Better climate data required p287
The global observing system provides the raw data climate research relies on. But the quality of the gathered data is patchy. The system needs improvement — on land and on sea.

Palaeontology: Turning over a new leaf p309
A model based on biophysical principles of plant physiology, and drawing on fossil and environmental data, indicates that the origin of leaves was triggered by falling levels of atmospheric CO2.

Astronomy: Brown dwarf is a radio star p310
Brown dwarfs are sometimes referred to as failed stars because they emit extremely little radiation. Astronomers have now found a brown dwarf that 'whistles' strongly at radio wavelengths.

Molecular clocks: A vivid loop of light p311
Studies of biological molecular clocks have benefited greatly from a unicellular fungus. The latest discovery is of a fungal protein required in resetting the clock in response to light.

Solar physics: Sizing up the Sun p313
Variations in sunspot activity affect the weather on Earth, but the underlying mechanisms are unknown. New measurements of the Sun's radius and luminosity may help pinpoint the source of the energy responsible.

Neurobiology: New memories from new neurons p314
Neurons are born throughout adulthood in specific regions of mammalian brains. It now turns out that — in rats at least — these new neurons are essential for the formation of one type of memory.

Biogeochemistry: Oxygenating the atmosphere p317
Photosynthesis is the main source of oxygen in Earth's atmosphere. But it may have been geological activity that first allowed an oxygen-rich atmosphere to develop.

Cognitive neuroscience: Repression revisited p319
The idea that unwanted memories can be repressed has been controversial. An adaptation of an old technique provides an unambiguous model for exploring memory repression in the laboratory.

Superconductivity: Magnetic glue exposed p320
Overcoming electrons' mutual repulsion is the key to superconductivity. In simple metals, the forces that bind these charged particles in pairs are well understood, but what is the glue in other superconductors?

Structural biology: Protein crystal mimics reality p321
Flagellin, a protein in the bacterial flagellar motor, has resisted attempts at three-dimensional crystallization — until now. The crystal structure offers hints as to how filaments are able to switch helical states.
