Different developmental stages of a venomous animal (e.g. Nematostella vectensis) with a complex life cycle produce vastly different venoms that can serve in different antagonistic interactions with other species.
Early life adversity led to hyper-innervation from the basolateral amygdala to the prefrontal cortex earlier in females than males and disrupted maturation of functional connectivity, which predicted anxiety-like outcomes.
Mice exposed to complex early adversity show similar diffusion MRI changes to those reported in humans and sex-specific changes in connectivity that differentially affect contextual deficits in males and females.
Resetting a young gut microbiota in middle-aged individuals extends life span and slows aging in the naturally short-lived turquoise killifish, a new vertebrate model organism to study how the microbiota affects the aging process.
TALE homeodomain transcription factors have been independently recruited to regulate gametophyte to sporophyte transitions in two complex multicellular eukaryotic supergroups, land plants in Archaeplastida and brown algae in Chromalveolata.
