Meat grown in labs is the next logical step for food production

Posted by in categories: biotech/medical, futurism, sustainability

By Avi Roy, University of Buckingham

In his essay “Fifty Years Hence”, Winston Churchill speculated, “We shall escape the absurdity of growing a whole chicken in order to eat the breast or wing, by growing these parts separately under a suitable medium.”

At an event in London today, the first hamburger made entirely from meat grown through cell culture will be cooked and consumed before a live audience. In June at the TED Global conference in Edinburgh, Andras Forgacs took a step even beyond Churchill’s hopes. He unveiled the world’s first leather made from cells grown in the lab.

These are historic events. Ones that will change the discussion about lab-grown meat from blue-skies science to a potential consumer product which may soon be found on supermarket shelves and retail stores. And while some may perceive this development as a drastic shake-up in the world of agriculture, it really is part of the trajectory that agricultural technology is already following.

There is no war other than the one we are fighting with ourselves

Posted by in categories: economics, education, human trajectories, open source, sustainability

Just five years ago, anybody who spoke of technological unemployment was labeled a luddite, a techno-utopian, or just simply someone who doesn’t understand economics. Today things are very different – anybody from New York Times columnist Tom Friedman to CBS are jumping on the bandwagon.

Robots-Will-Steal-Your-Job-front

Those of us who have been speaking about the tremendous impact of automation in the workforce know very well that this isn’t a fad about to pass, but that it’s a problem that will only exacerbate in the future. Most of us agree on what the problem is (exponential growth of high-tech replacing humans faster and faster), and we agree that education will play a crucial role (and not coincidentally I started a companyEsplori – precisely to address this problem); but very few seem to suggest that we should use this opportunity to re-think our entire economic system and what the purpose of society should be. I am convinced this is exactly what we need to do. Published in 2012, my book, Robots Will Steal Your Job, But That’s OK: How to Survive the Economic Collapse and Be Happy – which you can also read online for free shows we might go about building a better tomorrow.

We have come to believe that we are dependent on governments and corporations for everything, and now that technology is ever more pervasive, our dependence on them is even stronger. And of course we don’t question the cycle of labor-for-income, income-for-survival and the conspicuous consumption model that has become dominant in virtually every country – and that not only is ecologically unsustainable, but it also generates immense income inequality.

Well, I do. I challenge the assumption that we should live to work, and even that we should work to live, for that matter. In an age where we already produce more than enough food, energy, and drinkable water for 7 billion people with little to no human labour, while 780 million lack access to clean water and 860 million are suffering from chronic hunger, it follows that the system we have in place isn’t allocating resources efficiently. And rather than going back to outdated ideologies (i.e. socialism), we can try new forms of societal structure; starting with open source philosophy, shared knowledge, self-reliance, and sustainable communities.

There are many transitional steps that we can take – reduced workweek, reform patent and copyright laws, switch to distributed and renewable energies – and there will be bumps along the road, no doubt. But if we move in the right direction, if we are ready to abandon ideologies and stick to whatever works best, I think we will prevail – simply because we will realise that there is no war other than the one we are fighting with ourselves.

The Power of the Move Outbound

There is a real power in the act of physically moving. In so doing, each and every morning I can escape the cacophonous curse of the ubiquitous ESPN in the gym locker room. I toss my bag in my locker and immediately escape to the pure, perfect, custom designed peace of my iPod’s audio world. I also well remember the glorious day I moved away from the hopelessness of my roommate’s awful sub-human, sub-slum stench and into my own private apartment. The universe changed miraculously overnight. I think you can get my drift. The simple act of moving itself can be powerfully transformational. Sometimes, there is not enough bleach and not enough distance between the walls to have the desired effect. Physically moving is quite often the only answer.

