I had previously looked at making two large concrete or nanomaterial monolithic or geodesic domes over cities which could protect a city from nuclear bombs.

Now Alexander Bolonkin has come up with a cheaper, technological easy and more practical approach with thin film inflatable domes. It not only would provide protection form nuclear devices it could be used to place high communication devices, windmill power and a lot of other money generating uses. The film mass covered of 1 km**2 of ground area is M1 = 2×10**6 mc = 600 tons/km**2 and film cost is $60,000/km**2.
The area of big city diameter 20 km is 314 km**2. Area of semi-spherical dome is 628 km2. The cost of Dome cover is 62.8 millions $US. We can take less the overpressure (p = 0.001atm) and decrease the cover cost in 5 – 7 times. The total cost of installation is about 30–90 million $US. Not only is it only about $153 million to protect a city it is cheaper than a geosynchronous satellite for high speed communications. Alexander Bolonkin’s website

Dreamers of a Better Future, Unite!

Posted by in categories: biological, futurism, geopolitics, space

[Crossposted from the blog of Starship Reckless]

Views of space travel have grown increasingly pessimistic in the last decade. This is not surprising: SETI still has received no unambiguous requests for more Chuck Berry from its listening posts, NASA is busy re-inventing flywheels and citizens even of first-world countries feel beleaguered in a world that seems increasingly hostile to any but the extraordinarily privileged. Always a weathervane of the present, speculative fiction has been gazing more and more inwardly – either to a hazy gold-tinted past (fantasy, both literally and metaphorically) or to a smoggy rust-colored earthbound future (cyberpunk).

The philosophically inclined are slightly more optimistic. Transhumanists, the new utopians, extol the pleasures of a future when our bodies, particularly our brains/minds, will be optimized (or at least not mind that they’re not optimized) by a combination of bioengineering, neurocognitive manipulation, nanotech and AI. Most transhumanists, especially those with a socially progressive agenda, are as decisively earthbound as cyberpunk authors. They consider space exploration a misguided waste of resources, a potentially dangerous distraction from here-and-now problems – ecological collapse, inequality and poverty, incurable diseases among which transhumanists routinely count aging, not to mention variants of gray goo.

And yet, despite the uncoolness of space exploration, despite NASA’s disastrous holding pattern, there are those of us who still stubbornly dream of going to the stars. We are not starry-eyed romantics. We recognize that the problems associated with spacefaring are formidable (as examined briefly in Making Aliens 1, 2 and 3). But I, at least, think that improving circumstances on earth and exploring space are not mutually exclusive, either philosophically or – perhaps just as importantly – financially. In fact, I consider this a false dilemma. I believe that both sides have a much greater likelihood to implement their plans if they coordinate their efforts, for a very simple reason: the attributes required for successful space exploration are also primary goals of transhumanism.

The Global Viral Forecasting Initiative

Posted by in categories: biological, biotech/medical

The Economist has a piece on the Global Viral Forecasting Initiative (GVFI):

Dr [Nathan] Wolfe, [a virologist at the University of California, Los Angeles], is attempting to create what he calls the Global Viral Forecasting Initiative (GVFI). This is still a pilot project, with only half a dozen sites in Africa and Asia. But he hopes, if he can raise the $50m he needs, to build it into a planet-wide network that can forecast epidemics before they happen, and thus let people prepare their defences well in advance. […]

The next stage of the project is to try to gather as complete an inventory as possible of animal viruses, and Dr Wolfe has enlisted his hunters to take blood samples from whatever they catch. He is collaborating with Eric Delwart and Joe DeRisi of the University of California, San Francisco, to screen this blood for unknown viral genes that indicate new species. The GVFI will also look at people, monitoring symptoms of ill health of unknown cause and trying to match these with unusual viruses.

Using Lasers to Detect Diseases via Breath

Posted by in categories: biological, chemistry

Today, the University of Colorado at Boulder made an announcement regarding a very promising technology:

Known as optical frequency comb spectroscopy, the technique is powerful enough to sort through all the molecules in human breath and sensitive enough to distinguish rare molecules that may be biomarkers for specific diseases

Combined with other rapid-response technologies, this could be part of the detection side of a BioShield, a technological immune system for humanity.

The optical frequency comb is a very precise laser for measuring different colors, or frequencies, of light, said Ye. Each comb line, or “tooth,” is tuned to a distinct frequency of a particular molecule’s vibration or rotation, and the entire comb covers a broad spectral range — much like a rainbow of colors — that can identify thousands of different molecules.

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

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

Some Progress on Universal Influenza Vaccine

Posted by in categories: biological, biotech/medical

According to ScienceDaily:

The British-American biotech company Acambis reports the successful conclusion of Phase I trials of the universal flu vaccine in humans. The universal influenza vaccine has been pioneered by researchers from VIB and Ghent University. This vaccine is intended to provide protection against all ‘A’ strains of the virus that causes human influenza, including pandemic strains. Therefore, this vaccine will not need to be renewed annually.

InfluenzaWhat would make this new vaccine different from the ones already available is that it would target M2e, a conserved region of influenza “A” strains. Since that part doesn’t constantly mutate and about 2/3 of seasonal epidemics and all pandemics are due to type “A” strains, it could be a very efficient weapon against repeats of the “Spanish Flu” (1918−1919) that killed at least 50 million people worldwide. Only the future will tell if phase II and III trials are successful.

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.

Accelerating Greenland Melting “Shocks” Scientists

Posted by in categories: biological, sustainability

The New York Times is reporting today that the continued acceleration of the rate at which the Greenland ice sheets are melting has scientists scrambling for answers. In particular, a combination of changes has the glaciologists particularly concerned. They say the accumulation of meltwater on the surface of the ice in the form of ponds and streams absorbs as much as four times more heat than the lighter-colored ice, thereby accelerating the surface’s rate of melting.

Additionally, this meltwater eventually finds its way to bedrock, where it appears to slightly lubricate the surface between ice and rock, facilitating more rapid ice shifting towards the ocean. A third factor in the trifecta is the breakup of substantial semi-submerged clots of ice that typically block narrow fjords. As these blockages break up, the flow of the frozen glacial rivers accelerates.

While there is still a tremendous amount about this cycle that remains undiscovered, what is clear is that the best estimates to date have fallen far short in terms of the speed at which these rare environments are changing. Although questions remain about how much of these changes are cyclical and how much is due precisely to man-originated global warming, we must gain a more complete understanding of these events so that we can take whatever steps we must to ameliorate any damage we’ve caused before the situation becomes so critical that massive changes come about as a result of our negligent handling of our environment.
