L’alfa-sinucleina stimola le cellule staminali neurali

Roberto Coccurello, ricercatore nel nostro Istituto, ha collaborato ad uno studio che ha identificato il ruolo anti-invecchiamento neurale e di mantenimento della produzione di neuroni svolto in vivo da questa molecola. I risultati sono pubblicati su Frontiers in Cell and Developmental Biology.

In questo breve articolo divulgativo ci spiega il suo contributo.

Il cervello dei mammiferi continua a generare neuroni per tutta la vita, a partire da cellule staminali neurali, in due zone specifiche dette nicchie neurogeniche: il giro dentato dell’ippocampo e la zona subventricolare.

The Marvelous Physics of Swarming Midges – ISC research covered by The New York Times

On October 1st The New York times covers our research on swarms. The article begins like this:

On early autumn afternoons across the temperate world, the midges are now gathering to swarm: clouds of tiny flies, wings lit by the sun like so many sparks, swirling in patterns too quick and complicated for the eye to follow but leaving a mental afterimage of order.

QUANCOM project launched!

ISC researchers, C. Conti, L. Pilozzi and V. Brosco, participate in the new PON project QUANCOM.

Security technologies in both the network transmission layers and in the application layers are becoming more and more complex and sophisticated but, nevertheless these efforts, they are not completely immune to attacks. In fact, even the computing power (parallel and distributed thanks to the network resource) is increasing and available to organizations that, for various purposes, have interests in appropriating of sensitive data.

Seminar by Paola Verrucchi, Monday April 19 at 3 pm

There is only one time

We draw a picture of physical systems that allows us to recognize what “time” is by requiring consistency with the way that time enters the fundamental laws of Physics. Elements of the picture are two non-interacting and yet entangled quantum systems, one of which acting as a clock. In this setting, employing the Page and Wootters mechanism with tools from large-N quantum approaches, we show that there is not a “quantum time”, possibly opposed to a “classical” one; there is only one time, and it is a manifestation of entanglement.… Read the rest
