Helphookup.com internet empowered volunteers against disasters

Posted by in categories: defense, existential risks, futurism, lifeboat, open access, open source, sustainability

The inspiration of Help Hookup is actually a comic book called Global Frequency by Warren Ellis. My brother, Alvin Wang, took the idea to startup weekend and they launched the idea this past weekend for hooking up volunteers. It is similar to the concepts of David Brin’s “empowered citizens” and Glenn Reynolds “an army of Davids”. The concepts are compatible with the ideas and causes of the Lifeboat foundation.

Global Frequency was a network of 1,001 people that handled the jobs that the governments did not have the will to handle. I thought that it was a great idea and it would be more powerful with 1,000,001 people or 100,000,001 people. We would have to leave out the killing that was in the comic.

Typhoons, earthquakes, and improperly funded education could all be handled. If there is a disaster, doctors could volunteer. Airlines could provide tickets. Corporations could provide supples. Trucking companies could provide transportation. Etc. State a need, meet the need. No overhead. No waste.

The main site is here it is a way for volunteers to hookup

The helphookup blog is tracking the progress.

Yellowstone Caldera Rising

Posted by in category: existential risks

The Yellowstone caldera has moved upwards nine inches over the last three years, a record rate since geologists first began taking measurements in the 1920s. This is the result of a Los Angeles-sized blob of magma that recently rose up into the chamber only six miles below the surface. The Yellowstone caldera is an ancient supervolcano. Last time it erupted, 642,000 years ago, it ejected 1,000 cubic kilometers of magma into the air. If this happened in today’s world, it would kill millions and cover most of the United States in a layer of ash at least a centimeter thick. The lighter ash would rise up into the atmosphere, initiating a volcanic winter and ruining crops worldwide.

Calderas rise and fall worldwide all the time without erupting. But the activity in Yellowstone is still concerning. Like a reckless teenager in a sports car, it seems as if our civilization laughs off the possibility of its own demise like a complete joke. Yet the right sort of event, and we could be knocked flat. Instead of waiting for a disaster to happen, we should prepare in advance to minimize its probability.

I would like to see scientists do a study on the feasibility of using nuclear weapons to initiate a supervolcano eruption. If it looks feasible, then park security in Yellowstone should be increased.

One shot Gene therapy protection from radiation

Posted by in categories: defense, existential risks, futurism, lifeboat, nuclear weapons

University of Pittsburgh researchers injected a therapy previously found to protect cells from radiation damage into the bone marrow of mice, then dosed them with some 950 roentgens of radiation — nearly twice the amount needed to kill a person in just five hours. Nine in 10 of the therapy-receiving mice survived, compared to 58 percent of the control group.

Between 30 and 330 days, there were no differences in survival rates between experiment and control group mice, indicating that systemic MnSOD-PL treatment was not harmful to survival.

The researchers will need to verify whether this treatment would work in humans.

This is part of the early development in the use of genetic modification to increase the biological defences (shields) of people against nuclear, biological and chemical threats. We may not be able to prevent all attacks, so we should improve our toughness and survivability. We should still try to stop the attacks and create the conditions for less attacks.

Structure of influenza B virus protein gives clues to next pandemic

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

Determining the structure of a protein called hemagglutinin on the surface of influenza B is giving researchers at Baylor College of Medicine and Rice University in Houston clues as to what kinds of mutations could spark the next flu pandemic.

This is interesting research and progress in understanding and possibly blocking changes that would lead to pandemics.

In a report that goes online today in the Proceedings of the National Academy of Sciences (PNAS), Drs. Qinghua Wang, assistant professor of biochemistry and molecular biology at BCM, and Jianpeng Ma, associate professor in the same department and their colleagues describe the actual structure of influenza B virus hemagglutinin and compare it to a similar protein on influenza A virus. That comparison may be key to understanding the changes that will have to occur before avian flu (which is a form of influenza A virus) mutates to a form that can easily infect humans, said Ma, who holds a joint appointment at Rice. He and Wang have identified a particular residue or portion of the protein that may play a role in how different types of hemagglutinin bind to human cells.

“What would it take for the bird flu to mutate and start killing people” That’s the next part of our work,” said Ma. Understanding that change may give scientists a handle on how to stymie it.

Inflatable Mirrors on spacecraft would move asteroids fastest

Posted by in categories: asteroid/comet impacts, defense, existential risks, lifeboat, space

New Scientist reports on a new study by researchers led by Massimiliano Vasile of the University of Glasgow in Scotland have compared nine of the many methods proposed to ward off such objects, including blasting them with nuclear explosions.

The team assessed the methods according to three performance criteria: the amount of change each method would make to the asteroid’s orbit, the amount of warning time needed and the mass of the spacecraft needed for the mission.

The method that came out on top was a swarm of mirror-carrying spacecraft. The spacecraft would be launched from Earth to hover near the asteroid and concentrate sunlight onto a point on the asteroid’s surface.

In this way, they would heat the asteroid’s surface to more than 2100° C, enough to start vaporising it. As the gases spewed from the asteroid, they would create a small thrust in the opposite direction, altering the asteroid’s orbit.

SCADA (in)Security’s Going to Cost Us

Posted by in categories: cybercrime/malcode, defense, existential risks

When I read about the “Aurora Generator Test” video that has been leaked to the media I wondered “why leak it now now and who benefits.” Like many of you, I question the reasons behind any leak from an “unnamed source” inside the US Federal government to the media. Hopefully we’ll all benefit from this particular leak.

