Wikipedia: The navel orange.
"A single mutation in 1820 in an orchard of sweet oranges planted at a monastery in Brazil yielded the navel orange.... Today, navel oranges continue to be produced via cutting and grafting. This does not allow for the usual selective breeding methodologies, and so not only do the navel oranges of today have exactly the same genetic makeup as the original tree's, they can even be considered to all be the fruit of that single, now centuries-old tree."

New York Times: Dark energy -- a universe for beginners no more.
"But even if somebody were to figure out whether or not dark energy changes across time and space, astronomers still wouldn't know what dark energy itself is. ‘The term doesn't mean anything,’ said David Schlegel of Lawrence Berkeley National Laboratory this past fall. ‘It might not be dark. It might not be energy. The whole name is a placeholder. It's a placeholder for the description that there's something funny that was discovered eight years ago now that we don't understand.’"

L.A. Times: Ethanol still a long way off in U.S.
"Although Bush and others regularly point to Brazil as an example of what a determined nation can do to reduce its dependence on oil -- most motor vehicles in Brazil run on a blend of 80% ethanol and 20% gasoline -- there are huge differences. Brazil has been subsidizing its ethanol industry for several decades, and has a huge crop -- sugar cane -- that can efficiently be refined into ethanol." ...
"To achieve Brazil's results, the U.S. would have to turn all of its crop-producing acreage over to corn and use all of the corn for ethanol...."
