Misalignment between light and temperature cycles leads to disrupted circadian behavior and a substantially altered rhythmic transcriptome.

By producing one hundred SARS-CoV-2 phylogenetic trees for different geographical and time scales, the maximum likelihood-based phylodynamic method implemented here enabled to robustly describe SARS-CoV-2 geographic spread through France, Europe, and worldwide in 2020.

A policing system in Bacillus velezensis coordinated extracellular matrix production and autotoxin synthesis/self-immunity to penalize cheater-like nonproducers in biofilm community, which enhances the population stability and ecological fitness under stress conditions and in the rhizosphere.

Ancient animal Dicer used its helicase domain to couple the detection of foreign double-stranded RNA to efficient ATP hydrolysis and antiviral defense, but this function declined before the advent of deuterostomes and vertebrates.

Resistance genes that spread as a result of the use of an antimicrobial peptide (colistin) in agriculture (MCR) protect bacteria against key components of human and animal immune systems.

An Escherichia coli line lacking deoxyribonucleotide synthesis has been created and subjected to experimental evolution, revealing that endosymbionts and pathogens that lack ribonucleotide reduction avoid loss of deoxyribonucleotides to central metabolism by disruption of the salvage pathway.

Snake venom phosphodiesterase (svPDE), one of the critical venom components, is co-opted from the ancestral ENPP3 gene that makes membrane-anchored ENPP3 into secretory svPDE by using an alternative 5' exon.

Treating color patterns in a geometric morphometrics framework reveals rapid rates of color evolution that are explained by a combination of intrinsic organismal features (color variation among patches) and geography within a cosmopolitan radiation of birds.

The emergence and evolution of different phage-resistance strategies during coevolution between a phage-sensitive strain and a polylysogenic competitor depend on the amount of phage pressure, the fitness costs of resistance, and how these may change at different time scales.

Two novel, tightly linked, and rapidly evolving genes encoding small secreted proteins are necessary for female mosquitoes to protect their retained eggs during extended periods of drought.
