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.

Iranian official: If threatened, we will use nuclear weapons

Posted by in categories: geopolitics, nuclear weapons

From Ynet News:

Iran’s chief nuclear envoy Ali Larijani said on Friday that Iran is committed to the peaceful use of nuclear technology but warned the situation could change if his country is threatened.” We oppose obtaining nuclear weapons and we will peacefully use nuclear technology under the framework of the Nonproliferation Treaty, but if we are threatened, the situation may change,” He told a news conference after two days of talks in Beijing. Iran’s nuclear chief said his country has produced and stored 250 tons of the gas used as the feedstock for uranium enrichment, state-run television reported Friday.Vice President Gholamreza Aghazadeh, who is also the head of the Atomic Energy Organization of Iran, said Iran has kept the uranium hexaflouride gas, or UF-6, in underground tunnels at a nuclear facility in Isfahan to protect it from any possible attack.“Today, we have produced more than 250 tons of UF-6. Should you visit Isfahan, you will see we have constructed tunnels that are almost unique in the world,” State-run television quoted Aghazadeh as saying.
This is horrible news. Iran’s supreme ruler supposedly issued a fatwa against the development of nuclear weapons, but it’s clear that the country wants them. One can only speculate at the chaos that could be caused when Iran threatens Israel or the United States with nuclear weapons.

Interview with Dr. Alan Goldstein

Posted by in category: nanotechnology

Over at Accelerating Future, a new interview between Michael Anissimov (a.k.a. me), and Dr. Alan Goldstein, a member of our Scientific Advisory Board who is concerned about the dangers of bionanotechnology. Here is an excerpt from the first part of the interview:

Michael Anissimov: How do you define synthetic biology (A-life)?

Dr. Alan Goldstein: It is crucial to this discussion that people recognize that Synthetic Biology is not the same as Artificial Life. I have spent a great deal of time trying to explain the difference in terms that are understandable to non-technical folks.

Egypt’s President Hints at Nuke Development

Posted by in categories: geopolitics, nuclear weapons

From Ynet News:

SHARM E-SHEIKH – Is Egypt declaring its intentions to develop nuclear weapons? Thus it appeared in a speech delivered by Egyptian President Hosni Mubarak Thursday on the occasion of meeting with Prime Minister Ehud Olmert in Sharm e-Sheikh.

“We don’t want nuclear weapons,” Mubarak stated, “But since they appear highly present in the area, we must defend ourselves.”

Hawking hopes to go into space in 2009

Posted by in category: space

From Yahoo News:

Astrophysicist Stephen Hawking says he wants to undertake a zero-gravity flight aboard an aircraft this year as a precursor to a journey into space.

“This year I’m planning a zero-gravity flight and to go into space in 2009,” he was quoted as saying in The Daily Telegraph newspaper.

From ABC News:

WASHINGTON, Jan. 4, 2007 — North Korea appears to have made preparations for another nuclear test, according to U.S. defense officials.

“We think they’ve put everything in place to conduct a test without any notice or warning,” a senior U.S. defense official told ABC News.

The Sorcerer’s Apprentice

Posted by in category: nanotechnology

On Edge.org, 160 brilliant scientists and thinkers were asked, “what are you optimistic about?” Gregory Cochran, a professor of anthropology at the University of Utah, chose to speak about self-replicating manufacturing:

In the sweat of thy face shalt thou eat bread”—it has always been that way.

Most men have been slaves of necessity, while the few who were not lived by exploiting others who were. Although mechanization has eased that burden in the advanced countries, it is still the case for the majority of the human race. Limited resources (mainly fossil fuels), as well as negative consequences of industrialization such as global warming, have made some people question whether American living standards can ever be extended to most of the human race. They’re pessimists, and they’re wrong.

UK Government Report Talks Robot Rights

Posted by in categories: robotics/AI, supercomputing

In an important step forward for acknowledging the possibility of real AI in our immediate future, a report by the UK government that says robots will have the same rights and responsibilities as human citizens. The Financial Times reports:

The next time you beat your keyboard in frustration, think of a day when it may be able to sue you for assault. Within 50 years we might even find ourselves standing next to the next generation of vacuum cleaners in the voting booth. Far from being extracts from the extreme end of science fiction, the idea that we may one day give sentient machines the kind of rights traditionally reserved for humans is raised in a British government-commissioned report which claims to be an extensive look into the future. Visions of the status of robots around 2056 have emerged from one of 270 forward-looking papers sponsored by Sir David King, the UK government’s chief scientist.

The paper covering robots’ rights was written by a UK partnership of Outsights, the management consultancy, and Ipsos Mori, the opinion research organisation. “If we make conscious robots they would want to have rights and they probably should,” said Henrik Christensen, director of the Centre of Robotics and Intelligent Machines at the Georgia Institute of Technology. The idea will not surprise science fiction aficionados.

It was widely explored by Dr Isaac Asimov, one of the foremost science fiction writers of the 20th century. He wrote of a society where robots were fully integrated and essential in day-to-day life.In his system, the ‘three laws of robotics’ governed machine life. They decreed that robots could not injure humans, must obey orders and protect their own existence – in that order.

Hypersonic Cruise Missile

Posted by in category: military

From Popular Science, a project that introduces a powerful kinetic weapon to the U.S. military arsenal:

When the order comes, the sub shoots a 65-ton Trident II ballistic missile into the sky. Within 2 minutes, the missile is traveling at more than 20,000 ft. per second. Up and over the oceans and out of the atmosphere it soars for thousands of miles. At the top of its parabola, hanging in space, the Trident’s four warheads separate and begin their screaming descent down toward the planet. Traveling as fast as 13,000 mph, the warheads are filled with scored tungsten rods with twice the strength of steel. Just above the target, the warheads detonate, showering the area with thousands of rods-each one up to 12 times as destructive as a .50-caliber bullet. Anything within 3000 sq. ft. of this whirling, metallic storm is obliterated.

If Pentagon strategists get their way, there will be no place on the planet to hide from such an assault. The plan is part of a program — in slow development since the 1990s, and now quickly coalescing in military circles — called Prompt Global Strike. It will begin with modified Tridents. But eventually, Prompt Global Strike could encompass new generations of aircraft and armaments five times faster than anything in the current American arsenal. One candidate: the X-51 hypersonic cruise missile, which is designed to hit Mach 5 — roughly 3600 mph. The goal, according to the U.S. Strategic Command’s deputy commander Lt. Gen. C. Robert Kehler, is “to strike virtually anywhere on the face of the Earth within 60 minutes.”
