The artwork on the cover were taken from the ‘Art and Crystallography’ exhibit at the IUCr Congress in Florence. 1. In this ‘infinite’ golden section net where the interrelations between pentagons, pentagonal stars, and Penrose rhombs constitute a self-similar structure with a golden ratio as the scale factor we can easily recognize the underlying model of a decagonal quasicrystalline cluster. (Teja Krasek) 2. Photomontage of an electron diffraction image from a single X-ray experiment and a famous masterpiece “Last Judgment” of G. Vasari and F. Zuccari in the cupola of Duomo in Florence (Natalia Panina). 3. A model of anthocyanin, representative of a class of molecules found in fruit and grapes which gives red wine its characteristic color. The sculpture was carved from a 4 inch (10 cm) solid block of american walnut (Edgar Meyer). 4. A. portion of a polished stainless steel molecular sculpture of the trp operator (Byron Rubin) 5. “Through the Crystal” was inspired by the wonderful landscape of the Canary Islands. We see a young woman looking through a crystal blending the Great Bear in the night sky with the diffraction pattern of the crystal. (Laura Cañadillas, Oscar Fabelo and Jorge Pasán).
