Winter Outlook 2008/9

There is an important long term aspect of the Grid's Winter Outlook viz:

144. In terms of the outlook for 2008/09, with a relatively low level of wind generation in
the overall generation mix, it is not yet critical to meeting demand even in our 1 in 20
demand levels scenario that we require a significant output from wind. Demand can still
be met by other sources of generation and/or imports through the interconnector in the
event of no wind generation output at the time of peak demand. Our work over the
summer has though led us to conclude that there are challenges that we will face as GB
system operator where wind generation is a large proportion of the generation fleet and
that controllable flexible sources of generation or demand management need to be
developed in parallel with a significant expansion of the wind generation capacity. We are
already contributing to further investigation and identifying potential solutions to these
issues through our engagement with the energy industry and government.

Its the long genes that stop working

People who read my blog will be aware that I have for some time argued that most (if not all) diseases of aging are caused by cells not being able to produce enough of the right proteins. What happens is that certain genes stop functioning because of a metabolic imbalance. I was, however, mystified as to why it was always particular genes that stopped working. Recently, however, there have been three papers produced: Aging is associated with a systemic length-associated transcriptome imbalance Age- or lifestyle-induced accumulation of genotoxicity is associated with a generalized shutdown of long gene transcription and Gene Size Matters: An Analysis of Gene Length in the Human Genome From these it is obvious to see that the genes that stop working are the longer ones. To me it is therefore obvious that if there is a shortage of nuclear Acetyl-CoA then it would mean that the probability of longer Genes being transcribed would be reduced to a greater extent than shorter ones.
