Don't Miss: Vampire Plant Sniffs Out Its Prey They call it strangleweed, devil guts, witches shoelaces... It is the dodder plant, a vampiric weed that seeks out its prey, coils around it and begins to drain its host of its lifeblood. NPR's David Malakoff has a piece on the dodder tonight. What is interesting (besides the whole obviously-created-by-Satan thing) is that scientists have figured out how the plant finds its prey. It smells them. Give it a whiff of tomato and it begins to creep toward the plant. And it likes tomatoes better than, say, wheat. Yet one more sure sign of the apocalypse.
