The methanogen core and pangenome: conservation and variability across biology’s growth temperature extremes
"Increased methanogenic growth temperature is associated with reduced genome size, and thermotolerant organisms...have larger core genome fractions, suggesting that genome size is governed by temperature rather than phylogeny. "

The methanogen core and pangenome: conservation and variability across biology’s growth temperature extremes
Abstract. Temperature is a key variable in biological processes. However, a complete understanding of biological temperature adaptation is lacking, in part becaProndzinsky, Paula (Oxford University Press)
A field-wide assessment of differential expression profiling by high-throughput sequencing reveals widespread bias
A large-scale examination of differential RNA expression study datasets submitted to the NCBI GEO repository from 2008-2020 reveals widespread bias, as assessed by the distribution of p values and estimated proportions of true null hypotheses.doi.org
Scaling of Protein Function Across the Tree of Life
"The abundance of functional categories in a given genome scales with genome size, suggesting that universal constraints shape category abundance. Here we look across the tree of life to understand how genome evolution may be related to functional scaling. "

Scaling of Protein Function Across the Tree of Life
Scaling laws are a powerful way to compare genomes because they put all organisms onto a single curve and reveal non-trivial generalities as genomes change in size.bioRxiv

Bacteriophages inhibit and evade cGAS-like immune function in bacteria
Bacteriophages antagonize cGAS-like bacterial immunity by sequestering immune signaling molecules and acquiring capsid gene mutations.Cell
This fascinating new #metagenomics research in mBio explores a potentially important and intriguing link between the presence and relative abundance of different functional guilds present in the human gut #microbiome (including short chain fatty acid biosynthesis and virulence functions) and disease severity and outcomes resulting from the virus. Clearly a subject for future extended studies to explore potential increases in severity due to infection and exacerbated or mitigated by differences in gut microbiomes.
