In June, Stanford biologist Tony Wyss-Coray took the TED stage to describe no less than “an absolutely amazing development in aging research” (How young blood might help reverse aging. Yes, really). His research has shown that proteins found in the blood of younger mice can dramatically reverse the effects of aging when given to older mice. The implications are huge, perhaps ushering in a new era for the treatment of diseases like Alzheimer’s and maybe — just maybe — providing a way to treat aging itself.
But the same research has also triggered some hand-wringing, and it’s not hard to guess why. If turning back the clock on our bodies is as simple as infusing ourselves with “young blood,” won’t young blood become a commodity? And if it does, what will that mean for the world’s most vulnerable children? “I am petrified to think of the industry this would create,” wrote Todd L. in response to Wyss-Coray’s talk. “Think of how third-world children are treated now for inexpensive electronics and clothes. They would be treated like cattle to have their plasma harvested.”
