A beautiful and colossal human sculpture is one of the latest cultural treasures unearthed by an international team at the Tayinat Archaeological Project (TAP) excavation site in southeastern Turkey. A large semi-circular column base, ornately decorated on one side, was also discovered. Both pieces are from a monumental gate complex that provided access to the upper citadel of Kunulua, capital of the Neo-Hittite Kingdom of Patina (ca. 1000-738 BC).

Emotional problems in childhood are common. Approximately 8 to 22 percent of children suffer from anxiety, often combined with other conditions such as depression.
