Weekend All Things Considered

The Department of Homeland Security is examining its policy on deadly force along the U.S.-Mexico border. In less than two years, U.S. Border Patrol agents have killed 18 Mexican citizens there — including eight people who were throwing rocks.

Thousands of protesters flooded into the streets of Egypt on Friday — some in support of President Mohammed Morsi, others condemning what they called a vast power grab by the president that puts Egypt on the path to one-man rule.

It's a scene that's become wearily repetitive in the eastern part of the Democratic Republic of Congo: An uprising drives out poorly trained government troops, creating havoc and sending large numbers of refugees fleeing for their lives.

This time the rebel group is M23, or March 23. Their revolt began this spring, and earlier this week they took Goma, an important town on the country's eastern border, just across Lake Kivu from Rwanda. The rebels then proceeded to take the next town over, Sake.

A biologist who has been watching a dozen bottles of bacteria evolve for nearly a quarter of a century is hoping he can find someone to keep his lab experiment going long after he dies.

Meanwhile, just by coincidence, a botanist who works across campus is carefully tending an experiment that started before he was born, all the way back in 1879.

These two researchers, both at Michigan State University in East Lansing, represent different sides of an unusual phenomenon in science: experiments that outlive the people who started them.

We're going to ask her for some ideas on what do to with the leftovers. Hey there, Katie.
