HeLa. Reconstructing an Immortal Bio
No full textHenrietta Lacks died of cervical cancer in 1951 at 31, but a cell line from her tissues is still alive and reproducing for scientific purposes. Her dramatic biography and her fundamental (although unwitting) contribution to the development of scientific knowledge went unnoticed until Rebecca Skloot's "The immortal life of Henrietta Lacks" [New York, Random House, 2010, 384 pp.] was published. The political, scientific, social and technological entanglement of Henrietta's account by Skloot is an original and vivid science narrative of clear relevance for Science and Technology Studies. Stemming from Henrietta's story and Skloot's book, Stefano Crabu, Mauro Turrini, Marialuisa Lavitrano and Sara Casati reflect and discuss on the relation between society and medical research, its ethical dilemmas, as well as on the way technoscientific processes can be accounted for

Le «buone letture». 2. Giovanni Casati
No full textIl saggio è costituito da due parti, la prima delle quali, dedicata alla fondazione della Federazione italiana delle biblioteche circolanti cattoliche, è stata pubblicata nel precedente numero dei «Nuovi Annali», XXVII (2013), pp. 137-163. In questa seconda parte viene delineata la figura intellettuale di Giovanni Casati, che diresse la «Rivista di letture» dal 1912 al 1944, trasformando il periodico della Federazione in una rivista impegnata nella divulgazione della cultura cattolica. A questo impegno militante Casati fece corrispondere un intenso programma editoriale, che trovò espressione nella pubblicazione di saggi letterari, di manuali e opere repertoriali.The study consists of two parts; the first is dedicated to the history of the Federazione italiana delle biblioteche circolanti cattoliche since its foundation (1904) up to 1912 and was published in the previous volume of the «Nuovi Annali », XXVII (2013), pp. 137-163. In this second part, the author outlines the intellectual figure of Giovanni Casati, who directed the «Rivista di letture» from 1912 to 1944, transforming the magazine of the Federation in a journal engaged in the spreading of Catholic culture. To this militant engagement Casati matched an intense publishing program, which found its expression in the publication of literary essays, manuals and reference works

Caravaggio a Milano, 1951. Il dibattito sulla carta stampata: critica e militanza
No full textLa mostra dedicata a Caravaggio, che si tenne a Milano nella primavera del 1951 a cura di Roberto
Longhi, rappresentò un momento culminante degli studi caravaggeschi della prima metà del XX secolo
e segnò uno spartiacque nella storia critica del maestro lombardo. In questa sede si prendono in esame
testimonianze sinora poco valutate, ovvero le recensioni e gli articoli apparsi sulla stampa periodica non
specialistica e sui quotidiani, che offrono materia per una riflessione più ampia sul tema del realismo.
Si tratta di attestazioni cariche della vivacità del momento storico, di cui traducono polemiche,
sensazioni, opinioni in grado di restituire la tensione tipica dell’evento espositivo. Tra gli attori di questa
complessa vicenda si trovano editorialisti, pubblicisti, letterati e critici militanti, quali Leonardo Borgese,
Alfredo Mezio, Mario De Micheli, Elio Vittorini, ma anche registi e documentaristi come Umberto
Barbaro, che fu collaboratore di Longhi.The exhibition dedicated to Caravaggio, which was held in Milan in the spring of 1951 by Roberto Longhi,
was a culmination of Caravaggio studies in the first half of the twentieth century and marked a watershed
in the history of criticism of the Lombard master. Here the author examines some unappreciated
evidences, that is the reviews and the articles published in periodicals and newspapers, which offer
material for a broader reflection on the theme of realism. They are proof of the liveliness of the historic
moment, of which translate controversy, feelings, opinions that can return the typical tension of the
exhibition. Among the actors of this complex situation there are columnists, publicists, writers and critics,
such as Leonardo Borgese, Alfredo Mezio, Mario De Micheli, Elio Vittorini, but also directors and
documentarians like Umberto Barbaro

However, the resemblance of <i>R. gilbertus</i> with several species of this genus suggests the generic attribute. Another character suggestive of the genus is the striated protoconch (Figs. 23, 29). Only few of the <i>Rhinus</i> that have elongated shell; most has a more globose shape. The elongated-shaped <i>Rhinus</i> (Simone, 2006), <i>R. gilbertus</i> resembles <i>R. constrictus</i> (Pfeiffer, 1841), from NE Brazil, differing in being more slender (width/length ratio of ~40%, against ~62% of that species); it also resembles <i>R. evelinae</i> Leme, 1986, from São Paulo, and <i>R. obeliscus</i> Haas, 1936, from Santa Catarina. It differs in having a slightly more rounded outline, as that two species are still more elongated (ratio of both species ~35%), and two fewer whorls. <i>R. gilbertus</i> is the most elongated <i>Rhinus</i> from the NE Brazil, as elongated shape is more common in SE Brazilian species. A young specimen is shown in Fig. 29, displaying a different shape.</p>Published as part of <i>Simone, Luiz Ricardo L. & Casati, Rafael, 2013, New land mollusk fauna from Serra da Capivara, Piauí, Brazil, with a new genus and five new species (Gastropoda: Orthalicoidea, Streptaxidae, Subulinidae), pp. 145-158 in Zootaxa 3683 (2)</i> on pages 153-154, DOI: 10.11646/zootaxa.3683.2.4, <a href="http://zenodo.org/record/218653">http://zenodo.org/record/218653</a>
