A gorilla dubbed "best stud muffin" after fathering eight little ones at the Cincinnati's Zoo has not fathered any in five years since being introduced to Demba at the Philadelphia Zoo. So zookeepers there have decided the couple are not working out.

In May, Chaka, a 380-pound silverback, will travel to Columbia, S.C., to the Riverbanks Zoo. The departure of 19-year-old Chaka is bittersweet to keepers because he is a link to the era before a Christmas Eve 1995 fire at the zoo that killed 23 primates, including Chaka's parents. Chaka would have likely died, too, if he hadn't been on a breeding loan program in Cincinnati.

Demba and Chaka were supposed to breed and start a new dynasty of apes, but Demba may have been, biologically speaking, damaged goods from early gorilla-hood. She was raised by humans and didn't meet another of her own species for years. She never seemed quite comfortable with her own kind. But keepers were betting on Chaka's past success.

Meeting features Tommy Thompson

Cincinnati today becomes the first of several cities to participate in a national series of town meetings about diabetes. Secretary of Health and Human Services Tommy Thompson will speak at 2 p.m. at the Hilton Cincinnati Netherland Plaza downtown as part of a project to develop a national action plan to fight diabetes. An estimated 18.2 million people - about 6.3 percent of the population - have diabetes, according to the American Diabetes Association.
