    Seeing things in a different light

    Harvard researchers are using a chemical process known as triplet fusion upconversion to transform near-infrared photons into high-energy photons. The high-energy photons could be used in a huge range of applications, including a new type of precisely targeted chemotherapy, in which low-energy infrared lasers that penetrate deep into the body could be used to transform…

    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.
