A cryo-electron microscopy model of the active human apoptosome illuminates how this "wheel of death" binds the protease procaspase-9 to initiate programmed cell death.

Autophagy is critical for the turnover of inflammatory signaling complexes containing RHIM-domain proteins.

Physical and chemical interactions with bacteria influence the life and death of Emiliania huxleyi, a bloom-forming micro-alga important in global biogeochemical cycles.

Specification and expansion during rib development is explained by Agent-Based Modeling while respecting the locality of decision-making that occurs as millions of cells coordinate their behavior to form and refine spatial pattern.

A lack of oxygen activates a pathway that causes the bacterial cell wall to break down, which, in turn, aids bacterial biofilm development.

Research in molecular ecology and evolution is increasingly utilizing the model plant Arabidopsis thaliana, placing a spotlight on its natural history.

A compendium of critical genomic numbers for viruses through the lenses of different viral classification systems.
