Naturalistic animal behavior exhibits a complex organization in the temporal domain, whose variability stems from hierarchical, contextual, and stochastic sources and can be naturally explained in terms of metastable attractor models.
When exposed to high-dose ionizing radiation, tardigrades undergo extensive DNA damage, like humans, but cope by stimulating expression of DNA repair proteins and of TDR1, a novel tardigrade-specific DNA-binding protein.
Mice exploring a labyrinth freely for the first time learn a complex action sequence after a handful of rewards, exhibiting a learning rate 1000-fold higher than in commonly-used paradigms.

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.
After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

Stimulation of cells with a mitochondria-depolarizing mitogen reveals a requirement for UBQLN1 expression in maintaining protein synthesis levels during cell cycle entry.
LPS pre-exposure is tissue protective during a subsequent lethal E. coli peritonitis by long-term modulation the bone marrow B-cell and neutrophil pool which affects neutrophil tissue damaging properties and therapeutic activation of Cxcr4 promotes tissue damage control during sepsis.
