October 2000 cover
Cover: Revealed here with a fluorescent dye, a nerve cell's network of dendrites gathers information from other nerve cells and channels the integrated signal to the cell body. In the news story that begins on page 19, we report new findings on how signals from the longest dendrites are able to reach the center of the nerve cell, even though dendrites behave like leaky pipes.

Szilard as Inventor: Accelerators and More
In his Berlin and London days between the world wars, Leo Szilard thought about household refrigerators and nuclear chain reactions. He also invented many of the central features of the accelerators that would take the study of nuclear and particle physics to high energies -- Valentine L. Telegdi

Blue Diode Lasers
Layered light-emitting heterostructures based on gallium nitride are quite different from their gallium arsenide cousins. Empirical development is advancing rapidly, and fundamental understanding is struggling to catch up -- Noble M. Johnson, Arto V. Nurmikko, and Steven P. DenBaars

Physics in Latin America Comes of Age
In just over 50 years, the physics community throughout Latin America has grown to include advanced education programs, major research facilities, and industrial development. An aggressive program for science and technology may lead to a flourishing epoch in the next century -- José Luis Morán-López
