Tropics Expand and Stem Cells Repair Major Skull Damage

  • It's official: the Earth is getting more tropical. Global warming has expanded the tropical band around the center of the planet over the past two decades, and it looks like it will expand more over the next century. [Reuters]
  • Researchers repaired major skull damage in mice using human embryonic stem cells. They grew new bone on a special tissue-engineering edifice and popped it right into the mouse skulls. So stem cells are good for something, after all. [Science Daily] Why chimps are smarter than humans and dinosaurs had hooves after the jump.
