Henrique Teotónio and colleagues report a comprehensive study of the molecular population genetics of adaptation and reverse evolution in Drosophila. They conclude that adaptive reverse evolution in this context tends to occur from the sorting and recombination of standing genetic variation at multiple loci, rather than from the fixation of new mutations.

The Omicron variant evades vaccine-induced neutralization but also fails to form syncytia, shows reduced replication in human lung cells and preferentially uses a TMPRSS2-independent cell entry pathway, which may contribute to enhanced replication in cells of the upper airway. Altered fusion and cell entry characteristics are linked to distinct regions of the Omicron spike protein.

Transcriptomic and proteomic profiling of blood samples from individuals with COVID-19 reveals immune cell and hematopoietic progenitor cell alterations that are differentially associated with disease severity.

Invasive Spartina grasses accumulate high levels of intracellular dimethylsulfoniopropionate (DMSP). Here, the authors report the isolation and characterization of the genes involved in DMSP biosynthesis and show that administration of DMSP by root uptake or overexpression of the DMSP biosynthesis genes results in salinity and drought tolerance in Arabidopsis.

Identifying a complex panel of bias dimensions to be evaluated, a framework is proposed to assess how prone large language models are to biased reasoning, with possible consequences on equity-related harms, and is applied to a large-scale and diverse user survey on Med-PaLM 2.

They identify important factors that contributed to within university transmission and onward spread into the wider community.

The evolution of the Amazon forest is tightly coupled to its terrestrial water balance. Here, the authors show that forest biomass changes in the Amazon are a driver of the spatiotemporal variation of evapotranspiration, and such changes could have a larger impact on water availability in the dry regions (southern, eastern) of the Amazon.

Coding variants in peptidylglycine α-amidating monooxygenase (PAM) associated with type 2 diabetes risk negatively impact overall PAM activity via defects in expression and catalytic function, resulting in reduced insulin content and altered dynamics of insulin secretion.

Mechanistic inference following GWAS is hampered by the lack of tissue-specific transcriptomic resources.
