    A new route to chaos: Starting from a subharmonic frequency (the single peak), sidebands emerge as the control parameters is tuned (the modulated subharmonic state). Many frequencies form a very broad spectrum, which indicates chaos is being generated.

    FIGURE 1. Transforming bacteria into solar-powered lasers: we extract light-harvesting structures from bacteria (left), enhance them with proprietary specially engineered lasing units (middle), and place them into a lasing cavity (right) to create a new type of laser that runs directly on sunlight. The natural light-gathering rings (green/purple) of purple bacteria measure 60-nm across and achieve near-perfect efficiency in energy transfer of captured photons.
