How long do we have? — Regulate armed robots before it’s too late

NewScientist — March 10, 2009, by A. C. Grayling

IN THIS age of super-rapid technological advance, we do well to obey the Boy Scout injunction: “Be prepared”. That requires nimbleness of mind, given that the ever accelerating power of computers is being applied across such a wide range of applications, making it hard to keep track of everything that is happening. The danger is that we only wake up to the need for forethought when in the midst of a storm created by innovations that have already overtaken us.

We are on the brink, and perhaps to some degree already over the edge, in one hugely important area: robotics. Robot sentries patrol the borders of South Korea and Israel. Remote-controlled aircraft mount missile attacks on enemy positions. Other military robots are already in service, and not just for defusing bombs or detecting landmines: a coming generation of autonomous combat robots capable of deep penetration into enemy territory raises questions about whether they will be able to discriminate between soldiers and innocent civilians. Police forces are looking to acquire miniature Taser-firing robot helicopters. In South Korea and Japan the development of robots for feeding and bathing the elderly and children is already advanced. Even in a robot-backward country like the UK, some vacuum cleaners sense their autonomous way around furniture. A driverless car has already negotiated its way through Los Angeles traffic.

The Disclosure Project May 9th 2001 National Press Club Conference and DEAFENING SILENCE: Media Response to the May 9th Event and its Implications Regarding the Truth of Disclosure by Jonathan Kolber

On Wednesday, May 9th 2001, over twenty military, intelligence, government, corporate and scientific witnesses came forward at the National Press Club in Washington, DC to establish the reality of UFOs or extraterrestrial vehicles, extraterrestrial life forms, and resulting advanced energy and propulsion technologies.

Nanotech Development: You Can’t Please All of the People, All of the Time

Posted by in categories: ethics, nanotechnology, policy

Abstract

What counts as rational development and commercialization of a new technology—especially something as potentially wonderful (and dangerous) as nanotechnology? A recent newsletter of the EU nanomaterials characterization group NanoCharM got me thinking about this question. Several authors in this newsletter advocated, by a variety of expressions, a rational course of action. And I’ve heard similar rhetoric from other camps in the several nanoscience and nanoengineering fields.

We need a sound way of characterizing nanomaterials, and then an account of their fate and transport, and their novel properties. We need to understand the bioactivity of nanoparticles, and their effect in the environments where they may end up. We need to know what kinds of nanoparticles occur naturally, which are incidental to other engineering processes, and which we can engineer de novo to solve the world’s problems—and to fill some portion of the world’s bank accounts. We need life-cycle analyses, and toxicity and exposure studies, and cost-benefit analyses. It’s just the rational way to proceed. Well who could argue with that?

Could Spider Silk Save Your Life?

Posted by in categories: ethics, military, nanotechnology

Sometimes what may save your life can come from the most unsuspecting places. Then sometimes, what can save your life in one circumstance may be highly risky, or at least technologically premature, in another. Lifeboat Foundation is about making those distinctions regarding emerging technologies and knowing the difference.

MIT scientists from the Institute for Soldier Nanotechnologies announced in January 2007 they had reached an elusive engineering milestone. They had successfully created a synthetic material with the same properties of spider silk.1 The combination of elasticity and strength of spider silk has been a long sought after target for synthetic manufacturing for improving materials as diverse as packaging, clothing, and medical devices. Using tiny clay disks approximately one billionth of a meter, these nanocrystals combined with rubber polymer create the stretchy but strong polymer nanocomposite.

The use of nanocomposites for the production of packaging materials or clothing seems to be a relatively safe and non-controversial because materials remain outside the body. The United States military has already indicated, according to one source, their desire to use the material for military uniforms and to improve packaging for those lovely-tasting MREs.2 In fact, this is why the Army-funded Institute for Soldier Nanotechnology is supporting the research—to develop pliable but tough body armor for soldiers in combat. Moreover, imagine, for example, a garbage bag that could hold an anvil without breaking. The commercial applications may be endless—but there should be real concern regarding the ways in which these materials might be introduced into human bodies.

Although this synthetic spider silk may conjure up images of one day being able to have the capabilities of Peter Parker or unbreakable, super-strength bones, there are some real concerns regarding the potential applications of this technology, particularly for medical purposes. Some have argued that polymer nanocomposite materials could be used as the mother of all Band-Aids or nearly indestructible stents. For hundreds of years, spider silks have been thought to have great potential for wound covering. In general, nanocomposite materials have been heralded for medical applications as diverse as bone grafts to antimicrobial surfaces for medical instruments.
