clinical similarities with Birt-Hogg-Dube Syndrome. It is caused by mutations in TSC1 or TSC2 that lead to aberrant activation of mTOR, affecting multiple organs, including the kidney and lung. In the kidney, lesions such as multiple renal cysts and renal cell carcinoma (RCC) can occur. Tumour reduction in TSC patients after treatment with rapamycin, an inhibitor of mTOR, is partial and reversible probably due to feedback activ........ Read more »
