Should you worry about vitamin D deficiency? Maybe. Or maybe not.
Since my last blog post, where I shared my thoughts on BRCA1, BRCA2, and preventive mastectomies, I've been asked what else can a woman do to reduce her risk of breast cancer. I've heard a big deal about vitamin D, so I did a bit of research on the matter. As a disclaimer, I should tell you up front that, though many correlations between vitamin D deficiency and cancer risk have been found, just as many have been refuted or found inconclusive. You can read more about it on the wikipedia page.Wha........ Read more »

New Reliable Blood Test Can Detect Depression
by Pieter Carriere in United Academics
Depression or Major Depressive Disorder (MDD) has multiple genetic and environmental causes. Genetic factors are hard to find and the discovered factors usually are also associated with other mood disorders. Furthermore, twin studies reveal that genetics can predict 37% of the depressions, which is a much lower heritability than in bipolar disorder, a comparable mood disorder (reviewed in Belmaker et al., 2008). ...

The mindbus technique for resisting chocolate - should we climb aboard?

Imagine you are the driver & your chocolate cravings are unruly passengers
If someone gave you a bag of 14 chocolates to carry around for five days, would you be able to resist eating them and any other chocolate? That was challenge faced by 135 undergrads in a new study that compared the effectiveness of two different "mindfulness" resistance techniques.
To help them, Kim Jenkins and Katy Tapper taught 45 of their participants "cognitive diffusion", the essence being that "you are not y........ Read more »

Big data for autism and the promise of newborn bloodspots

An episode of the BBC program Horizon on 'Big Data' recently caught my attention.

Dogs can haz brainscanz and EEG?
by CAPB in Companion Animal Psychology Blog
Canine cognition is a hot topic these days, using experiments and brain imaging as research tools. The trouble with brain imaging work is that it is invasive, to the extent that animals may have to be sedated or anaesthetized for the study. All that changed with the amazing work of Gregory Berns et al and the first-ever fMRI study on awake, unrestrained dogs last year. Now Miiamaaria Kujala et al in Finland have shown that it is also possible to do a non-invasive EEG with dogs.An EEG measur........ Read more »
