To me cryonics just makes sense. It may not be pretty but, just like open heart surgery, it is one of those things that, without any guarantees, can possibly extend your life [very] substantially. Thus, especially given the alternative, I just can’t quite make sense of the slow rate of adoption evident not only in North America but also across the world. And so I am always happy to discover new books that lay out the scientific argument for cryonics while making it easily digestible and giving it a very personal, human perspective. Since the most recent book, I thoroughly enjoyed on this topic was Frozen to Life: A Personal Mortality Experiment I thought that D.J. MacLennan will make an excellent guest on my podcast. I was not wrong about that.

During our 1 hour conversation with D.j. MacLennan we cover a variety of interesting topics such as: why he decided to write Frozen to Life and who is it for; cryonics as a glass-state time travel; why he chose neuro- rather than full-body preservation; the costs and rate of adoption of cryonics; the culture, conservatism and geography of his home on the Isle of Skye; transhumanism and transcending limitations; the differences between Max More and James Hughes; his fear of death; the promise of chemical brain preservation; mindfulness and meditation; writing a transhumanist take on The Wizard of Oz and potentially on Grim’s Fairy Tales…

As published in a recent study, researchers have discovered that neural stem cells are impeded by the invasion of T cells, immune cells that are not normally present in the neural stem cell niche.

The neural stem cell niches

Our brains contain neural stem cells (NSCs); like their name suggests, these cells are responsible for the formation of new neurons within the brain. This process, which continues throughout life, is known as neurogenesis. These stem cells live in particular niches, which contain a panoply of different cell types, including stem cells in different phases of development and multiple types of immune cells. However, the researchers discovered a startling fact: the brains of older mice contain many specific immune cells known as T cells, while the brains of younger mice contain very few – and, as the study explains, this is true for humans as well.

With that basic research, mankind found the first major clue to the origins of aging and death. They discovered that some cells in our bodies that may never die. These “immortal cells” and the philosophical shift in thinking they engendered, will likely change medicine as we know it.

Different African killifish species vary extensively in their lifespans—from just a few months to several years. Scientists from the Max Planck Institute for Biology of Ageing in Cologne investigated how different lifespans have evolved in nature and discovered a fundamental mechanism by which detrimental mutations accumulate in the genome causing fish to age fast and become short-lived. In humans, mutations accumulate mainly in the genes that are active in old age.

My colleague Nicola Bagalà recently had the opportunity to interview Sergey Young, a board member of XPRIZE and the creator of the $100m Longevity Vision Fund. As you probably know, at the end of May this year XPrize hosted a 2-day workshop to better understand the bottlenecks and opportunities of the longevity industry, and in this interview, Sergey is sharing his vision on what can — and should — be done to accelerate the development of new therapies addressing aging.
