The cells are critical building blocks of our body. How and why cells age, lose their ability to function and reproduce and ultimately die may help us understand the causes (and perhaps the cures) for many age-related diseases and conditions.

Can anti-oxidants prevent cell damage, disease and aging?
Is there a genetic clock for aging?
Are breakdowns in our genetic repair system responsible for aging?
Does injury to mitochondria - the cell's powerhouse - cause aging?
Do stem cells offer a viable strategy for confronting the aging process?
What causes cells to age?

Researchers are exploring several big questions about the aging process. Are there genes that grant us longevity? Can a drastically reduced diet improve and lengthen our lives? Can we learn something about human longevity from simple organisms like worms or fruit flies?

How do we age?
Can cutting calories increase longevity?
Are there genes that can help us live longer?
What does research on other animals and organisms tell us about the human aging process?
What does the mapping of the human genome mean for aging research?
How does the brain change with age?
What might new cloning technologies mean for fighting age-related diseases and confronting the aging process?
Are there tests that can predict how long a person will live?
Are there new vaccines and other immunological strategies that may help us ward off the disease of aging?
