Leading Edge brings you the latest news from the world of science. Geoff Watts celebrates discoveries as soon as they're being talked about - on the internet, in coffee rooms and bars; often before they're published in journals. And he gets to grips with not just the science, but with the controversies and conversation that surround it.

"If what interests you are new and exciting ideas, it's science you should be turning to. And whether it's the Human Genome Project or the origins of the Universe, Leading Edge is the place to hear about them."

This week on Leading Edge - the Chelsea Flower Show, planetary billiards, SALT and walking octopuses.
Planetary Billiards
An international team of scientists have come up with a single theory that explains three great mysteries about our Solar System: how the moon got its craters, how Jupiter got its Trojans and why the giant planets have tilted orbits.
Geoff Watts talks to Dr Alessandro Morbidelli from the Observatoire de la C么te D'Azur, in Nice, France about these findings, published in the journal Nature this week.
Chelsea Flower Show
Geoff Watts visits the Chelsea Flower Show to see how plants are 'grown' in microchips.
Scientists from John Innes Centre are using their knowledge of the simple rules that control plant听development to model plant growth in computers.
Geoff also finds out how horticulture and science can combine to bring about environmental improvement.听A new rooftop water recycling system (GROW) uses plants to filter dirty water in homes so that it can be re-used.
Walking Octopuses
Molly Bentley visits the University of California Berkeley to learn that up-right walking is not restricted to creatures with a hard skeleton.
The discovery of walking octopuses suggests a new scenario for the evolution of walking and provides a model for a new generation of soft robots.
South African Large Telescope
SALT - the Southern African Large Telescope is a flagship project intended to demonstrate that the frontiers of science are not entirely reserved for the developed world.
When up and running, this incredible structure will allow scientists to view distant stars and galaxies a billion times too faint to be seen with the unaided eye, and will answer important questions about the nature of the Universe.
