Intimations of Imitations: Visions of Cellular Prosthesis & Functionally-Restorative Medicine

Posted by in categories: biological, biotech/medical, chemistry, engineering, futurism, life extension, nanotechnology, neuroscience

In this essay I argue that technologies and techniques used and developed in the fields of Synthetic Ion Channels and Ion Channel Reconstitution, which have emerged from the fields of supramolecular chemistry and bio-organic chemistry throughout the past 4 decades, can be applied towards the purpose of gradual cellular (and particularly neuronal) replacement to create a new interdisciplinary field that applies such techniques and technologies towards the goal of the indefinite functional restoration of cellular mechanisms and systems, as opposed to their current proposed use of aiding in the elucidation of cellular mechanisms and their underlying principles, and as biosensors.

In earlier essays (see here and here) I identified approaches to the synthesis of non-biological functional equivalents of neuronal components (i.e. ion-channels ion-pumps and membrane sections) and their sectional integration with the existing biological neuron — a sort of “physical” emulation if you will. It has only recently come to my attention that there is an existing field emerging from supramolecular and bio-organic chemistry centered around the design, synthesis, and incorporation/integration of both synthetic/artificial ion channels and artificial bilipid membranes (i.e. lipid bilayer). The potential uses for such channels commonly listed in the literature have nothing to do with life-extension however, and the field is to my knowledge yet to envision the use of replacing our existing neuronal components as they degrade (or before they are able to), rather seeing such uses as aiding in the elucidation of cellular operations and mechanisms and as biosensors. I argue here that the very technologies and techniques that constitute the field (Synthetic Ion-Channels & Ion-Channel/Membrane Reconstitution) can be used towards the purpose of the indefinite-longevity and life-extension through the iterative replacement of cellular constituents (particularly the components comprising our neurons – ion-channels, ion-pumps, sections of bi-lipid membrane, etc.) so as to negate the molecular degradation they would have otherwise eventually undergone.

While I envisioned an electro-mechanical-systems approach in my earlier essays, the field of Synthetic Ion-Channels from the start in the early 70’s applied a molecular approach to the problem of designing molecular systems that produce certain functions according to their chemical composition or structure. Note that this approach corresponds to (or can be categorized under) the passive-physicalist sub-approach of the physicalist-functionalist approach (the broad approach overlying all varieties of physically-embodied, “prosthetic” neuronal functional replication) identified in an earlier essay.

The field of synthetic ion channels is also referred to as ion-channel reconstitution, which designates “the solubilization of the membrane, the isolation of the channel protein from the other membrane constituents and the reintroduction of that protein into some form of artificial membrane system that facilitates the measurement of channel function,” and more broadly denotes “the [general] study of ion channel function and can be used to describe the incorporation of intact membrane vesicles, including the protein of interest, into artificial membrane systems that allow the properties of the channel to be investigated” [1]. The field has been active since the 1970s, with experimental successes in the incorporation of functioning synthetic ion channels into biological bilipid membranes and artificial membranes dissimilar in molecular composition and structure to biological analogues underlying supramolecular interactions, ion selectivity and permeability throughout the 1980’s, 1990’s and 2000’s. The relevant literature suggests that their proposed use has thus far been limited to the elucidation of ion-channel function and operation, the investigation of their functional and biophysical properties, and in lesser degree for the purpose of “in-vitro sensing devices to detect the presence of physiologically-active substances including antiseptics, antibiotics, neurotransmitters, and others” through the “… transduction of bioelectrical and biochemical events into measurable electrical signals” [2].

Stephen L. Coles is DYING and NEEDS your Help!

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

*** PLEASE alert your friends—Our own continued health and longevity may depend on Steve continuing his work.***

This call for support was also posted by Ilia Stambler on the Longevity Alliance Website, and organized on YouCaring.com by John M. Adams. Eric Schulke has also helped tremendously in spreading the word about the Fundraiser.

Since founding the Los Angeles Gerontology Research Group in 1990, Dr. L. Stephen Coles M.D., Ph.D., has worked tirelessly to develop new ways to slow and ultimately reverse human aging.

Everyone active in the LA-GRG or the Worldwide GRG Discussion Group have benefited from his expertise. His continual reporting of news about the latest developments to the List and his work in areas such as gathering blood samples for a complete genome analysis of the oldest people in the world (supercentenarians, aged 110+) is ground breaking and far ahead of anything that has ever been accomplished before. Publication of this work is expected in collaboration with Stanford University before the end of the year. Other accomplishments are equally notable

Lust for life: breaking the 120-year barrier in human ageing

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

By Avi Roy, University of Buckingham

In rich countries, more than 80% of the population today will survive past the age of 70. About 150 years ago, only 20% did. In all this while, though, only one person lived beyond the age of 120. This has led experts to believe that there may be a limit to how long humans can live.

