- North America's northernmost lake affected by global warming
09-26-2007 · EurekAlert!
Analyses conducted by researchers from Université Laval's Center for Northern Studies reveal that the continent's northernmost lake is affected by climate change. The research team reports that life in Ward Hunt Lake, located on a small island in the Canadian Arctic, has undergone major transformations within the last two centuries. The speed and range of these transformations suggest that climate change related to human activity could be at the source of this phenomenon.

- Avoiding sweets may spell a longer life, study in worms suggests
10-02-2007 · EurekAlert!
A new study in the October issue of Cell Metabolism, a publication of Cell Press, reveals that worms live to an older age when they are unable to process the simple sugar glucose. Glucose is a primary source of energy for the body, and can be found in all major dietary carbohydrates as a component of starches and other forms of sugar, including sucrose and lactose.

- Prehistoric remains reveal a drastic shift in northern fur seal ecology
05-21-2007 · EurekAlert!
Northern fur seals have experienced major changes in their behavior, ecology, and geographic range of over the past 1,000 years, according to a new study. Using techniques from archaeology, biochemistry, and ecology, a team of researchers has reconstructed the species’ prehistoric geographical range. Among other results, the scientists found that the northern fur seal’s reproductive behavior was very different in the past than it is today.

A new study led by University of Georgia researchers and announced on Wednesday at the American Society for Microbiology meeting in Toronto finds that crenarchaeota, one of the most common groups of archaea and a group that includes members that live in hot springs, use ammonia as their energy source. Such a metabolic mode has not been found in any of the other known high-temperature archaea.

- DNA clues to inform conservation in Africa
05-22-2007 · EurekAlert!
Tracing the evolutionary history of wildlife could improve global habitat conservation, a major Cardiff University study has found. Researchers in the School of Biosciences analysed the African bushbuck -- a common species which lives in most sub-Saharan habitat types -- to test whether DNA similarity between populations living in different habitats can reveal the similarity of those ecoregions now and in the past.

- Scientists reveal structure of gateways to gene control
03-28-2007 · EurekAlert!
The first complete high-resolution map of structures that control how genes are packaged and regulated throughout an entire genome has been compiled by Penn State scientists. The research suggests how certain nucleosomes control whether a gene's function can be turned on. The study reveals an intimate relationship between the architecture of nucleosomes and the underlying DNA sequences they regulate, including a critical gateway that must be unlocked before a gene can be transcribed.
