Researchers solve piece of large-scale gene silencing mystery Thu, 04 Dec 2008 00:00:00 EST	(Washington University in St. Louis) A team led by Craig Pikaard, Ph.D., WUSTL professor of biology in arts and sciences, has made a breakthrough in understanding the phenomenon of nucleolar dominance, the silencing of an entire parental set of ribosomal RNA genes in a hybrid plant or animal. Since the machinery involved in nucleolar dominance is some of the same machinery that can go haywire in diseases such as cancer, Pikaard and his collaborators' research may have important implications for applied medical research.

Bonefish census reveals population holding steady Thu, 04 Dec 2008 00:00:00 EST	(University of Miami Rosenstiel School of Marine & Atmospheric Science) If you're looking for bonefish from Miami down to the Marquesas , you have about 321,000 to choose from -- that is down slightly from the average of previous censuses. According to UM Rosenstiel School's Dr. Jerry Ault, co-founder of the census, statistically there is no significant difference year over year, which can be attributed to a variety of factors. This year 64 professional fishing guides, scientists and graduate students covered 1,575 square miles in the census of the Keys. [go to news]
A little wine boosts omega-3 in the body: Researchers find a novel mechanism for a healthier heart Thu, 04 Dec 2008 00:00:00 EST	(Catholic University) Moderate alcohol intake is associated with higher levels of omega-3 fatty acids in plasma and red blood cells. This is the major finding of the European study IMMIDIET that will be published in the January issue of the American Journal of Clinical Nutrition. The study suggests that wine does better than other alcoholic drinks. This effect could be ascribed to compounds other than alcohol itself, representing a key to understand the mechanism lying behind the heart protection observed in moderate wine drinkers. [go to news]

Tropical forest carbon monitoring gets big boost Thu, 04 Dec 2008 00:00:00 EST	(Carnegie Institution) A new and improved tool to monitor deforestation and degradation in tropical forests has just gotten a huge boost. The Gordon and Betty Moore Foundation has awarded the Carnegie Institution's Department of Global Ecology with a $1.6-million grant to expand and improve the Carnegie Landsat Analysis System Lite. The technology will rapidly advance deforestation and degradation mapping in Latin America and will help even the smallest governments and non-governmental organizations better monitor carbon budgets.

Golf course: Playing fields, wildlife sanctuaries or both Wed, 03 Dec 2008 00:00:00 EST	(University of Missouri-Columbia) Semlitsch and Mark Mackey, a graduate student at MU, are examining the effect of golf courses on salamander populations. Working with 10 golf courses in North Carolina, Semlitsch and Mackey are measuring stream salamanders' abundance and diversity in order to make biologically relevant management suggestions for golf course superintendents. The researchers are hoping to balance human recreation with the protection of wildlife. [go to news]
Managing carbon loss Wed, 03 Dec 2008 00:00:00 EST	(American Society of Agronomy) The push for alternative energy has created a large demand for corn stover, a popular feedstock used to produce cellulosic ethanol, but utilizing these materials, rather than using it as compost, means a loss of soil organic carbon. Researchers have studied the effectiveness of alternative carbon augmentation practices and have reported positive results, as detailed in the November-December 2008 issue of Agronomy Journal.
