No consensus on stem cells p587
Problems with reproducibility bedevil research on adult stem cells, yet treatments using the cells are moving rapidly into human clinical trials. Those working in the field need to adopt more robust experimental approaches.

True colours p596
It's only when you begin to see the world as birds do — detecting light in the ultraviolet spectrum — that the full subtlety of their behaviour is revealed. Rex Dalton catches a glimpse.

Stem cells: Lost in translation p607
The potential use of stem cells as agents of repair in human disease makes them the subject of high-profile studies. But we should be wary of prematurely pushing laboratory research into clinical practice.

Earth science: Time of reversal p608
At intervals, the polarity of the Earth's magnetic field reverses. The timescale for this reversal is unclear — in fact, it seems to depend on the latitude of the site from which the geological data are extracted.

Mars: Water, water everywhere p610
Mars is a very watery planet, but all the water seems to be frozen. Divining the amount and distribution of this water, past and present, is essential for understanding martian climates, and more.

Behavioural evolution: Cooperate with thy neighbour? p611
What gives cooperation an evolutionary edge? Two features of a population — spatial structure and finite size — are factors in the success of any strategy, although more subtle than we thought.
