Co-occurrence networks reveal more complexity than community composition in resistance and resilience of microbial communities
Fungal communities showed greater resistance but less resilience to drought than bacterial communities, though fungi were unexpectedly resilient in the first week of rewetting. Drought increased positive correlations among microbial taxa and networks based on positive correlations, but decreased overall network complexity suggesting a potential role for microbial communities in plant drought response.

Nutrient supply controls the linkage between species abundance and ecological interactions in marine bacterial communities
Nutrient availability drives a shift in the ribosomal RNA gene operon copy number in marine bacteria, with nutrient-rich environments favoring high copy numbers and vice versa. Ecological interactions shift from cooperative to competitive as nutrient levels increase, suggesting a "hunger games" scenario where microbes adapt their strategies based on resource availability.

Specialized metabolic functions of keystone taxa sustain soil microbiome stability
Soil bacterial communities with greater phylogenetic diversity tend to be more stable under varying pH conditions. Keystone functions, particularly "nitrogen metabolism" and "phosphonate and phosphinate metabolism," are performed by specialized bacterial taxa like *Nitrospira* and *Gemmatimonas*, and appear essential for maintaining stability.

Bioengineered bacteria-derived outer membrane vesicles as a versatile antigen display platform for tumor vaccination via Plug-and-Display technology
This study presents a new tumor vaccine platform using bioengineered bacterial outer membrane vesicles (OMVs). By displaying tumor antigens on the OMV surface via a "Plug-and-Display" system, the platform elicited robust anti-tumor immune responses in mice, suggesting its potential for personalized cancer vaccines.

Genome-resolved metagenomics suggests a mutualistic relationship between Mycoplasma and salmonid hosts
The study found a dominance of Mycoplasma in the gut microbiomes of three salmonid species, suggesting two novel candidate species. Genomic analyses suggests this Mycoplasma has adapted to the intestinal environment of salmonids and may provide benefits to the host including B vitamin biosynthesis and ammonia detoxification.

Phylogenomics of expanding uncultured environmental Tenericutes provides insights into their pathogenicity and evolutionary relationship with Bacilli
The study discovered several novel Tenericutes lineages in various environments, including the human gut. Phylogenomic analysis placed these lineages close to other Bacilli groups, blurring the lines between Tenericutes and Bacilli. The two main human gut lineages, RF39 and RFN20, were predicted to be hydrogen producers and may play a role in gut homeostasis.
