ALICE sees new sign of primordial plasma in proton collisions
The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions

Shape-shifting collisions probe secrets of early Universe
The first high-energy collisions between light nuclei at the Large Hadron Collider confirm the unusual “bowling-pin” shape of neon nuclei and offer up a new tool to study the extreme state of matter produced in the aftermath of the Big Bang

ALICE bags about twelve billion heavy-ion collisions
The whopping number of collisions recorded by ALICE during the recent five-week heavy-ion run of the LHC is 40 times greater than the total recorded by the experiment in its previous periods of heavy-ion data taking, from 2010 to 2018

Bikash Sinha (1945 – 2023)
Bikash Sinha(1945 – 2023) — Bikash Sinha, influential Indian scientist and pioneer in quark–gluon plasma and the early Universe, passed away on 11 August at the age of 78. As one of the ALICE experiment’s early visionaries and architects, his impact on heavy-ion physics is unmistakable. Bikash Sinha was born on 16 June 1945 in

Thick-skinned: Scientists determine the thickness of neutron “skin” in lead-208 nuclei
This is the first measurement of the neutron skin of lead-208 using exchanges predominantly involving gluons and it can provide insight into the structure of nuclei and neutron stars
