Sergey Young: breaking the barrier of maximum lifespan

Posted by in categories: biotech/medical, life extension, robotics/AI

The news we like: “In five to 10 years time from now, we’ll have a new, special kind of drugs: longevity drugs. And unlike today’s medication, which always focused on one disease, this kind of drug will will give us an opportunity to influence aging as a whole and a very fatalistic way, working on healthspan, not only on lifespan… it’s very likely that this new drug will be developed with the help of artificial intelligence, which will compress drug development cycle by two or three times from what they are today.”


Ahead of the launch of his new book Growing Young, Sergey Young joins us for a video interview to discuss longevity horizons, personal health strategies and disruptive tech – and how we are moving towards radically extending our lifespan and healthspan.

Sergey Young, the longevity investor and founder of the Longevity Vision Fund is on a mission to extend healthy lifespans of at least one billion people. His new book, Growing Young, is released on 24th August and is already rising up the Amazon charts.

George Church on Gene Therapies and Longevity

Posted by in categories: biotech/medical, genetics, life extension

“Balancing that, I clearly state that my goal is not longevity, not even modest longevity. It’s just reversal of diseases of aging, which really is classic medicine. Q: Which takes me to the next question: do we even know how to aim at life extension? I don’t think we do. I think if we get serious aging reversal, it’s something that we can continue to improve on, just like we improved on transportation from the first wheel to rocket ships,” I’ll be honest, I disagree as we have some improvement in humans indicated from TRIM and TAME and plasma filtering. Church’s work is very important though.


Professor of Genetics at Harvard Medical School and one of the most prominent geroscientists, George Church works on gene therapies that can potentially reverse age-related diseases. We had the opportunity to interview this prolific researcher and entrepreneur, who is involved in dozens of startups on topics ranging from the current state of gene therapy to his recent attempt to auction off his genome, one of the first sequenced human genomes in the world, as an NFT.

What have been the successes and the failures of gene therapy in recent years? What do you expect to happen in the next few years?

Stem Cell Scientists Explore the Latent Regenerative Potential of the Inner Ear

Posted by in categories: bioengineering, biotech/medical, genetics, life extension

“Our study raises the possibility of using therapeutic drugs, gene editing, or other strategies to make epigenetic modifications that tap into the latent regenerative capacity of inner ear cells as a way to restore hearing,” said Segil. “Similar epigenetic modifications may also prove useful in other non-regenerating tissues, such as the retina, kidney, lung, and heart.”


Scientists from the USC Stem Cell laboratory of Neil Segil have identified a natural barrier to the regeneration of the inner ear’s sensory cells, which are lost in hearing and balance disorders. Overcoming this barrier may be a first step in returning inner ear cells to a newborn-like state that’s primed for regeneration, as described in a new study published in Developmental Cell.

“Permanent hearing loss affects more than 60 percent of the population that reaches retirement age,” said Segil, who is a Professor in the Department of Stem Cell Biology and Regenerative Medicine, and the USC Tina and Rick Caruso Department of Otolaryngology – Head and Neck Surgery. “Our study suggests new gene engineering approaches that could be used to channel some of the same regenerative capability present in embryonic inner ear cells.”

People who live to 100 have unique gut bacteria signatures

Posted by in category: life extension

The findings suggest that isoalloLCA may contribute to a healthy gut by preventing the growth of bad bacteria.

They also suggest that these bacteria or their bile acids could treat or prevent C. difficile infection in people, Honda said, although more research would be needed to show this.


These bacteria could contribute to a healthy gut and, in turn, healthy aging.

Centenarians have unique gut bacteria that enables them to live longer

Posted by in categories: biotech/medical, food, life extension

TOKYO — Centenarians have unique gut bacteria that enables them to live to a ripe old age, according to new research. Scientists in Japan say this unique gut makeup fuels bile acids that protect against disease.

The discovery could lead to yogurts and other probiotic foods that increase longevity.

“In people over the age of 100, an enrichment in a distinct set of gut microbes generate unique bile acids,” says lead author Professor Kenya Honda of Keio University in a statement per South West News Service. “They might inhibit the growth of pathogens.”

