Findings





1 Are those sweet peppers you just bought really organic? Scientists have discovered a way to find out, using nitrogen isotopes to detect synthetic  fertilizers. The method could help identify fraud in the burgeoning organic produce industry. 2 Twenty-one percent of global carbon emissions come from manufacturing activities in developing nations aimed at meeting the needs of developed countries. This could partly explain why CO2 emissions have risen 35 percent since 1990, despite reduction efforts by some developed nations.

3 The peanuts and other treats birds get in the winter from backyard feeders helps them breed more successfully in the spring.

4 Oil and natural gas typically come from decomposed organic material like plants and trees. But researchers found evidence that the fuels can come from inorganic sources: deep-sea vents that produce natural gas and hydrocarbons, the building blocks of oil.

5 The recent discovery of a previously unknown species of uakari monkey in the remote Amazon has a sad twist: The animal is already endangered because of hunting and limited habitat.

6 A new water purification facility in California’s Orange County will treat sewage from industrial and household wastewater and churn out 70 million gallons of drinkable water per day (enough for about 10 percent of the district’s 2.3 million residents).

7 NOAA scientists are using unmanned aircraft to track environmental degradation and forecast weather. This year, planes with automated sensors will fly into hurricanes, measure Arctic ice conditions, and monitor Pacific Ocean storms that dump rain and snow on the West Coast.

8 The tropical disease dengue fever may spread across the US if global warming continues unabated and measures to control the mosquitos that spread the illness aren’t adequate.
