The head of the U.S. military says his country is holding exercises with South Korea to help control the situation there and make it more stable. They are not meant to add to the tension with North Korea.
Admiral Mike Mullen says South Korea will practice preventing another attack like the sinking of the Cheonan. Investigators have decided this was done by North Korea.
The Cheonan sank on March 26th. Forty-six South Korean sailors were killed.
Mullen says, "North Korea is predictable in one sense: that it is unpredictable . . ."
Specialist Kevin Pemberton is a U.S. soldier whose job is to act like the enemy.
Pemberton works at Fort Polk, Louisiana, where soldiers practice to fight in Afghanistan. There are 22 "villages" there, with people pretending to be Afghans. Pemberton blends in with them and tries to carry out "suicide bombings". The other soldiers don't always catch him.
A doctor in California has been sentenced to 30 months in prison. Xinming Fu was the last member of a group of 17 people guilty of health care fraud.
The group included six doctors. Members paid the owners of care homes to let them talk to people living there -- seniors and the mentally ill. Then they arranged respiratory (breathing) tests for them. The tests were not needed, not done the right way, or not done at all. But the group charged Medicare (a program which pays health costs for the elderly and others) for the tests.
Members got people to agree to the tests by offering them snacks and cigarettes. Sometimes, people were away in a hospital -- but the group still charged for a test at the care home.
