Periodic arrays of cone-shaped hexagonal boron nitride (hBN) nanoantennas, depicted magnified image above, were used to confine hyperbolic polaritons in all three dimensions. This enabled the researchers to fundamentally probe the novel optical properties within these materials and demonstrate the highly directional, low loss hyperbolic polaritons that are confined within the volume of the antennas. These results provide the first foray into natural hyperbolic materials as building blocks for nanophotonic devices in the mid-infrared to terahertz (THz) spectral range.

Shrimp called Rimicaris hybisae at deep hydrothermal vents in the Caribbean seem to have different dietary habits depending on the proximity of other shrimp. Those who live in dense clusters like this one live off bacteria primarily, but in areas where the shrimp are distributed more sparsely, the shrimp are more likely to turn carnivorous, and even eat each other.

The Baltic Sea Network is a multidisciplinary research project which will explore new biomedical applications for nanomaterials, for example in cancer treatment, for antimicrobial purposes, as bio-sensors or as a contrast agent for medical diagnostics. Participating universities and researchers hope that by promoting a free exchange of research and ideas, for example by making laboratories and facilities accessible to other project partners, they will encourage new research findings to the benefit of all participants. The project's ultimate goal, however, is to establish a new research platform focused on developing hybrid nanomaterials for biomaterial applications.

Researchers at Nano-Meta Technologies Inc. (NMTI) in the Purdue Research Park have shown how to overcome key limitations of a material that could enable the magnetic storage industry to achieve data-recording densities far beyond today's computers.
