Giornale di Fisica, Vol. 56, N. 4 (2015)
Giornale di Fisica È online e in distribuzione il quarto numero del vol. 56 del 2015.
In apertura un articolo storico di L. Gariboldi che, analizzando i documenti dell'Archivio Nobel con più di cinquant'anni, ricostruisce i motivi del mancato conferimento del Premio Nobel nei tre casi degli italiani Bruno Rossi, Beppo Occhialini, e il gruppo Conversi, Pancini e Piccioni, per la fisica dei raggi cosmici. Segue un articolo di didattica di F. Operetto sull'introduzione a livello della scuola secondaria dell'effetto Compton, e poi ancora per la didattica un articolo di S. Leccia et al. con una proposta innovativa per l'insegnamento delle onde meccaniche mescolando un contesto tradizionale, come lo studio di un suono emesso da un diapason, con uno insolito, come lo studio del suono prodotto dal sole. In chiusura, come ormai di consuetudine per l'ultimo numero dell'anno, un articolo sul Premio Nobel per la Fisica 2015, in cui l'autore, A. Bettini, ripercorre brevemente le tappe fondamentali della fisica dei neutrini.

La Rivista del Nuovo Cimento Supernova neutrinos: Production, oscillations and detection

The present status of modelling the neutrino physics and signal formation in collapsing and exploding stars has been reviewed, and the capability of current and planned large underground neutrino detectors to yield faithful information of the time and flavor-dependent neutrino signal from a future Galactic supernova has been discussed. The observable neutrino burst would provide a benchmark for fundamental supernova physics with unprecedented richness of detail. Exploiting the treasure of the measured neutrino events requires a careful discrimination of source-generated properties from signal features that originate on the way to the detector. As for the latter, self-induced flavor conversions associated with neutrino-neutrino interactions that occur in the deepest stellar regions has been discussed, as well as matter effects that modify the pattern of flavor conversions in the dynamical stellar envelope, neutrino-oscillation signatures that result from structural features associated with the shock-wave propagation and turbulent mass motions in post-shock layers. Finally, our current understanding of the formation of the diffuse supernova neutrino background is highlighted and the perspectives for a detection of this relic signal that integrates the contributions from all past core-collapse supernovae in the Universe are analyzed.

EPJ Plus – Recent Highlights
EPJ Plus – Recent Highlights Epidermal growth factor promotes a mesenchymal over an amoeboid motility of MDA-MB-231 cells embedded within a 3D collagen matrix
Dongil T. Geum, Beum Jun Kim, Audrey E. Chang, Matthew S. Hall, and Mingming Wu
The micro-environment surrounding cancer cells is just as important as genes in regulating tumour progression. Scientists have therefore examined the biophysical and biochemical cues occurring in the vicinity of cancer cells. This represents a departure from the traditional measurement of secreted molecules, called biomarkers. The latest research in this field, recently published in EPJ Plus as a paper belonging to the Focus Point on the "Physics of Cancer", to be completed shortly found that the presence of a substance called Epidermal Growth Factor (EGF) promotes the motility of elongated mesenchymal tumour cells, which migrate depending on their adhesive properties by climbing along collagen fibres, in contrast to rounded tumour cells, which migrate in an adhesion-independent manner.
