Single-Cell Imaging Clarifies How Cells Tell Time

Facebook X LinkedIn Email
COLUMBUS, Ohio, and MONTREAL, Nov. 19, 2012 — A new imaging approach offers the first real-time visual evidence of how cells know when to enter the next phase of their development. As they develop, embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of molecular “clock,” but just how this timing system works has been unclear. An international cross-disciplinary collaboration between physicists and molecular genetics researchers from Ohio State and McGill universities sheds light on the clock mechanism by...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
