Worldwide Sulfur Emissions Rose Between 2000-2005, After Decade of Decline

globalemissions.jpg

A new analysis of sulfur emissions shows that after declining for a decade, worldwide emissions rose again in 2000 due largely to international shipping and a growing Chinese economy. An accurate read on sulfur emissions will help researchers predict future changes in climate and determine present day effects on the atmosphere, health and the environment.

New Explanation for Heart-Healthy Benefits of Chocolate

In time for the chocolate-giving and chocolate-eating fest on Valentine’s Day, scientists are reporting discovery of how this treat boosts the body’s production of the “good” form of cholesterol that protects against heart disease. Polyphenols in chocolate rev up the activity of certain proteins, including proteins that attach to the genetic material DNA in ways that boost “good” cholesterol levels. Their report appears in the American Chemical Society’s Journal of Agricultural and Food Chemistry.

Experiment Reaches Biology Breakthrough with Hard X-Ray Laser

fsnanocrystallography-3.jpg

A pair of studies published Feb. 3 in Nature, detail a new method developed to determine structures of biomolecules based on diffraction from protein nanocrystals. The international team of nearly 90 researchers included 10 from Arizona State University, whose contributions included a protein beam injector and nanocrystals.
