We are here to celebrate the completion of the first survey of the entire human genome. Without a doubt, this is the most important, most wondrous map ever produced by human kind.

I think actually that the speech work I do is fine. It's important, because I try to help people think about what's going on and organize their lives accordingly.

The more children see of violence, the more numb they are to the deadly consequences of violence. Now, video games like 'Mortal Kombat,' 'Killer Instinct,' and 'Doom,' the very game played obsessively by the two young men who ended so many lives in Littleton, make our children more active participants in simulated violence.

Through scientific discovery and technological innovation, we enlist the forces of the natural world to solve many of the uniquely human problems we face - feeding and providing energy to agrowing population, improving human health, taking responsibility for protecting the environment and the global ecosystem, and ensuring our own Nation's security. Scientific discoveries inspire and enrich us, teaching us about the mysteries of life and the nature of the world.

For too long we've been told about 'us' and 'them.' Each and every election we see a new slate of arguments and ads telling us that 'they' are the problem, not 'us.' But there can be no 'them' in America. There's only us.

We know there are billions of stars and planets literally out there, and the universe is getting bigger. We know from our fancy telescopes that just in the last two years more than 20 planets have been identified outside our solar system that seem to be far enough away from their suns - - and dense enough - - that they might be able to support some form of life. So it makes it increasing less likely that we're alone. But if we were visited someday, I wouldn't be surprised.
