Animal behaviour: The lobster navigators p27

When experimentally displaced in geomagnetic space, spiny lobsters act as if to make their way home. This is a fascinating case of navigation by an invertebrate using a magnetic map sense.

Planetary science: Sodium at Io p30

It has been known for some years that Jupiter's satellite Io has sodium as a component of its atmosphere. The source, it now seems, is sodium chloride emitted by volcanoes on Io's surface.

Molecular evolution: Duplication, duplication p31

Duplicated genes are common in genomes, perhaps because they provide redundancy: if one copy is inactivated, the other can still work. A new study quantifies the effects of deleting 'singletons' and duplicated genes in yeast.
