In general, the study concludes that importing regions now paying higher prices will experience relative rate reductions if they obtain more transmission access, while low-cost exporting regions will experience higher prices. ``These rate adjustments reflect the search for the rig...Study looks at causes, consequences of sex differences

According to the report, the case for public funding is made even stronger by the amount of stem-cell research taking place in the private sector without public ...Scientists shake up "family tree" of green plants
... as the journal Nature's cover story on February 1 concludes that ferns and horsetails are not -- as currently believed -- lower, transitional evolutionary grades between mosses and flowering plants. In fact, ferns and horsetails, together, are the closest living relatives to seed plants. "Today's systema...Fewer airline crashes linked to 'pilot error'
...fic study of aviation crashes in the United States concludes that "pilot error" is a decreasing cause of crashes involving major airlines. Johns Hopkins researchers report that pilot error accounted for 34 percent of major airline crashes between 1990 and 1996, compared with 43 percent from 1983 to 1989.

A large nationwide study concludes that a drug called etanercept dramatically slows or even stops the progress of rheumatoid arthritis (RA) at the earliest stages of the disease, helping nearly three-quarters of those taking it.
