If North Korea is to bid farewell to nuclear arms, negotiators will have to convince the country that its neighbours do not themselves want to become nuclear powers. Recent activities in Japan and South Korea will make this harder.
There are worse places to do research, but for the Caribbean cruise ship Explorer of the Seas, home to two climate laboratories, it's not all smooth sailing. Emma Marris finds out why.
Enzymes are well known for speeding up reactions. But have they evolved to use quantum mechanics to exert their effects? Philip Ball meets the researchers who are trying to find out.
A statistical study shows convincingly that a technique for marking frogs in ecological field experiments compromises the results. Present practices need a rethink — and not only for practical reasons.
Molecules ionize and fragment when subjected to energetic radiation. The behaviour of a simple molecule, deuterium, can now be tracked through this process in greater detail than ever before.
The NF-κB protein is a key player in inflammation. It now seems that it might also activate signalling pathways, in both cancer cells and tumour-associated inflammatory cells, that promote malignancy.
Vast amounts of carbon are locked into soils at northern high latitudes. The vexed question of how these ecosystems will respond to global warming is addressed by a long-term experiment in the Arctic.
Studies of a bacterial virus have revealed an unexpected weapon that helps it to overcome its host's rapidly changing defences. A look at other organisms hints that the mechanism might be widespread.
There are various techniques for the restoration of artwork — how effective and safe these are also varies. ‘Reversible’ gels could, however, provide a less risky way to reverse the ravages of time.
Could Spain kick off its legacy of inertia and win as much fame for research as for football? It's backing some of its star players with schemes to promote fresh talent, says Quirin Schiermeier.
