Editorial
Leapfrogging the power grid p661
The desire to mitigate climate change, and opportunities to empower consumers in the developed and developing worlds, all point towards a need for less-centralized energy generation. It's time to further boost hydrogen research.

Science at the movies: The fabulous fish guy p672
Last year's movie smash Finding Nemo impressed many marine biologists with its scientific accuracy. Alison Abbott meets the young expert in fish biomechanics who helped to breathe life into the film's stars.
Origins of life: Born in a watery commune p674
If you go back far enough, humans, frogs, bacteria and slime moulds share a common ancestor. But scientists can't agree what it was like, or even whether it was a single creature. John Whitfield reviews the evidence.

Neuroscience: Immigration denied p685
The adult human brain cannot replace lost neurons. This might be because it is reluctant to accept newcomers into an already established neural network, rather than because potential progenitors are absent.

Palaeoclimate: Low-down on a rhythmic high p686
Changes in the amount of solar energy reaching Earth account for certain climate cycles at high and low latitudes. Surprisingly, the effects of a high-latitude cycle evidently reached into the tropics.
Katharina Billups
Transcription: Origins of licensing control p687
Organ development requires precise regulation of both the total number and the different types of cells. Much is known about how each process is controlled, but new light has been shed on how the two are linked.
Xue Li & Michael G. Rosenfeld
Particle physics: Two is the magic number p688
In quantum theory, the magnetic moment of the muon should be twice the value calculated classically, although in fact their ratio is not exactly two. Theory and experiment disagree on quite how far from two it is.

Malaria: A changed climate in Africa? p690
The rise of malaria in Africa is a subject of much debate. A new analysis emphasizes the influence of rainfall, but there appear to be few areas where climate has been a major driver of this change.
