Only a few weeks ago we could still observe them: whole families of wild boar rummaging in the corn fields in early fall, feasting on corncobs. Corn -- or maize, as it's known to scientists -- is a high-energy delicacy for local game, which is why it is used specifically for winter feeding and to divert animals from farmers' fields. Today, with GM (genetically modified) maize acreage increasing worldwide, biologists are discussing a highly controversial question:

In China, we have a saying," Liu says. "We don't kill the hen to get the eggs." Rather than destroying the cyanobacteria, the group has ingeniously reengineered their genetics, producing mutant strains that continuously secrete fatty acids through their cell walls. The cyanobacteria essentially act like tiny biofuel production facilities.

Scientists around the world are currently hard at work genetically engineering new strains of mosquitoes that are poor hosts for diseases such as malaria, dengue and yellow fever, in the hopes of cutting down the spread of these germs. New research suggests, however, that although these insects might succeed in reducing the number of infections, they might also inadvertently boost the severity of remaining ones.
