| am vazut multe(2008-05-17) -- The newest analysis of trace gases trapped in Antarctic ice cores now provide a reasonable view of greenhouse gas concentrations as much as 800,000 years into the past, and are further confirming the link between greenhouse gas levels and global warming, scientists have reported in Nature. |

beverages
| Study participants who drank a non-caloric diet cola ate about the same amount at lunch as when they had no beverage at all. Participants ate somewhat less at lunch after drinking any of the caloric beverages, but only partially compensated for the calories they consumed in the beverage. People who drank any of the caloric beverages -- whether cane-sweetened cola, one of the high-fructose sweetened colas, or 1 p |
through
| am vazut multe(2008-02-22) -- Ice core records from Antarctica and Greenland show greenhouse gas signatures consistent with climate inferences assumed from records of oxygen isotope fractions through time. Noting that atmospheric methane decays quickly, one researcher seeks to understand what kind of methane source is capable of sustaining the levels and concentrations of methane seen in the ice core record. |

| The study is authored by Dr. Pablo Monsivais, research fellow in the UW Nutritional Sciences Program, and co-authored by Drewnowski and UW graduate student Martine Perrigue. |
atmosphere
| am vazut multe(2006-08-30) -- Periods of warming temperatures during the last ice age triggered the release of methane from beneath the ocean, according to U.S. and French researchers. Once in the atmosphere, the methane would have acted as a heat-trapping greenhouse gas. |

| "Some companies have made a sincere effort to put sucrose back in soda," said Dr. Adam Drewnowski, director of the Nutritional Sciences Program at the University of Washington and the senior author of the study. "But there is no direct link between the type of sweetener and obesity. As far as appetite is concerned, cane and corn sugars in beverages are much the same." |
reacted
| am vazut multe(2004-12-22) -- A team of University of Minnesota scientists has discovered how iron- and chromium-rich rocks can generate natural gas (methane) and related hydrocarbons when reacted with superheated fluids circulating deep beneath the floor of the Atlantic Ocean. |
The results suggest that while appetite and food intake are influenced by the number of calories consumed earlier, the types of sugars consumed in tho
| The results suggest that while appetite and food intake are influenced by the number of calories consumed earlier, the types of sugars consumed in those calories seem to make little or no difference. |
vent
| am vazut multe(2008-02-05) -- Hydrocarbons -- molecules critical to life -- are being generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the mid-Atlantic Ocean. Being able to produce building blocks of life makes Lost City-like vents even stronger contenders as places where life might have originated on |
publishes
| The American Chemical Society is a nonprofit organization, chartered by the U.S. Congress, with a multidisciplinary membership of more than 159,000 chemists and chemical engineers. It publishes numerous scientific journals and databases, convenes major research conferences and provides educational, science policy and career programs in chemistry. Its main offices are in Washington, D.C., and |
minerals
| am vazut multe(2007-11-13) -- A project to learn more about extracting energy from hot rocks on land should give clues about "black smokers," hydrothermal vents that belch superheated water and minerals deep below the ocean. |
researchers
| Dark-colored honey, such as buckwheat honey, is generally thought to contain higher levels of antioxidants than the light-colored varieties, according to the scientists. Previous studies by the researchers suggest that honey may have the same level of disease-fighting antioxidants as that of some common fruits. |
country
| am vazut multe(2008-05-12) -- Australia is uniquely endowed with heat-producing elements under its surface that could provide potentially unlimited amounts of geothermal power for this country, say geoscientists. West of the line between Cairns and the mouth of the Murray River lies a belt of rocks containing the enriched elements uranium, thorium, and potassium that are around 1.5 billion years old. |
