 Features The final frontierIn the 1960s the space race created a fascination with science and great technological advances. To find alien life we need to take back up that mantle, says astrophysicist Stephen Hawking, and send people further into space.  Mirror imageDon't be mistaken, this is no Space Shuttle. This is the Buran, product of Soviet suspicion, ingenuity and scant funds; and doomed to failure.  Time warpIt can fly or it can crawl and it waits for no man.

But it seems that in science, as in nature, there are some places we still can't reach.  The technology of athletics tracksThough the high-tech swimsuits being used in the 2008 Beijing Olympics are getting most of the press, research shows that applying advanced technology to running tracks might help break records too.  China's Olympian efforts to tackle pollutionAs the 2008 Beijing Olympic Games get underway, an expensive environmental experiment is taking place, providing a golden opportunity for pollution science.  Cosmic rouletteAs physicists around the world are staking the lot on the Large Hadron Collider, we review the odds of success.  Solar sailingSolar sails would allow a spacecraft to be propelled by the gentle pressure of light itself. It sounds like a fantastical concept, but with two missions imminently due to practically test the idea, it's edging towards reality.  Silent springDeep in the radioactive bowels of the smashed Chernobyl reactor, a strange new lifeform is blooming.  Mapping the evolution of the cosmosA new telescope in the Australian outback, promises to answer big questions about the history and fate of the cosmos. By focusing on distant objects, it will peer back in time, almost to the Big Bang 13.7 billion years ago.  Bird flu: A dead duck?Health officials warned of a major bird flu pandemic ripping across the world as early as 2004. But it still hasn't happened. Was it scaremongering? Statisticians pick over the evidence.  The many worlds of Arthur C. ClarkeHe was many things - an engineer, a thinker, a novelist. But Arthur C. Clarke was most of all a visionary who had an incalculable influence on space travel, space exploration, and astrobiology.  Enzymes made to orderIn a world first, scientists have managed to synthesise entirely new functional enzymes that could pave the way to reactions not seen in the natural world.  Next stop: MarsWhat will it take to plant booted feet on Martian soil? And what will it take to keep them there indefinitely? We set our sights on the Red Planet.  Six things you didn't know about human missions to MarsWhy the first astronauts to Mars may never come back, why a Martian colony is unlikely to revolt against Earth and more...
