The adaptation of Arabidopsis plants to the local environment is linked to DNA methylation.

Viruses drive adaptation at the scale of the whole proteome and not only in antiviral proteins in mammalian hosts.

Whole genome sequencing of 19 populations of Atlantic and Baltic herring reveals hundreds of individual loci underlying adaptation to a low salinity niche or timing of reproduction.

Spike frequency adaptation provides spiking neural networks with long short-term memory.

Parallel changes in organismal evolution can be observed even with disparate genomic changes due to similarity in functional outcomes, such as changes in molecular phenotypes like gene expression patterns.

Cell culture adaptation of SARS-CoV-2 is prevented on human airway cells with an active serine protease-mediated entry pathway, allowing the production of genetically stable virus stocks for laboratory experiments.

Adaptation to climate in sunflowers is highly polygenic, but still involves significant repeatability with many of the same genes being used by multiple species.

Within 100 generations after an environmental shift in an evolution experiment, rapid sex-specific adaptation occurred, which is potentially facilitated by selection on standing variation in sex-specific genetic architecture.

Stochastic tuning of gene expression could be a common mechanism through which eukaryotic cells adapt to challenging external environments, potentially including survival of infectious organisms within the host and adaptation of cancer cells to chemotherapy.

A large-scale analysis of Staphylococcus aureus within-host evolution based on a comprehensive catalogue of bacterial genetic variation reveals an excess of genome degradation signatures in infecting strains and new genetic loci of clinically relevant adaptation.