Small proteins discovered to be regulators of the aging process

Posted by in categories: food, life extension

Scientists have discovered that the protein ubiquitin plays an important role in the regulation of the aging process. Ubiquitin was previously known to control processes such as signal transduction and metabolism. Prof. Dr. David Vilchez and his colleagues at the CECAD Cluster of Excellence for Aging Research at the University of Cologne performed a comprehensive quantitative analysis of ubiquitin signatures during aging in the model organism Caenorhabditis elegans, a nematode worm broadly used for aging research. This method—called ubiquitin proteomics—measures all changes in ubiquitination of proteins in the cell.

The resulting data provide site-specific information and define quantitative changes in changes across all proteins in a cell during aging. A comparison with the total content of a cell (proteome) showed which changes have functional consequences in protein turnover and actual protein content during aging. The scientists thus discovered new regulators of lifespan and provide a comprehensive dataset that helps to understand aging and . The article, “Rewiring of the ubiquitinated proteome determines aging in C. elegans,” has now been published in Nature.

“Our study of ubiquitin changes led us to a number of exciting conclusions with important insights for understanding the aging process,” said Dr. Seda Koyuncu, lead author of the study. “We discovered that aging leads to changes in the ubiquitination of thousands of proteins in the cell, whereas longevity measures such as reduced food intake and reduced insulin signaling prevent these changes.” Specifically, the researchers found that aging causes a general loss of ubiquitination. This is caused by the enzymes that remove ubiquitin from proteins become more active during aging. Normally, ubiquitinated proteins are recognized and destroyed by the proteasome, the cell’s garbage truck. The scientists showed that the longevity of organisms is determined by age-related changes in the degradation of structural and regulatory proteins by the proteasome.

Gerostate passes crowdfunding goal for antiaging drug platform

Posted by in categories: biotech/medical, life extension

With around two weeks still remaining in its crowdfunding campaign, Buck Institute incubated start-up Gerostate Alpha has cruised through its minimum funding target of $300000. The company also revealed that Longevitytech.fund has joined the round as a lead investor, bringing the total investment in the company to more than $500000 so far.

“At Longevitytech.fund, we invest in start-ups focused on aging that will materially ‘move the needle,’” says the investment firm’s managing partner, Petr Sramek. “The team at Gerostate Alpha is poised to do just that in the coming years, and we are very excited to partner with them for the long haul.”

Longevity. Technology: For early stage biotech companies, particularly those targeting aging, securing funding is a constant challenge. Gerostate Alpha is “testing the water” by exploring crowdfunding as another financing option, and seems to have had some success with it. We caught up with the company’s co-founders Simon Melov and Mark Lucanic to find out more.

The effect of high intensity interval training on telomere length and telomerase activity in non-athlete young men

Posted by in categories: biotech/medical, life extension

Exercise: Good for your mind, body, and telomeres!


Introduction: Telomeres are DNA portions that are located on the two ends of the chromosome. Telomeres play an important role in cellular life. Exercise is one of the factors that contributes to their control. The purpose of the present study was to investigate the effect of 8 weeks of high intensity interval training (HIIT) on telomere length and telomerase activity in non-athletic young men. Materials and methods: 30 inactive students were selected as sample and randomly divided into two groups of exercise (15 people) and control (15 people) in this semi-experimental study. The exercise group performed 8 weeks of HIIT exercise in 3 sessions per week with an intensity of 150 to 175% of their maximum power (Pmax). Control group subjects did not do regular sport activities. To measure telomere length and telomerase activity, 10 ml of blood was taken from the brachial vein of the subjects 24 hours before the first and after the last exercise session. The dependent t was used to analyze intra-group and independent t for within-group differences. Results: The findings of this study showed that 8 weeks of HIIT training in non-athlete young men resulted in a significant increase in telomere length (P = 0.001) and telomerase activity (P = 0.001). Conclusion: It seems that HIIT can alter telomerase activity and telomere length. Therefore, these training may have a positive effect on cell biology.
