The paper discovers and engineers an orthogonal translation system using metagenomic data to expand the genetic code with non-canonical amino acids.

The paper analyzes microbial autotrophy in soils using metagenomic and metatranscriptomic data, finding widespread RuBisCO genes and prevalence in deep, saturated soils.

The paper identifies and characterizes Borgs and mini-Borgs in Methanoperedens archaea, revealing their evolutionary origins and genomic relationships.

This study examines soil viral communities in Mediterranean grasslands, finding that spatial factors dominate over temporal variation in shaping viral community structure.

The paper identifies divergent ribosomal RNA sequences in the PTC of archaea and determines their structure, revealing sequence variation and a novel hibernation factor.

The paper identifies circular 23S rRNA in archaeal ribosomes, showing they are more abundant than linear forms and confirms their structure through sequencing and modeling.

The paper investigates how microbial activity in grassland soils varies with depth and water availability, identifying active predatory bacteria and episymbionts in different soil layers.
