As medical research continues and technology enables new breakthroughs, there will be a day when malaria and most all major deadly diseases are eradicated on Earth.

The thing is I think vaccines are one of the greatest medical breakthroughs that we have. I'm a big fan and a great fan of the history of the development of the smallpox vaccine, for example.

If someone is always to blame, if every time something goes wrong someone has to be punished, people quickly stop taking risks. Without risks, there can't be breakthroughs.

The Internet has made some phenomenal breakthroughs that are still only poorly understood in terms of changing people's ideas of us and them. If mass media, social isolation in the suburbs, alienating workplaces and long car commutes create a bunker mentality, the Internet does the opposite.

Technological breakthroughs in energy storage will make renewable power cheap enough to use in more places and accelerate the move to electric cars and other electric transportation systems.

There are no rules. That is how art is born, how breakthroughs happen. Go against the rules or ignore the rules. That is what invention is about.

Continue going after your dreams because you deserve them; life has many incredible experiences ahead of you. Today's obstacles are tomorrow's victories, and tomorrow's breakthroughs are today's possibilities.

And I'm going to work as hard as I can... for cancer research and hopefully maybe we'll have some cures and some breakthroughs. I'd like to think I'm going to fight my brains out to be back here again next year for the Arthur Ashe recipient. I want to give it next year!

We have a lot to gain through furthering stem cell research but medical breakthroughs should be fundamentally about saving not destroying human life. Therefore I support stem cell research that does not destroy the embryo.

Historic changes and challenges. Breakthroughs in human knowledge and opportunity. And yet for vast numbers across the globe the daily realities have not altered.
