Why I Love Scientists

Two articles in Harvard magazine remind me why I am so optimistic about scientific breakthroughs making the world a better place:
1. Researchers including Wayne Marasco may have found the Achilles heel of the flu virus.
2. When Amy Wagers surgically joined a young mouse and an old mouse so that their bloodstreams became shared, healing to muscle damage in the old mouse occurred much faster than it did in other old mice. Something in the young mouse’s blood helped repair the old mouse’s tissues. If that “something” can be isolated, who knows how many different uses it might have.
My prediction: the first humans to get their hands on that “something” will be professional bike racers.
