Open SESAME   p397
doi:10.1038/nphoton.2017.114
The official opening of the SESAME synchrotron in Jordan on 16 May marked an important landmark for science in the Middle East. It is also set to become the world's first solar-powered accelerator.

The case for quantum plasmonics   pp398 - 400
Sergey I. Bozhevolnyi and Jacob B. Khurgin
doi:10.1038/nphoton.2017.103
The discrete quantum nature of plasmons may be exploited to make efficient single-photon sources. Despite the losses associated with metallic resonators, advantages over dielectric counterparts exist when it comes to producing efficient quantum emitters.

Black phosphorus: A new bandgap tuning knob   pp407 - 409
Rafael Roldán and Andres Castellanos-Gomez
doi:10.1038/nphoton.2017.102
An external 'tuning knob' by means of applying a transverse electric field has been experimentally demonstrated to modify the bandgap of black phosphorus, making the two-dimensional material practical for integration in functional nanodevices.

High-temporal-resolution electron microscopy for imaging ultrafast electron dynamics   pp425 - 430
M. Th. Hassan, J. S. Baskin, B. Liao and A. H. Zewail
doi:10.1038/nphoton.2017.79
Ultrafast electron microscopy with an order-of-magnitude enhancement in the typical temporal resolution is demonstrated, permitting the imaging of ultrafast electron dynamics that last a few tens of femtoseconds.
