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.

New funding and concrete results are paving the way for scaling up mhealth technologies — but carefully, writes Priya Shetty.

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

Christian Lienhardt and colleagues outline where research and innovation must advance to meet the goal of eliminating tuberculosis.

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

Much progress has been made in genomics research, says Stephen Baker, but the impact on public health is limited in the developing world.

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.

Several collaborations between researchers and indigenous communties are underway, but more needs to be done, says Henry P. Huntington.

Amanda Glassman director of Global Health Policy argues that a joined up approach is needed if mHealth is to transform health systems.

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.

We must find a better way of monitoring the impact of food insecurity, argues Derek D. Headey.

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

Developing countries forging ahead with nanotechnology need regulation and research into local risk patterns, say Alok Dhawan and Vyom Sharma.

Diseases, and drugs used to treat them, behave differently in men and women. Drug development needs to account for this, says Priya Shetty.
