Editorial
Who'd want to work in a team? p1
Biologists and their institutions are increasingly confronted by the challenges of working in major collaborations that other disciplines have already addressed. A gathering last week showed how much further there is to go.

Tropical diseases: Raiding the medicine cabinet p10
Many candidate drugs to fight diseases in the developing world have been shelved before approval — until now. Enter a medical charity that made its name by bringing hope to the world's disaster zones. Declan Butler reports.

Mathematics: Does the proof stack up? p12
Think peer review takes too long? One mathematician has waited four years to have his paper refereed, only to hear that the exhausted reviewers can't be certain whether his proof is correct. George Szpiro investigates.

Good to CU p21
A powerful arm of the cellular defence against microbial invaders has been characterized. APOBEC3G, a protein that can fight off HIV, works by introducing 'typographical errors' during viral replication.

Planetary science: The history of air p22
Giant impacts on Earth destroyed the envelope of gases surrounding the fledgling planet — so how has the modern-day planet regained its atmosphere? The answer, it seems, is that all was not lost.

Evolutionary biology: Polygamy and parenting p23
In most animal groups, females put more effort into rearing children, and males compete for female attention. But what about seahorses and pipefish, in which males invest the most in offspring?

Condensed-matter physics: Really cool molecules p24
Ultracold molecules have been made by applying a changing magnetic field to a quantum gas of 'fermionic' atoms. This raises the prospect of creating novel superfluids and molecular Bose–Einstein condensates.

Reproductive biology: Mammary messages p25
Identification of a pheromone that induces suckling in newborn rabbits sets a standard for studies on other mammals, and should prime investigations of the neurobiological basis of this behaviour.

Ecology: Roots of diversity p26
Competition between plants is in part responsible for the diversity of vegetation in different ecosystems. Diversity studies have to take into account what is happening beneath the soil as well as above it.

Astronomy: Heartbeats of a neutron star p27
Different oscillations in the flux of X-rays emitted from a neutron star now seem to be linked to the frequency at which the star is spinning. That spin rate in turn hints at what the interior of such a star is made of.

Ion channels: Hearing aid p28
Mechanically controlled ion channels — transduction channels — are a key feature of the cells that detect sound, touch and movement. In fruitfly ears, the channels belong to a very familiar group of proteins.
