GARLIC. The "lowly stinking rose" may lower blood pressure slightly and help prevent blood clotting, like aspirin. A recent German study showed marked reduction in blood fats, including cholesterol, among people who consumed the equivalent of one clove of garlic a day. The active compounds are probably the same sulfur derivatives that give garlic its distinctive odor. Other studies suggest that sulfur compounds may suppress the development of stomach cancer in humans and breast cancer in laboratory animals. Garlic does not have to be eaten raw, but deep frying and high heat could destroy its active ingredients. If the idea...
...main tools of the volcanologist include seismometers, which record the swarms of tiny earthquakes that occur as the magma rises. Chemical sensors, mounted on airplanes, can detect increases in sulfur-dioxide emissions, indicating that magma has reached the surface. In addition, the physical swelling of mountain slopes, well documented at Mount St. Helens, is a sign of explosive potential. Laser-based devices can pick up minute bulges that are about the width of a nickel and still invisible to the naked eye. In Japan researchers have set up video cameras to monitor the shape and color of fumes...
Even if the rains do come, the sulfur-laden smoke and soot may make the soil too acidic for crops to grow. Considering the scale of these threats, it is surprising that organized efforts to gather information about the fires are only just getting under way. Last week a team of scientists sponsored by the Defense Nuclear Agency, the National Science Foundation and the National Geographic Society, among others, began their first flights to analyze the composition, density and persistence of the smoke. One important question: Does the smoke naturally repel water or, as El-Baz and some other scientists...
...Cities study showed that there were noticeable health effects, such as a substantial increase in respiratory illness in "dirty" cities, that resulted from the burning of coal and other fossil fuels. This process releases sulfur dioxide and other acidic chemicals into the air, said both professors...
Since such a shift did not occur, "we now see decay products of sulfur dioxide that move into acid rain" instead of direct sulfur dioxide pollution, Dockery said...
