The only comprehensive treatment available, it will be the definitive resource for amateur naturalists as well as professionals with an interest in this rapidly changing biogeographical region.

Can a virus change the world? Why are new viruses emerging? In this book, Ignacio López-Goñi takes us into the world of virology: origin, characteristics, creation of new viruses, pandemics, the best known viruses, and more.

In previous volumes in this series, Advances in Metal and Semiconductor Clusters, the focus has been on atomic clusters of metals, semiconductors and carbon. Fundamental gas phase studies have been surveyed, and most recently scientists have explored new materials which can be produced from clusters or cluster precursors. In this latest volume, the focus shifts to clusters composed primarily of non-metal molecules or atoms which have one or more metal atoms seeded into the cluster as an impurity. These clusters provide model systems for metal ion solvation processes and metal-ligand...

La materia oscura es el gran enigma de la ciencia del siglo xxi. Si le preguntas a un físico: «¿Qué queda por descubrir, ahora que también se ha encontrado el bosón de Higgs?», casi seguro que responderá: «prácticamente todo». Sí, porque la materia ordinaria representa solo el 5 por ciento de nuestro universo. El resto consistiría en energía oscura y materia oscura, que representaría casi el 90 por ciento de la masa total. Por cada gramo de materia ordinaria, habría, en algún lugar a nuestro alrededor, 9 de materia oscura. Aun así, algunos científicos afirman que no existe. ...
