Nanogap Solid-State Single-Molecule Detection at Mars, Europa, and Microgravity Conditions

This paper develops a nanogap solid-state system for single-molecule detection under space-relevant conditions and validates its performance in microgravity and reduced gravity environments.

Translation as a Biosignature

This paper proposes that translation apparatuses, like ribosomes, could serve as biosignatures for detecting extant life beyond Earth and demonstrates machine learning's ability to classify biomolecules.

Solid-State Single-Molecule Sensing with the Electronic Life-detection Instrument for Enceladus/Europa (ELIE)

The paper introduces ELIE, a solid-state instrument for detecting amino acids and informational polymers to search for life on icy moons, demonstrating single-molecule detection of L-proline.

A general mechanism of air-borne hearing in Recent and early non-tympanate tetrapods

The paper investigates the mechanism of air-borne hearing in non-tympanic tetrapods, finding that low-frequency sound sensitivity aligns with a head translation model.

Freeze-thaw Cycles Enable a Prebiotically Plausible and Continuous Pathway from Nucleotide Activation to Nonenzymatic RNA Copying

This paper demonstrates that freeze-thaw cycles enable a continuous prebiotic pathway for nucleotide activation and nonenzymatic RNA copying in a single reaction mixture.

Microbial habitability of the early Mars lacustrine environment sustained by iron redox cycling

This study models microbial habitability of early Mars using Fe-redox cycling and water chemistry data from Gale crater, suggesting sustained microbial communities and implications for biosignature preservation.

A First-Order Design Requirement to Prevent Edema in Mechanical Counter-Pressure Space Suit Garments

The paper determines a first-order design requirement for mechanical counter-pressure space suits to prevent edema by analyzing pressure variations and their effects on capillary fluid dynamics.
