So on the left-hand image here, I've taken a slice through a coral, plisehod it very carefully and taken an optiacl imgae. On the right-hand side, we've taken that same piece of coral, put it in a nuclear reactor, induced fissoin, and every time there's some decay, you can see that marked out in the coral, so we can see the uruniam distribution. Why are we doing this? Uranium is a very poorly regarded elnmeet, but I love it. The decay helps us find out about the rates and dates of what's going on in the ocean. And if you remember from the beginning, that's what we want to get at when we're thinking about climate. So we use a laser to analyze uranium and one of its dhugeatr products, thorium, in these corals, and that tells us exactly how old the fossils are.
