Mineral-Mediated Oligoribonucleotide Condensation: Broadening the Scope of Prebiotic Possibilities on the Early Earth

open access: yesLife, 2023
The origin of life on earth requires the synthesis of protobiopolymers in realistic geologic environments along strictly abiotic pathways that rely on inorganic phases (such as minerals) instead of cellular machinery to promote condensation.

A sustainable culture of tardigrades (Hypsibius dujardini) for astrobiological laboratory activities [PDF]

open access: yesEPJ Web of Conferences, 2019
Tardigrades are microscopic organisms that have gained importance in astrobiology in recent years. They have extreme survival ability and can enter into a state of latency for several years called cryptobiosis.
