Navigating Transition Metal‐Dependent Cell Death: Mechanisms, Crosstalk, and Future Directions
Advanced Science, Volume 12, Issue 46, December 11, 2025.Transition metals trigger distinct regulated cell death pathways beyond traditional apoptosis. This review examines ferroptosis (iron‐catalyzed lipid peroxidation) and cuproptosis (copper‐induced mitochondrial proteotoxicity), while exploring hypothetical “cobaltosis” as a novel pathway.

Anaerobic Limonene Metabolism in a Methanogenic Enrichment Involves a Glycine Radical Enzyme
Environmental Microbiology, Volume 27, Issue 11, November 2025.A methanogenic enrichment culture on the natural monoterpene limonene is characterised by a novel glycine radical enzyme for anaerobic hydrocarbon activation, the presence of a microbial loop for necromass utilisation and the presence of a predator of Bacteria and Archaea. ABSTRACT Limonene is a natural monoterpene omnipresent in human environments. It
