WEEKLY e-LETTER from SCIENCE NEWS
November 29, 2003
Subject: Science News Weekly e-letter

This week's cover story spotlights the threat posed by U.S.--invading termites (with sound effects). News reports focus on the brain-tissue abnormalities of attention-deficit hyperactivity disorder, tiny needles for delivering drugs painlessly, the cell-surface molecule that acts as a door for the SARS virus, and more. Food for Thought talks turkey. MathTrek giggles about fun math in children's books.
