BlueCup writes "The question of how a dodder finds a host plant has puzzled researchers. Many thought it simply grew in a random direction, with discovery of a plant to attack being a chance encounter. But the researchers led by Consuelo M. De Moraes found that if they placed tomato plants near a germinating dodder, the parasite headed for the tomato 80 percent of the time. And when they put scent chemicals from a tomato on rubber, 73 percent of the dodder seedlings headed that way. Turns out, it sniffs out it's prey."

Google has set up a subsidiary, Google.org, a for-profit philanthropy with initial capital of a billion dollars. Not being organized on a tax-free basis carries both advantages and drawbacks. From the article: "Unlike most charities, this one will be for-profit, allowing it to fund start-up companies, form partnerships with venture capitalists and even lobby Congress. It will also pay taxes." One of Google.org's first projects is the development of a plug-in hybrid vehicle that achieves a mileage rating equivalent to 100 MPG.
