Semiconductor electronics: Trapped fast at the gate p268
The speed record for programming organic transistor memory has been shattered. Work is needed on the stability of the memory storage, but it's a promising step towards some novel technological applications.

Climate change: Lessons from a distant monsoon p270
The burden of global warming falls most heavily on the developing world. A connection forged between the Indian Ocean climate, Asian monsoons and drought in Indonesia makes for an especially bleak outlook for that nation.

Polymer chemistry: Sacrificial synthesis p271
The size and uniformity of polymer molecules makes it difficult to modify them at just one selected site. But a single chemical group can be attached at the end of a polymer if part of the starting material is forfeited.

Cell biology: A switch for S phase p272
DNA replication is a necessary prelude to the division of a eukaryotic cell. Initiation of this process requires a complex script, involving many proteins: details of one of the main acts now emerge.

Cosmology: The Universe's skeleton sketched p273
The deepest and clearest maps yet of the Universe's skeleton of dark-matter structure present a picture broadly in concord with favoured models — although puzzling discrepancies remain.
