The figure in the foreground shows near-infrared and broadband light pulses (squiggly lines at top) striking a silver nanocube measuring 150 nanometers square. The near-infrared pulse excites electrons in the nanostructure, while the broadband pulse monitors their optical response. An aluminum oxide spacer separates the nanocube from a gold film with a thickness of 50 nanometers. The spacer measures between 1 and 25 nanometers thick. A water molecule, by comparison, is approximately 1.5 nanometers in diameter. (Image courtesy of Matthew Sykes, Argonne National Laboratory, Shutterstock / Triff and Shutterstock / siro46.)
‘Hot’ electrons heat up solar energy research

A 3-D rendering shows simulated solar convection realized at different rotation rates. Regions of upflow and downflow are rendered in red and blue, respectively. As rotational influence increases from left (non-rotating) to right (rapidly rotating), convective patterns become increasingly more organized and elongated. Understanding the sun's location along this spectrum represents a major step toward understanding how it sustains a magnetic field.
