The revised malaria death toll suggests a need for research into uncertainties in controlling neglected tropical diseases, says Mark Booth.

India's carefully targeted strategy against polio holds lessons for other countries, and for other diseases, argues Priya Shetty.

Encouraging demand for new and increasingly cheap interventions available now can boost health in developing countries, says Charles Kenny.

New clinical trial designs can work for testing both Western and traditional medicines, argue Liang Liu and colleagues.

Countries are using innovative schemes to train and retain health professionals — but they need support, says WHO expert Manuel M. Dayrit.

Neither dispassionate information nor scare stories are the answer: we need public engagement on health interventions, argues Priya Shetty.

Health systems in developing nations aren't ready for the diseases that accompany ageing, writes Priya Shetty.

'Boundary organisations' offer a space away from politics for scientists to engage government officials with their research, says Scott Drimie.

Healthcare policies and research strategies in developing countries must adapt to the new big killers, says Priya Shetty.

Population forecasts may be based on unrealistic assumptions of demographic change in the developing world, warns Carl Haub.

Health scientists in developing countries can use social media to tackle research priorities, argue Alexander E. T. Finlayson and colleagues.

Assessing each country's needs is key to ensuring that medical technologies fulfil their promise, say Sidhartha R. Sinha and Michele Barry.

Commercial antibody blood tests for TB have been declared ineffective by the WHO, but it is up to governments to halt their use, writes epidemiologist and TB researcher Madhukar Pai.

Excitement about new drug treatment for HIV prevention does not mean we should lose sight of other methods, cautions Priya Shetty.

Developing world scientists should be empowered to do their own medical genomics research, say Carlos D. Bustamante and colleagues.

Reproductive and sexual health programmes in the developing world are more effective if they engage both sexes, says Priya Shetty.

Three key approaches could reduce the number of cholera cases and prevent diseases of poverty in Haiti, say experts in PLoS NTDS.

Impact studies warn that TRIPS-Plus provisions can lead to higher prices and reduced access to medicines, say Nusaraporn Kessomboon and colleagues.

Vaccination campaigns to eradicate polio must change how they engage with local communities, say Heidi J. Larson and Isaac Ghinai.

The WHO should make the most of its strengths as a provider of technical and practical information, says public health expert Barry R. Bloom.
