Genetic analyses lay to rest conspiracy theories about death of Belgian King Albert I, who lost his life in a rock climbing accident more than 80 years ago.

Non-invasive imaging of reporter gene expression offers a powerful tool for monitoring spatial and temporal expression in live animals (or people). One limitation of such techniques is the low expression of genes driven by tissue-specific promoters. In the December 4 Proceedings of the National Academy of Sciences, Iyer et al. describe using a two-step transcriptional amplification (TSTA) approach to amplify the signal for non-invasive detection (Proc Natl Acad Sci USA 2001, 98:14595-14600).They
