    The imaging of magnetic domains in three-dimensional solids has been hampered by a lack of suitable methods. The authors show that Talbot-Lau neutron tomography is capable of visualizing the domain structure of an iron silicide bulk crystal.

    The development of optical information processing depends on the demonstration of silicon-based all-optical circuit components. Here, the authors show a monolithic pulse compressor, compatible with current electronic processing technologies, which is able to function at low power input.

    The integration of oxide nanoelectronics with silicon platforms is a necessary step for the fabrication of ultrahigh-density devices. Here, the authors grow a LaAlO3/SrTiO3interface directly on silicon, and show the reversible creation of a two-dimensional electron gas confined within nanowires located on the surface.

    Protein interactions in biological environments are expected to differ from the situationin vitro. In this study, a thermophoresis-based technique is described that allows the analysis of protein and small-molecule interactions in biological liquids; the work may allow more efficient drug development.

    Flicker noise in nanoscale field effect transistors deviates from the simple frequency-dependent behaviour of macroscale objects. Here the authors show that Coulomb repulsion between nearby trap sites leads to an order of magnitude reduction in noise in these devices.

    The challenge of reconstructing the image of an object when viewed through an opaque material is of particular importance for biological tissues. Here, the authors show that it is possible to reconstruct the image of a complex object from interference patterns of multiple wavefronts using phase-shifting interferometry.

    The phase of a laser pulse is usually random, which prevents its use for phase-resolved measurements. Here, the authors seed a quantum cascade laser with coherent terahertz pulses, forcing laser action to start on a fixed phase. This kind of laser could be used as a source in time-domain spectroscopy.

    One reason for using photonic devices is their speed—much faster than electronic circuits—but there are many challenges in integrating the two technologies. Ferreraet al. construct a CMOS-compatible monolithic optical waveform integrator, a key building block for photonic circuits.

    Optical cloaking has already been demonstrated in two dimensions, and also in three dimensions for a limited range of angles. Now, Ma and Cui present a metamaterial-based cloaking device that can shield an object lying on the ground plane from all viewing angles at microwave frequencies.
