In this Nature article, three members of the Royal Society call for an advisory group and a network of international laboratories to lay the groundwork for nuclear disarmament and international collaboration. Scientific collaboration has already helped nuclear negotiations, say the authors. But now, the technology needed to support disarmament must be developed.

In this Science article, US-based scientists Kristin M. Lord and Vaughan C. Turekian argue that science diplomacy is critical to US efforts to build positive relationships with foreign societies. They outline roles for US scientists to play — from acting as goodwill ambassadors to collaborating with colleagues overseas. And they highlight the importance of nongovernmental scientific organisations as conduits to foreign societies.

This collection of features and commentaries, published by Nature, reflects the broad spectrum of activities and opinions of members and associates of TWAS, the academy of sciences for the developing world.

With more than three dozen articles written by prominent scientists working on research or policy issues in the South, the collection examines a range of topics in science-based international development — from the relevance of subjects like mathematics or physics, to the increasing roles of biotechnology and renewable energy.

The achievements made and challenges still facing developing countries in key areas like agriculture, health, climate change and energy are also discussed. And evidence from across the South is presented to show how strengthening science can help achieve economic goals and what more is needed to ensure that knowledge and development are shared by all.
