Kharkiv, Ukraine, one of Cincinnati's sister cities, and a city known for the manufacturing of machinery and electronics, is trying to become more energy efficient.

A delegation of government workers traveled to the U.S. to learn how Greater Cincinnati recycles, uses solar energy, filters water, and generates heat and electricity.

We are accustomed to odd weather in the Tri-state, but this summer has been particularly unusual: heavy rains and unseasonably low temperatures followed by days of intense, dry heat, followed by more rain and cooler days.

The Cincinnati Zoo is in the midst of a massive project to make hippos feel welcome and give them a clean place to live.

The clean part sounds easier than it actually is because the dirty little secret about hippopotamuses is they poop a lot. Two of them defecate nearly 1,000 pounds a day. In essence Mark Fisher, vice president of the zoo's facilities, says he has to build a massive toilet that is nice and clean so visitors can view the hippos in an underwater tank.
