    Tiny Grains of Rice Hold Big Promise for Greenhouse Gas Reductions, Bioenergy

    Rice is the staple food for more than half of the world's population, but the paddies it's grown in contributes up to 17 percent of global methane emissions -- about 100 million tons a year. Now, with the addition of a single gene, rice can be cultivated to emit virtually no methane, more starch for a richer food source and biomass for energy production, as announced in the July 30 edition of Nature and online.
