Undoing Aging with Molecular and Cellular Damage Repair

Since the dawn of medicine, aging has been doctors’ foremost challenge. Three unsuccessful approaches to conquering it have failed: treating components of age-related ill health as curable diseases, extrapolating from differences between species in the rate of aging, and emulating the life extension that famine elicits in short-lived species. SENS Research Foundation is spearheading the fourth age of anti-aging research: the repair of age-related damage, that is, rejuvenation biotechnology.

The Strategies for Engineered Negligible Senescence (SENS) approach was first proposed in 2002. “Senescence,” here, refers to the actuarial phenomenon—the trend that individuals within a population suffer from an increasing morbidity and mortality rate in (typically exponential) relation to their chronological age. “Negligible” is used in a statistical sense: we consider a level of senescence negligible if no age-related contribution to mortality is statistically demonstrable within a population, given the “background noise” of age-independent mortality (such as unfortunate encounters with motor vehicles). Finally, by “Engineered,” we indicate that this state is achieved by the deliberate application of biomedical therapies, and is not the normal situation. The goal of SENSE is thus unambiguously defined; we seek methods to convert a population experiencing a non-negligible level of senescence into one experiencing a negligible level.

Researchers Discover Key to Alzheimer’s Disease in Our Brains

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

Summary: Alzheimer’s and other neurodegenerative diseases are partially caused by the build-up of garbage due to a breakdown of the cellular housekeeping process known as autophagy. British scientists just discovered what may be the key to stopping this collapse in cellular housekeeping. [Author: Brady Hartman. This article first appeared on LongevityFacts.com. Follow us on Reddit | Google+ | Facebook. ]

Scientists at King’s College London (KCL) discovered new mechanisms of cell death in neurodegenerative disorders, which may be involved in the leading causes of dementia, such as Alzheimer’s and Parkinson’s disease. The novel research was published Wednesday in the journal Current Biology.

If the findings are expanded, the discovery could lead to new treatments for delaying the progression of previously incurable neurodegenerative conditions.

Company Offers to Freeze Your Body Before Death

Summary: Cryonics firm CryoGen makes a radical new proposal to freeze people before death, known as ‘mercy freezing.’ Customers will pay for the Cryopreservation: Also called cryobanking.

Cryonics is legally allowed only after death, and during this time the body starts to decay. Cryopreservation should ideally be performed within a few minutes of the patient’s demise. This happens less than half the time for current cryonics clients, and their tissues start turning to mush before freezing.

A Russian-Swiss company named CryoGen plans to solve that problem by freezing people before death, calling it ‘mercy freezing.’ CryoGen is building a cryonics lab in Switzerland, a country where euthanasia is legal. According to a white paper on CryoGen’s website.

This Anti-Aging Protein Could Be Targeted to Rejuvenate Our Immune Cells

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

Summary: Scientists discover that the anti-aging protein SIRT1 could be targeted to rejuvenate T cells in our aging immune systems. [Author: Brady Hartman] This article first appeared on LongevityFacts.com. Follow us on Reddit | Google+ | Facebook.

Anti-aging proteins in the sirtuin family have long been shown to protect against age-related diseases, such as cardiovascular disease, cancer, and neurodegeneration. A new research study by scientists at the Gladstone Institutes now reveals that the protein called SIRT1 could also be targeted to rejuvenate aging immune system cells. SIRT1 is commonly known for being activated by naturally occurring substances found in red wine.

In the new study, published Wednesday in the Journal of Experimental Medicine, the researchers found that SIRT1 is also involved in how immune system cells develop with age. The Gladstone scientists wanted to find out how the anti-aging protein SIRT1 affects the immune cells known as cytotoxic T cells. Also called killer T cells, these cells are highly specialized guardians of the immune system, and their role is to kill cancer cells, damaged cells, or those cells infected by a virus. More specifically, a cytotoxic T cell is a type of white blood cell and also a type of lymphocyte. To treat tumors, these can be separated from other blood cells, grown in a laboratory, and then given to a patient to kill cancer cells. Melanie Ott, a senior author of the new study, and a Gladstone Senior Investigator said.

Snake Oil and Continued Ill Health – Faustian Bargains

Posted by in category: life extension

We wanted to draw attention to an interesting paper that we saw today; this one argues that there are two broad Faustian bargains that people make while attempting to live longer. The first involves questionable products, and the second involves treating the symptoms of aging rather than the cause.

The First Faustian Bargain – Anti-aging

The first bargain is the promise made by the “anti-aging” industry, the supplement sellers who do not state outright but strongly imply that their elixirs could add years to your life. We have all seen the supplement blends with fancy names that often contain a mixture of compounds that we could obtain separately at far lower cost. These supplements are marketed as miracles, while their ingredients are only supported by mouse studies or sometimes not even that.

Older men need more protein to maintain muscles

Posted by in category: life extension

The amount of protein recommended by international guidelines is not sufficient to maintain muscle size and strength in older men, according to a new study.

Researchers say their findings mean should aim to have high quality at every meal.

The size of our skeletal muscles – the muscles we use to move our body – and our ability to perform everyday tasks naturally decline with age from the around the fifth decade. Severe loss can lead to frailty, loss of independence and a greater risk of dying.

Why Longer Lives Thanks to Science Will Probably Not Create Cultural Stagnation

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

You probably know the quote by Steve Jobs saying that death is life’s single best invention because it gets rid of the old and makes room for the new. This view is the core of another fairly common objection to rejuvenation, codename “cultural stagnation”.

Wouldn’t all those rejuvenated people, however physically young, be always old people “inside”, and drag everyone down with them into their anachronistic, surpassed ways of thinking, making it harder for fresh ideas to take hold, ultimately hindering social progress and our growth as a species? Maybe it’d be best not to take the risk, forget rejuvenation, and be content with old age as it is.

Well, try explaining to your grandfather that the reason he has to put up with heart disease is that we’re afraid people his age may all become troublemakers when you let them live too long.
