High school students are invited to enter the third annual essay contest organized by the Alliance for Science, whose mission is to "heighten public understanding and support for science and to preserve the distinctions between science and religion in the public sphere," as well as to "bring together scientists, teachers, and science-related companies with the many religious bodies that have found no conflict between religion and science." The contest theme this year is "In Darwin's Footsteps," meaning students should write a 1,000-word original essay about "a modern-day scientist, group of scientists, or even a scientific organization that is carrying forward the magnificent tradition of discovery so well represented by Charles Darwin." Register, download a copy of the official rules, and check out the prizes (as well as the tips for writing a winning essay). The contest deadline is February 12.
