- Tropical plants go with the flow ... of nitrogen
05-07-2007 · EurekAlert!
Tropical plants are able to adapt to environmental change by extracting nitrogen from a variety of sources, according to a new study. By demonstrating that not all plants specialize in one specific source of nitrogen, the result turns a commonly held theory on its head. It also provides a dose of optimism that tropical forests will be able to withstand environmental shifts in nutritional cycles brought on by global climate change.

- Pervasive environmental sensing a possibility
01-31-2008 · EurekAlert!
Researchers from MIT and two Singaporean universities have launched a bold new international research program called CENSAM. The program will develop pervasive environmental sensor networks to collect data on parameters such as air and water quality from many sources, and use this data to provide accurate, real-time monitoring, modeling and control of the environment.

- Context affects opinion about novel energy sources
07-12-2007 · EurekAlert!
Opinions people have about innovations are influenced by the context in which they form their opinion. For example, opinions about a novel energy source like biomass are influenced by thoughts regarding other energy sources. The less knowledge, interest or time people have, the stronger this effect. Sustainable energy options must therefore be promoted in the right context, says Dutch researcher Wouter van den Hoogen.

- Gold nanoparticles help detect a toxic metal -- mercury
04-27-2007 · EurekAlert!
With gold nanoparticles, DNA and smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and oceans, to evaluate their safety as food and drinking water sources. An article detailing the technology's success will be published online April 27 by Angewandte Chemie, the prestigious European journal of applied chemistry.
