Today's Health|Science: Jupiter, inkjet life, breathing easier

Jupiter is yielding stunning images and startling data beamed earthward from a plutonium-powered spacecraft that zipped past the solar system's biggest planet earlier this year as part of an epic 3-billion mile, 9 1/2-year journey to Pluto.

If you print over and over on a single piece of paper, the ink layers will eventually build up a three-dimensional structure. What if, scientists are asking, you use that same inkjet technology to print layers of cells on a tissue matrix? Can you eventually build up a living structure like a heart or a kidney?

For decades, the haze over Maine's Acadia National Park, the acid in Vermont's mountain lakes, and the choking summer air in downtown Boston have - in part - been blamed on power plants in the Midwest belching pollution our way.
