It's often been said that those with more positive outlook are healthier, have less chance of cancer, etc. Now, for the first time, we have a mechanism for why that might be true. By monitoring activity levels in the prefrontal cortex, researchers have found that people who have more activity in the left side of this area (associated with positive emotional response) also have a stronger immune response against disease. The study involved 52 people aged between 57 and 60, and immune response was measured using flu vaccination. Brain activity was measured at a baseline state and during and after emotion eliciting memory tasks, when participants were asked to recall two events - one that made them feel intensely happy and another that left them feeling intensely sad, fearful or angry. Previous research has shown that greater activity on the right side of the prefrontal cortex is associated with a more negative outlook. Six months after being vaccinated, those who had greater activity in the left side had a greater rise in the number of antibodies for influenza.

In case you haven't discovered it, Fathom is a good resource for information on a variety of topics. There are a number of articles on memory, most of which are listed under Science & the natural world> Psychology> ... Check out the Neuroscience and Brain Research, and Cognitive Psyc sections in particular.
Here's a few I want to mention specifically:
(I hope the links work; deep links to this site seem to work better if you go to the home page first.)
an article about the aging mind from Dr Denise Park, one of the leading researchers in the effect of aging on cognitive tasks (which for some reason seems to be categorised under Global Affairs> Demography & Population)

Social psychology and memory - an extract from a classic work, Remembering, by Sir Frederick Bartlett: 

The dynamics of human memory, by the well-known neurobiologist Steven Rose:
 
Strokes, Accidents and Alzheimer's: Explaining the Human Brain

Here's a weird one. Apparently there's a rare genetic disorder called Williams syndrome. Those with this syndrome have characteristic facial and physical features, certain cardiovascular problems and mild to moderate mental retardation.
They are also markedly social, and have greater language capabilities than you would expect from their general cognitive ability. They score significantly higher on tests measuring behavior in social situations, including their ability to remember names and faces, eagerness to please others, empathy with others' emotions and tendency to approach strangers. A little girl with the syndrome who was unusually shy for a Williams child has revealed why. She was found to have retained at least one more gene from the set of genes usually missing in those with Williams syndrome.

I find this interesting for two reasons. One, of course, is the finding of a gene that has such a strong effect on sociability. The other, probably more interesting (since it has more useful implications), is the connection between these "sociable" traits, and language skills, and memory for names and faces.
