Gulches — freedom lifeboats

Posted by in categories: education, geopolitics, habitats, lifeboat, nuclear weapons

Jim Davies of Strike the Root writes about Galt’s Gulch and some gulch-like projects. These appeal to him because of the exponential trends in government power and abuse of power. He writes, in part,

“We have the serious opportunity in our hands right now of terminating the era of government absolutely, and so of removing from the human race the threat of ever more brutal tyranny ending only with WMD annihilation–while opening up vistas of peaceful prosperity and technological progress which even a realist like myself cannot find words to describe. ”

Avoiding those terrible events is what building our Lifeboat is all about. Got Lifeboat?

Microbe on Ice

Posted by in categories: biological, lifeboat

It sounds like cryonics is working, at least for microbes. But could any humans now alive have resistance to ancient organisms?

Rational Review carried a link to this story:

http://www.foxnews.com/story/0,2933,526460,00.html

“After more than 120,000 years trapped beneath a block of ice in Greenland, a tiny microbe has awoken. … The new bacteria species was found nearly 2 miles (3 km) beneath a Greenland glacier, where temperatures can dip well below freezing, pressure soars, and food and oxygen are scarce. ‘We don’t know what state they were in,’ said study team member Jean Brenchley of Pennsylvania State University. ‘They could’ve been dormant, or they could’ve been slowly metabolizing, but we don’t know for sure.’”

It is yet another interesting possibility against which humans should prepare to protect ourselves. Where is our Lifeboat?

What should be at the center of the U.S. stimulus package

Posted by in categories: existential risks, geopolitics, habitats, lifeboat, space, sustainability

The projected size of Barack Obama’s “stimulus package” is heading north, from hundreds of billions of dollars into the trillions. And the Obama program comes, of course, on top of the various Bush administration bailouts and commitments, estimated to run as high as $8.5 trillion.

Will this money be put to good use? That’s an important question for the new President, and an even more important question for America. The metric for all government spending ultimately comes down to a single query: What did you get for it?

If such spending was worth it, that’s great. If the country gets victory in war, or victory over economic catastrophe, well, obviously, it was worthwhile. The national interest should never be sacrificed on the altar of a balanced budget.

So let’s hope we get the most value possible for all that money–and all that red ink. Let’s hope we get a more prosperous nation and a cleaner earth. Let’s also hope we get a more secure population and a clear, strategic margin of safety for the United States. Yet how do we do all that?

Refuges and bunkers

Posted by in categories: asteroid/comet impacts, cybercrime/malcode, defense, existential risks, habitats, lifeboat, sustainability, treaties

Here I would like to suggest readers a quotation from my book “Structure of the global catastrophe” (http://www.scribd.com/doc/7529531/-) there I discuss problems of preventing catastrophes.

