...hospitals or aboard aircraft (that's why the U.S. military is putting them only on long-range cruise missiles). The U.S. used a more primitive form of these weapons--known as soft bombs--against Yugoslavia and in the first Gulf War, when cruise missiles showered miles of thin carbon fibers over electrical facilities, creating massive short circuits that shut down electrical power...
...long as all the glycerin, water and other contaminants have been removed--the homemade stuff can gunk up an engine. Meanwhile, British foodmakers like Wal-Mart subsidiary ASDA have started to team up with refineries to turn used cooking oil into legitimate biodiesel fuel, which creates 79% less carbon dioxide than regular diesel. This year ASDA will test its refined waste oil in delivery trucks pluckily labeled THIS VEHICLE IS POWERED BY CHICKEN...
According to the website of the Natural Gas Vehicle Coalition (NGVC), the carbon content of natural gas is lower than that of any other fossil fuel. Natural gas vehicles decrease the amount of exhaust emissions...
...rock. Pillinger's team has developed a miniaturized gas analysis package (GAP) to heat up rock and soil in an oven, process the gases released and analyze them using a mass spectrometer (which measures elements in minute quantities). By recording the temperature at which the heated samples release carbon dioxide, scientists can gauge the presence of a particular carbon isotope that indicates life. Other tests will look for methane, since extremophiles fuel themselves by reducing carbon dioxide to methane. On the surface, methane is readily destroyed by chemical reactions. If the Beagle detects even minute levels of methane, a continuous...
...sessions, researchers asked 10 healthy young volunteers to smoke bidis, flavored and unflavored, as well as their usual filtered brands. An analysis of the volunteers' blood revealed that nicotine levels were significantly higher after they smoked the bidis than after ordinary cigarettes. In some cases, the levels of exhaled carbon monoxide were higher too. "Kids think they're not smoking real cigarettes. Some even think they've stopped smoking if they use these alternatives," says Wallace Pickworth, a pharmacologist with NIDA and lead investigator of the study. "But these cigarettes are delivering highly toxic compounds...
