Skin Hyperpigmentation: An Under‐Recognized Dermatological Clue to Vitamin B12 Deficiency

Clinical Case Reports, Volume 14, Issue 5, May 2026.
Hyperpigmentation over the dorsal aspect of both hands, prominently involving the knuckles. ABSTRACT Cutaneous hyperpigmentation, an overlooked manifestation, can be an early sign of vitamin B12 deficiency. This case highlights symmetric pigmentation on the dorsum of hands and palms in a long‐term vegetarian.

3RAD‐Guided SNP Discovery for Species Identification and Conservation of the Medicinal Southern African Tree Genus Greyia Hook. & Harv.

Ecology and Evolution, Volume 16, Issue 5, May 2026.
A two‐phase SNP discovery and assay‐development strategy was used to resolve species boundaries within the tree genus Greyia, as overlapping phenotypes and distributions limit accurate identification. From 47,726 genome‐wide SNPs generated by 3RAD sequencing, a diagnostic 23‐SNP Type panel was developed and validated, successfully distinguishing G ...

Caste as a Social Kind

Journal of Applied Philosophy, Volume 43, Issue 2, Page 431-450, May 2026.
ABSTRACT Gender and race have received significant philosophical attention recently; they are the paradigm cases of social kinds in most philosophical accounts. I argue for the inclusion of caste as a social kind because it affects the lives of many people, and because it presents itself as an important test case for philosophers of social kinds.
