Consideration of sex as a biological variable in diabetes research across twenty years

This study assesses the inclusion of biological sex in diabetes research over 20 years, finding less than 15% of papers used sex-based analysis and highlighting the need for improved consideration of sex as a variable.

Embracing imperfection: machine-assisted invertebrate classification in difficult datasets

This paper trains machine learning models to classify terrestrial invertebrates using morphometric data and contextual metadata, achieving 72.7% accuracy at the lowest taxonomic level.

Ocean acidification increases susceptibility to sub-zero air temperatures in ecosystem engineers (Mytilus sp.): a limit to poleward range shifts

This study shows that ocean acidification reduces freeze tolerance in Mytilus species, potentially limiting their poleward range shifts as temperatures rise.

Dityrosine cross-links are present in Alzheimer's disease-derived tau oligomers and paired helical filaments (PHF) which promotes the stability of PHF-core tau (297-391) in vitro.

This study shows dityrosine crosslinks are present in Alzheimer's disease tau oligomers and paired helical filaments, increasing their stability in vitro.

Proteostasis in ice: The role of heat shock proteins and ubiquitin in the freeze tolerance of the intertidal mussel, Mytilus trossulus

This study investigates freeze tolerance in the mussel Mytilus trossulus by comparing mortality, HSP70 expression, and ubiquitin levels after single versus repeated freeze-thaw cycles.

Population demography maintains biogeographic boundaries

The paper shows that populations near biogeographic transition zones have lower genetic diversity and effective population sizes, suggesting reduced adaptive capacity and maintaining biogeographic boundaries.

Crowd-sourced observations of a polyphagous moth reveal evidence of allochronic speciation varying along a latitudinal gradient

The paper uses crowd-sourced data to show that life history timing and color morph divergence in fall webworms increase with lower latitude, supporting allochronic speciation along a latitudinal gradient.

Molecular evidence of intertidal habitats selecting for repeated ice-binding protein evolution in invertebrates

The paper identifies a higher prevalence of ice-binding proteins in intertidal invertebrates compared to other habitats, with these proteins showing similarity to known antifreeze proteins from fish.

The benefits of herbivory outweigh the costs of bioerosion in a eutrophic coral community

This study shows that sea urchins benefit coral communities by reducing algal-sediment accumulation and maintaining coral growth, despite causing increased bioerosion in some species.

Plasticity of cold hardiness in the eastern spruce budworm, Choristoneura fumiferana

The paper examines cold hardiness plasticity and local adaptation in the eastern spruce budworm, finding no transgenerational plasticity but evidence of local adaptation affecting overwintering survival.

Transcriptional dynamics following freezing stress reveal selection for mechanisms of freeze tolerance at the poleward range margin in the cold water intertidal barnacle Semibalanus balanoides

This study compares transcriptomic responses to freezing stress in two populations of barnacles, finding distinct gene expression patterns and evidence of local adaptation to freezing at the poleward range margin.
