The attoclock, illustrated here, can measure laser pulses that last billionths of a billionth of a second long.

Holograms at the Nanoscale: New Imaging for Nature¹s Tiniest Structures

Organic semiconductors hold immense promise for use in thin film and flexible displays – picture an iPad you can roll up – but they haven’t yet reached the speeds needed to drive high definition displays.

In repeatedly and systematically surveying the sky with deep, large-field-of-view images in six optical color bands on a 3 billion pixel camera for years, the Large Synoptic Survey Telescope will home in on the nature of dark energy and increase...