Then I thought back to a conversation I had at a trade show booth I was working in several years ago. I was speaking with a fellow from the power generation industry. He indicated that he was very worried about the security ramifications of a hardware refresh of the SCADA systems that his utility was using to control its power generation equipment. The legacy UNIX-based SCADA systems were going to be replaced by Windows based systems. He was even more very worried that the “air gaps” that historically have been used to physically separate the SCADA control networks from power company’s regular data networks might be removed to cut costs.

Thankfully on July 19, 2007 the Federal Energy Regulatory Commission proposed to the North American Electric Reliability Corporation a set of new, and much overdue, cyber security standards that will, once adopted and enforced do a lot to help make an attacker’s job a lot harder. Thank God, the people who operate the most critically important part of our national infrastructure have noticed the obvious.

Hopefully a little sunlight will help accelerate the process of reducing the attack surface of North America’s power grid.

The Other Side of the Immortality Coin

Posted by in category: existential risks

There are two sides to living as long as possible: developing the technologies to cure aging, such as SENS, and preventing human extinction risk, which threatens everybody. Unfortunately, in the life extensionist community, and the world at large, the balance of attention and support is lopsided in favor of the first side of the coin, while largely ignoring the second. I see people meticulously obsessed with caloric restriction and SENS, but apparently unaware of human extinction risks. There’s the global warming movement, sure, but no efforts to address the bio, nano, and AI risks.

It’s easy to understand why. Life extension therapies are a positive and happy thing, whereas existential risk is a negative and discouraging thing. The affect heuristic causes us to shy away from negative affect, while only focusing on projects with positive affect: life extension. Egocentric biases help magnify the effect, because it’s easier to imagine oneself aging and dying than getting wiped out along with billions of others as a result of a planetary plague, for instance. Attributional biases work against both sides of the immortality coin: because there’s no visible bad guy to fight, people aren’t as juiced up as they would be, about, say, protesting a human being like Bush.

Another element working against the risk side of the coin is the assignment of credit: a research team may be the first to significantly extend human life, in which case, the team and all their supporters get bragging rights. Prevention of existential risks is a bit hazier, consisting of networks of safeguards which all contribute a little bit towards lowering the probability of disaster. Existential risk prevention isn’t likely to be the way it is in the movies, where the hero punches out the mad scientist right before he presses the red button that says “Planet Destroyer”, but because of a cooperative network of individuals working to increase safety in the diverse areas that risks could emerge from: biotech, nanotech, and AI.

Present-day immortalists and transhumanists simply don’t care enough about existential risk. Many of them are at the same stage with regards to ideological progression as most of humanity is against the specter of death: accepting, in denial, dismissive. There are few things less pleasant to contemplate than humanity destroying itself, but it must be done anyhow, because if we slip and fall, there’s no getting up.

Looking Human Extinction in the Face

Posted by in category: existential risks

A point on human extinction risk analysis.

To look at existential risk rationally requires that we maintain a cool, detached perspective. It’s somewhat hard to think of how this might be done, although watching videos of planetary destruction could actually help! As a detective needs to look at a few crime scenes before he can get experienced and move beyond being a simple gumshoe, existential risk analysts need to view simulations and thought experiments of planetary destruction before they can consider it without flinching. Because it is impossible to acquire experience of human extinction risk, as by definition no one is alive afterwards, we have to settle for simulations.

The reaction of many educated adults to extinction risk discussions reminds me of the reaction kids in my Middle School health classes had to the mention of the word “penis”: adolescent giggling. If I were to get onstage in front of a random audience and start talking about existential risk when they didn’t expect it, using words like “planetary destruction”, they’d probably start giggling, at least in their minds. Obviously, we have a way to mature as a society until we can look calmly at the prospect of our own demise. By resolving to do so yourself, you can be a part of the solution instead of the problem.

Last week a blogger for the Houston Chronicle, Eric Berger, covered my post on immortality and extinction risk, and the immaturity of most of the comments received is expected but also telling. One reader writes that we should hire Will Smith to save the world, another writes: “I don’t worry about this sort of thing, because when it happens, I’ll be dead and won’t care.” Just like how you get to see someone’s true self a little better when they’re a tad tipsy, we get to see what people really think of extinction risk analysis by their anonymous comments on a big website. When people are on the record, they aren’t likely to make pithy comments like those on the blog, but they might be thinking them, and what they say in public is likely to be a dressed-up version of these sentiments. For instance, there’s an article that appeared in The Mercury on the 22nd of April in 2003, “Disastronomer Royal: More Apocalyptic then the Pope”, which exemplifies the reaction to those who take the prospect of extinction risk seriously, referring to Martin Rees in this case. Extinction denialist articles are not hard to find on the Internet: just Google them.

NASA designs nuclear asteroid deflector

Posted by in categories: asteroid/comet impacts, existential risks, lifeboat, space

NASA’s Marshall Space Flight Center has designed a nuclear-warhead-carrying spacecraft, that would be boosted by the US agency’s proposed Ares V cargo launch vehicle, to deflect asteroids.

The Ares V launch vehicle is scheduled to first fly in 2018. It would launch 130 tons to LEO.

I welcome this study for providing a clearer analysis of the deflection options and the analyzing costs of searching for threatening asteroids.

The 8.9m (29ft)-long “Cradle” spacecraft would carry six 1,500kg (3,300lb) missile-like interceptor vehicles that would carry one 1.2MT B83 nuclear warhead each, with a total mass of 11,035kg.
