Ultrafast plasmonics for all-optical switching and pulsed lasers

Plasmonics is playing a crucial role in advancing nanophotonics, as plasmonic structures exhibit a wide range of physical characteristics that are benefited by localized and intensified light-matter interactions. These properties ...

When the light is neither 'on' nor 'off' in the nanoworld

Whether the light in our living spaces is on or off can be regulated in everyday life simply by reaching for the light switch. However, when the space for the light is shrunk to a few nanometers, quantum mechanical effects ...

Unprecedented videos show RNA switching 'on' and 'off'

Similar to a light switch, RNA switches (called riboswitches) determine which genes turn "on" and "off." Although this may seem like a simple process, the inner workings of these switches have confounded biologists for decades.
