This November, voters in California will decide whether the state should require labels on foods with genetically engineered ingredients. If the initiative, known as Proposition 37, passes, manufacturers would have to say somewhere on the front or the back of the food's packaging if the product contains or may contain genetically engineered ingredients.
Farmers markets are popping up in cities all across the country, and people expect lots of different things from them: Better food, of course, but also economic development and even friendlier neighborhoods.
At its core, though, the farmers market is a business, and it won't survive unless the farmer makes money.
We turn now to my co-host, Robert Siegel, who's at the Republican National Convention in Tampa, where tonight Mitt Romney accepts his party's nomination for president.

For every farmer who is hurting this year during the drought, others are benefiting. Many fields in the South, Northwest and Upper Midwest are producing bountiful corn crops. And because the drought has pushed prices to record highs, farmers who have corn to sell expect a terrific payday.
"The corn has actually really, really taken off all the way through season. It's grown fast. It's been accelerated. The corn looks really good now," says John Scott, whose family farm in Sargeant, Minn., is just bursting with corn.
There were many problems across Louisiana and Mississippi Thursday as people dealt with the aftermath of Isaac. In Slidell, La., water began to flood the historic downtown area and police needed to do house-to-house rescues.
Scientists in Germany have been able to get enough DNA from a fossilized pinky to produce a high-quality DNA sequence of the pinky's owner.
"It's a really amazing-quality genome," says David Reich of Harvard Medical School in Boston. "It's as good as modern human genome sequences, from a lot of ways of measuring it."
The pinky belonged to a girl who lived tens of thousands of years ago. Scientists aren't sure about the exact age. She is a member of an extinct group of humans called Denisovans. The name comes from Denisova cave in Siberia, where the pinky was found.
Almost daily, Taliban assassins target Afghan government officials and community elders with ambushes or bombings. The United Nations says such killings are up more than 50 percent compared to the same period last year.
On Monday, the target was the powerful police chief in southern Afghanistan's Kandahar province. A suicide bomber struck the convoy of Gen. Abdul Raziq, who survived the attack and is at a U.S. military hospital recuperating from burns and other injuries.
The U.S. and other Western countries are often trying to isolate Iran, but this week the country is in the international spotlight as it hosts a summit of 120 nonaligned nations.
U.N. Secretary-General Ban Kim-moon decided to go, ignoring the advice of Israel and the U.S. He promised to deliver a tough message, but others are skeptical, arguing that his visit plays into the hands of the Iranians and to U.N. detractors in Washington.
