A better atomic force microscope from Japan:

“A new type of atomic force microscope (AFM) has been developed that can “fingerprint” the chemical identity of individual atoms on a material’s surface. This is one step ahead of existing AFMs, which can only detect the position of atoms. The device determines local composition and structure using a precise calibration method, and can even be used to manipulate specific atomic species. The team demonstrated their “fingerprinting” technique by using an atomic force microscope (AFM) to distinguish atoms of tin (blue) and lead (green) deposited on a silicon substrate (red).”

“The importance of the space sector can be emphasized by the number of spacecrafts launched. In the period from 1957 till 2005, 6376 spacecraft have been launched at an average of 133 per year. The has been a decrease in the number of spacecrafts launched in the recent years with 78 launched in 2005. Of the 6378 launches, 56.8% were military spacecrafts and 43.2 were civilian. 245 manned missions have been launched in this period. 1674 communication or weather satellites were also launched. The remaining spacecraft launches has been exploration missions.”

Like the Lifeboat Foundation, The Bulletin of Atomic Scientists is an organization formed to address catastrophic technological risks. In catastrophic risk management, vision and foresight are essential. You take at technological, social, and political trends which are happening today — for example, steps towards mechanical chemistry, increasing transparency, or civil atomic programs — and brainstorm with as many experts as possible about what these trends indicate about what is coming 5, 10, or 20 years down the road. Because catastrophic risk management is a long-term enterprise, one where countermeasures are ideally deployed before a threat has even materialized, the further and more clearly you try to see into the future, the better.

Traditionally, The Bulletin has focused on the risk from nuclear warfare. Lately, they have expanded their attention to all large-scale technological risks, including global warming and future risks from emerging technologies. However, the language and claims used on their website show that the organization’s members are only just beginning to get informed about the emerging technologies, and the core of their awareness still lies with the nuclear issue.

From The Bulletin’s statement regarding their decision to move the clock 5 minutes to midnight, from the “emerging technologies” section specifically:

From the Unemumerated blog, this piece was originally written in 1993:

Using materials native to space, instead of hauling everything from Earth, is crucial to future efforts at large-scale space industrialization and colonization. At that time we will be using technologies far in advance of today’s, but even now we can see the technology developing for use here on earth.

There are a myriad of materials we would like to process, including dirty organic-laden ice on comets and some asteroids, subsurface ice and the atmosphere of Mars, platinum-rich unoxidized nickel-iron metal regoliths on asteroids, etc. There are an even wider array of materials we would like to make. The first and most important is propellant, but eventually we want a wide array of manufacturing and construction inputs, including complex polymers like Kevlar and graphite epoxies for strong tethers.

The advantages of native propellant can be seen in two recent mission proposals. In several Mars mission proposals[1], H2 from Earth or Martian water is chemically processed with CO₂ from the Martian atmosphere, making CH4 and O₂ propellants for operations on Mars and the return trip to Earth. Even bringing H2 from Earth, this scheme can reduce the propellant mass to be launched from Earth by over 75%. Similarly, I have described a system that converts cometary or asteroidal ice into a cylindrical, zero-tank-mass thermal rocket. This can be used to transport large interplanetary payloads, including the valuable organic and volatile ices themselves into high Earth and Martian orbits.

There were several significant developments and announcements that were nanotechnology related.

The UK Ideas Factory Sandpit announced three ambitious, but in my opinion achievable projects in the 2–5 year timeframe.

1. A system with software based control for the assembly of DNA oligomers, nanopartices and other small molecules. This would be a significant advance over current DNA synthesis if they are successful.

2. Computer-directed actuators with sub-angstrom precisions that is based upon novel surface-bound, reconfigurable nanoscale building blocks and a prototype computer-controlled matter manipulator (akin to a nanoscale conveyor belt)

From United Press International:

DAYTON, Calif., Dec. 20 (UPI) — The U.S. Army awarded a $15 million contract for the development of a new type of lightweight composite armor based on nanotechnology.

The pact awarded to the University of Dayton Research Institute (UDRI) this week will lead to new materials that can be used in vehicles and body armor.

“This is not a ground-level academic study project,” UDRI engineer Brian Rice said. “We are actually working with two Ohio companies to create a product that, if it tests out well, could show up in Iraq next year.”

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.
