Longevitytech.fund’s Petr Sramek on why the longevity field needs to look at the whole – and why it needs precision and personalization.

In a new paper, Sinclair and his co-authors outline a theory arguing that epigenetic changes are the underlying cause of aging [1].

It is not every day that one of the most prominent geroscientists presents a new theory of aging. David Sinclair of Harvard, along with two co-authors, Yuancheng Ryan Lu and Xiao Tian, have just published “The Information Theory of Aging” in Nature Aging. This theory was proposed by Sinclair years ago [2], and this new paper is an attempt to summarize it based on the most recent research.

The ability to store and retrieve information is central to life, which relies on the constant reproduction of complex organisms using DNA blueprints. However, on top of that digital genetic code, there is a much messier realm of epigenetics, which regulates how genetic information is translated into proteins.

Growing old may come with more aches and pains attached, but new research suggests there’s a bigger picture to look at: by reaching our dotage, we might actually be helping the evolution of our species.

Once assumed to be an inevitable consequence of living in a rough-and-tumble world, aging is now considered something of a mystery. Some species barely age at all, for example. One of the big questions is whether aging is simply a by-product of biology, or something that comes with an evolutionary advantage.

The new research is based on a computer model developed by a team from the HUN-REN Centre for Ecological Research in Hungary which suggests old age can be positively selected for in the same way as other traits.

In this episode, I am joined by Dr. David Sinclair, tenured Professor of Genetics at Harvard Medical School and an expert researcher in the field of longevity. Dr. Sinclair is also the author of the book Lifespan: Why We Age & Why We Don’t Have To, and the host of the Lifespan Podcast, which launches January 5, 2022. In this interview, we discuss the cellular and molecular mechanisms of aging and what we all can do to slow or reverse the aging process. We discuss fasting and supplementation with resveratrol, NAD, metformin, and NMN. We also discuss the use of caffeine, exercise, cold exposure, and why excessive iron load is bad for us. We discuss food choices for offsetting aging and promoting autophagy (clearance of dead cells). And we discuss the key blood markers everyone should monitor to determine your biological versus chronological age. We also discuss the future of longevity research and technology. This episode includes lots of basic science and specific, actionable protocols, right down to the details of what to do and when. By the end, you will have in-depth knowledge of the biology of aging and how to offset it. #HubermanLab #DavidSinclair #Longevity

The study found a direct correlation between specific brain rhythms during sleep and the process of memory consolidation.

Summary: Researchers unveiled a critical link between breathing and memory consolidation during sleep. In an extensive study involving EEG and breathing analysis, they discovered that specific sleep-related brain rhythms are directly influenced by our breathing patterns.

These findings highlight the importance of respiration in reinforcing learned information while we sleep. This work could have significant implications for addressing age-related memory issues and sleep disorders.

In this episode, Colleen delves into the complexity of the microbiome, how it is tested, and how it changes over time. She explores how probiotics, prebiotics, and postbiotics affect the gut and makes a compelling case that well-developed products have the potential not only to enhance gut health but also to positively influence overall metabolic well-being. Colleen emphasizes the significance of a high-fiber diet in sustaining a thriving gut microbiome, shares insights on minimizing microbiome damage during antibiotic use, provides tips for fostering and preserving a healthy gut, and much more.

Summary: A new study illuminated a part of the “dark genome,” specifically focusing on LINE-1, a genetic element linked to various diseases and aging.

Researchers have provided the first high-resolution images and structural details of LINE-1, an “ancient genetic parasite” with about 100 active copies in each person. This research, involving international collaboration, reveals LINE-1’s mechanism of integrating DNA into the human genome and its correlation with diseases like cancer and neurodegeneration.

The study’s findings offer a foundation for potential treatments targeting this retrotransposon.

But what if your longevity, healthspan, resilience and quality of life was more determined by gaining muscle than losing fat? This isn’t a bodybuilder’s coping strategy, it’s new science backed by mountains of data. Expect to learn why the quality of your life is a direct correlation to your muscle health, whether it’s more dangerous to be over-fat or under-muscled, whether exercise is more important than nutrition, Gabrielle’s favourite hacks for getting more protein in every day, whether protein timing matters, if it’s possible to achieve this with a plant-based diet and much more…