As we consider transhumanist societies, such transitional power is certainly the result by many magnitudes. My team has been engaged in developing the first permanent human undersea settlement over the past few decades. In this process we have had the distinct advantage of planning profoundly transhumanist advances specifically because of the advantageous context of relative community isolation. Further we have the benefit of deriving change as a community necessity — as a psychological and cultural imperative for this degree of advanced cultural evolution. It is a real kind of powerfully driven societal punctuated equilibrium that can be realized in few other ways.

In moving into the oceans, the submarine environment itself immediately establishes the boundary between the new, evolving culture and the old. While the effect and actual meaning of this boundary is almost always overrated, it is nonetheless a real boundary layer that allows the new culture to flourish sans the interferences or contamination from the old. Trying to accomplish transhumanist goals while culturally embedded is far more difficult and far less persuasive to those who must undergo dramatic change and for the transformation to actually take hold and survive generationally. But in a new, rather isolated environment, the pressure to evolve and integrate permanent change is not only easier, it is rather expected as a part of the reasonable process of establishment.

Who Wants To Live Forever?

Posted by in categories: business, ethics, existential risks, futurism, homo sapiens, human trajectories, life extension, philosophy, sustainability

Medical science has changed humanity. It changed what it means to be human, what it means to live a human life. So many of us reading this (and at least one person writing it) owe their lives to medical advances, without which we would have died.

Live expectancy is now well over double what it was for the Medieval Briton, and knocking hard on triple’s door.

What for the future? Extreme life extension is no more inherently ridiculous than human flight or the ability to speak to a person on the other side of the world. Science isn’t magic – and ageing has proven to be a very knotty problem – but science has overcome knotty problems before.

A genuine way to eliminate or severely curtail the influence of ageing on the human body is not in any sense inherently ridiculous. It is, in practice, extremely difficult, but difficult has a tendency to fall before the march of progress. So let us consider what implications a true and seismic advance in this area would have on the nature of human life.

Life and Boats

Posted by in categories: lifeboat, sustainability

In an enormously influential article published in 1974 in Psychology Today, and in a longer version published later that year in BioScience, Garrett Hardin introduced the metaphor of the lifeboat for economic and ethical consideration. This conceptual construction was intended as an improvement over the then-popular ecological metaphor of “spaceship earth” coined by Kenneth Boulding in 1966. Interestingly, in the opening paragraph of “Living on a lifeboat”, Hardin indicates that metaphors in general may be understood as only an early stage in mentally approaching difficult problems, and that this stage may be surpassed as theory advances and becomes more rigorous.

In Hardin’s analogy, large entities such as nations or the biosphere are likened to a boat, while smaller entities – for example, migrating individuals or groups – are likened to swimmers trying to board the already cramped vessel and exploit whatever resources are on board. In the imagined scenario, it is believed that the boat is near carrying capacity, but exactly how near is not known with certainty given the many future possibilities. A central question focuses on at what point, if any, the risk of sinking the entire boat outweighs the good provided for each additional rescued swimmer.

The metaphor of the lifeboat has structured thought about conservation, economics, ethics, and any number of other disciplinary areas for decades. The question I would like to pose is the following: Is the lifeboat scenario still (or was it ever) an apt metaphor for structuring thought about ethical conservation of resources, or have we reached a stage where the boat should be scuttled in favor of either a new metaphor or more literal language? Please feel free to post any thoughts you may have on this issue.

1. Thou shalt first guard the Earth and preserve humanity.

Impact deflection and survival colonies hold the moral high ground above all other calls on public funds.

2. Thou shalt go into space with heavy lift rockets with hydrogen upper stages and not go extinct.

Cosmic Ray Gorilla

Excerpt: “Galactic cosmic radiation poses a significant threat to future astronauts,” said M. Kerry O’Banion, M.D., Ph.D., a professor in the University of Rochester Medical Center (URMC) Department of Neurobiology and Anatomy and the senior author of the study. “The possibility that radiation exposure in space may give rise to health problems such as cancer has long been recognized. However, this study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease.”

It appears when Eugene Parker wrote “Shielding Space Travelers” in 2006 he was right- and all the private space sycophants claiming radiation mitigation is trivial are wrong.

