This undated image made available by Ayako Wada-Katsumata and Andrew Ernst shows the head of a male German cockroach, showing the four major external chemosensory paired appendages pointed towards a flavored test substance dyed blue by researchers. For 30 years, people have been getting rid of cockroaches by setting out sweet-tasting bait mixed with poison. But in the early 1990s, a formerly effective product stopped working. Some cockroaches had lost their sweet tooth, rejecting the corn syrup meant to attract them. Later studies showed they were specifically turned off by the sugar glucose in the syrup. Scientists reported Thursday, May 23, 2013 that the key is an altered behavior of certain nerves that signal the brain about foods. (AP Photo/Ayako Wada-Katsumata, Andrew Ernst)

In this Wednesday, April 10, 2013 photo, a flag autographed by 2004 British Open champion Todd Hamilton hangs on a wall in the clubhouse at the Hend-Co-Hills Golf Course, in Biggsville, Ill. The course, where Hamilton got his start as a child, was purchased by farmer Clark Kelly who plans to plow it into farm land. Across the Midwest, farmers are planting crops on almost any scrap of available land to take advantage of consistently high corn and soybean prices. (AP Photo/Charlie Neibergall)

Empresas Polar chief executive Lorenzo Mendoza points to a bag of corn flour as he gives a news conference at his office in Caracas, Venezuela, Monday, May 13, 2013. Mendoza said Monday that, in his words, "the accusations that we are producing less than last year are false," rejecting President Nicolas Maduro's claims that it's to blame for the country's persistent food shortages. Mendoza offered to buy or rent government-owned corn processing plants to increase Venezuela's production, and food makers say shortages of basic foods like sugar, milk, butter and cornmeal stem from the socialist government's price controls and a lack of foreign currency to pay for imports.

In this April 12, 2013 photo, machines sit in the industrial plant run by Ebococa in Villa Tunari, Bolivia. The one now-defunct factory churned out a million bags of baked coca treats in 2011 and 2012, as well as sweet breads and liquors made from the tough, bitter-tasting coca plant. To enhance the food's edibility, the factory had added sweeteners, corn and cheese flavoring. But to the government's disappointment, the coca food market refused to grow. (AP Photo/Juan Karita)

A ear of corn from last year's harvest lies in a wet field on a farm, Tuesday, May 7, 2013, near Carlisle, Iowa. The USDA's weekly crop progress report showed that just 12 percent of the nation's cornfields have been sown, about one-fourth of the typical pace over the past five years. The numbers have been even worse in the biggest corn-producing state, Iowa, where only 8 percent of the corn crop is in the ground, down from 62 percent the same time last year. The USDA says it's the slowest planting pace since 1995 in Iowa, which was socked by a snowstorm last week. (AP Photo/Charlie Neibergall)

Michael Chichetti, whiskey production manager, pours a bag of corn into a roller mill while making baby bourbon at Tuthilltown Spirits on Wednesday, April 17, 2013, in Gardiner, N.Y. Some call it “grain to glass,” the booze equivalent of the local-food slogan “farm to table,” though in the case of the apple vodka made from Hudson Valley at Tuthilltown, it’s more like “tree to tumbler.” Whatever the name, it’s catching on.
