Science and law: Biotechnology at the bar p116
Science is moving too fast for the legal system to keep up. But lawyers and scientists have a solution — a body that would help courts tackle cases involving the latest research. Nicola Nosengo investigates.

Drug research: The ups and downs of lithium p118
Lithium has been used to treat manic depression for decades, and may help combat other brain disorders. So how come no one knows for sure why it works? Helen R. Pilcher reports.

Planetary science: Spin control for asteroids p131
Random collisions between asteroids would seem to cause their spin axes to be tilted in all directions. Surprisingly, the gentle recoil force of thermal re-radiation may bring their spin axes into alignment.

Ageing: A toast to long life p132
Reducing food intake increases lifespan in many species. A small molecule that occurs naturally in plants seems to mimic the beneficial effects of caloric restriction and extend longevity in yeast.

Condensed-matter physics: Vortices and hearts p133
A single vortex of flux, formed inside a superconducting Josephson junction, has been detected undergoing quantum tunnelling — a feature that could be developed into a quantum bit.

Behavioural ecology: Father knows best p136
When females mate with several males, paternity may be uncertain. But male savannah baboons are seldom confused: when intervening in fights between youngsters, they generally support their own offspring.

Cosmochemistry: Inside the cosmic blender p137
The Solar System has a largely uniform isotopic composition but with tantalizing small variations. Geochemists are trying to ascertain the mechanisms and types of stars that produced this state of affairs.

Cardiovascular biology: Signalling silenced p139
The mechanism by which the TIMP-2 protein inhibits blood-vessel formation has been uncovered — and it is not as expected. The finding has implications for treating a cancer by cutting off its blood supply.
