    Study Finds: Scientists Built Cancer Kill Switch That Turns On With Flash Of Light
    Photonics influences cell behavior by using light. Technocrats have discovered that many cells, or genetically modified cells, express light-sensitive proteins (opsins, rhodopsins) that open or close ion channels when illuminated, changing membrane potential and firing patterns. In neurons, this directly controls excitability, synaptic transmission, and network dynamics on millisecond timescales. ⁃ Patrick Wood, Editor.Cancer has a dirty trick: it can put itself to sleep.
