Genetics of XYZ. No boundries et.al.

The scientists, led by Professor Yankner, collected brain tissue from 30 dead people (unidentified). Their ages at death varied from 26 to 106, they were also from all over the USA.

Yankner, and his team found that around 4% of 11,000 genes they identified changed significantly during a person's life span - these genes were closely linked to aging (the aging process).

The scientists wanted to identify the genes in the fontal lobe area of the brain. The frontal lobe regulates our ability to perform tasks, to organise and plan, make judgements and analyse data (information). They cut small pieces of the frontal lobe, placed then in lab dishes. The lab dishes were filled with thousands of gene markers. They could then identify the genes which were active at a given moment.

The genes are studied at 3 levels. at the level of DNAi at the level of RNA and at the protein level. The genes that are active any moment are defiened at the RNA and protein levels only.

This is a classical research outline normal and disease samples of various individuals are studied at the three levels as above.

Who knows somewhere at a corner of the worldfar away from IVY-league work somebody is working on a better tool to study these genes. The world is connected (hot, flat and, crowded) and there are no boundaries et.al. .
