Il tenace filo magico di Paolo Rossi: 1957-2006
No full textThis article examines the development of Paolo Rossi’s studies regarding magic, from his monograph on Bacon in the 1950s until his last volume, Il Tempo dei Maghi. His unpublished letters, with Antonio Banfi and Eugenio Garin, reflect the interests that characterized Rossi’s work -- not only historiographic, studying Renaissance magical thinking in its relation to the scientific revolution, but also frankly theoretical in nature. Studying all those moments of crisis and transition that present in renewed form the old antithesis between reason and magism, Rossi shows the extreme vitality of magical thinking and its ever-present challenge to the way of thinking that emerged at the beginning of the modern age

Characterization and functional complementation of a nonlethal deletion in the chromosome of a beta-glycosidase mutant of Sulfolobus solfataricus
No full textLacS(-) mutants of Sulfolobus solfataricus defective in beta-glycosidase activity were isolated in order to explore genomic instability and exploit novel strategies for transformation and complementation. One of the mutants showed a stable phenotype with no reversion; analysis of its chromosome revealed the total absence of the beta-glycosidase gene (lacS). Fine mapping performed in comparison to the genomic sequence of S. solfataricus P2 indicated an extended deletion of approximately 13 kb. The sequence analysis also revealed that this chromosomal rearrangement was a nonconservative transposition event driven by the mobile insertion sequence element ISC1058. In order to complement the LacS(-) phenotype, an expression vector was constructed by inserting the lacS coding sequence with its 5' and 3' flanking regions into the pEXSs plasmid. Since no transformant could be recovered by selection on lactose as the sole nutrient, another plasmid construct containing a larger genomic fragment was tested for complementation; this region also comprised the lacTr (lactose transporter) gene encoding a putative membrane protein homologous to the major facilitator superfamily. Cells transformed with both genes were able to form colonies on lactose plates and to be stained with the beta-glycosidase chromogenic substrate X-Gal (5-bromo-4-chloro-3-indoyl-beta-D-galactopyranoside)
