Dan Charles

Dan Charles is NPR's food and agriculture correspondent.

Primarily responsible for covering farming and the food industry, Charles focuses on the stories of culture, business, and the science behind what arrives on your dinner plate.

This is his second time working for NPR; from 1993 to 1999, Charles was a technology correspondent at NPR. He returned in 2011.

During his time away from NPR, Charles was an independent writer and radio producer and occasionally filled in at NPR on the Science and National desks, and at Weekend Edition. Over the course of his career Charles has reported on software engineers in India, fertilizer use in China, dengue fever in Peru, alternative medicine in Germany, and efforts to turn around a troubled school in Washington, DC.

In 2009-2010, he taught journalism in Ukraine through the Fulbright program. He has been guest researcher at the Institute for Peace Research and Security Policy at the University of Hamburg, Germany, and a Knight Science Journalism fellow at the Massachusetts Institute of Technology.

From 1990 to 1993, Charles was a U.S. correspondent for New Scientist, a major British science magazine.

The author of two books, Charles wrote Master Mind: The Rise and Fall of Fritz Haber, The Nobel Laureate Who Launched the Age of Chemical Warfare (Ecco, 2005) and Lords of the Harvest: Biotech, Big Money, and the Future of Food (Perseus, 2001) about the making of genetically engineered crops.

Charles graduated magna cum laude from American University with a degree in economics and international affairs. After graduation Charles spent a year studying in Bonn, which was then part of West Germany, through the German Academic Exchange Service.

A tablespoon of soil contains billions of microscopic organisms. Life on Earth, especially the growing of food, depends on these microbes, but scientists don't even have names for most of them, much less a description.

That's changing, slowly, thanks to researchers like Noah Fierer, at the University of Colorado, Boulder. Fierer think microbes have lived in obscurity for too long. "They do a lot of important things for us, directly or indirectly, and I hope they get the respect they deserve," he says.

For more than a century, corn has been the most widely planted crop in the country and a symbol of small-town America. Think of the musical Oklahoma, where the corn is as tall as an elephant's eye, or the film Field of Dreams, in which old-time baseball players silently emerge from a field of corn.

Even farmers are partial to corn, says Brent Gloy, who grows some himself, on a farm in Nebraska. (He also graduated from the University of Nebraska. You know, the Cornhuskers.)

Gerry Newman buys vanilla by the gallon. He's co-owner of Albemarle Baking Co., in Charlottesville, Va., and vanilla goes into everything from his cookies to pastry cream.

A few years ago, each 1-gallon bottle of organic, fair-trade vanilla set him back $64. Today, it's $245, more than Newman can comfortably stomach.

It's a global phenomenon, hitting pastry chefs and ice cream makers alike. Some have changed their recipes to use less vanilla. Newman has switched suppliers to find a cheaper product.

Dan Fazio says his phone is "ringing off the hook" these days.

He's executive director of WAFLA, an organization that helps fruit growers in Washington state find workers — and specifically, foreign workers who are allowed to enter the U.S. specifically as seasonal workers on farms.

Nobody loves pesticides, exactly. But one kind of pesticide, called neonicotinoids, is provoking a particularly bitter debate right now between environmentalists and farmers. The chemicals are highly toxic to bees. Some scientists think they are partly to blame for the decline in pollinators.

For the past year, the province of Ontario, in Canada, has responded to the controversy with a novel experiment. Ontario's government is asking farmers to prove that they actually need neonicotinoids, often called neonics. It turns out that "need" is a word that's hard to define.

The nation's first "soda tax" on sugar-sweetened beverages, which went into effect in Berkeley, Calif., last year, appears to be working.

According to a new study, consumption of sugary drinks — at least in some neighborhoods — is down by a whopping 20 percent.

After years of bitter debate and legislative stalemate over the labeling of genetically modified ingredients, a compromise proposal sailed through Congress in breathtaking speed over the past three weeks.

The House of Representative passed the measure on Thursday with solid support from both Democrats and Republicans. It now goes to the White House, where President Obama is expected to sign it.

One of the country's leading poultry companies, Perdue Farms, announced plans Monday to make both life and death a little easier for its chickens.

The changes are a break with current standard practices in the industry, and animal welfare groups are cheering.

Jim Perdue, chairman of Perdue Farms, says there's a simple motivation behind the new initiative. Consumers, especially millennials, "want to make sure that animals are raised in as caring a way as possible. With the least stress, the least discomfort."
