Using a barometer to measure height

Normal Physics exam questions involve measuring the pressure at the two heights to work out how tall a building is.

Alternatively if you want to compare heights of two children you can place a barometer on their heads thus:

This answers the question as to whether my 12 year old son is now taller than my 15 year old daughter (who is 5'10").

Been fighting the cat for custody of the drinks cabinet again, John?

Most of us cope quite well with the marks on a doorframe method.

Happy Christmas, anyway and may 2006 bring Labour back to power in Birmingham. Lord knows, the place needs us back.

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.
