Some people have the green thumb in their family. Others may complain that they fail with plants because plants don’t tell them when they need care. Of course, most people can do well with family pets, who are enthusiastic about letting their needs be known.

 Now scientists have learned that plants do indeed cry out when they need attention. We just haven’t heard them because the sounds made by a thirsty plant are about five times higher-pitched than we can hear. But scientists with tiny, specialized microphones have heard corn plants calling for water.
