"There's never a time that I'm not actually looking fort these species because, we say they're extinct, but I believe they are there," he said. "It's so satisfying, bringing a plant back from the brink of extinction.""

    Researchers have devised a penny-sized silicon chip that uses photons to run Shor's algorithm - a well-known quantum approach - to solve a maths problem. The algorithm computes the two numbers that multiply together to form a given figure, and has until now required laboratory-sized optical computers. This kind of factoring is the basis for a wide variety of encryption schemes.

    It was the year we learned of a spectacular smash-up in space, and scientists working on the world's biggest physics experiment delighted at collisions of an entirely different sort. There were shockwaves, too, in Copenhagen, as the summit failed to reach a consensus on tackling climate change, instead merely noting a deal struck by major powers including the US and China. The BBC's science reporter Paul Rincon looks back at the twists and turns of a year in science and the environment.
