Valley fever is a dangerous threat to human health – and cases are on the rise in the arid southwestern United States, as wind from increasing dust storms can transport the fungal spores that cause the disease. Valley fever is caused by the Coccidioides fungus, which grows in dirt and fields and can cause fever, rash and coughing. Using NASA resear

Sand Mining at Poyang Lake– As part of an effort to assess the scale of the sand mining and its environmental impacts, a group of researchers analyzed data collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor on NASA’s Terra satellite. Using infrared data collected by ASTER in 2005, the researchers found that the lake was producing up to 236 million cubic meters of sand per year—about 9 percent of the total produced by China. The researchers estimated that the volume of sand removed was probably enough to make Poyang Lake the largest sand mining operation in the world.
