Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
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),

Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Fruit and vegetable peels, rich in nutrients such as fiber and phenolic compounds, can boost livestock productivity, enhancing milk, meat, and draught power. Their use as animal feed reduces organic waste, cuts greenhouse gas emissions, and decreases dependence on grain‐based feeds, offering a sustainable solution with significant nutritional and ...
