- The insertion of artificially-synthesised DNA into a bacterial cell with subsequent establishment of viability has been widely reported in the media (see here, here, here, here and here) and will lead to substantial debate about the ethical implications as well as leading to a vast array of applications. An interesting soundbite from Venter’s presentation is
‘This is the first self-replicating species that we’ve had on the planet whose parent is a computer‘
- One research group has identified a novel pathway involving amyloid plaque mediated excitotoxic cell death in a model of Alzheimer’s Disease which may lead to new therapeutic approaches.
- There is evidence that build up of Amyloid Beta leads to cataracts in people with Down Syndrome as well as being associated with early onset of Alzheimer’s Disease.
- One group has identified details of Lithium mediated anti-inflammatory pathways which may contribute to an understanding of Lithium’s mechanism(s) of action.
- Further research shows an association between adult central adiposity and later life dementia in this study of community residents (n=700).
- The authors of this study have called for psychiatrists to be included in ‘disaster first-response’ teams on the basis of their findings.
- A JAMA paper outlines details of a successful suicide reduction program in people with depression. In this population, the suicide rate was reduced by 75% and over a 2.5 year period was 0.

- The American Society of Human Genetics has produced an important position paper on genetic ancestry and this is discussed at the Genetic Genealogist blog. An excerpt reads:-
‘Leadership of the human-genetics community, diverse in its interests and its own identities, should develop mechanisms for promoting thoughtful and rigorous use of genetic ancestry estimation in academic research….Leadership of the human-genetics community, diverse in its interests and its own identities, should develop mechanisms for promoting thoughtful and rigorous use of genetic ancestry estimation in academic research’
