This is all of 24 hours old, so I know it's already ancient history in the blogosphere, but I did want to mention the news of Warren Buffet's ~$37 billion donation to the Bill and Melinda Gates Foundation. (As Stephen Colbert put it, Buffet's so rich that he's hired Bill Gates to spend his money.)
This means additional funding for research into and prevention of diseases such as TB, malaria, and guinea worm, in addition to increased education funding here in the US. And, this donation is in addition to the amount he already invests in his own foundation, the Susan Thompson Buffett Foundation (recently renamed in memory of his wife), which promotes women's health. 'tis a good day for global health, indeed.
