The cluster structure of the neutron-rich isotope Be has been probed via the () reaction. The triple differential cross-section was extracted and compared to distorted-wave impulse approximation reaction calculations performed in a microscopic framework using the Tohsaki-Horiuchi-Schuck-Rpke wave function and the wave function deduced from Antisymmetrized Molecular Dynamics calculations. The remarkable agreement between calculated and measured cross-sections in both shape and magnitude validates the description of the Be ground-state as a rather compact nuclear molecule.

Crystal structure, thermodynamic properties, and adiabatic demagnetization refrigeration (ADR) effect in the spin-1/2 triangular antiferromagnet KBaGd(BO) are reported. With the average nearest-neighbor exchange coupling of 44 mK, this compound shows magnetic order below = 263 mK in zero field. The ADR tests reach the temperature of = 122 mK, more than twice lower than , along with the entropy storage capacity of 192 mJ K cm and the hold time of more than 8 h in the PPMS setup, both significantly improved compared to the spin- Yb analog. We argue that KBaGd(BO) shows a balanced interplay of exchange and dipolar couplings that together with structural randomness and geometrical frustration shift to well below the ordering temperature , therefore facilitating the cooling.

The MMX InfraRed Spectrometer (MIRS) is an imaging spectrometer on board of MMX JAXA mission. MIRS is built at LESIA-Paris Observatory in collaboration with four other French laboratories, collaboration and financial support of CNES and close collaboration with JAXA and MELCO. The instrument is designed to fully accomplish MMX's scientific and measurement objectives. MIRS will remotely provide near-infrared spectral maps of Phobos and Deimos containing compositional diagnostic spectral features that will be used to analyze the surface composition and to support the sampling site selection. MIRS will also study Mars atmosphere, in particular to spatial and temporal changes such as clouds, dust and water vapor.
