Available genetic data could help doctors make better use of cardiovascular drugs

Mon, 01/06/2015 - 5:48pm
Few heart specialists make use of published information about interactions between drugs used to treat cardiovascular disease and the genetic variations that affect how patients respond to them, researchers say. As a result, a group of physicians combed through the literature on the pharmacogenomics of the leading cardiovascular drugs and compiled summaries.

The ebb and flow of Greenland's glaciers

Mon, 01/06/2015 - 4:25pm
In northwestern Greenland, glaciers flow from the main ice sheet to the ocean in see-sawing seasonal patterns. The ice generally flows faster in the summer than in winter, and the ends of glaciers, jutting out into the ocean, also advance and retreat with the seasons. Now, a new analysis shows some important connections between these seasonal patterns, sea ice cover and longer-term trends.
