Quoting the title of the TNC2022 conference GARR hosted last June in Trieste, this issue focusses on navigating the unexplored. This is just what so many Italian scientists who left their mark in the history of science have been doing.

Boulevard and squares, streets and lecture halls were entitled to Galileo Galilei, Enrico Fermi and many others for their achievements, but also some of the more illustrious of the Italian science museums. This issue of the "Caffè Scientifico" section is dedicated to these extraordinary places, where past and future meet.

From Museo Galileo to Science Center Immaginario Scientifico in Trieste, from MUSE in Trento to CREF, the Enrico Fermi history of Physics museum, located in legendary via Panisperna, this issue explores the many innovative languages used to disseminate science over the network.

Withe the resources made available by the NPRR, recovery (also) stems from network evolutions: in this issue we illustrate the initiatives funded for this sector and their impact on the evolution of the national R&E Network infrastructure. And, speaking of brand-new GARR-T network, our readers can have a peek at where we are with its implementation..

Speaking of funding programmes that support new ideas, in the "Internazionale" section we talk about a first appraisal of Horizon Europe, and also of the GÉANT innovation programme, dedicated to speed up innovation in R&E networking and related services.

Building new tools is paramount, but sometimes you can also use what you already have in a totally new way: in the section dedicated to services, alonside the creation of new eduGAIN criptographic key we also tell how to follow the natural phenomena monitored by Italian Research institutions, from Mount Etna's eruptions to "acqua alta" in Venice, live on GARR TV.

In the section dedicated to cloud we will explore together the evolution of edge computing models in the field of research and discuss their impact on networking: in his interview, Patrizio Dazzi, Università di Pisa, talks about edge from the point of view of R&S, while Daniele Cesini and Davide Salomoni, INFN CNAF, focus on its applications to scientific computing.

In another interview, with Massimo Carboni, GARR CTO, we discuss how emerging computing models and issues also model the networks that support them, and introduce the "demilitarised science" paradigm.

To navigate the unexplored you need to share and innovate: in this issue we talk about some tools to do it: the Creative Commons licenses and how to use them to share research products, and to do so as openly as possible, as expected from the newly published National Plan for Open Science, and of new professionals like the research managers, who can help support these processes.

Training has also a crucial role to create tomorrow's innovators. In this issue we feature the success story of ITS Volta in Trieste , with its training programmes focussed on IoT and innovative communication technologies applied to life sciences, but also some thoughts by education expert Mario Pireddu (Università della Tuscia) on "platformisation" and its implication on didacticts. The same topic is explored by our training manager, Gabriella Paolini, in this issue's Ieri, oggi, domani.

Last, but not least, in this issue you'll find articles on hot cybersecurity topics, from the threaths posed by the widespread diffusion of IoT devices, to supply chain security, and the evolution of DDoS, plus news from the wider GARR community in #la ricerca comunica. With videos, interviews and much more.

Enjoy this issue!
