... can identify the presence of a single toxin, or a limited number of closely related toxins. The ability to monitor the health of small groups of cells, however, makes it possible to detect the presence of unknown poisons as long as they affect cell metabolism.

Of course, the other drawback of term-based approaches is that they have to be assigned manually by database curators, and this is often not consistent between different curators," said Murphy....Study in Royal Society journal on sense of fairness in chimpanzees
