The Earth's climate is changing; but what are we doing about it? The frustration felt all around the world at the inability to agree a meaningful deal on global carbon dioxide emission leaves people looking for alternatives. Do we have the ability to manipulate our planet's climate to prevent the effects of global warming? If so how? What would be the consequences of attempting to do so? Understanding the physics of the Earth's climate is essential to answering these questions. Using the state-of-the-art computing power we are improving our knowledge of how the Earth works and of what any attempts to manipulate our climate would mean for the world we live in today...

David LLoyd describes how x-rays can be used for far more than identifying broken bones. From tracking the motion of electron to imaging the structure of viruses, he illustrates some examples of how researchers are using new x-ray sources to explore the microscopic world.

Since the discovery of the first extra-solar planet in the '90s, our perspective of the Universe has changed. Over the last two decades a whole host of exotic planet systems have been found, including analogues of famous science-fiction-worlds.
