Will You Live To 200? Five Levels Of Breakthroughs In Longevity Research You Must Know About

Posted by in categories: biotech/medical, life extension

As founder of Longevity Vision Fund, I am often asked about the most promising life extension breakthroughs, from early cancer diagnostics to human avatars and everything in between. The simple answer is that there are many — but that’s probably not the kind of answer you were looking for!

Instead, let’s look at the latest longevity breakthroughs working on each of the five major levels of biological organization (cell, tissue, organ, organ system and organism) and what they each aim to accomplish.

Aging fruit flies have impaired genetic responses to viral infections compared to young flies

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

In a study at The University of Alabama, aging fruit flies died faster than younger flies from a viral infection because of different genetic responses, lowering the older flies’ tolerance to the infection.

The findings published recently in G3: Genes, Genomes, Genetics add to the understanding of innate immunity, the first line of defense against infections, which is not fully understood in humans, and prove the fruit fly, Drosophila, is a good candidate for aging immunity studies that could lead to advancements in treating in older humans.

“We are living in times where there is a substantial increase in aging populations, and we know there is a decline of immune function in humans as we age,” said Dr. Stanislava Chtarbanova, UA assistant professor of biological sciences whose lab led the study. “This is the first study to use the fly for investigating age-dependent, anti-viral responses. Our lab can leverage this genetic model to study the underlying aging immunity.”

DNA building blocks regulate inflammation

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

Mitochondria are the energy suppliers of our body cells. These tiny cell components have their own genetic material, which triggers an inflammatory response when released into the interior of the cell. The reasons for the release are not yet known, but some cardiac and neurodegenerative diseases as well as the aging process are linked to the mitochondrial genome. Researchers at the Max Planck Institute for Biology of Aging and the CECAD Cluster of Excellence in Aging research have investigated the reasons for the release of mitochondrial genetic material and found a direct link to cellular metabolism: when the cell’s DNA building blocks are in short supply, mitochondria release their genetic material and trigger inflammation. The researchers hope to find new therapeutic approaches by influencing this metabolic pathway.

Our body needs energy—for every metabolic process, every movement and for breathing. This energy is produced in tiny components of our body , the so-called mitochondria. Unlike other cell components, mitochondria have their own genetic material, mitochondrial DNA. However, in certain situations, mitochondria release their DNA into the interior of the cell, causing a reaction from the cell’s own immune system and being associated with various diseases as well as the aging process. The reasons for the release of mitochondrial DNA are not yet known.

Young blood to old – where do the answers to aging lie?

Posted by in categories: biotech/medical, life extension

“After hopefully demonstrating efficacy through the pilot study, Conboy says that plans are underway for a 200–300 person, placebo-controlled Phase 3 trial to prove the use of the plasma dilution as a technology that innovatively treats co-morbidities of aging.”

This could be the first bridge.


UC Berkeley’s Irina Conboy talks parabiosis, plasma dilution, and why young blood may not hold the all answers.

New method preserves viable fruit fly embryos in liquid nitrogen

Posted by in categories: biological, cryonics, food, genetics, life extension

Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species. However, until now, the practical cryopreservation of the fruit fly (Drosophila melanogaster)—which is crucial to genetics research and critical to scientific breakthroughs benefiting human health—has not been available.

“To keep alive the ever-increasing number of with unique genotypes that aid in these breakthroughs, some 160000 different flies, laboratories and stock centers engage in the costly and frequent transfer of adults to fresh food, risking contamination and ,” said Li Zhan, a postdoctoral associate with the University of Minnesota College of Science and Engineering and the Center for Advanced Technologies for the Preservation of Biological Systems (ATP-Bio).

In new research published in Nature Communications, a University of Minnesota team has developed a first-of-its-kind method that cryopreserves fruit fly embryos so they can be successfully recovered and developed into adult insects. This method optimizes embryo permeabilization and age, cryoprotectant agent composition, different phases of nitrogen (liquid vs. slush), and post-cryopreservation embryo culture methods.
