Science podcast: alien invaders

This week: Two new studies outline characteristics that help alien species become invasive. India rethinks its ambitious nuclear energy plans. A new study shows what we might have known all along – human language originated in Africa. Yet another study suggests that rules of grammar are far from universal. Also, our ongoing Science Forum discussion about how our physical environments influence human behavior goes until Thursday, April 21st. So, stop by and add your thoughts and questions to the conversation here. (Photo: The Burmese python has invaded parts of the U.S. Credit: U.S. National Park Service.)
