G8 leaders must encourage cooperation in biotechnology to address Africa's food shortages, writes Calestous Juma.

Africa needs a Green Revolution, including local research into genetically engineered crops for small farmers, says Robert Paarlberg.

Small farmers could beat increasing prices in food and fertiliser by producing more of their own crops at lower cost, argues William Dar.

Non-communicable disease treatment has a lot to learn from tuberculosis control programmes, say Anthony D. Harries and colleagues.

Doruk Ozgediz and Robert Riviello make the case for devoting more resources to easily treated surgical conditions in Africa.

Kenya should establish a nanotechnology curriculum to get ahead of the game, say Macharia Waruingi and Jean Njoroge.

Calestous Juma argues that G8 countries should support provision of cheap, fast Internet access in Africa — particularly to universities.

South Africa's rating system for researchers belongs to the past, but its administrators are reluctant to change, says Michael Cherry.

Public-private partnership organisations have failed to include African researchers on an equal basis, say T. J. Tucker and M. W. Makgoba.

Developing-world scientists should make every effort to pursue careers at home – and their governments should help them, says Mohamed Hassan.

African malaria research networks have helped scientists combat the disease, but they need more stable support and longer-term funding, says Thomas Egwang.

Renewed political commitment means China and India could set the pace for bilateral South–South collaboration, say Purnima Rupal and Dinesh Abrol.

Thousands of traditional crop species could help break dependence on a few global food crops, and offer valuable environmental services, says Monty Jones.

Better education, effective communication and dissemination of information could quell dangerous pseudoscience, argues George Claassen.

Africa and India are struggling in the fight against tuberculosis, say Richard E. Chaisson, Neil A. Martinson and Vikram Paralkar.

Let's encourage the mood of political cooperation on the big issues during the International Year of Planet Earth, says Nasser Ennih.

The UN is inhibiting innovation through over-regulation of new biotechnologies, argues Henry I. Miller.

Uganda's enforcement of science education to boost industrialisation has failed for a number of reasons, writes Deo T. Kabwende.

More research is needed to see whether the success of the WHO's tuberculosis programme is at risk, say G. E. Davies and S. B. Squire.

Revised HIV/AIDS figures are a sign of better data, not that the epidemic is slowing. There is still much to be done, says Kevin De Cock.
