Advanced Materials extends its congratulations to A. B. Kotlyar, D. Porath, and co-workers, whose cover for issue 15, 2005 was voted to be the best of the year. The cover (left) is an artistic view, designed by Noam Hamou, of a guanine (G)-wire, probably a G4-DNA nanowire, where the schematic spiral and tetrad are emerging from a single molecule deposited on a mica surface, as imaged by AFM. The long, monomolecular G-wires self-fold to form structures of consecutive guanine tetrads with and without metal ions in the inner channel of the molecule. The continuity of the molecule backbone and its improved stiffness suggest that this single DNA-based structure might be useful for nanoelectronic applications.

Our congratulations also go to Seiichi Furumi, who was drawn from among the registered voters, and will receive a book of his choice or a free one-year subscription to Advanced Materials.

Thank you very much to all participants; we hope you continue to enjoy Advanced Materials, both inside and out!
