Sediment wedge key to glacial environmental stability
03-01-2007 · EurekAlert!A wedge of sediment, pushed up by glacial movement, may be a buffer against moderate sea level rise, pointing to ocean temperature rise as the key factor in glacial retreat, according to two papers published today (March 1) in Science Express.

- Statistical analysis of complex data sets with robust statistical methods
04-11-2007 · EurekAlert!
Robust statistical analysis methods capable of dealing with large complex data sets are required more than ever before in almost all branches of science. The European Science Foundation's three-year SACD network, which was completed in December 2006, developed new methods for extracting key structural features within the data. Such features can include outlying values that may be particularly significant within the increasingly large and complex data sets generated in financial markets, medical diagnostics, environmental surveys, and other sources.

- How plants learned to respond to changing environments
07-12-2007 · EurekAlert!
A team of John Innes Center scientists lead by Professor Nick Harberd have discovered how plants evolved the ability to adapt to changes in climate and environment. Plants adapt their growth, including key steps in their life cycle such as germination and flowering, to take advantage of environmental conditions. They can also repress growth when their environment is not favorable. This involves many complex signalling pathways which are integrated by the plant growth hormone gibberellin.

- Scripps scientists discover fluorescence in key marine creature
10-30-2007 · EurekAlert!
Fluorescent proteins found in nature have been employed in a variety of scientific research purposes, from markers for tracing molecules in biomedicine to probes for testing environmental quality. Until now, such proteins have been identified mostly in jellyfish and corals, leading to the belief that the capacity for fluorescence in animals is exclusive to such primitive creatures.

- Smithsonian researchers develop models to assess wetland health
09-14-2007 · EurekAlert!
In a special issue of the journal Wetlands, Smithsonian scientists report a promising method of wetland assessment that will help environmental managers quickly take stock of wetlands across an entire watershed. Tools for this kind of rapid watershed-scale assessment -- relying on a few easily measurable key factors -- have been previously unavailable to managers.

- Nanowaste needs attention of EPA, industry and investors
07-26-2007 · EurekAlert!
The Environmental Protection Agency must make key decisions about how to apply the two major end-of-life statutes to nanotechnology waste in order to ensure adequate oversight for these technologies, concludes a new report from the Wilson Center's Project on Emerging Nanotechnologies. However, the report notes that the agency lacks much of the data on human health and eco-toxicity that form the basis for such determinations, creating some tough challenges ahead in EPA's decision-making process.

- Cougar predation key to ecosystem health
10-24-2006 · EurekAlert!
The general disappearance of cougars from a portion of Zion National Park in the past 70 years has allowed deer populations to dramatically increase, leading to severe ecological damage, loss of cottonwood trees, eroding streambanks and declining biodiversity. Researchers are calling it a "trophic cascade" of environmental degradation.

- Environment plays key role in children's readiness for school
11-15-2007 · EurekAlert!
Researchers conducting one of the first studies to consider both environmental and genetic influences on school readiness found that environment is the most important factor in individual differences in children's readiness for school. The study involved 420 pairs of 5-year old twins whose achievement was rated by teachers after two years. The findings provide further incentive for continued interventions that address school readiness in at-risk children.
