The Movie to Ensure Your Longevity

In a previous letter, I mentioned Ray Kurzweil would be one of the most influential persons as to when extreme life extension arrives. As a result, he could be responsible for helping rescue millions from premature suffering and death. Ray doesn™t do aging research. He is an inventor and a thinking machine. In fact, he is described as œthe ultimate thinking machine by Forbes and œthe restless genius by the Wall Street Journal.

Inc. magazine ranked him #8 among entrepreneurs in the United States, calling him the œrightful heir to Thomas Edison, and PBS included Ray as one of 16 œrevolutionaries who made America. Bill Gates called him the most accurate predictor of future of technologies.   

An independent, feature-length documentary was made about Kurzweil, his life, and his ideas called Transcendent Man. It recently premiered at the Tribeca Film Festival. Transcendent Man documents Ray's quest to reveal mankind's ultimate destiny and explores many of the ideas found in his New York Times bestselling book, The Singularity is Near. He movie includes his concept of exponential growth, radical life expansion, and how we will transcend our biology.

I have known and respected Ray for a number of years. The reason I say he is integral to developing extreme life extension in our lifetimes is his Law of Accelerating Returns. Ray and his ten person research team compiled thousands of pages of documents to predict the future of technology by carefully applying the concept of exponential growth. He has been uncanningly accurate in the past.

Essentially, the technology we use to solve challenges such as aging and disease doubles in power every year and will continue to double even quicker as time passes. That means the incredibly sophisticated tools we use today will be over 1000 times more powerful in only 10 years and a billion times more powerful in 25 years.

So isn™t that destined to happen anyway? Sure. But Ray brings awareness to the concept and teaches the world that age reversal is possible in your lifetimes. That in turn motivates people like me to write about it and to encourage investments and donations to launch the research and finish it while you are still alive. It encourages students to enter the field, and it lights fires under the whole industry.

Once Transcendent Man gets distributed, it will add even more fuel to the fire. Moving research up by just one year could rescue up to 37 million dying people.

I had the good fortune to attend a private viewing last Thursday evening. When you see Transcendent Man, you will then understand the implications it could have on your health and longevity.


THE CONTINUING SEARCH FOR HUMAN LONGEVITY GENES (August 28 2009) http://www.longevitymeme.org/news/vnl.cfm?id=4355
This study shows centenarians to more often carry a variant gene that affects exonuclease 1 (EXO1), involved in some forms of DNA repair - adding some fuel to the debate over the significance of nuclear DNA damage in aging. At this stage researchers are turning up longevity-associated differences in genes at a much faster rate than progress in understanding how it all ties together and how important specific genetic differences might be. From the paper: "Human longevity is heritable with a genetic component of 25-32%. Variation in genes regulating the levels of somatic maintenance and DNA repair functions is thought to modulate the aging process and to contribute to survival at advanced age. We tested 92 non-synonymous SNPs in 49 DNA repair genes for a possible association with longevity in a sample of 395 German centenarians and 411 controls. The obtained association signal in exonuclease 1 (EXO1) was further investigated by fine-mapping and mutation detection, leading to the identification of the functionally relevant SNP rs1776180. Our detailed analyses revealed that the common allele (C) of this promoter SNP is significantly enriched in female centenarians. This finding replicated in 455 female French centenarians and 109 controls. Given the survival advantage that is associated with the C allele of rs1776180, EXO1 can be considered a candidate for a novel longevity-enabling gene."

EXAMINING THE AGED IMMUNE SYSTEM IN SKIN (August 28 2009) http://www.longevitymeme.org/news/vnl.cfm?id=4354
Via ScienceDaily: "We wanted to uncover the workings of skin health in order to see why older people don't deal well with skin infections and are prone to skin cancers also.  In the past, the reduction in skin health was put down to potential defects in the white blood cells called T-cells that would usually help to identify and clear infection. However, when experiments were carried out with healthy young individuals under the age of 40 years and older individuals over the age of 70 years in this study, it was shown that in fact there is nothing wrong with the T-cells in the older group; instead it is the inability of their skin tissue to attract T-cells where and when they are needed that is the source of reduced immunity. ... Knowing this now raises the question of whether the same defect also occurs in other tissues during aging. Is it possible that, for example, lung tissues also fail to give out the right message to T-cells to bring them into the tissue to do their job? This may explain, in part, the higher rates of lung cancer, chest infections and pneumonia in older people, perhaps. At least in the test tube, it is possible to make older skin express the missing signals that attract T cells. This indicates that, in principle, the defect is entirely reversible."

LINKING INFLAMMATION AND INSULIN RESISTANCE (August 27 2009) http://www.longevitymeme.org/news/vnl.cfm?id=4353
Excess visceral fat, the insulin resistance of type 2 diabetes and metabolic syndrome, and chronic, damaging inflammation all go together. But why? Looking at the fat tissue tells us that macrophages seem to be involved, but here researchers dive in deeper, finding "in cultured cells and mouse experiments that Fox01 stimulates inflammatory white blood cells called macrophages, which migrate to the liver and adipose, or fat, tissue in insulin-resistant states, to increase production of a cytokine called interleukin-1 beta (IL-1B). The cytokine in turn interferes with insulin signaling. Insulin typically inhibits Fox01, setting up a feedback loop in healthy tissues that helps regulate insulin levels. The findings suggest that when there is a lack of insulin or when cells such as macrophages are resistant to its presence, there are no brakes on Fox01's stimulation of IL-1B and its further interference with insulin signaling. That might explain why chronic inflammation often is coupled with obesity and type 2 diabetes." All the more reason to take better care of your health so that you don't find yourself experiencing this firsthand.

