A lot of people owe Prince Charles an apology: Plants do talk to each other, according to a new British study. We're not sure what exhortations His Royal Highness has been whispering all these years, but we're going to start offering encouragement to our plants, too:

"I promise not to eat you."

"That house plant over there just called you puny."

Bristol University researchers used loudspeakers to eavesdrop on plants and heard them make clicking sounds with their roots to communicate. If separated from one another, plants will grow in the direction of the clicks, according to the Daily Mail.
