Anthrax: A molecular full nelson p373
The crystal structure of the final component of the three-part anthrax toxin shows how it disables a host signalling molecule, while simultaneously using that molecule to stimulate its own activity.

Extragalactic astronomy: Cosmic censorship p374
Cosmologists believe the Universe will expand forever, but our powers to observe it will not accelerate at the same rate. What does this mean for the future of astronomy?

Huntington's disease: Accomplices to neuronal death p377
The shaky movements of people with Huntington's disease are caused by death of a specific group of nerve cells. One culprit — the mutant huntingtin protein — is well known. Another has now been discovered.

High-temperature superconductivity: Quantum salad dressing p379
The mystery of how electrons in a high-temperature superconductor flow without resistance grows deeper. New pictures at the atomic scale reveal two electronic phases that — like oil and vinegar — do not easily mix.

Nitrogen cycle: Natural organic tendency p381
Dissolved nitrogen is usually thought to be transported from land to sea in inorganic form. But the predominance of organic nitrogen in streams in temperate South America suggests that this view needs a rethink.

Cell biology: Protein sweetener p382
After years of failure, a protein involved in flipping certain oligosaccharide molecules into the endoplasmic reticulum — one of the cellular sites where proteins are modified with sugars — has been tracked down.

Daedalus: Electric air drier p383
Most plastic films have long polymer molecules that lie in the plane of the film. A film with its molecules oriented perpendicular to the plane would be highly porous making it suitable for some novel applications.
