Social object play between captive bottlenose and Risso's dolphins
<div><p>Many animal species engage in social object play with movable objects. Two bottlenose dolphins (<i>Tursiops truncatus</i>) and one Risso’s dolphin (<i>Grampus griseus</i>) owned by the Kujukushima Aquarium, Japan, occasionally shared and played with an object. Herein, we report social object play between two dolphins exchanging a ball in water. Just before delivery of the ball, one dolphin made an action to request the ball from the dolphin that possessed the ball. This request behavior is also discussed in this report. This study is the first to report two different cetacean species engaging in social object play with one object.</p></div
Ball exchange between a bottlenose dolphin (Niha) and a Risso’s dolphin (Lily).
<p>Lily released the ball from her mouth and Niha caught it.</p
An example of a bout of social object play.
<p>The vertical axis indicates the individual, and the horizontal axis indicates time. The hatched bar is the time of possession of the ball. The arrow indicates the destination of the ball. In this figure, Nami (bottlenose dolphin) possesses the ball by herself, whereas Niha (bottlenose dolphin) and Lily (Risso’s dolphin) share the ball.</p

Generality Assessment of a Model Considering Heterogeneous Cancer Cells for Predicting Tumor Control Probability for Stereotactic Body Radiation Therapy Against Non-Small Cell Lung Cancer
The generality of a model for predicting tumor control probability from in vitro clonogenic survival considering of cancer stem-like cells, the so-called integrated microdosimetric-kinetic model, is presented by comparing the model to public data on stereotactic body radiation therapy for non-small cell lung cancer cells