Animals display an astounding variety of maximum lifespan ranging from mayflies and gastrotrichs, which live for 2 to 3 days, to giant tortoises and bowhead whales, which can live to 200 years. The record for the longest living animal belongs to the quahog clam, which can live for more than 400 years.

If we look beyond the animal kingdom, among plants the giant sequoia lives past 3000 years, and bristlecone pines reach 5000 years. The record for the longest living plant belongs to the Mediterranean tapeweed, which has been found in a flourishing colony estimated at 100,000 years old.

Longevity’s Bottleneck May Be Funding, But Funding’s Bottleneck is Advocacy & Activism

Posted by in categories: biological, biotech/medical, human trajectories, life extension, policy

The following article was originally published by Immortal Life

When asked what the biggest bottleneck for Radical or Indefinite Longevity is, most thinkers say funding. Some say the biggest bottleneck is breakthroughs and others say it’s our way of approaching the problem (i.e. that we’re seeking healthy life extension whereas we should be seeking more comprehensive methods of indefinite life-extension), but the majority seem to feel that what is really needed is adequate funding to plug away at developing and experimentally-verifying the various, sometimes mutually-exclusive technologies and methodologies that have already been proposed. I claim that Radical Longevity’s biggest bottleneck is not funding, but advocacy.

This is because the final objective of increased funding for Radical Longevity and Life Extension research can be more effectively and efficiently achieved through public advocacy for Radical Life Extension than it can by direct funding or direct research, per unit of time or effort. Research and development obviously still need to be done, but an increase in researchers needs an increase in funding, and an increase in funding needs an increase in the public perception of RLE’s feasibility and desirability.

There is no definitive timespan that it will take to achieve indefinitely-extended life. How long it takes to achieve Radical Longevity is determined by how hard we work at it and how much effort we put into it. More effort means that it will be achieved sooner. And by and large, an increase in effort can be best achieved by an increase in funding, and an increase in funding can be best achieved by an increase in public advocacy. You will likely accelerate the development of Indefinitely-Extended Life, per unit of time or effort, by advocating the desirability, ethicacy and technical feasibility of longer life than you will by doing direct research, or by working towards the objective of directly contributing funds to RLE projects and research initiatives.

If you want to live longer, do nothing

Posted by in categories: biotech/medical, life extension

By Avi Roy, University of Buckingham

I want to live longer and help others do the same. I assumed the most effective way to do that is by understanding the science of aging and then engineering solutions to extend human lifespan. That is why I became a biomedical researcher and over the past several years I have pursued this goal almost single-mindedly.

When a 2004 study showed that reducing the calorie intake in mice extended their life by 42%, I enthusiastically embraced the results and even put myself on a calorie restricted diet. But, subsequently, a 2012 study showed that long-term calorie restriction may not have the promised benefits. On the contrary, fewer calories without the required nutrients might actually cause harm.

Calorie restriction is not the first such “promising” route that eventually did not live up to the promise, and it will not be the last. Antioxidants showed promise in holding back diseases caused by aging, but now we know that antioxidant supplements are more likely to shorten your life.

The Life Extension Hubris: Why biotechnology is unlikely to be the answer to ageing

Posted by in categories: biological, biotech/medical, evolution, futurism, homo sapiens, life extension

It is often said that empiricism is one of the most useful concepts in epistemology. Empiricism emphasises the role of experience acquired through one’s own senses and perceptions, and is contrary to, say, idealism where concepts are not derived from experience, but based on ideals.

In the case of radical life extension, there is a tendency to an ‘idealistic trance’ where people blindly expect practical biotechnological developments to be available and applied to the public at large within a few years. More importantly, idealists expect these treatments or therapies to actually be effective and to have a direct and measurable effect upon radical life extension. Here, by ‘radical life extension’ I refer not to healthy longevity (a healthy life until the age of 100–120 years) but to an indefinite lifespan where the rate of age-related mortality is trivial.

Let me mention two empirical examples based on experience and facts:

1. When a technological development depends on technology alone, its progress is often dramatic and exponential.

An Open Letter to Death

Posted by in categories: biological, biotech/medical, homo sapiens, life extension, media & arts

lifebFreedom fironically found in flesh, not knowing whe’er I’m foul or fowl… tickly bound neath trickly form twisting and more unfresh as dawn upon dawn dies in menstrual skyfire like blood made light — a mocking microcosm of my own transubstantiation from rotting viscera to lightstorm infinity?

