Can We Reverse Aging With “Young Blood?”

Can we stave off the aging process by transfusing young blood into old people? The idea that youthful blood might have rejuvenating properties has lingered in popular imagination for centuries.

In this episode of humanOS Radio, I speak with Drs. Michael and Irina Conboy of the Department of Bioengineering at UC Berkeley. Their lab investigates the process of tissue repair throughout the body and is trying to determine why damaged tissue is not productively repaired as the body ages. In their most recent study, they discovered that molecules in aged blood may actually be interfering with the regenerative process. They are trying to identify these inhibitors, and perhaps find a way to clear them from the blood. Are we on the cusp of a breakthrough to help us stay at our peak abilities for decades longer?


Lifestyle Modifications to Extend Life by Limiting Growth

Does the ideal diet change across the lifespan? I couldn’t help circling back to this idea regularly while writing this article. In the last article on this subject of growth promotion and better aging, we discussed the concept of antagonistic pleotropy, which suggests that natural selection may favor genes that increase reproductive potential – even at the expense of long-term vitality and longevity. But can we harness an understanding of this idea to alter how we live in our post-reproductive window, to stay younger and live longer? In my latest post, I address just that – lifestyle modifications that may not only be effective to help us surviving longer, but also to live better along the way.


Does Protein Restriction and Fasting Slow the Aging Process? Better Aging Part 3

In the previous article on aging, we looked at three forms of dietary restriction: caloric restriction, prolonged fasting, and alternate-day fasting. These interventions have played an important role in providing a framework for researchers to begin unraveling the molecular details of how aging happens. But these dietary restrictions are quite extreme and are simply not practical for everyone. In this article, we will look at two less extreme forms of dietary restriction: protein restriction, and the Daniel fast.
