Science Magazine special issue on cities

In its 8 February 2008 issue, Science explores the ramifications of urban transformation. News articles offer an on-the-ground look at how cities are tackling specific problems from poverty and sanitation to traffic jams. Reviews and Perspectives examine how cities take shape and the impacts of urbanization on the environment, human health, economic growth, and the demographics of the developing world. A related podcast segment discusses the tradeoffs between urban living and fertility, and an online video presentation accompanies the issue.
