Commentary
Scientists behaving badly p737
To protect the integrity of science, we must look beyond falsification, fabrication and plagiarism, to a wider range of questionable research practices, argue Brian C. Martinson, Melissa S. Anderson and Raymond de Vries.

Physics, complexity and causality p743
Although the laws of physics explain much of the world around us, we still do not have a realistic description of causality in truly complex hierarchical structures.

Cancer genomics: Small RNAs with big impacts p745
Although they are tiny, microRNAs can have large-scale effects because they regulate a variety of genes. These minuscule molecules are now definitively linked to the development of cancer.

Organic chemistry: Fast reactions 'on water' p746
Efficient reactions in aqueous organic chemistry do not require soluble reactants, as had been thought. A newly developed 'on-water' protocol is characterized by short reaction times, and the products are easy to isolate.

Planetary science: Shades of Titan p749
Instruments aboard the Cassini spacecraft can 'see' through the dense atmosphere of Titan, Saturn's largest moon. Returned images hint at the existence of features such as ridges and valleys, and perhaps an icy volcano.

Plant−fungal associations: Cue for the branching connection p750
Plant roots release potent molecules that activate symbiotic fungi and initiate a harmonious relationship. It turns out that the same compounds are detected by parasitic weeds for less benign purposes.

Computational science: Can get satisfaction p751
The sheer complexity of some computational problems means they will probably never be solved, despite the ever-increasing resources available. But we can sometimes predict under what conditions solutions exist.

Cancer: Inflammation by remote control p752
Smouldering beneath many latent tumours is a chronic inflammation that goads pre-malignant cells into becoming full-blown cancer. The spark that kindles these flames comes from an unexpected source.
