Agricultural research. Gloved hands placing cow stomach tissue between two halves of a glass parabiotic chamber. Chemicals can be added to one side to see if the stomach transports them to the other side. This will show if ingested chemicals will end up in the body. In this case, the experiment will determine whether toxic alkaloid chemicals, produced by the Neotyphodium coenophialum fungus, which commonly infects fescue grass, enters the bloodstream of livestock feeding on the grass.
