Researchers have uncovered what may be a universal cause of aging, one that applies to both single cell organisms such as yeast and multicellular organisms, including mammals. This is the first time that such an evolutionarily conserved aging mechanism has been identified between such diverse organisms.
The mechanism probably dates back more than one billion years. The study shows how DNA damage eventually leads to a breakdown in the cell's ability to properly regulate which genes are switched on and off in particular settings.
Like our current financial crisis, the aging process might also be a product excessive deregulation.
Researchers have discovered that DNA damage decreases a cell's ability to regulate which genes are turned on and off in particular settings. This mechanism, which applies both to fungus and to us, might represent a universal culprit for aging.
Comment: While comet impacts may be "much rarer" in our solar system than others, it certainly does not mean they do not strike ours. For a more enlightening and detailed study, read Forget about Global Warming, We are One Step From Extinction!
