On my desk to read today? A new report of a screen performed at the DRSC and focused on somatic homolog pairing. For a related study, check out the Joyce et al. paper mentioned in a previous post.
Bateman et al. (2012) "A Genome-Wide Screen Identifies Genes That Affect Somatic Homolog Pairing in Drosophila" in G3 (Genes, Genomes and Genetics).
