Tight US customs controls on microbiological materials could threaten foreign research collaborations. Especially at risk are attempts to integrate Russia's former bioweapons scientists into the mainstream.

Russia's bioweapons labs: Still out in the cold p678
Collaborations between Western researchers and former Soviet bioweapons scientists could benefit both parties. But mistrust and bureaucracy are getting in the way, says Geoff Brumfiel.

Rapid climate change: Gas leak! p681
Global warming isn't a new phenomenon — sea-bed emissions of methane caused temperatures to soar in our geological past. But no one is sure what triggered the release. Quirin Schiermeier investigates.

隕石学：タイミングに疑問
Meteoritics: A question of timing p691
Meteorites record the early history of the inner Solar System. A unique object that has been found in one meteorite may add support to a revolutionary idea about how the Solar System formed.

ヒトの進化：エチオピア出土の化石
Human evolution: Out of Ethiopia p692
Newly discovered fossils from Ethiopia provide fresh evidence for the 'out of Africa' model for the origin of modern humans, and raise new questions about the precise pattern of human evolution.

高エネルギー物理学：5次元へ
High-energy physics: Into the fifth dimension p695
Particles such as the proton can be imagined as vibrating strings. We also know that protons contain smaller, point-like particles, going against the string theory. But in five dimensions, the contradiction disappears.

認知神経科学：練習しても完璧は得られない
Cognitive neuroscience: Practice doesn't make perfect p696
It may seem counterintuitive, but we are not very efficient at recognizing even the most common words. This finding suggests strict limits on how flexible we are in learning to recognize new patterns.

宇宙物理学：表面の共鳴
Astrophysics: Superficial resonance p697
Neutron stars are the most poorly understood stellar objects in the Universe. But observations of X-rays emitted from one neutron star have now revealed a clue to the nature of its surface and composition.

進化生物学：新たな種を作り出す遺伝子
Evolutionary biology: Genes to make new species p699
A long-term goal of studies of the way in which new species form has been to identify the genes involved, and the forces that drive their evolution. That goal is now being realized — and natural selection plays a major part.
