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

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

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

Health research partnerships do more for development than just tackling illness, argues AIDS vaccine R&D leader Seth Berkley.

Priya Shetty discusses why biomedical research is vital in steering progress towards the Millennium Development Goals.

Moral crusades against HIV/AIDS may have good intentions, but there is no substitute for sound evidence on behaviour change, says Priya Shetty.

Scientists must re-engage with the International AIDS Conference to find a needs-based research agenda say Jessica Justman and Wafaa M. El-Sadr.

Richard Horton, editor of The Lancet, discusses the implications of news that maternal deaths have dropped by nearly a third since 1980.

Maternal health advocates may feel financially threatened by falling death tolls but the data must not be hidden, says Priya Shetty.

A partnership involving the US Food and Drug Administration may speed up delivery of new tuberculosis drug combinations, says Priya Shetty.

New funding mechanisms to support translational research are vital to develop a successful HIV vaccine, says Wayne C. Koff.

Researchers and donors are not giving nutrition the attention it deserves, says Priya Shetty.

Micronutrients help fight disease — it's time to turn knowledge into action, say nutrition researchers Andrew Thorne-Lyman and Wafaie Fawzi.

A truth commission can account for South Africa's past HIV/AIDS denialist policies and rebuild trust, says AIDS expert, Salim S. Abdool Karim.

A UNITAID patent pool could revolutionise HIV treatment and research in developing countries — if payment can be agreed, says Priya Shetty.

More research is needed on how to tackle HIV with antiretroviral therapy, say Kevin M De Cock and colleagues at the WHO.

New and existing HIV/AIDS treatments provide hope that the disease can be eliminated, says an editorial in New Scientist.

Mobile phones can improve health services and provide help for displaced patients during political crises, say Richard Lester and Sarah Karanja.

Other countries could learn from Vietnam's progress on communicating science and risk, says Son Kim Phan.

China's improved accessibility to HIV/AIDS statistics is a good start to the disease's control in the country, says an editorial in Nature.
