Editorials
Retractions' realities p1
The papers are published, the news is out, the kudos is gathered, the gasps of admiration over. But the results are wrong. What happens next?

Yes, we have no energy policy p1
A plan to generate electricity from coal without emitting greenhouse gas is as threadbare as the rest of Bush's energy policy.

Archaeology: The coast road p10
America's first inhabitants were people from Asia who migrated over a now-submerged land bridge between the two continents. But when did they come, and where did they go after making their crossing? Rex Dalton reports.

Crime prevention: The lab arm of the law p13
Forensic science is already a mainstay of modern police work. But are criminologists missing a trick by failing to apply the latest scientific findings to crime prevention? Jim Giles investigates.

News and Views
Evolutionary biology: Speciation reversal p25
Chromosome rearrangements within species are thought to contribute to reproductive isolation between species. This has now been shown directly by unrearranging yeast chromosomes to break down a species barrier.

Cosmology: Filling in the background p26
Data from NASA's Wilkinson Microwave Anisotropy Probe reveal the cosmic microwave background in more detail than ever before. But will cosmology become a victim of its own success?

Immunology: Fast and feel good? p27
Claims that fasting eases symptoms of autoimmune disease have been met with scepticism. But the idea receives some support from the finding that leptin, a hormone that controls body weight, also regulates autoimmunity.

Microfluidics: DNA amplification moves on p28
The polymerase chain reaction is widely used to amplify samples of DNA for genetic analysis, and fast, high throughput is the ideal. Microscale, chip-based devices are now proving themselves in this arena.

Planetary science: Kuiper-belt interlopers p30
Objects in the Kuiper belt, which lies beyond Neptune, occur as two distinct populations. One group may have migrated from a region closer to the Sun, caught by Neptune's gravity as it wandered in the early Solar System.

Plant biology: Mobile plastid genes p31
The direct demonstration that chloroplast DNA can be incorporated into the nuclear genome of plants, even though it is unlikely that such DNA would be functional, will influence thinking in plant biotechnology.

Access delayed p96
Tight new security measures aimed at preventing terrorism mean that postdocs and students travelling to the United States need to make plans a long way in advance and expect delays, says Karen Kreeger.