Only a massive water shield a minimum of 14 feet thick and massing 400 tons for a small capsule can shield human beings in deep space on long duration missions. And since a small capsule will not have sufficient space to keep a crew psychologically healthy on a multi-year journey it is likely such a shield will massive over a thousand tons.

13: The Year of The Comet

Posted by in categories: asteroid/comet impacts, counterterrorism, defense, economics, ethics, events, existential risks, futurism, geopolitics, habitats, human trajectories, lifeboat, military, philosophy, policy, space, sustainability, transparency

A happy new year to the human race from it’s most important member; me. Since self-worship seems to be the theme of the new American ideal I had better get right with me.

With my government going over the fiscal cliff it would appear that the damned soul of Ayn Rand is exerting demonic influence on the political system through worship of the individual. The tea party has the Republicans terrified of losing their jobs. Being just like me, those individuals consider themselves the most important person on the planet- so I cannot fault them.

As Ayn Rand believed, “I will not die, it’s the world that will end”, so who cares about the collective future of the human race? Towards the end of 2013 the heavens may remind us the universe does not really care about creatures who believe themselves all important. The choice may soon be seen clearly in the light of the comet’s tail; the glorification of the individual and the certain extinction of our race, or the acceptance of a collective goal and our continued existence.

Ayn Rand made her choice but most of us have time to choose more wisely. I pray for billions, tens and hundreds of billions of dollars- for a Moonbase.

Beamed Energy Myth

Posted by in category: sustainability

I was recently told by a person commenting on another blog that beamed energy is a myth. The commenter claimed that Fusion energy would be a more likely future development. I cited Criswell and Zehner and gave back.I am a very progressive eco friendly person and I have wondered many years if there is some energy industry conspiracy that keeps clean power from becoming a reality. The only conspiracy is human greed influencing exactly how we live on this planet.

Zehner’s book spells out the situation in a unique way; he calls it as he see’s it and the numbers cannot be spun too much because he presents the basic foundations of what it takes to make the electricity flow. Criswell is more biased toward his proposal even though it is peer reviewed and has all the math equations.

What Criswell is proposing is a river of energy traveling from vast collectors on the surface of the Moon to Earth Geostationary orbit and from there down to surface recievers of several square kilometers.

What fusion proposes is to keep a sustained nuclear reaction going without the use of a sun. The other way to generate useful energy from a fusion reaction is to actually explode H-bombs underground and harvest the resulting heat and nuclear products. The only useful work that can be had from a H-bomb besides this kind of excavation is to use it as a propulsion device for spaceships.

Deathstars and David Criswell

Posted by in categories: space, sustainability

http://news.yahoo.com/blogs/ticket/build-death-star-petition…itics.html

When the possible mixes with fantasy it should turn peoples heads- it does not happen very often. But this toungue-in-cheek petition is actually a case of truth being so close to fiction and no one seems to be noticing. I have been posting in the comments section of Centauri Dreams lately due to my disappointment with the contributor situation on the lifeboat blog and I am now happy to share edited versions of them here.

It is now the second decade of the twenty first century and we actually have a
tremendous amount of technology available and devices that may have been tested in some form in the past and found to work quite well but by various circumstance did not enter production. The example that every real space nut is aware of is the Aerojet AJ-260 monolithic solid rocket booster. Each of these put out over 7 million pounds of thrust and would probably have been used in a pair with yet another aerojet product called the M-1 http://en.wikipedia.org/wiki/M-1_(rocket_engine) as a core liquid engine as in the Titan configuration. This was the logical progression of a more powerful partially reusable vehicle to replace the Saturn V; a vehicle with over twice the first stage thrust. Instead we tried to go cheap with the Space Shuttle and recieved zero ROI. In fact we have the ability to build much larger solid boosters of up to 325 inches. Built with submarine hull technology it is recovered at sea and resused. This system is the only practical reusable technology as the liquid shuttle motors turned out to be a total waste of time returning to earth for reuse.
