Though some scientists chalk uo the latter to fluctuations in weather, others say it's a sign that the grasslands are starting to return to health. "Maybe some places...
...eighth month of 2001, the clock struck midnight on stem- cell research. After 9 p.m. on Aug. 9, 2001, therapeutic cloning—the production of new stem cell lines from early embryos—was officially denied federal funding. Since that time, researchers studying everything from tissue regrowth to cell differentiation have faced an unpleasant choice: use expensive, often poor-quality federal stem-cell lines, if they are available at all, or seek substantial amounts of private money to generate new ones...

"Your initial goal is to keep the immune response in check, but then you have to ask how you encourage regrowth of damaged tissue," says Dr. Stephen Reingold, vice president for research programs at the National Multiple Sclerosis Society.
