* Quantum computation: The dreamweaver's abacus p803
Some experts think that a quantum computation could be plaited like a skein of string. And now they may have found the sorts of string they need, finds Liesbeth Venema.

* Human genetics: Dr Watson's base pairs p819
The application of new technology to sequence the genome of an individual yields few biological insights. Nonetheless, the feat heralds an era of 'personal genomics' based on cheap sequencing.

* Biophysics: The sweetest candy for the virus p822
For some viruses, the first step in infecting cells is to latch onto sugars on the cell membrane. The chemical basis of this virus-host recognition process has been identified using an NMR spectroscopic technique.

* Quantum physics: Debut of the quarter electron p822
A particle-like object with a quarter of an electron's charge is the latest find in a hotbed of quantum-physical experimentation, the fractional quantum Hall fluid. Its significance is more than esoteric.

* Systems biology: Genome rewired p824
Within a genome, genes are connected to each other through a complex network of interactions. One way to assess how robust and evolvable such genomic networks are is to introduce new links between unrelated genes.

* Ecology: Destabilized fish stocks p825
Fishing of natural populations increases the variability of fish abundance. A unique data set from the southern California Current has allowed an evaluation of three hypotheses for why that should be so.

* Astrophysics: Blown away by cosmic rays p826
X-ray data reveal that our Galaxy is shedding part of its gas, a phenomenon previously associated only with much more active star-forming galaxies. So what is driving the process in the Milky Way?

Technology Features:
* Nanotechnology: Could it be a small world after all? p901
Sophisticated technologies can now explore nano-scale forces and interactions. But most biologists are staying on the sidelines, waiting to see if these technologies can really help them. Nathan Blow reports.
