Rethinking Refuges? Drifting pollen may bring earlier pest resistance to bioengineered crops
Pollen wafting from bioengineered corn to traditional varieties may be undermining the fight to keep pests from evolving resistance to pesticides.

Fishy Alpha Males
As a way to protect wild fish stocks, raising genetically engineered fish may be futile should some of these modified fish escape into the environment.

Calling All Cows
Last May, tissues from the carcass of a North American cow turned up positive for bovine spongiform encephalopathy–the ailment responsible for mad cow disease. Within hours, the Canadian government traced the animal to the Alberta farm where it had been raised for its 8 years of life. In short order, other members of its herd […]

Spying Genetically Engineered Crops
Environmental Protection Agency scientists are exploring the use of satellites to monitor genetically engineered crops. At ground level, genetically modified corn plants don’t look any different from conventional ones, but data suggest that satellite sensors may be able to read different spectral signatures from the two types of the crop. USDA Most of these genetically […]

Fluid Security—Overcoming Water Shortfalls in the 21st Century
About 70 percent of Earth’s surface is covered with water, some 1.4 billion cubic kilometers of it. Too bad almost 96.5 percent of it’s salty, and another 2 percent is locked away as ice in remote places such as Greenland and Antarctica. All told, just a little more than 1 percent of our planet’s water […]

Local Foods Could Make for Greener Grocers
There was a time not so long ago when people tended to select the ingredients for their meals either from what was available that week at local markets or from out-of-season home-canned, -smoked, or -pickled goods in the family larder. No longer. Maryland cooks can pick up New Zealand lamb or Icelandic salmon any time […]

Global Food Trends
Last year, for the third year in four, world per-capita grain production fell. Even more disturbing in a world where people still go hungry, at 294 kilograms, last year’s per capita grain yield was the lowest in more than 30 years. Indeed, the global grain harvest has not met demand for 4 years, causing governments […]

How Olives Might Enhance Potatoes—and Strawberries
Many people savor the flavor of olive oil. Few who have ever encountered the “cake” that remains after the oil is pressed, however, savor the experience. Thats because the pressed olive flesh ends up in unused, smelly heaps. In the European Union alone, olive processors produce some 8 million metric tons of these rank wastes […]

Bt Cotton: Yields up in India; pests low in Arizona
Two cotton-growing centers that could hardly differ more—small farms in India and industrial fields in Arizona—provide case studies that show the bright side of a widespread genetically engineered crop.

Carnivorous fish nibble at farming gain
Fish farming may ease pressure on wild stocks overall, but for certain species, farms mean a net loss of fish.
