TL;DR: It is found that actual tRNAs have significantly more matches between the two halves than do random sequences that can form the tRNA structure, and the hypothesis that the modern tRNA cloverleaf arose from a single hairpin duplication prior to the divergence of modern t RNA specificities and the three domains of life is supported.

TL;DR: This study addresses the associations between architectural design and the microbial biogeography of households across a gradient of urbanization in South America and found urbanized spaces uniquely increase the content of human-associated microbes and decrease exposure to the environmental microbes with which humans have coevolved.

TL;DR: The findings indicate that for most practical purposes, the assumption that reference species are equally likely to be observed is untenable, and q2-clawback provides a straightforward alternative for samples from common environments.

TL;DR: The results suggest that M. pyrifera-dominated kelp forests harbor distinct microbial communities that vary temporally, and several kelp-specific taxa were highly similar to other bacteria known to either prevent the colonization of eukaryotic larvae or exhibit antibacterial activities.

TL;DR: Supporting the hypothesis that microbial symbiosis is important to dominance in the canopy, it is found that the abundance of gut bacteria is positively correlated with stable isotope proxies of herbivory among canopy-dwelling ants, but not among ground-d Dwelling ants.
