Australian expat biologist David Sinclair has been doing the rounds among business people, politicians and scientists in Boston in a bid to raise no less than a billion dollars.

The money is to fund a project that could affect every person in the world. Within his grasp is an anti-ageing cure that he believes could expand the human lifespan by at least 10 years.

"Our goal is to alleviate human suffering in old age," said Professor Sinclair, founding director of the Paul F Glenn Center for the Biological Mechanisms of Aging at Harvard University.

"It's a moon shot but we think we have the technology. It's easy to do in a mouse, now it's about translating that into humans. It's not a question of if but when."
