Mortara Case (was an Italian cause célèbre that captured the attention of much of Europe and North America in the 1850s and 1860s. It concerned the Papal States' seizure of a six-year-old boy named Edgardo Mortara from his Jewish family in Bologna, on the basis of a former servant's testimony that she had administered an emergency baptism to the boy when he fell ill as an infant. Mortara grew up as a Catholic under the protection of Pope Pius IX, who refused his parents' desperate pleas for his return, and eventually became a priest. The domestic and international outrage against the pontifical state's actions may have contributed to its downfall amid the unification of Italy)

Quorum Sensing (is the ability to detect and to respond to cell population density by gene regulation. As one example, quorum sensing (QS) enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial. Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. In a similar fashion, some social insects use quorum sensing to determine where to nest. Quorum sensing may also be useful for cancer cell communications)
