Perfecting digital imaging
Despite advances, the best software and video cameras cannot seem to get computer-generated images and digital film to look exactly the way our eyes expect them to. Harvard’s Hanspeter Pfister and Todd Zickler are working to narrow the gap between “virtual” and “real” by asking the question: How do we see what we see?

Nanoparticles shine with customizable color
Engineers at Harvard have demonstrated a new kind of tunable color filter that uses optical nanoantennas to obtain precise control of color output. The advance has the potential for application in televisions and biological imaging, and could even be used to create invisible security tags to mark currency.

A living laser
In a new report, Harvard researchers Malte Gather and Seok-Hyun Yun describe how a single cell genetically engineered to express green fluorescent protein can be used to amplify the light particles called photons into nanosecond-long pulses of laser light.
