With its pleasant climate, Florida has become home to more exotic and invasive species of plants and animals than any other state in the continental U.S. Some invasive species have been brought in deliberately, such as the Burmese python or the Cuban brown snail. But the majority of species are imported inadvertently as cargo.
Amanda Hodges, who heads the biosecurity research lab at the University of Florida, says that until recently, scientists saw about a dozen new bugs arrive in Florida each year.
Harry Kaplan practices pitching during Home Run Baseball Camp at Friendship Recreation Center in June. Kaplan's arm is stretched long and toward the ground as his hips are faced away from the catcher. A chimp, in contrast, could never throw a fastball.
The ability to throw a baseball or any object with speed and precision is unique to us humans. And that ability depends on certain features of our anatomy that arose in our ancestors over 2 million years ago, according to a study published in this week's issue of the journal Nature.

New observations of a fairly well-studied star have revealed a system with at least six planets, three of which are in the star's habitable zone. This is the first time that three such planets have been spotted orbiting in this zone in the same system.
