There is an interesting study (via @claudiamegele) about the genetics of Depression. A study involving an international collaboration of 86 scientists looking at studies with a cumulative total of 34, 549 participants found no strong genetic links to Depression. There are various studies which show there can be a strong family history of Depression but these most recent findings suggest important lessons are yet to be learnt in understanding the relationship between genetics and unipolar Depression.

The Bystander Effect occurs when a person observing a person in distress is less likely to act in the presence of other observers. There is also evidence that the likelihood of a response diminishes as the number of other observers increases.  One team at University College London investigated this phenomenon using virtual reality. They found that people were more likely to react in the environment to a virtual character appearing to be in distress if the character had a similar affiliation to themselves or if the character appearing in distress looked directly at them.

A variation of the Dopamine gene has been found to be associated with longevity in one study. The gene variant (allele) known as DRD4 7r allele was investigated in people aged 7-109 years of age. Those people aged 90-109 years (n=310) were 66% more likely than the younger age (7 -45 years of age, n=2902) to have this allele. The researchers also undertook research into mice which corroborated these findings

There is an interesting writeup at the Well blog at the New York Times on animals studies showing that mood and memory gains from exercise can be lost after periods of inactivity. However this shouldn’t be too surprising if exercise promotes memory and mood.

The Medical Research Council have a fascinating piece on the pioneers of Magnetic Resonance Imaging including an early photograph of the team featuring Sir Peter Mansfield.

PLOS-One have an interesting paper on a study looking at how metaphors influence decision making. The researchers in this study gave subjects a problem to solve and examined the effects of metaphor use on decision-making by the subjects. The researchers found evidence for metaphor influencing decision-making. The researchers found that even if subjects did not have an explicit memory of the metaphor it still influenced their decision making.

Evolutionary Psychiatry

The strength of Chimpanzees relative to humans is covered in this article.

There is an interesting write up on the debate about the possible ‘mind reading’ abilities of Crows.

One group has developed a gene chip looking at SNP’s (Single Nucleotide Polymorphisms). These are short gene sequences. This gene chip is being used to identify specific traits in people with a high degree of confidence.
