Myrtle Beach Online has a good piece on aging research and the remaining mysteries of the aging process. After an overview of current progress and what we know about aging, it's quite clear that the underlying biochemistry is very complex. There is a long way to go yet, but researchers are optimistic: "Sinclair says that research on aging is 50 years ahead of where he expected it to be when he began his work a decade ago. There's even a feeling among scientists, he says, that a Nobel Prize may be awaiting someone who finally cracks the molecular code that controls aging." Bioinformatics has dramatically accelerated aging research, just as it has for all other fields of medicine - greater funding is needed.
