Secondary metabolites (SMs) are essential across all life domains, yet those originating from the Archaea domain remain poorly understood. Here, the systematic genome mining and the pioneering heterologous expression of archaeal SMs have revealed the chemical landscape of archaeal lanthipeptides, showing both canonical and non‐canonical forms.

Taxonomy of Chemical Bondings: Opportunities and Challenges
The recent focus on supramolecular and nanosized systems produced a major increase in the types of observed noncovalent interactions and in the diversity of terms used to designate them. A hierarchical categorization (taxonomy) of terms used to designate electrophile···nucleophile interactions is proposed here.

Environment, epigenetics and neurodegeneration: Focus on nutrition in Alzheimer's disease [PDF]
Many different environmental factors (nutrients, pollutants, chemicals, physical activity, lifestyle, physical and mental stress) can modulate epigenetic markers in the developing and adult organism. Epigenetics, in turn, can cause and is associated with

Phospho‐ribosyl‐pyrophosphate synthetase 1 (PRPS1) deficiency is secondary to loss of function variants in PRPS1. This enzyme generates phospho‐ribosyl‐pyrophosphate (PRPP), which is utilized in the synthesis of purines, nicotinamide adenine dinucleotide

Evolutionary interplay between viruses and R‐loops
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.
