Assessing the Climate and Habitability of Tidally Locked Rocky Exoplanets

Tidally locked exoplanets orbiting M dwarf stars are prime targets in the search for habitable worlds, yet their complex climate dynamics challenge conventional models of habitability. We homogeneously estimated the liquid–water habitability of exoplanets with the highest up-to-d...

Adaptive thermogenesis and fermentation as survival strategies of vegetative cells of Bacillus subtilis under simulated Martian stressors

<title>Abstract</title> Microbial responses to Mars‑analog environments are key to understanding the limits of life and improving life‑detection strategies. Here, we investigated the survival and physiological adaptation of <italic>Bacillus subtilis</italic> exposed for five sols...

Synthesis of mineral-organic hybrid materials under dynamic prebiotic conditions

Abstract The increasing of molecular complexity must be understood as a planetary phenomenon where prebiotic chemistry and geological settings converge. In this scene, HCN chemistry may have played a crucial role. In this study, we demonstrate that alkaline water aerosols, cyanid...

Inventories of Rich Carbon-Chain Chemistry in Prestellar and Starless Cores in the Perseus Molecular Cloud

Abstract Carbon-chain molecules serve as an important reservoir of reactive organic matter that will eventually be incorporated into protoplanetary disks, planets, and cometary material. Prestellar and starless cores are composed of cold (~ 10 K) and dense (~ 105 cm−3) clumps of...

Characterization and treatment of polymicrobial biofilms in prosthetic joint infections

Abstract Prosthetic joint infections are complex and associated with high economic and social costs. Polymicrobial cases remain poorly understood, particularly regarding bacterial interactions and antibiotic response within mixed-species biofilms. We introduce two approaches for...
