Super-nanny state and the smoking ban

by Euan in Dr Euan Lawson| Doctor Writer

I don’t get too concerned about the so-called nanny state and I don’t get agitated regarding public health interventions as some infringement of my personal freedom. Maybe it’s because I’m a doctor – I am aware of my own bias here. I was delighted to see the smoking ban in public and I completely support [...]... Read more »

The Unique Case of “50 First Dates” Amnesia

by The Neurocritic in The Neurocritic

Scene from 50 First Dates with Drew Barrymore and Adam Sandler.50 First Dates maintains a venerable movie tradition of portraying an amnesiac syndrome that bears no relation to any known neurological or psychiatric condition (Baxendale, 2004).That isn't true anymore...Smith et al. (2010) have recently reported an unusual case of functional, or psychogenic amnesia in which FL, a 51 year old woman with 15 years of education and average intelligence, cannot remember what happened to her from one da........

A universal flu vaccine

by Atila Iamarino in Influenza A (H1N1) Blog – English

Will we have a universal Influenza vaccine someday? Will we find something that eliminates the need of developing a new vaccine every year and ensuring that great part of the population receives it?

The annual development of flu vaccines is a very expensive way of avoiding this disease even if it is the most efficient way. [...]... Read more »

Candidate Appearance Matters

by Wayne Hooke in The Psychology of Beauty

Appearance matters – but not in the same way for male and female political candidates. Limiting this discussion to the beauty-relevant elements of Chiao, Bowman, & Gill’s 2008 study, being attractive has an effect on rates of voting for female candidates while appearing approachable has an effect on women’s rates of voting for male candidates [...]...

How “social” is your biopsychosocial model?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

It’s called the biopsychosocial model, but how much attention do we really pay to the social part of this model? While we know the medical model has its limitations (especially when we’re looking at how people respond to having health problems), in pain management I wonder whether we now have a ‘psychological’ model of pain … Read more...

The long road to perennial cereals

by Jeremy in Agricultural Biodiversity Weblog

Why are there no perennial grain crops? That’s the provocative question posed by a recent paper in Evolutionary Applications written by three scientists working at The Land Institute. Whose institutional mission, of course, is to breed just this sort of crop, on the assumption that they “could reduce soil erosion while maintaining production of food [...]... Read more »

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 »

What happens to tuberculosis patients after treatment?

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 »

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.
