Testosterone: An Antidote to Aging?
Testosterone, the most important of the male sex hormones, has been both touted and blamed for the critical role it plays in making men men. It has been praised for building muscle, fueling a healthy libido and maintaining energy levels. It has also been faulted for making some men overly aggressive. But the level of testosterone peaks in a man's body in his 20s and gradually declines with age. Can it get too low and what happens if it does? Should he consider testosterone replacement therapy (TRT)? To find out more about this testosterone deficiency and its treatment, we spoke with Dr. Lisa Tenover, a geriatrician at Emory University who studies the effects of hormone replacement in men age 65 and older.
Decoding the Human Genome: Mapping the Future of Health and Aging
Science in the Spotlight
Picture your annual medical check-up, sometime in the future. You stop by your doctor's office and with a quick prick of the needle, you provide a tiny drop of blood. That's it, you're done. Thanks to advances in genetic research, gene-based diagnostic tests on that one drop of blood will provide far more information about the state of your health than a battery of tests do today. Sound far-fetched? Well, it may be closer than you think. Earlier this year, scientists successfully mapped the entire human genome for the first time—a research advance that experts predict will make possible this advanced diagnostic tool, along with cures for most diseases and ways to dramatically control the aging process.
Lost Opportunities on the Campaign Trail: Candidates Ignore Impending Senior Boom and its Dramatic Impact on Society
Get Mad Column
Something momentous is about to happen in this country. The largest generation in American history is poised to move into retirement, creating an unprecedented "senior boom." By 2030, there will be an estimated 70 million people over the age of 65, twice as many as there are today.
Championing Human Genome Research: We Need to Keep Urging for Increased Public Support for Research
With all the publicity surrounding the recent mapping of the human genome, it's hard to believe the project was ever less than wildly popular. However, like many other major scientific advances before it, this undertaking initially needed voices to speak out in its support.
Dr. Jack McConnell: Transforming Health Care, His Community, and Himself
When he retired to the beach after an illustrious biomedical research career, Jack McConnell, M.D. — integral to such advances as the tuberculosis test, Tylenol, and magnetic resonance imaging — tried to be "what they call a typical retiree: play golf, eat at restaurants and travel."
