Started on Nov. 30, but somewhere midway this page, turned into Dec. 30 1999.

*Technology feature : Focus on carbon nanotubes. They are the ultimate in
electronic miniaturization: tube-shaped molecules of carbon, each scarcely wider than a filament of DNA, able to conduct electricity and to be bent, cut and moulded into circuit wiring or even into new electronic devices. They are called carbon nanotubes. Philip Ball takes an in-depth look at their past, present and future. (Nature Friday 26 November 1999) http://helix.nature.com/nsu/991202/991202-1.html

*Assembling Molecules an Atom at a Time. Wilson Ho, Cornell professor of
physics, and graduate research assistant Hyojune Lee used a specially designed scanning tunneling microscope (STM) to pick up single molecules of carbon monoxide and graft them onto an iron atom to form molecules of iron carbonyl. By obtaining the new assembly's "vibrational spectrum" -- a measure of the energy in the bonds between atoms -- they verified that a chemical bond had truly been formed to produce a new molecule. (Cornell News Nov. 25, 99)

Voyage," a 1966 sci-fi B movie involving a team of intrepid doctors who were magically miniaturized and injected into the bloodstream of a critically ill diplomat to conduct lifesaving microsurgery...blah blah blah, until discusses molecular-scale processors and molecular computers and throw away computing. (LA Times Nov 29, 99)

*Theory Promotes Different Types of Intelligence. Albert Einstein was one of
the greatest thinkers the world has ever known. An extraordinary polymath who left few branches of physics untouched, he formulated theories of relativity, successfully described the nature of the universe and came up with the most famous equation in the world. David Beckham is the footballer whose skill and precision have made him one of the most gifted sportsmen of his generation. His looks and Spice Girl wife add to the allure, but it is his pure talent that makes him a firm favourite as European Footballer of the Year, to be decided next month. Who is the more intelligent? (Fox Nov 28,99)

*Using Neural Networks. These programs can be taught to think like chemists
about some kinds of problems.Inspired by theories of the brain in the 1940s, programmers devised neural networks, mathematical models that rely on varying the strength of connections between internal processing elements to interpret data. Knowing how to build a neural network is one thing, but knowing how to leverage it into a useful application is something much more important.

*Forum on Genetically-Modified Foods. The Food and Drug Administration holds
a public hearing in Washington today to discuss the practice of using genetics to alter crops. Experts say the technology -- already used with corn, soybeans and many other foods -- is just as safe as accepted plant-breeding methods. But following protests in Britain, some Americans are raising questions about genetically-modified foods. In genetic engineering, DNA from bacteria and other organisms is injected into food crops to make them more resistant to pests or to give them other useful properties. Hear the audio on NPR.

*The search for smart genes. A British scientist continues his bold quest
for patterns of intelligence in our DNA. It is one of the most important predictors of financial and social success. It helps determine where you work, where you live, whether you wind up in jail. It can be measured with great precision, and it changes very little over a lifetime. It is substantially influenced by your genes. Or is it?
