Scientists have built a robotic stingray made of heart muscle cells from a rat, a skeleton of gold, plastic fins, and light-activated algae proteins. The tiny, 16-millimeter-long robots take about a week to make and can be controlled with light. Anthony and Jeff discuss the nature of abominations, and try to decide if this qualifies as one.
