Drosophila telomeres comprise DNA sequences that differ dramatically from those of other eukaryotes. Telomere functions, however, are similar to those found in telomerase‐based telomeres, even though the underlying mechanisms may differ. Drosophila telomeres use arrays of retrotransposons to maintain chromosome length, while nearly all other eukaryotes rely on telomerase‐generated short repeats. Regardless of the DNA sequence, several end‐binding proteins are evolutionarily conserved. Away from the end, the Drosophila telomeric and subtelomeric DNA sequences are complexed with unique combinations of proteins that (...) also modulate chromatin structure elsewhere in the genome. Maintaining and regulating the transcriptional activity of the telomeric retrotransposons in Drosophila requires specific chromatin structures and, while telomeric silencing spreads from the terminal repeats in yeast, the source of telomeric silencing in Drosophila is the subterminal arrays. However, the subterminal arrays in both species may be involved in telomere–telomere associations and/or communication. BioEssays 30:25–37, 2008. © 2007 Wiley Periodicals, Inc. (shrink)

"The demonization of the radical right ill serves us when now, more than ever before, it is vitally important to know all we can about this esoteric milieu's nature and potentialities…by…demonizing the many, we cloak the few, and, however unwittingly, facilitate the existence of evil in the world." —From the Introduction by Jeffrey Kaplan White power groups are universally vilified and feared. But to better understand the threat they pose, scholars and activists must try to better understand their disturbing ideas (...) and practices. In this controversial volume, Jeffrey Kaplan brings to light the workings of white supremacy movements in the United States and Europe in the years since World War II. The first half of the Encyclopedia is made up of over 100 entries—many of them essay-length—describing the people, groups and themes that make up the radical racist right. Some of the entries are written by movement activists themselves, providing useful insider accounts. The second half contains original resources circulated within the movement, each prefaced and placed in scholarly context by the editor. These documents, although offending, are invaluable to researchers and often available nowhere else. Cross-references and an index make the information easily accessible. For scholars of race, religion, politics or social movements, the Encyclopedia of White Power is an essential resource. (shrink)