Just what sick joke is this? To wake and ache and dream and be and become! – and then to die..? To culminate the very universe itself!.. and then to simply die?! For what I ask you! What! Death… what audacious greed! What reckless squander and heedless extravagance!

Guttural red fringed black a bulbous muck death bastphelgmy! We cannot comprehend the sheer stature of death and so hurriedly cover the unknown with a word to hold it in hand and at a distance, to doubt no doubt.

O pallid heavens! O incessant sun undaunted by my barrenaked finitude! O fetid sanctity wet and redragged as the sickly bloom of jagged flesh! O putrid night sky serene despite my spat fury; as I ebb and ember a’roil withinside my sadness unbelieving and hysteric animal heat that vile sun and auster night jaunt their jeer and mock the rude squall of my panicstrewn death nonetheless.

Robots for Japan’s Future: talk with them, move with them, live with them… All in time.

Posted by in categories: biotech/medical, futurism, human trajectories, robotics/AI

NOT.GRANDMAS.ROBOT.NO.IS
Japanese People are Getting Old — Fast. So… Robots!

Japan is one of those great examples of how, when a society reaches a certain stage of development, population can stabilize itself based simply on quality of life (economic well-being, healthcare, community, Golden Rule morality, etc.). There is a challenge, however: population decline. In arguably one of the world’s most advanced capitalist nations, where 70% of GDP is based on the services economy and nearly all national debt is public held, a big die-off is… big problematic. Sure, the population decline will be gradual — but it’s inexorable, and Japan has to prepare now.

Make Robots, Not Babies?
A (perhaps questionable) study from the Japan Family Planning Association found that 1/3 of Japanese youth have no desire to get their groove on. They just don’t wanna hump each other. And as many of us know, it’s not just an enjoyable hobby, it’s where babies come from! Realistically, a decent number of respondents were probably lying, though. Because in Japan being fake polite and feigning ignorance to the nastiness & porno of human life is… a way of life (that’s a compliment — fake polite is far better than honest rude).

But actually, whether a large segment of the youth truly don’t want to make sweet love, or do, it doesn’t change the fact that Japan’s going to be running out of people. Factor in a rising women’s liberation, the destigmatization of birth control, and perceived economic instability — who knows what the actual equation looks like, but the answer is a birthrate of 1.39. And in case it’s not obvious, a birthrate of at least 2 is a replacement set for the parents; a population at stasis. Ain’t happening.

So, at the end of the day, replacing the lost population with robots, thereby replacing a lost labor force and augmenting the consumer economy — well, seems like a decent enough course of action.

Human Brain Mapping & Simulation Projects: America Wants Some, Too?

Posted by in categories: biological, biotech/medical, complex systems, ethics, existential risks, homo sapiens, neuroscience, philosophy, robotics/AI, singularity, supercomputing

YANKEE.BRAIN.MAP
The Brain Games Begin
Europe’s billion-Euro science-neuro Human Brain Project, mentioned here amongst machine morality last week, is basically already funded and well underway. Now the colonies over in the new world are getting hip, and they too have in the works a project to map/simulate/make their very own copy of the universe’s greatest known computational artifact: the gelatinous wad of convoluted electrical pudding in your skull.

The (speculated but not yet public) Brain Activity Map of America
About 300 different news sources are reporting that a Brain Activity Map project is outlined in the current administration’s to-be-presented budget, and will be detailed sometime in March. Hoards of journalists are calling it “Obama’s Brain Project,” which is stoopid, and probably only because some guy at the New Yorker did and they all decided that’s what they had to do, too. Or somesuch lameness. Or laziness? Deference? SEO?

For reasons both economic and nationalistic, America could definitely use an inspirational, large-scale scientific project right about now. Because seriously, aside from going full-Pavlov over the next iPhone, what do we really have to look forward to these days? Now, if some technotards or bible pounders monkeywrench the deal, the U.S. is going to continue that slide toward scientific… lesserness. So, hippies, religious nuts, and all you little sociopathic babies in politics: zip it. Perhaps, however, we should gently poke and prod the hard of thinking toward a marginally heightened Europhobia — that way they’ll support the project. And it’s worth it. Just, you know, for science.

Going Big. Not Huge, But Big. But Could be Massive.
Both the Euro and American flavors are no Manhattan Project-scale undertaking, in the sense of urgency and motivational factors, but more like the Human Genome Project. Still, with clear directives and similar funding levels (€1 billion Euros & $1–3 billion US bucks, respectively), they’re quite ambitious and potentially far more world changing than a big bomb. Like, seriously, man. Because brains build bombs. But hopefully an artificial brain would not. Spaceships would be nice, though.
