Archaeometallurgical analysis of Arslantepe Mound (VI B2) reveals that Early Bronze Age copper smelting was conducted using portable crucibles with a sophisticated air supply system, challenging the prevailing model of deliberate fluxing. Lead isotope and petrology studies of slags trace copper sources across East Anatolia, including regions along the Black Sea coast (Artvin/Murgul, Trabzon) and Upper Mesopotamia (Ergani Maden), expanding our understanding of the Kura-Araxes cultural network's trade routes during this period. The research also demonstrates that slags from Arslantepe, Çayönü Tepesi, and Nevali Çori formed through partial eutectic smelting processes, ruling out the non-liquation of refractory materials.

Newly opened archives reveal the sophisticated operations of the Qing dynasty's Imperial Household Agency (Neiwufu), showcasing its role as a vast, machine-like institution that mobilized people, objects, and nature across an expanding empire. The agency, headquartered in Beijing but with operations stretching throughout China, managed the acquisition, processing, and transformation of raw materials—such as wood, jade, porcelain, and fur—to produce luxurious items for the imperial family, including furniture, textiles, ceramics, and even live elephants. It relied on a complex network of skilled laborers, artisans, and technical expertise from diverse ethnic groups, including Tibetans, Mongols, and Europeans. The study highlights the agency's organizational innovations, such as sophisticated record-keeping, audits, and surveillance systems, which paralleled broader societal processes. While the 'palace machine' analogy emphasizes its systematic nature, the research also underscores the flexibility and adaptability of its operations, challenging rigid notions of rationality.

In wild Guinea baboons, male-male social bonding does not directly translate to reproductive success. Contrary to expectations, males that spent less time socializing with other males were associated with more females and sired more offspring, while strongly bonded males provided coalitionary support during conflicts but did not gain reproductive advantages. This suggests a nuanced relationship between social investment and reproduction, where males adjust their social behavior based on life-history stages. The study analyzed behavioral and paternity data from 30 males over four years in Niokolo-Koba National Park, Senegal, highlighting the complexity of male-male bonding dynamics in this tolerant multi-level society.

Research reveals that the overdominance of Maling bamboo (<em>Yushania maling</em>) in Khangchendzonga National Park, part of the Himalayan Biodiversity Hotspot, significantly alters forest structure and composition. A study across 69 plots (2400–3400 m asl) found that bamboo-dominated areas exhibit markedly lower species richness, density, and seedling density in shrub and herb layers compared to non-bamboo plots. Generalized Additive Models confirmed a strong negative correlation between bamboo density and species diversity (<em>p</em> < 0.0001). These findings underscore the ecological threat posed by <em>Y. maling</em>, necessitating its managed removal for both conservation and economic benefits, such as handicraft production. The study also calls for long-term research to assess impacts on soil dynamics.
