Discussion needs to be open about how exploitation of Earth's internal heat can produce earthquakes, says Domenico Giardini, so that the alternative-energy technology can be properly utilized.
Seed banks must collect and condition their holdings of wild species so that they can thrive in landscapes transformed by climate change, say Jeffrey Walck and Kingsley Dixon.
In the second of two pieces on decarbonization, Isabel Galiana and Christopher Green argue that fostering a technology revolution, not setting emissions targets, is the key to stabilizing the climate.
In the first of two pieces on reducing greenhouse-gas emissions, Gert Jan Kramer and Martin Haigh analyse historic growth in energy systems to explain why deploying alternative technologies will be a long haul.
Lessons are still being learnt from the Antarctic Treaty, adopted 50 years ago this week. It set a visionary precedent for governing regions and resources beyond national jurisdictions, says Paul Arthur Berkman.
Latin Americans first saw evolution as a reason to 'whiten' their societies, then as a reason to take pride in their mixed lineage, says Jürgen Buchenau in the last of four pieces on Darwin's global influence.
To save biodiversity, on-the-ground agencies need to set the conservation research agenda, not distant academics and non-governmental organizations, argue Robert J. Smith and colleagues.
Natural ecosystems and biodiversity must be made a bulwark against climate change, not a casualty of it, argue Will R. Turner, Michael Oppenheimer and David S. Wilcove.
Palaeontologists must model the causes of biodiversity rather than simply cataloguing fossils, says Douglas Erwin, as they curate the only record of ecosystems undamaged by humans.
The value of biodiversity must be accounted for, says Pavan Sukhdev. It is time for governments to invest to secure the flow of nature's 'public goods'.
To reconcile solution-driven research and blue-skies thinking, academic institutions urgently need innovative collaborations and new funding models, says Indira V. Samarasekera.
In China, under the threat of Western imperialism, interpretations of Darwin's ideas paved the way for Marx, Lenin and Mao, argues James Pusey in the third in our series on reactions to evolutionary theory.
Darwin's idea of the 'struggle for existence' struck a chord with his fellow countrymen. But Russians rejected the alien metaphor, says Daniel Todes, in the second of four weekly pieces on reactions to evolutionary theory.
Forty years ago today the first message was sent between computers on the ARPANET. Vinton G. Cerf, who was a principal programmer on the project, reflects on how our online world was shaped by its innovative origins.
People from Egypt to Japan used Darwin's ideas to reinvent and reignite their core philosophies and religions, says Marwa Elshakry in the first of four weekly pieces on how evolution was received around the world.
Rajendra K. Pachauri says that India wants to be a constructive partner in Copenhagen negotiations on climate change. The country is taking domestic action even though it cannot accept mandatory emissions limits.
Google Wave is the kind of open-source online collaboration tool that should drive scientists to wire their research and publications into an interactive data web, says Cameron Neylon.
The 'Polymath Project' proved that many minds can work together to solve difficult mathematical problems. Timothy Gowers and Michael Nielsen reflect on the lessons learned for open-source science.
