Conservation: Mark of respect p402

A project that gives Congolese pygmies new ways to tell logging companies about the trees that are important to them, and their own radio station to discuss community issues, is really putting their interests on the map, says Michael Hopkin.

Biochemistry: Uncharted route for antibiotics p415

In their battle for survival, soil microorganisms produce a vast arsenal of toxic molecules. One such toxin contains a unique sequence of atoms, and its biosynthesis includes some unexpected steps.

Immunology: Narcissistic helpers p416

T helper-17 cells, which are involved in immune responses, arise from a pool of precursor cells. It emerges that their differentiation is partly mediated by the IL-21 protein, which originates from the helper cells themselves.

Astrobiology: Photosynthesis in watercolours p418

The spectrum of stellar radiation available to an organism is altered by the atmosphere and water on the planet it inhabits. Study of this relationship can outline the limits to photosynthesis.

Developmental biology: A ten per cent solution p420

In early embryos, a concentration gradient of the Bicoid protein affects pattern formation. Studies of living embryos reveal a surprising level of accuracy in the Bicoid gradient. But is it accurate enough?

Inflammatory disease: Assault on the guardian p421

In multiple sclerosis, the immune system attacks 'self' tissues. Ten years after the discovery of one target of this autoimmunity, work with mice identifies it as a guardian protein produced in response to inflammation.

Quantum computing: Powered by symmetry p422

Forces determine how particles move and behave. But so can symmetry, and exchange symmetry can be used to control the interactions of ultracold atoms. This could be a big step towards practical quantum computation.

Immunology: Sensing the enemy within p423

Damaged or foreign DNA stimulates immune responses by inducing the production of interferon proteins. New evidence indicates that this response is mediated by a cytosolic DNA sensor known as DAI.
