ORNL system eliminates perchlorate, helps scientists trace source
...e, Gu said. "The presence of natural or atmospheric
perchlorate in the environment obviously has far-reaching ramifications, ranging from public health issues to huge liabilities that could be imposed by agricultural and environmental cleanup needs," Gu said. "It recently has been found in lettuce and...

phenomena," said Anderson. "There are many more variables that go into this than I would ever have believed when I started studying the Gulf Coast in the 1980s."...
Global warming: Informal networking is the key to a swift response
A recent report on an unexpected sharp rise in atmospheric
CO2 levels has raised the possibility of rapid global warming, but researchers at King's College London warn that some UK businesses, government departments and voluntary sector organisations are better equipped than others to respond to an increased...
New method to measure ancient land elevation developed by Field Museum scientist
...a big influence on climate by altering patterns of atmospheric
circulation. Because this new method is independent of variations in climate, it will allow scientists to identify the impact of elevation on global climate patterns and factor elevation into the study of global climate change. This research also h...

CO2", says CSIRO's Dr Richard Matear. "While initially showing a decrease in calcification up to 1964, ocean warming outweighs the CO2 effect and stimulates recovery of coral reef calcification. Our results represent an average over the entire coral ...
The secret life of acid dust
...d cloud-altering properties are unaccounted for in atmospheric
models. "Calcite-containing dust particles blow into the air and encounter gaseous nitric acid in polluted air from factories to form an entirely new particle of calcium nitrate," said Alexander Laskin, a senior research scientist at the Department o...
NSF funds Panikov's Alaskan Tundra Microbial Observatory project