THE SOCIAL JUSTICE VIEW OF LONGEVITY SCIENCE (August 27 2009) http://www.longevitymeme.org/news/vnl.cfm?id=4352
The interesting thing about longevity science is that the end result - a much longer, healthier life - is so compelling that even communities traditionally opposed to free and rapid development of new technologies on ideological grounds (such as prioritizing equality so highly that universal poverty and death is preferable to inequality) find their members coming around eventually. See this, for example, from an ethicist steeped in the social justice viewpoint: "A fair system of social cooperation is one that is both rational and reasonable (John Rawls, 2001). Is it rational and reasonable for societies that (1) are vulnerable to diverse risks of morbidity (e.g. cancer, heart disease) and mortality, and (2) are constrained by limited medical resources, to prioritize aging research? In this paper I make the case for answering 'yes' on both accounts. Focusing on a plausible example of an applied gerontological intervention (i.e. an anti-aging pharmaceutical), I argue that the goal of decelerating the rate of human aging would be a more effective strategy for extending the human healthspan than the current strategy of just tackling each specific disease of aging. Furthermore, the aspiration to retard human aging is also a reasonable aspiration, for the principle that underlies it (i.e. the duty to prevent harm) is one that no one could reasonably reject."

MORE REPROGRAMMING TO CREATE RETINAL CELLS (August 26 2009) http://www.longevitymeme.org/news/vnl.cfm?id=4350
Closely following reprogramming of bone marrow cells into retinal cells, researchers have now demonstrated that induced pluripotent stem cells (iPS cells) can turn out retinal cells as well: the scientists have "grown multiple types of retina cells from two types of stem cells - suggesting a future in which damaged retinas could be repaired by cells grown from the patient's own skin. Even sooner, the discovery will lead to laboratory models for studying genetically linked eye conditions, screening new drugs to treat those conditions and understanding the development of the human eye. This is an important step forward for us, as it not only confirms that multiple retinal cells can be derived from human iPS cells [but] also shows how similar the process is to normal human retinal development. That is quite remarkable given that the starting cell is so different from a retinal cell and the whole process takes place in a plastic dish. We continue to be amazed at how deep we can probe into these early events and find that they mimic those found in developing retinas. Perhaps this is the way to close the gap between what we know about building a retina in mice, frogs and flies with that of humans."

MISFOLDED PROTEINS INTERFERE WITH HEAT SHOCK RESPONSE (August 25 2009) http://www.longevitymeme.org/news/vnl.cfm?id=4349
Protein misfolding is a form of damage that accumulates with age. Here researchers show that some misfolds are more important than others: "Misfolded and damaged proteins spell trouble and are common to all human neurodegenerative diseases and many other age-associated diseases. But when during a lifespan do proteins start to misbehave? A new [study] reports that protein damage can be detected much earlier than we had thought, long before individuals exhibit symptoms. But the study also suggests if we intervene early enough, the damage could be delayed. In studying seven different proteins of the worm C. elegans, the researchers discovered that each protein misfolds at the same point: during early adulthood and long before the animal shows any behavioral, or physiological, change. The misfolding coincided with the loss of a critical protective cellular mechanism: the ability to activate the heat shock response, an ancient genetic switch that senses damaged proteins and protects cells by preventing protein misfolding." You might recall that enhanced heat shock response is how SIRT1 is thought to influence health and longevity, and there is a growing interest in manipulating the heat shock response as the basis for longevity and cancer therapies.

OBESITY, DEMETIA, AND SHRINKING BRAINS (August 25 2009) http://www.longevitymeme.org/news/vnl.cfm?id=4348
More on the link between obesity and increased risk of dementia from the New Scientist: "Brain regions key to cognition are smaller in older people who are obese compared with their leaner peers, making their brains look up to 16 years older than their true age. As brain shrinkage is linked to dementia, this adds weight to the suspicion that piling on the pounds may up a person's risk of the brain condition. Previous studies suggested that obesity in middle age increases the risk of dementia decades later, which is accompanied by increased brain shrinkage compared with leaner people. Now brain scans of older people have revealed the areas that are hardest hit, as well as the full extent of brain size differences between obese people and those of average weight. High insulin levels and type 2 diabetes tend to accompany being overweight and are risk factors for brain tissue loss and dementia. However, the relationship between brain size and body mass index still stood when the researchers accounted for these conditions, indicating that body fat levels may be linked directly to brain shrinkage. Thompson suggests that as increased body fat ups the chances of having clogged arteries, which can reduce blood and oxygen flow to brain cells."

BIOGERONTOLOGY RESEARCH FOUNDATION FUNDS WILT STUDY (August 24 2009) http://www.longevitymeme.org/news/vnl.cfm?id=4346

News from a UK research charity supportive of the Strategies for Engineered Negligible Senescence (SENS): "The Biogerontology Research Foundation in collaboration with the Institute for Biology of Aging funds research in hematopoietic stem cell transplantation in telomerase-knockout mice. Mammals must finely balance stimulation and suppression of cell division: over-permissive cellular proliferation promotes cancer, whereas over-restrictive cell division promotes degeneration. This is especially true in tissues with a high cell turnover, such as the blood. Genetic manipulation of the machinery that maintains the ends of our chromosomes, combined with cell therapy, is potentially a very powerful way to alleviate this problem. However, such an approach is highly complex; as a result, researchers have been reluctant to investigate its components. In this new project, the blood will be used as an example to demonstrate the feasibility of such a manipulation. This project will be the first ever test of whether intrinsically mortal stem cells can maintain a proliferating tissue indefinitely if periodically replenished. If the answer is yes, this will motivate exploring such treatments as part of an exceptionally robust cancer-prevention therapy." You will recognize this as an early test of WILT, the SENS strategy for eliminating cancer by destroying its most fundamental required mechanism.
