Mankind’s secrets kept in lunar ark

Posted by in categories: biotech/medical, defense, space

IF civilisation is wiped out on Earth, salvation may come from space. Plans are being drawn up for a “Doomsday ark” on the moon containing the essentials of life and civilisation, to be activated in the event of earth being devastated by a giant asteroid or nuclear war.

Construction of a lunar information bank, discussed at a conference in Strasbourg last month, would provide survivors on Earth with a remote-access toolkit to rebuild the human race.

A basic version of the ark would contain hard discs holding information such as DNA sequences and instructions for metal smelting or planting crops. It would be buried in a vault just under the lunar surface and transmitters would send the data to heavily protected receivers on earth. If no receivers survived, the ark would continue transmitting the information until new ones could be built.

Promising Anti-Radiation Drug Based on Carbon Nanotubes

Posted by in categories: defense, military, nanotechnology, nuclear weapons

The Defense Advanced Research Projects Agency (DARPA) gave a $540,000 grant to researchers from Rice University to do a fast-tracked 9-month study on a new anti-radiation drug based on carbon nanotubes:

“More than half of those who suffer acute radiation injury die within 30 days, not from the initial radioactive particles themselves but from the devastation they cause in the immune system, the gastrointestinal tract and other parts of the body,” said James Tour, Rice’s Chao Professor of Chemistry, director of Rice’s Carbon Nanotechnology Laboratory (CNL) and principal investigator on the grant. “Ideally, we’d like to develop a drug that can be administered within 12 hours of exposure and prevent deaths from what are currently fatal exposure doses of ionizing radiation.” […]

The new study was commissioned after preliminary tests found the drug was greater than 5,000 times more effective at reducing the effects of acute radiation injury than the most effective drugs currently available. […]

The drug is based on single-walled carbon nanotubes, hollow cylinders of pure carbon that are about as wide as a strand of DNA. To form NTH, Rice scientists coat nanotubes with two common food preservatives — the antioxidant compounds butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) — and derivatives of those compounds.

Cheap (tens of dollars) genetic lab on a chip systems could help with pandemic control

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

Cross posted from Next big future

Since a journal article was submitted to the Royal Society of Chemistry, the U of Alberta researchers have already made the processor and unit smaller and have brought the cost of building a portable unit for genetic testing down to about $100 Cdn. In addition, these systems are also portable and even faster (they take only minutes). Backhouse, Elliott and McMullin are now demonstrating prototypes of a USB key-like system that may ultimately be as inexpensive as standard USB memory keys that are in common use – only tens of dollars. It can help with pandemic control and detecting and control tainted water supplies.

This development fits in with my belief that there should be widespread inexpensive blood, biomarker and genetic tests to help catch disease early and to develop an understanding of biomarker changes to track disease and aging development. We can also create adaptive clinical trials to shorten the development and approval process for new medical procedures


The device is now much smaller than size of a shoe-box (USB stick size) with the optics and supporting electronics filling the space around the microchip

On the brink of Synthetic Life: DNA synthesis has increased twenty times to full bacteria size

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

Reposted from Next Big Future which was advancednano.

A 582,970 base pair sequence of DNA has been synthesized.

It’s the first time a genome the size of a bacterium has chemically been synthesized that’s about 20 times longer than [any DNA molecule] synthesized before.

This is a huge increase in capability. It has broad implications for DNA nanotechnology and synthetic biology.

Cell phone sensors detect radiation to thwart nuclear terrorism

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

PhysOrg.com is reporting that researchers at Purdue University are working to develop a system that would use a network of cell phones to track radiation in an effort to prevent terrorist attacks with dirty bombs or nuclear weapons. Tiny solid-state radiation sensors are already commercially available and the additional circuitry would not add significant bulk to portable electronic products.

The researchers tested the system and demonstrated that it is capable of detecting a weak radiation source 15 feet from the sensors. A fully developed system could cover a nation with millions of cell phones equipped with radiation sensors able to detect even light residues of radioactive material. Because cell phones already contain global positioning locators, the network of phones would serve as a large scale tracking system that would require no intervention from individual users.

Lifeboat Foundation SAB member asks “Is saving humanity is worth the cost?”

Posted by in categories: defense, futurism, geopolitics, lifeboat

In his most recent paper “Reducing the Risk of Human Extinction,” SAB member Jason G. Matheny approached the topic of human extinction from what is unfortunately a somewhat unusual angle. Jason examined the cost effectiveness of preventing humanity’s extinction due to a catastrophic asteroid impact.

Even with some rather pessimistic assumptions, his calculations showed a pretty convincing return on investment. For only about US$ 2.50 per life year saved, Matheny predicts that we could mitigate the risk of humanity being killed off by a large asteroid. Maybe it’s just me, but it sounds pretty compelling.

Matheny also made a very good point that we all should ponder when we consider how our charitable giving and taxes gets spent. “We take extraordinary measures to protect some endangered species from extinction. It might be reasonable to take extraordinary measures to protect humanity from the same.”

For more coverage on this important paper please see the October 2007 issue of Risk Analysis and a recent edition of Nature News.

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.

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.
