Richard Lenski examines the growth of bacteria on a plate on Jan. 12. He began an evolution experiment in 1988 with 12 identical flasks of bacteria to see if the populations would change over time in the same way.
Missy Mazzoli, a 32-year-old composer from Brooklyn, says she never wanted to write an opera until she read the journals of Isabelle Eberhardt, a Swiss adventurer from the turn of the 20th century. Oddly enough, Mazzoli first learned about Eberhardt while listening to NPR. Years later, she stumbled upon the explorer's journals in a bookstore.
From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish. Thousands of protesters flooded the streets of Egypt today, some in support of Islamist President Mohamed Morsi, others condemning what they called a power grab by the president that puts Egypt on the path to one-man rule. It is, in short, a nation visibly divided today. NPR's Leila Fadel joins us now from Cairo.
It is now the day after and unless your Thanksgiving dishes were completely consumed by family and friends - maybe even licked clean - you've likely got some leftovers in the fridge and possibly a little holiday hangover when it comes to eating the exact same meal again. Katie Workman got us through a pre T-day crunch earlier this week. She's the author of the "Mom 100" cookbook and the creator of the "Mom 100" blog. We're going to ask her for some ideas on what do to with the leftovers. Hey there, Katie.
Editor's Note: Throughout the Syrian uprising, the government has allowed few foreign journalists and other outsiders into the country, and there has been limited information about life in many parts of the country. In this essay, a Syrian citizen describes life in the capital, Damascus. For security reasons, NPR is not identifying the author.
Children play in an orphanage in Moscow. While some Russian officials are critical of foreign adoptions, the U.S. and Russia are finalizing an agreement designed to improve the safety and quality of adoptions of Russian children by American families.
Americans have been adopting Russian children in sizable numbers for two decades, and most of the unions have worked out well. But it remains a sensitive topic in Russia, where officials periodically point to high-profile cases of abuse or other problems.
Now, the two countries are putting the finishing touches on a new agreement governing these adoptions. It will make the process costlier and more time-consuming, but it's designed to address a host of concerns.
Some Russian officials still seem to bristle at the very thought of foreigners adopting Russian children.

The Ig Nobel Prizes honor scientific research that, in the words of Master of Ceremonies Marc Abrahams, "first makes you laugh, and then makes you think." This year's prizes, awarded in late September, include citations for research into mysteriously green hair, potentially explosive colonoscopies, and the creation of equations that model the back-and-forth swing of a ponytail in motion.
Get out a pencil and paper and your graphic calculator because it's time for a little math review. And we'll warm up with some algebra, move on to imaginary numbers, then the quadratic formula, and we're going to finish up with a bit of vector calculus, how about some probability theory thrown in. No, no, no, I'm just joking. Don't turn off the radio just yet.
Up next, some food for thought as you chomp your Thanksgiving leftovers. Recycling paper and plastic, as you know, is an effective way to save money and energy. So why not recycle all the uneaten food that goes to waste? And there is an awful lot of it. Forty percent of the food in the U.S. today goes uneaten, which means Americans are throwing out the equivalent of $165 billion worth of food each year. But that's not all. Food waste, as it decays in landfills, also produces methane, which is a potent greenhouse gas.
