Proton Acceleration with Relativistic Electromagnetic Shock
Advanced Science, Volume 12, Issue 30, August 14, 2025.New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Brain and Behavior, Volume 15, Issue 8, August 2025.How do we accurately measure mind wandering? This review compares five methods: from self‐reports (prone to bias) to brain scans (precise but expensive). No single method captures all aspects, so we propose the MAMW framework—a unified approach combining strengths of each technique.

Human flaws and logical tools in engineering
The Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3512-3520, August 2025.Abstract This paper explores the limitations of human cognition, especially in engineering research, emphasizing the need for mathematical models and methods to guide decision‐making and theory validation. While human cognition excels in certain tasks, it is prone to biases that can distort our understanding.

Ecology and Evolution, Volume 15, Issue 8, August 2025.Dung beetles have important ecological and economical values; however, the molecular research of the taxonomic group is very limited. We sequenced mitochondrial genomes of four Scarabaeinae species, with sizes from 14,977 to 18,425 bp, and identified novel gene rearrangements.
