Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
The Anatomical Record, EarlyView.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),

The Anatomical Record, EarlyView.Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.

Breeding Status of Ospreys in Egypt (Red Sea) from 2012 to 2018
Пернатые хищники и их охрана, 2018 A new series of Osprey surveys started in early June of 2012 and ended in July of 2018. The main goal was to survey the local resident breeding Ospreys. We also visited three wintering areas in Malaha, Aswan and Lake Nasser. We found breeding and nesting

The Anatomical Record, EarlyView.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.
