A new CO carbonaceous chondrite from Acfer, Algeria
Many small fragments, totally weighing 118 g were found in the Acfer area by an Italian dealer. Chondrules size and types (predominance of granular olivine type), occurrence of twinned clinoenstatite and absence of plagioclase suggested a classification as CO carbonaceous chondrite

Textural and minerochemical features of NWA 1807 and 2180, two new CV3 chondrites from northwest Africa
A textural and minerochemical study has been performed on NWA 1807 and 2180 chondrites in order to determine sizes and typologies of chondrules, relative abundances of mineral phases, compositions of main phases and bulk oxygen isotope composition
COVID-19: The wrong target for healthcare liability claims
Regrettably, after a first moment of appreciation and praise of the citizens for healthcare personnel facing COVID 19 pandemia, numerous episodes of actions taken against them on the issue of their legal liability followed. Impelling is to start an argumentation on this problem that aims to establish a shared conduct in dealing with them. The authors propose a basis for discussion on which to begin a constructive debate