Refuges and bunkers

Different sort of a refuge and bunkers can increase chances of survival of the mankind in case of global catastrophe, however the situation with them is not simple. Separate independent refuges can exist for decades, but the more they are independent and long-time, the more efforts are necessary for their preparation in advance. Refuges should provide ability for the mankind to the further self-reproduction. Hence, they should contain not only enough of capable to reproduction people, but also a stock of technologies which will allow to survive and breed in territory which is planned to render habitable after an exit from the refuge. The more this territory will be polluted, the higher level of technologies is required for a reliable survival.
Very big bunker will appear capable to continue in itself development of technologies and after catastrophe. However in this case it will be vulnerable to the same risks, as all terrestrial civilisation — there can be internal terrorists, AI, nanorobots, leaks etc. If the bunker is not capable to continue itself development of technologies it, more likely, is doomed to degradation.
Further, the bunker can be or «civilizational», that is keep the majority of cultural and technological achievements of the civilisation, or “specific”, that is keep only human life. For “long” bunkers (which are prepared for long-term stay) the problem of formation and education of children and risks of degradation will rise. The bunker can or live for the account of the resources which have been saved up before catastrophe, or be engaged in own manufacture. In last case it will be simply underground civilisation on the infected planet.
The more a bunker is constructed on modern technologies and independent cultural and technically, the higher ammount of people should live there (but in the future it will be not so: the bunker on the basis of advanced nanotechnology can be even at all deserted, — only with the frozen human embryos). To provide simple reproduction by means of training to the basic human trades, thousand people are required. These people should be selected and be in the bunker before final catastrophe, and, it is desirable, on a constant basis. However it is improbable, that thousand intellectually and physically excellent people would want to sit in the bunker “just in case”. In this case they can be in the bunker in two or three changes and receive for it a salary. (Now in Russia begins experiment «Mars 500» in which 6 humans will be in completely independent — on water, to meal, air — for 500 days. Possibly, it is the best result which we now have. In the early nineties in the USA there was also a project «Biosphera-2» in which people should live two years on full self-maintenance under a dome in desert. The project has ended with partial failure as oxygen level in system began to fall because of unforeseen reproduction of microorganisms and insects.) As additional risk for bunkers it is necessary to note fact of psychology of the small groups closed in one premise widely known on the Antarctic expeditions — namely, the increase of animosities fraught with destructive actions, reducing survival rate.
The bunker can be either unique, or one of many. In the first case it is vulnerable to different catastrophes, and in the second is possible struggle between different bunkers for the resources which have remained outside. Or is possible war continuation if catastrophe has resulted from war.
The bunker, most likely, will be either underground, or in the sea, or in space. But the space bunker too can be underground of asteroids or the Moon. For the space bunker it will be more difficult to use the rests of resources on the Earth. The bunker can be completely isolated, or to allow “excursion” in the external hostile environment.
As model of the sea bunker can serve the nuclear submarine possessing high reserve, autonomy, manoeuvrability and stability to negative influences. Besides, it can easily be cooled at ocean (the problem of cooling of the underground closed bunkers is not simple), to extract from it water, oxygen and even food. Besides, already there are ready boats and technical decisions. The boat is capable to sustain shock and radiating influence. However the resource of independent swimming of modern submarines makes at the best 1 year, and in them there is no place for storage of stocks.
Modern space station ISS could support independently life of several humans within approximately year though there are problems of independent landing and adaptation. Not clearly, whether the certain dangerous agent, capable to get into all cracks on the Earth could dissipate for so short term.
There is a difference between gaso — and bio — refuges which can be on a surface, but are divided into many sections for maintenance of a mode of quarantine, and refuges which are intended as a shelter from in the slightest degree intelligent opponent (including other people who did not manage to get a place in a refuge). In case of biodanger island with rigid quarantine can be a refuge if illness is not transferred by air.
A bunker can possess different vulnerabilities. For example, in case of biological threat, is enough insignificant penetration to destroy it. Only hi-tech bunker can be the completely independent. Energy and oxygen are necessary to the bunker. The system on a nuclear reactor can give energy, but modern machines hardly can possess durability more than 30–50 years. The bunker cannot be universal — it should assume protection against the certain kinds of threats known in advance — radiating, biological etc.
The more reinforced is a bunker, the smaller number of bunkers can prepare mankind in advance, and it will be more difficult to hide such bunker. If after a certain catastrophe there was a limited number of the bunkers which site is known, the secondary nuclear war can terminate mankind through countable number of strikes in known places.
The larger is the bunker, the less amount of such bunkers is possible to construct. However any bunker is vulnerable to accidental destruction or contamination. Therefore the limited number of bunkers with certain probability of contamination unequivocally defines the maximum survival time of mankind. If bunkers are connected among themselves by trade and other material distribution, contamination between them is more probable. If bunkers are not connected, they will degrade faster. The more powerfully and more expensively is the bunker, the more difficult is to create it imperceptibly for the probable opponent and so it easeir becomes the goal for an attack. The more cheaply the bunker, the less it is durable.
Casual shelters — the people who have escaped in the underground, mines, submarines — are possible. They will suffer from absence of the central power and struggle for resources. The people, in case of exhaustion of resources in one bunker, can undertake the armed attempts to break in other next bunker. Also the people who have escaped casually (or under the threat of the comong catastrophe), can attack those who was locked in the bunker.
Bunkers will suffer from necessity of an exchange of heat, energy, water and air with an external world. The more independent is the bunker, the less time it can exist in full isolation. Bunkers being in the Earth will deeply suffer from an overheating. Any nuclear reactors and other complex machines will demand external cooling. Cooling by external water will unmask them, and it is impossible to have energy sources lost-free in the form of heat, while on depth of earth there are always high temperatures. Temperature growth, in process of deepening in the Earth, limits depth of possible bunkers. (The geothermal gradient on the average makes 30 degrees C/kilometers. It means, that bunkers on depth more than 1 kilometre are impossible — or demand huge cooling installations on a surface, as gold mines in the republic of South Africa. There can be deeper bunkers in ices of Antarctica.)
The more durable, more universal and more effective, should be a bunker, the earlier it is necessary to start to build it. But in this case it is difficult to foresee the future risks. For example, in 1930th years in Russia was constructed many anti-gase bombproof shelters which have appeared useless and vulnerable to bombardments by heavy demolition bombs.
Efficiency of the bunker which can create the civilisation, corresponds to a technological level of development of this civilisation. But it means that it possesses and corresponding means of destruction. So, especially powerful bunker is necessary. The more independently and more absolutely is the bunker (for example, equipped with AI, nanorobots and biotechnologies), the easier it can do without, eventually, people, having given rise to purely computer civilisation.
People from different bunkers will compete for that who first leaves on a surface and who, accordingly, will own it — therefore will develop the temptation for them to go out to still infected sites of the Earth.
There are possible automatic robotic bunkers: in them the frozen human embryos are stored in a certain artificial uterus and through hundreds or thousand years start to be grown up. (Technology of cryonics of embryos already exists, and works on an artificial uterus are forbidden for bioethics reasons, but basically such device is possible.) With embryos it is possible to send such installations in travel to other planets. However, if such bunkers are possible, the Earth hardly remains empty — most likely it will be populated with robots. Besides, if the human cub who has been brought up by wolves, considers itself as a wolf as whom human who has been brought up by robots will consider itself?
So, the idea about a survival in bunkers contains many reefs which reduce its utility and probability of success. It is necessary to build long-term bunkers for many years, but they can become outdated for this time as the situation will change and it is not known to what to prepare. Probably, that there is a number of powerful bunkers which have been constructed in days of cold war. A limit of modern technical possibilities the bunker of an order of a 30-year-old autonomy, however it would take long time for building — decade, and it will demand billions dollars of investments.
Independently there are information bunkers, which are intended to inform to the possible escaped descendants about our knowledge, technologies and achievements. For example, in Norway, on Spitsbergen have been created a stock of samples of seeds and grain with these purposes (Doomsday Vault). Variants with preservation of a genetic variety of people by means of the frozen sperm are possible. Digital carriers steady against long storage, for example, compact discs on which the text which can be read through a magnifier is etched are discussed and implemented by Long Now Foundation. This knowledge can be crucial for not repeating our errors.

