The evolution of a butterfly mimetic phenotype is driven by modular cis-regulstory switches controlling a ‘hotspot’ gene.

Sex differences in the age-related decline of blood-brain barrier function vary across brain regions, with a more pronounced decrease observed in males beginning in the early 60s.

Restoring locomotion after complete spinal cord injury does not require locomotor training, only the return of sufficient excitability within neurons of the spinal cord.

Viral dynamic modeling reveals the relationship between SARS-CoV-2 viral load and infectiousness and allows to anticipate the effects of variants of concern and of vaccination on transmission.

Mutations that directly benefit both self and cooperative partner can readily evolve to promote cooperation.

Prokaryotic TRADD-N and Death-like adaptor domains in diverse predicted apoptosis and immune systems from multicellular prokaryotes and metazoans indicate the common origin of key apoptosis mechanisms required for the stabilization of multicellularity.

Exploring tissue-specific regulation of gene expression with human-chimpanzee hybrid cells helps us understand how life evolves and what makes us human.

The Trrap-HAT-Sp1 axis operates a conserved transcriptional program to control proper microtubule dynamics in brain homeostasis and prevents neurodegeneration.

The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.
