Dr. David Sinclair on aging and age reversal (compilation II on D. Sinclair by A. Grases)

Excerpts from Dr. David Sinclair appearances during 2019 and early 2020. The focus I highlight in this compilation is around the research in progress on aging, age-related diseases and biological age reversal.

Dr. Sinclair is a well-known geneticist, researcher and professor, first at MIT and since more than two decades ago, at Harvard University.

KLOTHO, new Intelligence Quotient boosting gene found

WASHINGTON: Scientists have found that people who have a variant of a longevity gene have improved brain skills such as thinking, learning and memory. Researchers found that increasing levels of the gene, called KLOTHO, in mice made them smarter, possibly by increasing the strength of connections between nerve cells in the brain.

“This could be a major step toward helping millions around the world who are suffering from Alzheimer’s disease and other dementias,” said Dena Dubal, an assistant professor of neurology, the David A Coulter Endowed Chair in Aging and Neurodegeneration at the University of California San Francisco (UCSF) and the lead author of the study published in Cell Reports. “If we could boost the brain’s ability to function, we may be able to counter dementias,” Dubal said.

People who have one copy of a variant, or form, of the KLOTHO gene, called KL-VS, tend to live longer and have lower chances of suffering a stroke whereas people who have two copies may live shorter lives and have a higher risk of stroke. In the study, researchers found that people who had one copy of the KL-VS variant performed better on a battery of cognitive tests than subjects who did not have it, regardless of age, sex or the presence of the apolipoprotein 4 gene, the main genetic risk factor for Alzheimer’s disease.

The ultra-rich are investing in companies trying to reverse aging. Is it going to work?

If you can’t defeat death, what if you could postpone it, or at least postpone the diseases commonly associated with getting old?

Many people, especially the ultra-wealthy in Silicon Valley, are investing money into companies trying to answer exactly those questions.

Amazon CEO Jeff Bezos and billionaire PayPal co-founder Peter Thiel have both invested in South San Francisco-based Unity Biotechnology, a company whose mission is to “extend human healthspan, the period in one’s life unburdened by the disease of aging.”

We are nearing ‘longevity escape velocity’ — where science can extend your life for more than a year for every year you are alive

“The possibility that 100 years old might become the new 60” : EXCELLENT SLOGAN that doesn’t resort to the troublesome” I word” (“Immortality”)! Good article to share with non-science friends: light on hard science, but good emotional impact, incl. that catchy slogan.


Technology hasn’t just improved our lives; it’s also extended them — considerably.

For most of history, humans lived about 25 years. Real acceleration emerged at the turn of the 20th century, when everything from the creation of antibiotics to the implementation of better sanitation to the increased availability of clean water, and the ability to tackle killers like cancer and heart disease has us living routinely into our 80s. But many scientists believe we’re not stopping there.

Technological convergence is fueling this conviction. The intersection of artificial intelligence, cloud computing, networks, sensors, robotics, massive datasets, biotechnology and nanotechnology is taking direct aim at the limits of human lifespan.

Are stem cells really the key to making humans live longer?

But apart from a few small-scale examples, the only stem cell-based medical treatment practised in clinics uses haematopoietic stem cells found in the blood and bone marrow – which only produce blood cells – for transplants in blood cancer patients. These cells are taken from a patient’s sibling or an unrelated donor, before being infused into a patient’s blood, or they’re taken from a patient’s own blood before being reinfused. The procedure has been used to treat blood malignancies for almost half a century, and recently multiple sclerosis too. So how likely is it that the predictions about stem cells’ longevity-enhancing powers will become a reality?


Startups are offering stem cells as the cure to everything from age-related illness to wrinkles. But the science is far from clear-cut.

Rejuvenate Bio launches to help dogs live longer, healthier lives

“Science hasn’t yet found a way to make complex animals like dogs live forever, so the next best thing we can do is find a way to maintain health for as long as possible during the aging process,” said Church.

And the goal was for this to hit a market and use the income to pay for human trials lasting 10 years.

Los Angeles: Healthy Aging

Ira Pastor, ideaXme exponential health ambassador, interviews Ms. Laura Trejo, General Manager of Los Angeles’s Department Of Aging.

Ira Pastor Comments:

The World Health Organization (WHO), through their Department of Ageing and Life Course, recently defined this new decade we have just entered (2020−2030) as “The Decade of Healthy Ageing” and see a major opportunity to bring together governments, civil society, international agencies, professionals, academia, the media, and the private sector for ten years of concerted, catalytic and collaborative action to improve the lives of older people, their families, and the communities in which they live.

As part of this initiative, they created the WHO Global Network for Age-friendly Cities and Communities, which represents a growing network of any city or community that is committed to creating inclusive and accessible urban environments to benefit their ageing populations.

A growing number of cities and communities worldwide are striving to better meet the needs of their older residents and the WHO Network was established to foster the exchange of experience and mutual learning between cities and communities worldwide.

Why SENS makes sense

In this post, you’ll find why I think SENS Research Foundation (SRF) is great to finance from an EA perspective along with the interview questions I want to ask its Chief Science Officer, Aubrey de Grey. You are welcome to contribute with your own questions in the comments or through a private message. Here is a brief summary of each section:

Introduction: Aging research looks extremely good as a cause-area from an EA perspective. Under a total utilitarian view, it is probably second or third after existential risk mitigation. There are many reasons why it makes sense to donate to many EA cause-areas, such as to reduce risk, if there are particularly effective specific interventions, or if some cause-areas are already well funded.

SRF’s approach to aging research: SRF selects its research following the SENS general strategy, which divides aging into seven categories of damage, each having a corresponding line of research. This categorization is very similar to the one described in the landmark paper The Hallmarks of Aging. This sort of damage repair approach seems more effective and tractable than current geriatrics and biogerontology that are aimed at slowing down aging, as it enables LEV and many more QALYs. It makes rejuvenation possible instead of just slowing down aging as a best-case scenario, and it doesn’t require an in-depth knowledge of our metabolism, which is extremely complicated and full of unknown-unknowns.
