Posting the calorie content of menu items at major fast-food chains in Philadelphia, per federal law, hasn't change purchasing habits or decreased the number of calories that those customers consume, researchers reported Friday at the Obesity Society's annual scientific meeting, held in Atlanta.

Laboratory animals fed a modified version of a common genetically modified probiotic were completely cured of intestinal worms that belong to a family of parasites that currently infect 1.5 billion people, or almost one quarter of the world's population, according to new research presented today at the annual meeting of the American Society of Tropical Medicine and Hygiene (ASTMH).

New research from the University of Washington Information School and Harvard University, followed 20 years of student creative writing and visual artworks and finds that the dynamics of creativity are changing.
