...Scientists believe that embryonic stem cells are more versatile than adult cells in generating the more than 200 different tissue types in the body. The need for healthy new cells is particularly acute in the case of spinal-cord injury, because once central-nervous-system tissue is destroyed, it does not regenerate - not in any significant way, at least. The Geron team began its work with what is known as a presidential stem-cell line - stem cells derived from discarded in vitro-fertilization embryos that already existed in 2001 when then President Bush decided to prohibit the use of federal...
...GRNOPC1. By having more of these cells around the spinal cord, more nerves might be repaired and can then potentially re-establish proper connections. Simply by working with the GRNOPC1 cells, Geron scientists have learned more about how they operate, which will expand their understanding of how the central nervous system might be healed. Says Geron's president and CEO, Dr. Thomas Okarma: "They make dozens of factors that can stimulate nerve function, growth and regeneration." (Read "Scientists Reach Stem-Cell Milestone...
...countries with deposits like Chile, Argentina and China, seems to be less hazardous than other kinds of mineral extraction. "Lithium could be one of the least contaminating mining processes," says Marco Octavio Rivera of Bolivia's Environmental Defense League, although he notes that prolonged exposure to lithium can cause nervous system disorders...
...Clearing access to credit for banks, firms and consumers is crucial. Interest rates may be at their lowest since the Bank of England was created more than 300 years ago, and the banking industry may have already received $55 billion in government money, but nervous British lenders are simply not lending enough. The result: British GDP will tumble 2.7% this year, Ernst & Young forecast on Monday, the biggest drop since 1946. "Without additional government intervention," it added, "a deep recession could evolve into a depression...

Two weeks in the first grade of the Chadds Ford school made Andy "nervous," so his father generously took him out and supplied a tutor until he was 16. He grew up like Peter Pan, a prisoner of fantasy. "As a kid," he says, "I adored Robin Hood, D'Artagnan, and"-he adds innocently-"Dracula." N.C. designed an immense castle, which his eldest son, Nat, built for the children's playroom. Andy became its lord and staged jousts within its battlements...
