Nature Magazine: Latest issue

Whats new in Nature Magazine: 17 April, Volume 452, Number 7189, pp781-912
* James Watson's genome sequenced at high speed p788
New-generation technology takes just four months and costs a fraction of old method.
* Novel analysis identifies highly biodiverse hotspots p789
New method plots Madagascar's species in unprecedented detail.
* Merck accused of disguising its role in research p791
Drug company used ghost-writers for papers published on Vioxx trials.
* $50 million cyberchallenge for plant scientists p793
iPlant Collaborative offers prize for user-friendly computational tools.
* Germany eases ban on embryonic stem-cell lines p796
* Further reports announced by climate-change panel p796
* Mars moon in high resolution p797
News Features:
* Climate change: Losing greenland p798
Is the Arctic's biggest ice sheet in irreversible meltdown? And would we know if it were?
* 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.
* Malaria programmes need informed advocacy p810
News and Views:
* 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?
* Why fishing magnifies fluctuations in fish abundance p835
Christian N. K. Anderson, Chih-hao Hsieh, Stuart A. Sandin, Roger Hewitt, Anne Hollowed, John Beddington, Robert M. May & George Sugihara
* Evolvability and hierarchy in rewired bacterial gene networks p840
Mark Isalan, Caroline Lemerle, Konstantinos Michalodimitrakis, Carsten Horn, Pedro Beltrao, Emanuele Raineri, Mireia Garriga-Canut & Luis Serrano
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.
* Nanotechnology: When one cantilever is not enough p903
* Nanotechnology: Shrinking down gas chromatography p904
