Mark Zuckerberg pledges $3bn to help scientists cure diseases

        Mark Zuckerberg and his wife Priscilla Chan on Wednesday pledged over $3 billion towards helping scientists find a way to cure diseases. The statement released via his official Facebook page:
Priscilla and I just shared our next major focus for the Chan Zuckerberg Initiative. Can we help scientists to cure, prevent or manage all diseases within our children's lifetime? I'm optimistic we can. Medicine has only been a modern science for about a century, and we've made incredible progress so far.

       Life expectancy has increased by 1/4 of a year per year since then, and if we only continue this trend, the average will reach 100 around the end of this century.
Today, just four kinds of diseases cause the majority of deaths. We can make progress on all of them with the right technology.
       Throughout history, most scientific breakthroughs have been preceded by the invention of new tools to help us see problems in new ways -- like the telescope, the microscope and DNA sequencing. It's not hard to imagine the modern tools required to accelerate breakthroughs in today's four major disease areas.
