Refining the Epigenetic Clock

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

A team of researchers, including professor Steve Horvath, the pioneer of the epigenetic clock, report in this new paper about an improved version of that clock [1]. His original epigenetic clock measures the age of a person by looking at DNA methylation patterns; these patterns correlate closely with the actual age of a person, with a margin of error of around two years or so.

Since the original clock was first created, work has continued on refining the process and how aging is measured. In terms of aging biomarkers, it is generally considered the gold standard, given how reliable it is as a way to determine biological age.

While chronological age is linked to the likelihood of us developing age-related diseases and dying, it is important to distinguish the difference between chronological age and biological age. Individuals of the same chronological age may not age in quite the same way or even at the same rate, showing differences in their susceptibility to different age-related diseases.

Undoing Aging with Keith Comito

Posted by in categories: biotech/medical, life extension

An interview from the recent Ending Aging conference in Berlin with Keith Comito which we did in collaboration with Anna Dobryukha from Komsomolskaya Pravda.


The Undoing Aging conference, a collaboration between the SENS Research Foundation and Michael Greve’s Forever Healthy Foundation, took place on March 15–17 in Berlin, which saw many researchers, advocates, investors, and other important members of the longevity community gather together to learn about the latest progress in rejuvenation biotechnology.

As we had arranged a travel grant for Anna Dobryukha, one of the best Russian journalists writing about aging, longevity, and rejuvenation research, to join us, it made sense to collaborate with her on the most interesting interviews. Anna works for Komsomolskaya Pravda, one of the largest Russian publishing houses, which has a newspaper, a radio station, and a website with over 40 million readers. Anna has also published an article based on this and other interviews taken during the conference which you can find here.

Stem Cell Implants in the Brain Could Delay Aging

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

Scientists at New York’s Albert Einstein College of Medicine have conducted experiments and found that stem cell implants in the brains of mice can stop aging and help the treated animals remain fitter for longer.

What part of the brain controls aging?

The experiments have helped researchers identify that a part of the brain called the hypothalamus is intimately involved in the aging process. The investigators hope to launch trials in humans to see whether similar treatments with neural stem cells can prolong the life of treated individuals.

Researchers use CRISPR to edit DNA outside of the cell for the first time

Posted by in categories: bioengineering, biotech/medical, genetics, health

Wilmington, DE, April 19, 2018 — Scientists at Christiana Care Health System’s Gene Editing Institute have developed a potentially breakthrough CRISPR gene-editing tool. It could allow researchers to take fragments of DNA extracted from human cells, put them into a test tube, and quickly and precisely engineer multiple changes to the genetic code, according to a new study published today in the CRISPR Journal.

Investigators at the Gene Editing Institute, which is part of the Helen F. Graham Cancer Center & Research Institute at Christiana Care, said their new “cell-free” CRISPR technology is the first CRISPR tool capable of making multiple edits to DNA samples “in vitro,” which means in a test tube or petri dish. The advance could have immediate value as a diagnostic tool, replicating the exact genetic mutations found in the tumors of individual cancer patients. Mutations that cause cancer to spread can differ from patient to patient, and being able to quickly identify the correct mutation affecting an individual patient can allow clinicians to implement a more targeted treatment strategy.

“With this new advance, we should be able to work with laboratory cultures and accomplish gene edits in less than a day, significantly reducing the time required for diagnostics compared to other CRISPR tools, and with much greater precision,” said Eric Kmiec, Ph.D., director of the Gene Editing Institute and principal author of the study. “This is particularly important for diagnostics linked to cancer care where time is critical.”

Antioxidant found to wind back the clock on blood vessel function

Posted by in categories: biotech/medical, life extension

Much mystery surrounds the physiological processes by which humans age, but scientists are learning more all the time. With this knowledge come new possibilities around how we can not only slow them down, but possibly even reverse them. A new breakthrough at the University of Colorado is the latest advance in the area, demonstrating how a chemically altered nutritional supplement may well reverse aging of the blood vessels, in turn giving cardiovascular health a vital boost.

The human body is pretty good at fending off oxidative stress when we’re young, protecting molecules from critical damage caused by rogue molecules known as free radicals. These are molecules that have found themselves with at least one unpaired electron, so they set off in search of a match, often robbing another molecule of theirs and setting off a chain reaction of irreversible molecular damage.

Move Over, Double Helix: A New Form of DNA Has Just Been Discovered

Posted by in category: biotech/medical

We all know about the double helix structure of DNA, but researchers have described a type of DNA that’s never been observed in a living cell: i-motif DNA. This knot-shaped DNA uses nucleotides differently than helical DNA, and scientists suspect it plays a regulatory role in the cell.

Gain of toxic apolipoprotein E4 effects in human iPSC-derived neurons is ameliorated by a small-molecule structure corrector

Posted by in categories: biotech/medical, neuroscience

Today we will be discussing new research published in nature where researchers modified a protein associated with Alzheimer’s disease into a more harmless form, allowing them to remove the damage caused by Alzheimer’s in human cells. This is especially important because the research was not conducted on mice but rather human cells, and shows a potential way to halt the formation of the plaques associated with Alzheimer’s in the first place.

What Are Senolytics?

Posted by in categories: biotech/medical, life extension

Today, we have a guest article from Dr. Marion Tible, a scientist, and author over at the aging research-focused blog Long Long Life. What follows is an introduction to the senescent cell-clearing therapies known as senolytics, these therapies are poised to enter human trials and if successful could revolutionize how we treat age-related diseases.

What are senolytics?

Discovered in 2015 by a team from Mayo Clinic and the Scripps Research Institute in the United States, senolytics are a growing trend in the anti-aging community. They are very promising drugs in the fight against cellular senescence, a hallmark of aging.
