  • A growing population, climate change and the environmental impacts of conventional agricultural practices are worsening food insecurity. New research shows that use of nanofertilizers can increase food production while simultaneously decreasing the negative environmental effects of agriculture.

  • A new study demonstrates that small synaptic vesicles exocytose dopamine through a flickering fusion pore almost exclusively, a process known as 'kiss-and-run' exocytosis. This process is driven by the need for efficient use of few synaptic vesicles.

  • Surface-enhanced Raman spectroscopy (SERS) uses nanostructured materials to enhance the Raman scattering of a sample, enhancing sensitivity and allowing analysis of materials in low concentration. In this Primer, Han et al. detail the use of SERS equipment and preparation of SERS-active materials, as well as recent applications in biological and chemical sciences.

  • Superfluidity, a liquid exhibiting frictionless flow, is so far limited to observations in low-temperature 3He and 4He, where the underlying mechanisms governing the quantum state are complex and different for each isotope, making for a fascinating but challenging phenomenon to study experimentally. The authors use isotope-sensitive neutron reflectometry to investigate mixed 3He/4He superfluid He films on a Si surface, and resolve the structural features and phase transitions that occur with changing temperature.
