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.

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.

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.

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.

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.

Two of Britain’s leading environmental thinkers say it is time to develop a quick technical fix for climate change. Writing in the journal Nature, Science Museum head Chris Rapley and Gaia theorist James Lovelock suggest looking at boosting ocean take-up of CO₂.
…
Floating pipes reaching down from the top of the ocean into colder water below move up and down with the swell.

As the pipe moves down, cold water flows up and out onto the ocean surface. A simple valve blocks any downward flow when the pipe is moving upwards.

Colder water is more “productive” — it contains more life, and so in principle can absorb more carbon.

Finally some practical solutions are being introduced to mitigate global warming. The BBC article mention the US company, Atmocean, that is already testing such a system.

Read the articles from BBC or the New York Times based on the same article from Nature.

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.

After all, the march to the Singularity will go a lot slower without a reliable power grid.

A new biosensor developed at the Georgia Tech Research Institute (GTRI) can detect avian influenza in just minutes. In addition to being a rapid test, the biosensor is economical, field-deployable, sensitive to different viral strains and requires no labels or reagents.

This kind of technology could be applied to real time monitoring of other diseases as well.

“We can do real-time monitoring of avian influenza infections on the farm, in live-bird markets or in poultry processing facilities,” said Jie Xu, a research scientist in GTRI’s Electro-Optical Systems Laboratory (EOSL)
