Arsenic Uptake From Artisanal Gold Mining Wastewater Using Magnetized and Functionalized 2‐Mercaptobenzothiazole Nanosilica: Characterization, Taguchi Optimization, Statistical Analysis and Adsorbent Reusability

Engineering Reports, Volume 8, Issue 8, August 2026.
A local adsorbent, synthesized via magnetization and functionalization of nanosilica from rice husk, was applied to eliminate As5+ from gold mining wastewater sample. Adsorbent was characterized using BET, FTIR, SEM and XRD and was proved to be effective and suitable for As5+ removal from gold mining wastewater.

Assessing the Conservation Status, Drivers of Threat and Available Occurrence Records of Sub‐Saharan African Freshwater Molluscs: Gaps and Patterns

African Journal of Ecology, Volume 64, Issue 6, August 2026.
ABSTRACT Freshwater molluscs are key bioindicators of ecosystem health, yet their conservation status and data coverage in sub‐Saharan Africa remain poorly understood. Mollusca is the third most evaluated phylum on the IUCN Red List in Africa, with 1394 species assessed (656 freshwater), of which 39.6% are Least Concern and 12% Critically Endangered ...

Of cables and threads

American Ethnologist, Volume 53, Issue 3, Page 283-295, August 2026.
Abstract Over the past two decades, gondola lifts have become central to interventions in urban Latin America's auto‐constructed peripheries. As cable car urbanism reshapes the city's edge, it raises fundamental questions about the notion of the “urban fabric” as a sociomaterial practice, an epistemology, and a site of politics.

Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis

Review of Development Economics, Volume 30, Issue 3, Page 1957-1972, August 2026.
ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.
