Eight Is Enough?: The Ethics Of The California Octuplets Case, Scott Paeth
Eight Is Enough?: The Ethics Of The California Octuplets Case, Scott Paeth
Scott R. Paeth
The recent California octuplets case raises a number of important issues that need to be addressed in the context of the increasingly widespread practice of in vitro fertilization. This paper explores some of those issues as looked at from the perspective of protestant theological ethics and public theology, examining the moral responsibilities of the various participants in the process, both before and after the octuplets’ birth, including the mother, her doctors, the health care bureaucracy, the wider society, and the media. Each of these participants failed in significant respects to consider the ethical implications of the births in this complicated …

Escaping from predators often demands that animals rapidly negotiate complex environments. The smallest animals attain relatively fast speeds with high frequency leg cycling, wing flapping or body undulations, but absolute speeds are slow compared to larger animals. Instead, small animals benefit from the advantages of enhanced maneuverability in part due to scaling. Here, we report a novel behavior in small, legged runners that may facilitate their escape by disappearance from predators. We video recorded cockroaches and geckos rapidly running up an incline toward a ledge, digitized their motion and created a simple model to generalize the behavior. Both species ran …
