The article presents a study which investigates the feeding behaviour in the cassowary or Casuarius casuarius that exploits fallen fruits. The study uses plesiomorphic tetrapod pattern and calculates kinematics of movement of the elements during food transport. Result reveal that transported food follows a ballistic curve with energy passed on by head backward displacement, permitting it to reach pharynx. It adds that the mechanism could be viewed as a specialisation or an ancestral mechanism.

The article presents a study which defines a method used for evaluating the injury potential of less lethal projectiles on the thoracic region. The study uses accelerometers and pressure sensors to measure the skeletal dynamic deflection and the distribution of thoracic response in porcine models. Result shows that kinetic energy is not sufficient for the local skeletal response to the impact of two projectiles.
