Quantum information: To compute or not to compute?
Quantum physics aims another blow at common sense: a simple quantum computer
gives the right answer, even when it is not run. (Traditionalists be
comforted: the computer must be turned on.)
Jonathan P. Dowling
http://www.nature.com/nature/journal/v439/n7079/full/439919a.html

Neurobiology: Efficiency measures
The nervous system translates sensory information into electrical impulses.
The neural /`code/' involved seems to represent natural sounds and images
efficiently, using the smallest number of impulses.
Michael R. DeWeese and Anthony Zador
http://www.nature.com/nature/journal/v439/n7079/full/439920a.html

Particle physics: Quarks on a gravitational string
Quantum chromodynamics, the theory of the strong nuclear force, is
notoriously intractable. An alternative approach brings gravity to bear, and
produces fairly accurate predictions of some physical quantities.
Nick Evans
http://www.nature.com/nature/journal/v439/n7079/full/439921a.html

Evolution: Careful with that amphioxus
The textbook tale of vertebrate origins is brought into question by
phylogenetic analyses of new genomic data. But the amphioxus, long viewed as
a precursor to fish, remains a central character in events.
Henry Gee
http://www.nature.com/nature/journal/v439/n7079/full/439923a.html

Planetary science: Pluto's expanding brood
Pluto is no lone ranger in the farthest expanses of the Solar System [mdash]
its travelling companions now number three. And if Pluto can have so many,
why shouldn't other objects in the distant, icy Kuiper belt?
Richard P. Binzel

Marine biology: Spawning spot
Rosalind Cotter
http://www.nature.com/nature/journal/v439/n7079/full/439926a.html

Parasitology: Switching like for like
To remain hidden from its host's immune system, the malaria parasite must
vary the proteins on the surface of the infected cell. The genes encoding
these proteins are very similar, so how does the parasite express just one
at a time?
