Jumbo phages are active against extensively-drug-resistant eyedrop-associated Pseudomonas aeruginosa infections.

The paper identifies jumbo and non-jumbo phages effective against XDR Pseudomonas aeruginosa isolates causing eyedrop-associated infections.

Dual functioning by the PhoR sensor is a key determinant to Mycobacterium tuberculosis virulence

This study identifies PhoR as a dual-function sensor kinase/phosphatase in M. tuberculosis, revealing its role in virulence through pH and salt sensing and regulation of the PhoP regulon.

Bacterial metatranscriptomes in wastewater can differentiate virally infected human populations

The paper shows that bacterial metatranscriptomes in wastewater can distinguish SARS-CoV-2 infected from uninfected human populations without directly detecting viral transcripts.

Multi-omics profiling of Earth's biomes reveals patterns of diversity and co-occurrence in microbial and metabolite composition across environments

The paper performs a multi-omics meta-analysis of microbial and metabolite data from diverse environments, revealing patterns of diversity and co-occurrence across biomes.

Metagenomic characterization of soil microbial communities in the Luquillo experimental forest (Puerto Rico) and implications for nitrogen cycling

This study characterizes soil microbial communities in the Luquillo Experimental Forest using metagenomics, revealing differences in nitrogen cycling genes compared to temperate soils.
