Drug discovery: In the eye of the beholder p990
Does the pharmaceutical industry's future lie at the boundary between drugs and cosmetics? Or is the prospect of effective 'cosmeceuticals' a beauty myth? Helen Pearson investigates.

Arctic research: Summer in Svalbard p992
Scientists at one of the world's most remote research outposts are tracking the air masses that swirl through the Arctic atmosphere in an attempt to understand why the ozone layer continues to thin. Quirin Schiermeier visits the Koldewey research station.

Genome sequences from the sea p1001
Despite their diminutive stature, phytoplankton have a huge global influence. The genomes of four strains of phytoplankton have now been completely sequenced, revealing their genetic adaptations to distinct marine niches.

Turbulence: Suddenly it's chaos p1002
Injecting vortices into a rotating sample of superfluid helium-3 shows a sudden switch from smooth to chaotic behaviour, and throws light on turbulence — one of the last unsolved problems of classical physics.

Neuroscience: Of mice and mentality p1004
Evidence of a general learning ability in mice — that there is a good correlation between an individual's performance in tasks that make different processing demands — suggests a parallel with humans.

Mechanics: Friction in a spin p1005
The mechanics of friction may seem the stuff of high-school physics, but only now are some aspects of the problem being understood. A spinning coin is the subject of a new exploration of frictional forces.

Ecology: Tail of death and resurrection p1006
Estimating the proportion of rare species in particular habitats is a big issue for ecologists. Hence the intensity of debate over whether 'neutral theory' has predictive value for species abundances.

Quantum gravity: An astrophysical constraint p1007
A quantum theory of gravity is proving elusive. Observations of radiation from the Crab nebula now place even stronger constraints on the likelihood of detecting the effects of quantum gravity.

Mars: The devil is in the dust p1008
Mars is a highly dynamic planet — at least as far as dust is concerned. A better knowledge of how dust is lofted into the atmosphere will help to untangle the complex evolutionary history of the planet's surface.

Biomaterials: Silk's secrets p1010
Despite centuries of human use of silk fibres from silkworm cocoons, and an emerging industry devoted to making artificial silk, questions remain about how insects produce it. New work in vitro tackles the problem.
