Dig deeper pp448 - 450 Paul Newman and Anna Stasto doi:10.1038/nphys2718 Deep inelastic scattering — using a twenty-first-century electron-hadron collider of sufficient energy and intensity — could teach us much more about nuclear matter at the smallest resolvable scales, as well as add to our understanding of the Higgs boson and to the search for physics beyond the standard model.

Self-organized criticality in X-ray flares of gamma-ray-burst afterglows pp465 - 467 F. Y. Wang and Z. G. Dai doi:10.1038/nphys2670 Gamma-ray bursts are the most energetic sources of radiation in the Universe, and half are followed by afterglows that include X-ray flares of mysterious origin. A statistical study of such X-ray flares reveals the same power-law behaviour as solar flares, which suggests a common underlying magnetic reconnection process.

Imaging Cooper pairing of heavy fermions in CeCoIn5 pp468 - 473 M. P. Allan, F. Massee, D. K. Morr, J. Van Dyke, A. W. Rost et al. doi:10.1038/nphys2671 By pushing scanning tunnelling spectroscopy down to millikelvin temperatures, it is now possible to image a heavy fermion superconductor and measure the superconducting gap symmetry, with gap nodes in unexpected momentum-space locations.

Visualizing nodal heavy fermion superconductivity in CeCoIn5 pp474 - 479 Brian B. Zhou, Shashank Misra, Eduardo H. da Silva Neto, Pegor Aynajian, Ryan E. Baumbach et al. doi:10.1038/nphys2672 By means of low-temperature scanning tunnelling spectroscopy, a heavy fermion material in its superconducting and mixed states can be imaged. Besides probing the superconducting gap symmetry, the measurements also reveal a pseudogap.

Coherent phonon manipulation in coupled mechanical resonators pp480 - 484 Hajime Okamoto, Adrien Gourgout, Chia-Yuan Chang, Koji Onomitsu, Imran Mahboob et al. doi:10.1038/nphys2665 It is now shown that phonons can be coherently transferred between two nanomechanical resonators. The technique of controlling the coupling between nanoscale oscillators using a piezoelectric transducer is useful for manipulating classical oscillations, but if extended to the quantum regime it could also enable entanglement of macroscopic mechanical objects.

Coherent control of a classical nanomechanical two-level system pp485 - 488 T. Faust, J. Rieger, M. J. Seitner, J. P. Kotthaus and E. M. Weig doi:10.1038/nphys2666 Coherent control of two flexural modes of a nanoscale oscillator using radiofrequency signals is now demonstrated. This oscillator is analogous to quantum two-level systems such as superconducting circuits and quantum dots, and therefore this technique raises the possibility of information processing using nanomechanical resonators.

Imaging coronal magnetic-field reconnection in a solar flare pp489 - 493 Yang Su, Astrid M. Veronig, Gordon D. Holman, Brian R. Dennis, Tongjiang Wang et al. doi:10.1038/nphys2675 Extreme ultraviolet and X-ray imaging of a solar flare with unprecedented clarity now provide visual evidence that magnetic reconnection plays a fundamental role in generating solar flares. The Atmospheric Imaging Assembly on NASA's Solar Dynamics Observatory is able to observe a 'cold' plasma moving into the reconnection point and the simultaneous acceleration of a hot-flare-heated plasma away from it.

Bacteria can exploit a flagellar buckling instability to change direction pp494 - 498 Kwangmin Son, Jeffrey S. Guasto and Roman Stocker doi:10.1038/nphys2676 Buckling is often regarding as a form of mechanical failure to be avoided. High-speed video microscopy and mechanical stability theory now show, however, that bacteria use such processes to their advantage. Cells propelled with a single flagellum change direction with a flick-like motion that exploits a buckling instability.

Mapping the orbital wavefunction of the surface states in three-dimensional topological insulators pp499 - 504 Yue Cao, J. A. Waugh, X-W. Zhang, J-W. Luo, Q. Wang et al. doi:10.1038/nphys2685 In topological insulators, studies have largely concentrated on the spin part of the wavefunction. But the spin-orbit coupling is strong, so the orbital components of the wavefunction need to be measured as well. Surprisingly, the orbital wavefunction turns out to be asymmetric about the Dirac point.

Domain wall trajectory determined by its fractional topological edge defects pp505 - 511 Aakash Pushp, Timothy Phung, Charles Rettner, Brian P. Hughes, See-Hun Yang et al. doi:10.1038/nphys2669 When a domain wall of a given chirality is injected into a magnetic nanowire, its trajectory through a branched network of Y-shaped nanowire junctions—such as a honeycomb lattice, for instance—can be pre-determined. This property has implications for data storage and processing.

Population distribution of product states following three-body recombination in an ultracold atomic gas pp512 - 517 A. Härter, A. Krükow, M. Deiß, B. Drews, E. Tiemann et al. doi:10.1038/nphys2661 Atom and ion trapping provides new tools for ultracold chemistry. Using these techniques it is possible to measure the population distribution of the product states of three-body recombination in an ultracold atomic gas.

Capturing photons with transformation optics pp518 - 522 J. B. Pendry, A. I. Fernández-Domínguez, Yu Luo and Rongkuo Zhao doi:10.1038/nphys2667 The modelling of plasmonic systems is complicated by the broad range of length scales involved: the physical dimensions of the structure might be as small as 1 nm, whereas the wavelength of the light involved can be a few hundred nanometres. It is now shown that transformation optics, a technique successfully used to design metamaterials, is also valuable for circumventing these problems.
