All WorldChanging readers should have SciDev.net near the top of their bookmark lists. The site's content is a graceful counterpart to our somewhat more manic presentation here: science and global development are its main focus, which means coverage of everything from nanotechnology to the ethics of research -- and, of course, the climate.

SciDev.net has just opened up two "Spotlight" sections looking at the role played by key developing nations in both the causes of and solutions for global warming. Spotlight pages for Brazil and China are now available, and one for India should be up soon.

The pages include "policy briefs" and opinion pieces, descriptions of background reading on the subject, and links to relevant websites and organizations. The China page is available in English and Chinese; the Brazil page is available only in English for now.
