On quicksilver, or mercury, a self-cleaving DNA discovered in vivo and containing imidazole and amine groups responds selectively and with high sensitivity, as D. M. Perrin et al. reveal in their Communication on page 4346 ff. The cover picture shows the formula of the DNAzyme along with the periodic table, indicating elements that have been tested (red bars) and the Hg cleaving efficiency (green).
