This study investigates N2O formation and consumption in thawing permafrost using microcosms, finding that N2O formation exceeds consumption, likely driven by non-denitrifying bacteria.

The paper finds that thermophilic traits in permafrost microbes correlate with slow growth in low-energy environments, suggesting these traits are an adaptation to persistent cold rather than phylogenetic constraints.

BONCAT-Live isolates and cultivates active bacteria from environmental samples in response to specific stimuli, enabling study of their metabolic and adaptive responses.

This study identifies genetic traits enabling Promethearchaeota to persist in marine sediments frozen for over 100 kyr, showing their survival through DNA repair and stability.

The paper identifies host-microbiome interactions using systems genetics in mice, revealing mechanisms of microbial involvement in disease.