Open Source Health Research Plan

Posted by in categories: biological, biotech/medical, lifeboat, open access, open source

Open source has emerged as a powerful set of principles for solving complex problems in fields as diverse as education and physical security. With roughly 60 million Americans suffering from a chronic health condition, traditional research progressing slowly, and personalized medicine on the horizon, the time is right to apply open source to health research. Advances in technology enabling cheap, massive data collection combined with the emerging phenomena of self quantification and crowdsourcing make this plan feasible today. We can all work together to cure disease, and here’s how.

SRA Proposal Accepted

Posted by in categories: existential risks, lifeboat

My proposal for the Society for Risk Analysis’s annual meeting in Boston has been accepted, in oral presentation format, for the afternoon of Wednesday, December 10th, 2008. Any Lifeboat members who will be in the area at the time are more than welcome to attend. Any suggestions for content would also be greatly appreciated; speaking time is limited to 15 minutes, with 5 minutes for questions. The abstract for the paper is as follows:

Global Risk: A Quantitative Analysis

The scope and possible impact of global, long-term risks presents a unique challenge to humankind. The analysis and mitigation of such risks is extremely important, as such risks have the potential to affect billions of people worldwide; however, little systematic analysis has been done to determine the best strategies for overall mitigation. Direct, case-by-case analysis can be combined with standard probability theory, particularly Laplace’s rule of succession, to calculate the probability of any given risk, the scope of the risk, and the effectiveness of potential mitigation efforts. This methodology can be applied both to well-known risks, such as global warming, nuclear war, and bio-terrorism, and lesser-known or unknown risks. Although well-known risks are shown to be a significant threat, analysis strongly suggests that avoiding the risks of technologies which have not yet been developed may pose an even greater challenge. Eventually, some type of further quantitative analysis will be necessary for effective apportionment of government resources, as traditional indicators of risk level- such as press coverage and human intuition- can be shown to be inaccurate, often by many orders of magnitude.

More details are available online at the Society for Risk Analysis’s website. James Blodgett will be presenting on the precautionary principle two days earlier (Monday, Dec. 8th).

30 days to make antibodies to limit Pandemics

Posted by in categories: biological, biotech/medical, defense, existential risks, lifeboat

Researchers have devised a rapid and efficient method for generating protein sentinels of the immune system, called monoclonal antibodies, which mark and neutralize foreign invaders.

For both ethical and practical reasons, monoclonals are usually made in mice. And that’s a problem, because the human immune system recognizes the mouse proteins as foreign and sometimes attacks them instead. The result can be an allergic reaction, and sometimes even death.

To get around that problem, researchers now “humanize” the antibodies, replacing some or all of mouse-derived pieces with human ones.

Wilson and Ahmed were interested in the immune response to vaccination. Conventional wisdom held that the B-cell response would be dominated by “memory” B cells. But as the study authors monitored individuals vaccinated against influenza, they found that a different population of B cells peaked about one week after vaccination, and then disappeared, before the memory cells kicked in. This population of cells, called antibody-secreting plasma cells (ASCs), is highly enriched for cells that target the vaccine, with vaccine-specific cells accounting for nearly 70 percent of all ASCs.

Preventing flu fatalities by stopping immune system overreaction

Posted by in categories: biological, defense, existential risks, futurism, lifeboat

Researchers from Imperial College in London, England, isolated the receptor in the lungs that triggers the immune overreaction to flu.

With the receptor identified, a therapy can be developed that will bind to the receptor, preventing the deadly immune response. Also, by targeting a receptor in humans rather than a particular strain of flu, therapies developed to exploit this discovery would work regardless of the rapid mutations that beguile flu vaccine producers every year.

The flu kills 250,000 to 500,000 people in an average year with epidemics reaching 1 to 2 million deaths (other than the spanish flu which was more severe

This discovery could lead to treatments which turn off the inflammation in the lungs caused by influenza and other infections, according to a study published today in the journal Nature Immunology. The virus is often cleared from the body by the time symptoms appear and yet symptoms can last for many days, because the immune system continues to fight the damaged lung. The immune system is essential for clearing the virus, but it can damage the body when it overreacts if it is not quickly contained.
