Poverty Collection
The Council of Science Editors has organized a Global Theme Issue on Poverty and Human Development on October 22, 2007. More than 200 science and health journals, including three PLoS journals, are participating by publishing new articles. We have also collected together related articles with a poverty theme from the archive of all the PLoS journals.
Challenges Collection
This collection of brief provocative discussion papers, initiated and edited by Simon Levin, aims to highlight fundamental questions in biology that help unify different biological disciplines.
Oceanic Metagenomics Collection
The J. Craig Venter Institute's Global Ocean Sampling Expedition reveals an enormous amount of previously unexplored diversity in the world's oceans. In addition to three research articles, this collection includes commentary and analysis highlighting the achievements and challenges of this work.
