We will have a fresh new presentation on Exosomes “The End of Aging” by Harvard Genetics Genius Dr. Duncan Ross, the Founder of Kimera Labs. And Bill Faloon will present the latest in Age Reversal research.

Visit The Church of Perpetual Life this Thursday, November 21st at 7:00 PM.
Our Doors open at 6:00 PM
Before the service: Enjoy tasty snacks, networking and conversations on Age Reversal, Cryonics, The Singularity and other topics of interest to all for the quest of an Unlimited Life. Stay afterwards as we have a delicious 5 star dinner reception with speakers.

Bring a friend! Someone that you would like to share news of amazing emerging technologies on Health & Extreme Longevity!

“Our task is to make nature, the blind force of nature, into an instrument of universal resuscitation and to become a union of immortal beings.“
- Nikolai F. Fedorov

We hold faith in the technologies & discoveries of humanity to END AGING and Defeat involuntary Death within our lifetime.

Working to Save Lives with Age Reversal Education.

Cancer cells may owe some of their destructive nature to unique, “doughnut-shaped” DNA, according to a new study.

The study, published today (Nov. 20) in the journal Nature, found that, in some cancer cells, DNA doesn’t pack into thread-like structures like it does in healthy cells — rather, the genetic material folds into a ring-like shape that makes the cancer more aggressive.

Promising preliminary data from one of the first human trials testing the safety and efficacy of a CRISPR gene therapy has just been revealed. Although it is too early to evaluate long-term effects, the initial reports are impressively successful for two patients with severe genetic blood diseases.

Until February of this year, when pharmaceutical companies CRISPR Therapeutics and Vertex began a large global trial into a treatment called CTX001, no human outside of China had been officially treated with a CRISPR-based gene editing therapy.

CTX001 was developed to treat two types of inherited blood disease, beta-thalassemia and sickle cell disease. Both conditions are caused by a mutation in a single gene and the treatment involves engineering a patient’s stem cells with a single genetic change designed to raise levels of fetal hemoglobin in red blood cells.

While Intermittent fasting may sound like another dieting craze, the practice of routinely not eating and drinking for short periods of time has shown again to lead to potentially better health outcomes.

In a new study by researchers at the Intermountain Healthcare Heart Institute in Salt Lake City, researchers have found that cardiac catheterization patients who practiced regular intermittent lived longer than patients who don’t. In addition, the study found that patients who practice intermittent fasting are less likely to be diagnosed with .

“It’s another example of how we’re finding that regularly fasting can lead to better health outcomes and longer lives,” said Benjamin Horne, Ph.D., principal investigator of the study and director of cardiovascular and genetic epidemiology at the Intermountain Healthcare Heart Institute.

An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids—the parent bodies of many meteorites—can make some of life’s ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s .

The team discovered ribose and other bio-essential sugars including arabinose and xylose in two different meteorites that are rich in carbon, NWA 801 (type CR2) and Murchison (type CM2). Ribose is a crucial component of RNA (). In much of modern life, RNA serves as a messenger molecule, copying genetic instructions from the DNA molecule (deoxyribonucleic acid) and delivering them to molecular factories within the cell called ribosomes that read the RNA to build specific proteins needed to carry out life processes.

The evolution of human diets led to preferences toward polyunsaturated fatty acid (PUFA) content with ‘Western’ diets enriched in ω-6 PUFAs. Mounting evidence points to ω-6 PUFA excess limiting metabolic and cognitive processes that define longevity in humans. When chosen during pregnancy, ω-6 PUFA-enriched ‘Western’ diets can reprogram maternal bodily metabolism with maternal nutrient supply precipitating the body-wide imprinting of molecular and cellular adaptations at the level of long-range intercellular signaling networks in the unborn fetus. Even though unfavorable neurological outcomes are amongst the most common complications of intrauterine ω-6 PUFA excess, cellular underpinnings of life-long modifications to brain architecture remain unknown. Here, we show that nutritional ω-6 PUFA-derived endocannabinoids desensitize CB1 cannabinoid receptors, thus inducing epigenetic repression of transcriptional regulatory networks controlling neuronal differentiation. We found that cortical neurons lose their positional identity and axonal selectivity when mouse fetuses are exposed to excess ω-6 PUFAs in utero. Conversion of ω-6 PUFAs into endocannabinoids disrupted the temporal precision of signaling at neuronal CB1 cannabinoid receptors, chiefly deregulating Stat3-dependent transcriptional cascades otherwise required to execute neuronal differentiation programs. Global proteomics identified the immunoglobulin family of cell adhesion molecules (IgCAMs) as direct substrates, with DNA methylation and chromatin accessibility profiling uncovering epigenetic reprogramming at 1400 sites in neurons after prolonged cannabinoid exposure. We found anxiety and depression-like behavioral traits to manifest in adult offspring, which is consistent with genetic models of reduced IgCAM expression, to suggest causality for cortical wiring defects. Overall, our data uncover a regulatory mechanism whose disruption by maternal food choices could limit an offspring’s brain function for life.
