Facebook founder Mark Zuckerberg and wife Priscilla Chan have declared their aim to cure, prevent and manage all disease by the end of the century.
Chan and Zuckerberg will stump up at least $3bn (£2.3bn) for the effort over the next 10 years. That is not a vast sum for the task ahead. The new Francis Crick Institute in London, now filling with 1,400 scientists, could be built and run for 10 years on that. The Wellcome Trust itself will spend £5bn on biomedical research in the next five years alone. But part of Chan and Zuckerberg’s hope is to grow a movement to fund science: where they have led, they want other wealthy individuals to follow.
