Fermi LAT: More than six years of insights and new puzzles
R. Rando and S. Buson
In August 2008, the Large-Area Telescope (LAT) on board the Fermi γ-ray Space Telescope started nominal operations. Porting reliable high-energy physics technology into space and building on the heritage of the CGRO-EGRET predecessor, expectations were high for a bountiful season of GeV astrophysics. Now, after more than six years of nearly continuous operation of the Fermi-LAT, its scientific output is reviewed, focusing in particular on the works by the Fermi-LAT Collaboration. Relevant issues and open questions in cosmology are also addressed.

Papers presented at the Conference
"Incontri di Fisica delle Alte Energie – IFAE 2014"
Gran Sasso Science Institute, L'Aquila, 9-11 April 2014
Guest Editors: R. Cerulli and F. Vissani
Sono già pubblicati online quasi tutti i contributi dell'edizione di IFAE 2014, che è il primo fascicolo de Il Nuovo Cimento - Colloquia and Communications in Physics a essere pubblicato secondo la modalità "full Open Access". Gli articoli sono pubblicati online singolarmente non appena pronti senza dover aspettare il completamento del fascicolo, e possono già essere citati. Vi invitiamo a prendere visione e a dare ampia diffusione a questa iniziativa della Società Italiana di Fisica!
EPJ A – Recent Highlights
Improved chiral nucleon-nucleon potential up to next-to-next-to-next-to-leading order
E. Epelbaum et al.
Chiral effective field theory provides a systematically improvable perturbative approach to deriving nuclear forces in harmony with the symmetries of Quantum Chromodynamics. Combined with modern few- and many-body methods, this framework represents a commonly accepted procedure for ab initio studies of nuclear structure and reactions.

EPJ E – Recent Highlights
Free energy of formation of small ice nuclei near the Widom line in simulations of supercooled water
Connor R. C. Buhariwalla, Richard K. Bowles, Ivan Saika-Voivod, Francesco Sciortino and Peter H. Poole
Water behaves in mysterious ways. Especially below zero, where it is dubbed supercooled water, before it turns into ice. Calculating the energy barrier that keeps liquid water below zero from immediately turning into ice provides the key to understanding its ability to be compressed as temperature drops.
