Article on N-acylethanolamine signaling in tobacco and how it is mediated by a membrane-associated, high-affinity binding protein.

Article on phenylpropanoid compounds and disease resistance in transgenic tobacco with altered expression of L-phenylalanine ammonia-lyase.

Article describing the authors' tour through Riddarhyttan, Sweden, to visit the areas where cerium and cobalt were discovered. Maps and photographs of pertinent locations are located as well as a history of the area and the elements discovered there.

Article describing the discovery of Vanadium and tracing the footsteps of the discoverers.

This article presents the results of a dense and intensive X-ray and optical monitoring of the narrow-line Seyfert 1 galaxy NGC 4051 carried out in 2000.

First page of The Hexagon of Alpha Chi Sigma. The blue cover features a black and white drawing of a medieval knight wearing mail and a tunic with a cross motif. He is holding a shield that bears the image of a stone building with flames shooting out of the roof. The word "Riddarhyttan" appears on a banner above the knight's head. Two photographs are arranged to the left of the knight, with text and an image of a computer mouse to the right. The next page includes a table of contents, an editorial, and a list of contributors. Near the bottom of this second page is a piece labeled "On the Cover," which describes the previous page.

This article presents the intrinsic spectral energy distribution of the narrow-line Seyfert 1 galaxy Ark 564, constructed with contemporaneous data obtained during a multiwavelength, multisatellite observing campaign in 2000 and 2001.
