Several ICTP scientists have received notice in Science and Nature. Filippo Giorgi, head, and Raquel Francisco, staff scientist, ICTP's Weather and Climate Group, were recently quoted in a Science news article (23 June 2000, p. 2113) that discusses the findings of the U.S. government report, "Climate Change Impacts on the United States." The report assesses the potential impact of global warming on various regions of the USA based on the output of the best available climate models. Giorgi and Francisco spoke about the reliability and uncertainty of climate models, especially at the regional level. Erio Tosatti, professor at the International School for Advanced Studies (SISSA) and consultant with the ICTP Condensed Matter Physics Group, co-authored a research article with Santi Prestipino, SISSA and Italian National Institute for the Physics of Matter (INFM), "Weird Gold Nanowires," Science (28 July 2000), p. 561-563. Amos Maritan, Christian Micheletti and Antonio Trovato, who hold joint appointments with SISSA and ICTP, co-authored a research article, "Optimal Shapes of Compact Strings," Nature (20 July 2000), p. 287-290.
