Venetian isolation hospital gives up secrets

Archaeologists are excited over the revelations discovered during the excavation of graves on Lazzaretto, an island in the lagoon of Venice where the city's sick were isolated. The intensive study has led to incredible discoveries involving disease, diet and genetics.

Among the findings: Venetian people were short, and they were well-nourished, with no cavities in their teeth. The island was first used during an outbreak of plague in the 14th century and was closed in the 17th century.
