Aspirin is not only an important drug, but also an interesting physics model system in which molecular vibrations and electrons are coupled in a particular way.  In a new method, materials scientists Boliang Jia and colleagues at the departments of mechanical engineering and robotics presented a printable biocompatible superlens placed directly on objects of interest to observe subdiffraction-limited features (resolution beyond the diffraction limit).  Physicists have also devised photonic topological insulators, synthetic materials that impart light waves with distinct topological features, allowing light (rather than electric currents) to flow via topological surface states.
