... Molecular Cell. Details gleaned from an in-depth look at a protein found in tuberculosis bacteria suggest that the protein can be disabled when it binds to certain other molecules. With this protein sidelined, tuberculosis bacteria become more sensitive to treatment by a "second-line" drug called ethion...UF scientist: 'Brain' in a dish acts as autopilot, living computer
