New Process Would Turn Greenhouse Gasses into Renewable Fuel Source

Posted by in categories: biotech/medical, chemistry


The New York Times reports
that Jeffrey Martin and William L. Kubic Jr., two scientists from Los Alamos National Laboratories are proposing a process by which the carbon dioxide — the primary greenhouse gas considered responsible for contributing to global warming — emitted from cars and other polluters would be captured and converted to gasoline, methane and jet fuel.

The bold proposal, which the duo have named “Green Freedom” would create a closed cycle from the emission of greenhouse gasses resulting in the creation of a vast source of renewable energy where today we have an open ended cycle that is considered a global threat.

They say the science is relatively simple and straight forward. Polluted air would be blown over potassium carbonate which would sequester the CO2, a chemical process would then remove the trapped CO2 and via a number of established chemical processes it would then be converted to various types of fuel.

Although the process has not been demonstrated and no prototypes have been built the pair claims that the required steps or other chemical processes that they say are close cousins to those required are already in use. In addition, none of the processes violate any known laws of physics and a number of other top researchers have independently made similar suggestions for the sequestration and reuse of emitted CO2.

This concept is not without its share of controversy and detractors however. With claims of everything from the fact that the economics of the process make it unfeasible to concerns that it will encourage further over–population and sprawl not to mention the worry that proliferation of nuclear power brings with it, it is nevertheless an interesting concept and proves — if nothing else — that through continued investment in breakthrough technologies we can overcome all challenges be they environmental or societal.

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.

ETC Group: Action Group on Erosion, Technology and Concentration

Posted by in category: biotech/medical

I’ve been taking a look at an “international civil society organization” called the ETC Group. The “ETC” group is also known as the “Action Group on Erosion, Technology and Concentration”. To be honest, I can’t figure them out. Here is a summary:

“ETC Group is an international civil society organization based in Canada. We are dedicated to the conservation and sustainable advancement of cultural and ecological diversity and human rights. ETC Group supports socially responsible development of technologies useful to the poor and marginalized and we address international governance issues affecting the international community. We also monitor the ownership and control of technologies and the consolidation of corporate power.”

So they look like a somewhat standard leftist environmentalist technology oversight group. Alright.

Lifeboat Foundation Fellow wins Feynman Prize

Posted by in categories: biotech/medical, lifeboat, nanotechnology

Robert Freitas, Jr., Lifeboat Foundation Fellow and head of the Lifeboat Foundation’s Nanomedicine Division has won the 2007 Foresight Institute Feynman Prize in Communication.

Dr. Pearl Chin, President of the Foresight Nanotech Institute, said Freitas received the award for “pioneering the study and communication of the benefits to be obtained from an advanced nanomedicine that will be made possible by molecular manufacturing [and for having] worked to develop and communicate a path from our current technology base to a future technology base that will enable advanced nanomedicine.”

Prior to his Feynman Prize win Robert shared the Lifeboat Foundation’s 2006 Guardian Award with technology legend Bill Joy. Freitas and Joy shared the Guardian award for their many years of work on mitigating risks posed by advanced technologies.

“Synbiosafe” Launched

Posted by in category: biotech/medical

The European Commission is funding a 2-year, $312,000 study on the safety and ethical aspects of synthetic biology. From the introduction part of the site:

We will pursue our objectives by means of a fact-finding mission, contribution to the European “inaugural” Conference on Synthetic Biology in Zurich (SB 3.0), an open e-forum and an international workshop. The foreseen impact of our project will be no less than to stimulate a European debate on these issues at an early stage. Past experiences, especially in the field of GM-crops, have shown the importance of an early bio-safety and ethics debate. The community recognized this need, but up to now discussions are fragmentary. Our project aims to stimulate a European debate in a proactive way. That way we will contribute to the European synthetic biology community, supplementing genuine biosafety and bioethics aspects.

Looks like a great start on addressing a very important area of concern. For a blog post of mine that goes into a bit more detail on the issue of synthetic biology and its risks, see here.

Researchers Endorse Global Early Warning System to Prevent Pandemics

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

Five evolutionary stages of pathogen progression from animals to human transmission have been identified A proposed monitoring system of viral chatter has been proposed to provide warning of new diseases before they spread to humans.

In 1999, Wolfe began field work in the jungles of Cameroon to track “viral chatter,” or the regular transmission of diseases from animals to people, usually without further spread among humans. By monitoring the habits and the blood pathologies of bushmeat hunters and their kills, Wolfe and his team have identified at least three previously unknown retroviruses from the same family as HIV, as well as promoted safe practices for handling animals and animal carcasses.

“The Cameroon project demonstrated that it’s possible to collect information on viral transmission under very difficult circumstances from these highly exposed people,” Wolfe said.

With Cameroon as a prototype and a $2.5 million National Institutes of Health Pioneer Award as seed money, Wolfe has gone on to create a network of virus-discovery projects that monitor hunters, butchers, and wildlife trade and zoo workers in some of the world’s most remote viral hotspots. The network of a dozen sites in China, the Democratic Republic of Congo, Malaysia, Laos, Madagascar and Paraguay include source locations for such emerging diseases as SARS, avian flu, Nipah, Ebola and monkeypox.

2007 DARPA Military Technology Plan: Future Medical Promise or Danger?

Posted by in categories: biological, biotech/medical, defense, lifeboat, robotics/AI

darpaachievements.jpg

DARPA (the defense advanced research projects agency) is the R&D arm of he US military for far-reaching future technology. What most people do not realize is how much revolutionary medical technology comes out of this agency’s military R&D programs. For those in need of background, you can read about the Army & DARPA’s future soldier Landwarrior program and its medtech offshoots as well as why DARPA does medical research and development that industry won’t. Fear of these future military technologies runs high with a push towards neural activation as a weapon, direct brain-computer interfaces, and drones. However, the new program has enormous potential for revolutionary medical progess as well.

It has been said technology is neutral, it is the application that is either good or evil. (It is worth a side-track to read a discussion on this concept)

The Areas of Focus for DARPA in 2007 and Forward Are:

  1. Chip-Scale Atomic Clock
  2. Global War on TerrorismUnmanned Air Vehicles
  3. Militarization of Space
  4. Supercomputer Systems
  5. Biological Warfare Defense
  6. Prosthetics
  7. Quantum Information Science
  8. Newton’s Laws for Biology
  9. Low-Cost Titanium
  10. Alternative Energy
  11. High Energy Liquid Laser Area Defense System

the potential for the destructive use of these technologies is obvious, for a a complete review of these projects and the beneficial medical applications of each visit docinthemachine.com

Better Virus Detection Device

Posted by in category: biotech/medical

From MIT’s Technology Review:

Researchers at the University of Twente, in the Netherlands, have developed an ultrasensitive sensor that could potentially be used in a handheld device to, within minutes, detect various viruses and measure their concentration. The sensor could be used to quickly screen people at hospitals and emergency clinics to control outbreaks of diseases such as SARS and the bird flu. All it would take is a tiny sample of saliva, blood, or other body fluid.

Currently available methods to detect viruses are also sensitive. But they require laborious preparation of the fluid sample and only give results after several days. Since viral diseases can spread rapidly, researchers are looking for easier, faster ways to directly detect viruses. “You want a tool on which you apply the [fluid] sample on-site and in a few minutes say whether or not the person has the SARS virus,” says Aurel Ymeti, a postdoctoral researcher in biophysical engineering and the sensor’s lead developer.

Looks promising. Hopefully this model can be extended to other nanoscale threats, like prions and genetically engineered viruses.
