Analysis of deer stone and khirigsuur complexes in Late Bronze Age Mongolia reveals complex ritual practices centered around horse sacrifices and caprine bone deposits. The study, conducted at Tsatsyn Ereg, found that peripheral mounds contained the remains of elderly male horses, suggesting a more nuanced mortuary ritual than simple in situ sacrifice. Circles of stones surrounding fireplaces were linked to purification rituals, with disproportionate representation of caprine teeth and feet indicating selective processing. The alignment of structures and horse orientations implied a symbolic connection to the rising sun, highlighting the communal and religious significance of these monuments.

Researchers have identified and described <em>Cyanocephalus veadeiroensis</em>, a striking new plant species from the Chapada dos Veadeiros region, Goiás, Brazil. This discovery, initially recognized on Facebook, highlights unique morphological traits such as densely imbricate leaves that obscure stems, leaf lengths exceeding internodes, nearly parallel secondary veins, and acuminate leaf apices. The species is distinct from similar taxa like <em>Cyanocephalus adpressus</em> and <em>C. lanatus</em>. The study provides comparative analysis, distribution insights, and ecological notes, contributing to the understanding of biodiversity in this UNESCO-recognized Cerrado Protected Area.

Researchers developed a monument-mapping method to efficiently detect and quantify weathering damage on historical buildings, focusing on the Music School of the University of Guanajuato, Mexico. This approach identified five key forms of stone decay—fractures, salts, oxides, scaling, and lichen—using digital image processing. The study also characterized less-known decorative stones used in 18th- and 19th-century structures, providing mineralogical and petrophysic insights. By mapping damage size and location on green sandstone, the method offers a rapid, qualitative, and quantitative assessment tool for conservation efforts at UNESCO World Heritage Sites like Guanajuato.

A growing global trend sees sites of war, genocide, and massacres being recognized as cultural heritage, a process known as 'heritagization.' This phenomenon, coupled with the rise of 'dark tourism'—where visitors seek out locations of mass suffering—is examined in a study focusing on the memorials of the 1994 genocide against the Tutsi in Rwanda. The research reveals how these sites, once symbols of atrocity, are now being framed as heritage destinations, drawing both academic and public interest. The study employs qualitative analysis to explore this shift, highlighting its implications for memory, tourism, and the preservation of traumatic histories.
