We collected 118 soil samples from seven African countries and analyzed them for lead. Contamination levels ranged up to 14% lead. As the lead battery industry continues to expand, it is expected that the number and size of lead battery recycling plants will increase. There is an immediate need to address ongoing exposures, restrict emissions, and to regulate site closure financing procedures to ensure that we do not leave behind a legacy of lead contamination.
Climate change has scientists worried that birds' annual migration and reproduction will be thrown out of sync with the seasons. Because birds' songs are correlated with their breeding behavior and are easily identifiable to species, monitoring birdsong can be a good way to keep tabs on this possibility, and a new study from The Condor: Ornithological Applications takes advantage of this approach to provide new baseline data for the birds of northern California.
NASA's Terra satellite passed over the Southern Indian Ocean and saw Tropical Cyclone Berguitta moving southwest toward the island of Mauritius. A tropical cyclone alert class 2 is in effect for Mauritius.
Pharmaceuticals and other man-made contaminants are forcing fish that live downstream from a typical sewage treatment plant to work at least 30 percent harder just to survive, McMaster researchers have found.
ETH researchers reveal why Arctic sea ice began to melt in the middle of winter two years ago -- and that the increased melting of ice in summer is linked to recurring periods of fair weather.
Research led by the University of Plymouth shows more than half of the forests across Europe have been lost over the past 6,000 years.
Nitrogen-based synthetic fertilizer forms the backbone of the world food supply, but its manufacture requires a tremendous amount of energy. Now, computer modeling at Princeton University points to a method that could drastically cut the energy needed by using sunlight in the manufacturing process.
Shale gas is one of least sustainable options for producing electricity, according to new research from The University of Manchester.
Roughly 10 percent of nitrogen-fixing microorganisms contain the genetic code for manufacturing a back-up enzyme, called iron iron-only nitrogenase, to do their job. New research reveals that this enzyme allows these microorganisms to convert nitrogen gas to ammonia and carbon dioxide into methane at the same time. This enzymatic pathway is a previously unknown route for the natural biological production of methane.
NOAA's JPSS-1 satellite provided a visible image of the tropical storm after it made landfall along the Pilbara Coast in the northwestern part of Western Australia.
