Today, the University of Colorado at Boulder made an announcement regarding a very promising technology:

Known as optical frequency comb spectroscopy, the technique is powerful enough to sort through all the molecules in human breath and sensitive enough to distinguish rare molecules that may be biomarkers for specific diseases

Combined with other rapid-response technologies, this could be part of the detection side of a BioShield, a technological immune system for humanity.

The optical frequency comb is a very precise laser for measuring different colors, or frequencies, of light, said Ye. Each comb line, or “tooth,” is tuned to a distinct frequency of a particular molecule’s vibration or rotation, and the entire comb covers a broad spectral range — much like a rainbow of colors — that can identify thousands of different molecules.

Many of you have recently read that a research team at the University of Illinois led by Min-Feng Yu has developed a process to grow nanowires of unlimited length. The same process also allows for the construction of complex, three-dimensional nanoscale structures. If this is news to you, please refer to the links below.

It’s easy to let this news item slip past before its implications have a chance to sink in.

Professor Yu and his team have shown us a glimpse of how to make nanowire based materials that will, once the technology is developed more fully, allow for at least two very significant enhancements in materials science.

1. Nanowires that will be as long as we want them to be. The only limitations that seem to be indicated are the size of the “ink” reservoir and the size of spool that the nanowires are wound on. Scale up the ink supply and the scale up size of the spool and we’ll soon be making cables and fabric. Make the cables long enough and braid enough of them them together and the Space Elevator Games may become even more exciting to watch.

Via the Global Security Newswire:

WASHINGTON — The United Kingdom announced today that it had finished destroying thousands of decades-old chemical weapons (see GSN, June 6, 2002).

The elimination of the last known “legacy” munitions containing agents such as sulfur mustard and phosgene is in keeping with the nation’s obligations under the Chemical Weapon Convention, a Defense Ministry spokesman said.

The British military began using chemical weapons in World War I, and maintained an offensive program until 1956. The Porton Down research facility was already regularly destroying weapons when the treaty entered into force in the United Kingdom in 1997. A total of 7,000 munitions have been destroyed since 1989, with work ending on March 7.
