Female Teachers’ Math Anxiety Negatively Affects Female Students

by Shaheen Lakhan in Brain Blogger

For a long time it was believed that males have better spatial and numerical abilities resulting in their greater aptitude for mathematics compared to females. But research in cognitive development of human infants and children has failed to support these claims. Instead, scientists now have enough evidence to conclude that the same set of biologically [...]... Read more »

Whole Grains in Diabetics: A Double-Edged Sword

by Steve Parker, M.D. in Diabetic Mediterranean Diet Blog

 Whole grain and bran consumption are linked to reduced overall death rates and cardiovascular disease deaths in white women with type 2 diabetes, according to recent research from Boston-based investigators. This is an important association since diabetics are prone to develop cardiovascular disease and suffer premature death.  Anything that can easily counteract those trends is welcome. Several prior [...]... Read more »

Methods of sampling and analysis and our concepts of ocean dynamics

by Sam in Oceanographer's Choice

I read a paper today (actually, more like an essay) by Peter Wangersky, a longtime chemical oceanographer. Titled “Methods of sampling and analysis and our concepts of ocean dynamics,” it is essentially a personable ramble through six decades of marine science, reflecting on the technical capabilities and sampling methods over time and the [...]...

What happens to tuberculosis patients after treatment?

by Bernt Lindtjorn in International Health Research


Mortality in successfully treated TB patients is an important measure of the efficacy of treatment. However, there is no routine monitoring of TB patients after treatment completion to understand what happens to them after successful treatment for tuberculosis. We recently did a study in rural south Ethiopia to measure mortality in TB patients after they [...]... Read more »

Structural Causes of Increasing Life Expectancy

by Reason in Fight Aging!

As I'm sure you're all aware by now, human life expectancy for both young and old in the most developed regions of the world is slowly increasing, and this has been the case for some time. As medical technology advances and our wealth grows, we benefit in ways that lead to less biochemical damage to the complex machinery of our body accumulated over the course of a lifetime - and thus a greater likelihood of living longer. That the medical and research establishments have achieved this ongoing b........ Read more »

The overall pattern of the results shows that students of less experienced and less qualified professors perform significantly better in the contemporaneous course being taught. In contrast, the students of more experienced and more highly qualified introductory professors perform significantly better in the follow-on courses.... Read more »

Humans in the Philippines 67,000 years ago

by Julien Riel-Salvatore in A Very Remote Period Indeed

So say Mijares and colleagues (2010), reporting the discovery of a small human third metatarsal from Callao Cave in the northern Philippines. The paper present a brief overview of fieldwork conducted at Callao since 2003 that exposed Pleistocene deposits at the site. The age of the layer in which the metatarsal was recovered was obtained through Electron Spin Resonance (ESR) and Uranium Series (U-Series) on two cervid teeth, one of which yielded an age of 66 +11/-9 kya.From Mijares et al. (2010:........ Read more »

Melatonin Effective for Insomnia in Children with Autism Spectrum

by William Yates, M.D. in Brain Posts

Sleep problems commonly complicate the management of autism spectrum in children and adults. Behavioral therapy for insomnia can be effective, However, many fail to respond to behavior therapy and clinicians then consider drug treatment options.Wright and colleagues from the UK conducted a clinical trial of melatonin in children with autism spectrum and severe sleep problems. The children in this study failed a behavioral intervention prior to beginning the drug study. This study was remarka........ Read more »

Research on DNA ends could lead to a blood test to monitor leukaemia

by Cancer Research UK in Cancer Research UK - Science Update

Our cells are dividing all the time – replacing worn-out cells and healing injuries. But cell division can be a tricky business – every time a cell divides, each one of its 46 chromosomes, and the DNA they are made of, must be copied perfectly. Time and time again the cells in our bodies divide [...]... Read more »

Leonardo da Vinci – Paleontology Pioneer

by Brian Switek in Dinosaur Tracking

Although he’s been dead for nearly 500 years, Leonardo da Vinci is still remembered as the quintessential Renaissance man, a polymath whose curiosity and creativity ranged widely among the arts and sciences. One of his interests was the study of fossils. In a new paper in the journal Palaios, Andrea Baucon shows that he was [...]... Read more »

More evidence for a genetic basis for most autism

by Orac in Respectful Insolence

I wonder what the loons at Age of Autism will say about this.

Actually, I know what they'll say. Whenever a scientific study like the one just published earlier this week the top tier journal Nature, which examines genetic variations (CNVs) associated with autism and autism spectrum disorders (ASDs), comes out, they have a standard reply. Even though, as of this writing, I haven't seen yet seen a reply on the anti-vaccine crank blog Age of Autism to the study I'm about to describe, I'm sure it'........ Read more »

A Bonobo in the Hand or Two Chimps in the Bush?

by Jason Goldman in The Thoughtful Animal

Bonobo Week continues! I'm donating whatever proceeds I receive from my blogging shenanigans for the entire month of June to help the bonobos at Lola Ya Bonobo.

Imagine that you're wandering in the desert and you come across two magic lamps. One lamp grants three wishes. It's your standard sort of magic lamp with a genie in it. (No wishing for extra wishes, of course.) The second magic lamp is, well, a moody magic lamp. It's inconsistent. Sometimes it grants one wish, and sometimes it grants se........ Read more »

Say Cheese! Big smilers in photos are likely to live longer

by BPS Research Digest in BPS Research Digest

Look at a person's photo and it's tempting to think you can see their personality written on their face: some stony-faced individuals appear somber, others are flashing a big, toothy grin. An intriguing new study claims that these smiles are a reliable marker of underlying positive emotion and as such are predictive of a person's longevity.Ernest Abel and Michael Kruger had five people rate the smile intensity of 230 baseball players according to photos featured in the 1952 Baseball Register.

What's this psychopathy hoo-ha all about?

by BPS Research Digest in BPS Research Digest

A psychology paper by David Cooke and Jennifer Skeem critical of the dominant tool for measuring psychopathy has finally been published after years lying dormant. The delay, according to reports, was due to threats of libel by lawyers representing Robert Hare, author of the criticised tool. Curiously, back in 2007, when the contentious paper was first moth-balled, a similar and related paper (free to access), also by Cooke and Skeem, plus statistician Christine Michie, was published in the Briti........

What is a “neurodevelopmental disorder”?

by Kevin Mitchell in Wiring the Brain

This question arose at the recent, excellent meeting of the International Society for Developmental Neuroscience in Estoril, Portugal.  The question came up due to some very exciting and very unexpected successes in reversing in adult animals the effects of mutations causing neurodevelopmental disorders, including neurofibromatosis, Down syndrome, Rett syndrome and tuberous sclerosis.  All of these disorders are caused by specific genetic lesions and characterised by very early deficits, va........
