Neuroscience: Feel the light pp900 - 901
How is light perceived? The answer that might immediately come to mind is, through the eyes. Fly larvae, however, can 'feel' light using specialized neurons embedded under the cuticle encasing their bodies. See Articlep.921

Astrophysics: A strange ménage à trois pp901 - 902
The two Magellanic Clouds may have joined our Milky Way quite recently. It turns out that this trio of galaxies is remarkably unlike most other galaxy systems — both in the luminosity of the clouds and in their proximity to the Milky Way.

Drug discovery: How melanomas bypass new therapy pp902 - 903
The promise of an exciting new drug that inhibits the mutant B-RAF protein in skin cancer is marred by the fact that most patients relapse within a year. Fresh data hint at how such resistance emerges. See Lettersp.968 & p.973
David Solit and Charles L. Sawyers

Solar system: Recipe for making Saturn's rings pp903 - 905
Simulations show that the still-mysterious origin of Saturn's vast, icy rings could be explained by the 'peeling' by Saturn's tides of the icy mantle of a large satellite migrating towards the planet. See Letterp.943
Aurélien Crida and Sébastien Charnoz
doi:10.1038/nature09738

Climate change: The prospects for polar bears pp905 - 906
Is the polar bear doomed to extinction? Maybe not, according to models of the future extent of Arctic sea ice if greenhouse-gas emissions are curbed. The outlook depends on the ability of policy-makers to act. See Letterp.955

Materials science: Pleated crystals pp906 - 907
A neat study that involves placing colloidal particles on curved oil- glycerol interfaces reveals a new form of crystal defect. The defect is called a pleat, by analogy to the age-old type of fabric fold. See Letterp.947
