Is it an impossible dream to find Ponce de Le贸n鈥檚 Fountain of Youth? No! I鈥檝e just attended my 67th reunion at the Harvard Medical School and, while interviewing Dr. George Church, I discovered such a notion is no longer science fiction.
Dr. Church, professor of genetics at the school and one of the world鈥檚 great scientists, predicts we are about to end the aging process 鈥� in the next five years, no less. That鈥檚 why I say: 鈥淒amn it, I was born too soon.鈥�
Is Church too optimistic? Maybe, but when you see his six-foot-five frame towering over you, with his white beard, it鈥檚 like talking to Charles Darwin, or even Jesus Christ.
Just walking through Church鈥檚 huge laboratory is an awesome experience. The research facility has more than 100 researchers, and you know inherently something very special is happening.
Church claims our aging population is one of our major health problems. He explains that, if all our grey hairs could be rejuvenated, the discovery would keep people working, averting an economic disaster.
So how is he going to achieve this? It鈥檚 a complicated technique. But basically, it is by creating molecular scissors that enable researchers to cut, edit and reprogram our DNA.
Genes are part of our DNA and genes determine the colour of our eyes, our sex, intelligence, in fact just about everything.
During this editing, cells that cause unfavourable genetic changes are removed. Church says that once this technique is perfected, old cells may be rejuvenated and will never age again.
Church鈥檚 molecular engineering is being carried out on animals. One project is to genetically engineer mice on the Massachusetts islands of Nantucket and Martha鈥檚 Vineyard that would eliminate Lyme disease. The researchers have also altered pig genes so that their organs can be transplanted into patients without being rejected.
Another godsend of Church鈥檚 research is the ability of doctors to eradicate the genes that cause cystic fibrosis and other genetic diseases that condemn patients to a life of hell or early death.
Church is also turbocharging genetic engineering that may result in cures for cancer and better food crops. He says it will not be too long before you can fuel up your car without worrying about polluting our planet. Rather, fuel will come from microbes that have been genetically altered to produce biofuel. Like any genius, Church has critics. They say he is playing God.
But Church insists he is simply re-engineering cells, and this is what distinguishes us from animals.
Does he worry about the implications of genetic engineering? He answers with a big 鈥淵es.鈥� But he adds: 鈥淭here is a dark side to everything in life. After all, cars kill people every year, but we don鈥檛 stop producing them.鈥�
Ting Wu, Church鈥檚 wife, also a Harvard geneticist, says her husband exhibits a huge sense of responsibility. Church makes sure the public is aware of the research he is doing, she says.
I asked Church if this will mean the end of babies if no one dies, and what about overpopulation? But he says there is still ample land and even suggested the possibility of people sharing children.
As I left his laboratory, I was convinced critics will never end their cry that he is playing God, but that his research will be a blessing for those with genetic defects. That science always wins, as you cannot stop progress. And what a pleasure it was for me to have interviewed a scientist who is destined for the Nobel Prize. And I wished fate had postponed my birth a few more years.
Return visits to Harvard Medical School are now emotional for me, as few of my classmates are alive. Inevitably, I recall the first time I arrived there. It was a beautiful night, with a full moon shining on five stunning white marble buildings. I knew then, as I know now, that incredible achievements would emerge from that institution.
I couldn鈥檛 believe I鈥檇 been accepted as a student. Nor did I realize I would be fortunate to spend most of my surgical training at the school. Or that aging would be eradicated there.
Harvard鈥檚 motto is 鈥淭ruth.鈥� In the 41 years I have written this column, I have kept that word in mind.
