The Age of Cognitive Empires

open access: yesWorld Affairs, Volume 189, Issue 2, Summer 2026.
ABSTRACT Cognitive empires represent a new form of imperial power: influence exercised not through territory or coercion but through the structuring of cognition itself. AI‐enabled systems increasingly shape emotion and judgment from within, producing influence that scales rapidly, appears voluntary, and hardens into mass cognitive dependence.

Genetic Confirmations of Dwarf Lemurs Across Madagascar Highlights Complex Biogeographic Patterns 马达加斯加全境鼠狐猴的遗传确认揭示了复杂的生物地理模式

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.
Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...
