When the Soviet Union splintered two decades ago, one of the biggest U.S. worries was how to ensure that the vast Soviet arsenal of nuclear weapons was kept secure.
The American response was the Cooperative Threat Reduction program of 1992. The U.S. provided money and expertise to lock down and track weapons of mass destruction and make sure they stayed out of the hands of rogue regimes or terrorists.
The program has been hailed as a great success, with thousands of Soviet nuclear weapons dismantled over the years.
For nearly a decade, scientists and Northwest tribes in Washington state fought bitterly over whether to bury or study the 9,500-year-old bones known as Kennewick Man. Scientists won the battle, and now, after years of careful examination, they're releasing some of their findings.

The names Columbine and Virginia Tech have both become tragic shorthand for school shootings in America. In the wake of those shootings, schools have developed a fairly typical lockdown procedure when there's a threat: sound the alarm, call police, lock doors and stay put.
The standard school-lockdown plan is intended to minimize chaos so police arriving on the scene don't shoot the wrong people. Students practice following directions, getting into classrooms and essentially, waiting.
