The study is part of an effort by entrepreneurs and scientists, dreamers and schemers, to demonstrate aging is not inevitable.

Low-Carb Diets for Longevity
Posted in life extension
Can low-carb diets like Keto help you live longer? I spent way too much time reading research papers and the answer seems to be…maybe.

I love bacon.
On a beach trip with some college friends a few years ago, I was put in charge of breakfast. I made sure to buy eight pounds of bacon (one for every person on the trip) for our three days at the beach house.

Emmy award winning television commentator, radio personality, and newspaper columnist, juan williams, talking about inter-generational dynamics, ageism, and aging in america.
Progress, Potential, And Possibilities has the honor of being joined today by Emmy Award winning Television Commentator, Radio Personality, and Newspaper Columnist, Mr. Juan Williams.
Mr. Williams has been a Fox News Contributor since 1997 (including being a member of the nightly, current issue discussion show known as The Five), writes for several newspapers including The Washington Post, The New York Times, and The Wall Street Journal, and has been published in magazines such as The Atlantic Monthly and Time.
Mr. Williams was a senior news analyst for National Public Radio for 11 years and was at The Washington Post for 23 years, working as an editorial writer, op-ed columnist, White House correspondent and national correspondent.
Mr. Williams is an accomplished author with multiple books including Thurgood Marshall: American Revolutionary, Eyes on the Prize: America’s Civil Rights Years, and We the People: The Modern-Day Figures Who Have Reshaped and Affirmed the Founding Fathers’ Vision of America.
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 cells, 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.
“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.
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 fruit flies 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 genetic drift,” 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.
All brains shrink with age, and the dominant view has been that more education slows the rate of shrinking. However, the evidence has been inconclusive because studies have not been able to track the rate of change over time. Until now.
Measured brain shrinkage over time
A team of researchers measured brain aging by measuring the volume of the cortical mantle and hippocampus regions of the brain, in MRI scans from more than 2000 participants in the Lifebrain and UK biobanks. These areas of the brain are prone to shrinkage over time, as a natural part of aging. Participants’ brains were scanned up to three times over an 11 year period, in what is known as a ‘longitudinal’ study.

Ms. Anja Krammer, CEO of Turn Biotechnologies talks about the initial targets for ERA, the time line for clinical trials and FDA approval.
Turn Bio was co-founded by Dr. Vittorio Sebastiano to develop and market the Epigenetic Reprogramming of Aging technology that came out of his lab in Stanford University.
Ms. Krammer is a veteran of F500 healthcare and technology companies and co-founder of three Silicon Valley start ups. She is an entrepreneur who has built biotech, pharmaceutical and consumer businesses by assembling high-performance, results-driven teams and a counsellor to multiple enterprises, who has served on boards of public and private companies, industry organizations and foundation.
