US‐Japan Alliance: Emmeshing Bilateralism Into Broader Multilateralism
Asia &the Pacific Policy Studies, Volume 13, Issue 2, May 2026.ABSTRACT In the 21st Century, geopolitical confrontation between the Eurasian continental powers and the sea powers works to divide Asia. The US‐Japan alliance has transformed itself from Japanʼs asymmetrical security dependence of the Cold War period into a mutual and more integrated partnership today.

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
The Anatomical Record, Volume 309, Issue 5, Page 1299-1312, May 2026.Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),
