Latin America is embracing the free access movement in its scientific production, but there are structural and economic challenges, says Carla Almeida.

Bioeconomy opens up development opportunities for Latin America, but it also involves several risks, says Federico Vasen.

Scientists in developing countries should increase the quality of their research by publishing more good papers, not fewer, says Rafael Loyola.

Along with investment in science popularisation policies, new ways to bring science and society together are needed, says Carla Almeida.

Disabled people are thought to make up about a seventh of the world's population, so why are they often ignored in housing research, asks Sue Coe.

Initiatives to boost public participation on S&T policies must clarify their objectives and their impact should be assessed, says Carla Almeida.

By measuring the right things, health providers can improve HIV response and save lives, says Stefano Bertozzi of the Gates Foundation.

The new bill is unlikely to achieve its goals without a shift in views about how knowledge is gained and used, says policymaker Arnoldo Ventura.

When it comes to the environment, there is no dialogue between civil society, the scientific community, government and parliament, says Carla Almeida.

How scientific knowledge is presented in public debate, by scientists or journalists, has a big influence on its impact, says David Dickson.

Disaster warnings can be fast, but how can we also ensure their accuracy and credibility, ask Rohan Samarajiva and Nalaka Gunawardene.

In addition to programmes for training abroad, Latin America needs measures and organisations for the promotion of science, writes Carla Almeida.

A third industrial revolution based on new communication and energy technologies needs strong political commitments, argues David Dickson.

Climate Innovation Centers can promote clean technologies but need backing with a coordinated effort, says policy specialist Ambuj Sagar.

Journalists can help the developed world take responsibility for climate change by making it relevant to readers' lives, says David Dickson.

As the Obama administration begins a second term, USAID's Alex Dehgan describes how the agency will build on its science-for-development agenda.

A six-country assessment shows how women's inclusion in science should be supported, write gender experts Sophia Huyer and Nancy Hafkin.

Developing countries deserve more support for their efforts to prioritise climate change in development, writes climate expert Simon Anderson.

The US development agency looks set to build on its 'development science' efforts during Barack Obama's second term, writes David Dickson.
