Discovery and ecogenomic context of a global Caldiserica-related phylum active in thawing permafrost, Candidatus Cryosericota phylum nov., Ca. Cryosericia class nov., Ca. Cryosericales ord. nov., Ca. Cryosericaceae fam. nov., comprising the four species Cryosericum septentrionale gen. nov. sp. nov., Ca. C. hinesii sp. nov., Ca. C. odellii sp. nov., Ca. C. terrychapinii sp. nov.

TLDR
These findings establish the SMCs as four novel phenotypically and ecologically distinct species within a single novel genus, distinct from C. exile clade at the phylum level, and part of a novel cold-habitat phylum for an understudied, globally-distributed superphylum encompassing the Caldiserica.

Multidomain ribosomal protein trees and the planctobacterial origin of neomura (eukaryotes, archaebacteria).

TL;DR: Unique presence of key pre-neomuran characters favours Planctobacteria only as ancestral to neomura, which apparently arose by coevolutionary repercussions (explained here in detail, including RP replacement) of simultaneous outer membrane and murein loss.

Microbiome assembly in thawing permafrost and its feedbacks to climate

TL;DR: In this paper , the authors propose Assembly Theory to better understand thaw-mediated microbial community changes and the implications for community function and climate feedbacks, and propose that the contribution of stochastic and deterministic processes to post-thaw microbiome assembly depends on the characteristics of the thaw disturbance.

Evidence for non-methanogenic metabolisms in globally distributed archaeal clades basal to the Methanomassiliicoccales.

TL;DR: Comparative genomic analysis of 12 Thermoplasmata metagenome-assembled genomes basal to the Methanomassiliicoccales shows that these microorganisms do not encode the genes required for methanogenesis, and suggests that meethanogenesis was laterally acquired by an ancestor of the Methaplasmatota.

Evidence for non-methanogenic metabolisms in globally distributed archaeal clades basal to the Methanomassiliicoccales

TL;DR: Through comparative genomic analysis of 12 Thermoplasmata metagenome-assembled genomes, it is shown that these microorganisms do not encode the genes required for methanogenesis, which suggests that this metabolism may have been laterally acquired by an ancestor of the order Methanomassiliicoccales.

The IsoGenie database: an interdisciplinary data management solution for ecosystems biology and environmental research

TL;DR: The IsoGenieDB is a public and private data infrastructure designed to store and query data generated by the Iso Genie Project, a ~10 year DOE-funded project focused on discovering ecosystem climate feedbacks in a thawing permafrost landscape, and is being expanded to cover the NASA-funded A2A project.

Basic Local Alignment Search Tool

TL;DR: A new approach to rapid sequence comparison, basic local alignment search tool (BLAST), directly approximates alignments that optimize a measure of local similarity, the maximal segment pair (MSP) score.

The Sequence Alignment/Map format and SAMtools

TL;DR: SAMtools as discussed by the authors implements various utilities for post-processing alignments in the SAM format, such as indexing, variant caller and alignment viewer, and thus provides universal tools for processing read alignments.

MAFFT Multiple Sequence Alignment Software Version 7: Improvements in Performance and Usability

TL;DR: This version of MAFFT has several new features, including options for adding unaligned sequences into an existing alignment, adjustment of direction in nucleotide alignment, constrained alignment and parallel processing, which were implemented after the previous major update.

RAxML version 8: a tool for phylogenetic analysis and post-analysis of large phylogenies.

TL;DR: This work presents some of the most notable new features and extensions of RAxML, such as a substantial extension of substitution models and supported data types, the introduction of SSE3, AVX and AVX2 vector intrinsics, techniques for reducing the memory requirements of the code and a plethora of operations for conducting post-analyses on sets of trees.
