Smelters refine aluminum ore, but not iron ore, with electricity. A new electrolytic process for refining iron ore could save vast amounts of greenhouse gases.

“Yes, but…” is the word from the frontiers of physics. The world’s largest atom smasher has blasted protons against each other with such enormous energy that they have — apparently — appeared in the debris of decaying particles. At last, matter can have mass!

Biology operates on the nanometer scale, and now ultra-small technology is producing monster benefits for genetic analysis, cell biologists, and the treatment of blinding glaucoma.

The Spallation Neutron Source, a mammoth science project involving the collaboration of six national laboratories, is scheduled to be completed 2006.

Edward Teller helped invent the hydrogen bomb, then pushed missile defense. By public advocacy and secret research, he changed the 20th century.

Nanobelts join nanotubes in the world of nanotechnology.
