Plants Recognize Their Siblings, Biologists Discover
"The ability to recognize and favour kin is common in animals, but this is the first time it has been shown in plants" said Susan Dudley, associate professor of biology at McMaster University in Hamilton, Canada. "When plants share their pots, they get competitive and start growing more roots, which allows them to grab water and mineral nutrients before their neighbours get them. It appears, though, that they only do this when sharing a pot with unrelated plants; when they share a pot with family they don't increase their root growth.

Reid: 'It's time to change course' in Iraq
"We're now in the fifth year of ground combat operations in Iraq and this deck of cards is coming crashing down," he said.
THINK !
Who Will Be Blamed For the Aftermath if US Retreats From Iraq?
So where's the little Baghdad going to be? Or the little Karbala or the little Fallujah? And do we think Americans are just going to stand by and watch a genocide play out?
The Whole World Watched ... and is still watching ...
