from the Christian Science Monitor
Often lost in the political wrangling over the controversial Keystone XL pipeline--on hold after President Obama rejected TransCanada's initial construction proposal--are some key findings that run counter to the rosy picture of abundant supply and lower prices so often painted by US politicians.

These little-publicized findings are contained in the studies and testimony of experts working for TransCanada, the company that wants to build the pipeline from Alberta's tar sands across America's heartland to Gulf Coast refineries.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
