Prebiotic magnetite enables chirality-magnetic surface feedback

The emergence of biomolecular homochirality requires both an initial symmetry-breaking event and a mechanism to amplify and preserve a chiral imbalance. Magnetic minerals have been shown to function as chiral agents through the chiral-induced spin selectivity (CISS) effect and ma...

High flow capacity and low viscosity of the Séítah formation, at Jezero Crater, Mars

Abstract The unexpected discovery of olivine cumulate at the Séítah Formation within Jezero Crater was one of the most compelling findings of the Mars2020 Perseverance rover mission thus far. Compared to Earth, Mars is a basaltic world and differences in gravity, atmosphere and...
