Crystals of the material hexagonal boron nitride can be etched so that the pattern you draw at the top transforms into a smaller and razor-sharp version at the bottom. These perforations can be used as a shadow mask to draw components and circuits in graphene. This process enables a precision that is impossible with even the best lithographic techniques today. To the right are images of triangular and square holes taken with an electron microscope.

Researchers created two WGM microresonators with different absorption losses and coupled their optical fields by setting them close together. Each resonator is coupled to a fiber waveguide. By changing the gap between the resonators and waveguides, they were able to tune the coupling loss

An East European vole on Spitzbergen island. These animals were introduced to the Svalbard islands over a few decades. With no predators, their presence provides scientists with a living system to assess the impacts of predators on the populations cycles of small Arctic mammals.

Measuring 12 cms, the object that is to be made invisible acoustically is placed between two acrylic glass panels at the centre of the experiment. The initial acoustic field is produced by the loudspeakers in the outer ring. The 228 control sensors in the central ring record this field and transmit the data to a computer in the next room. Subsequently, 36 control sources in the centre emit a secondary signal that augments the initial field in real-time.
