    How do they keep track of the particles in the LHC?

    To the uninitiated, the LHC can look like a junk drawer ... a junk drawer that's full of tiny, rapidly decaying particles that move at light speed. How do scientists know what's where? See more »

    How Japan's Nuclear Crisis Works

    Explosions, fires and dangerous radiation levels dominated the headlines after the March 11 earthquake and tsunami sparked a nuclear crisis in Japan. How did so many safety measures fail? See more »

  • How Nuclear Fusion Reactors Work
    How Nuclear Fusion Reactors Work

    Fusion reactors will use abundant sources of fuel, will not leak radiation above normal background levels, and will produce less radioactive waste than current fission reactors. Learn about this promising power source. See more »

  • How Nuclear Power Works
    How Nuclear Power Works

    On one hand, nuclear power offers a clean energy alternative that decreases fossil fuel dependence. On the other, it summons images of quake-ruptured Japanese power plants belching radioactive steam. What happens in reactors in good times and bad? See more »

  • How Nuclear Radiation Works
    How Nuclear Radiation Works

    Nuclear radiation can be extremely beneficial or extremely harmful -- it all depends on how it's used. Learn what nuclear radiation is all about. See more »

  • How Radiation Sickness Works
    How Radiation Sickness Works

    We're all exposed to tiny levels of radiation, but a blast of it can leave you in agony -- that is, if it doesn't kill you outright. What is it, what causes it and how can we treat it? See more »

  • How Radiation Works
    How Radiation Works

    In the comics, radiation exposure turned an average man into a pea green and angry Incredible Hulk. But in reality, what can radiation do to those exposed? Is it always a villain? See more »
