Summary

About 8000 years ago, people were drawing dogs with leashes, according to a series of newly described stone carvings from Saudi Arabia. Online News Editor David Grimm talks with Sarah Crespi about reporting on this story and what it says about the history of dog domestication. Sarah also interviews physicist Brad Marston of Brown University on surprising findings that bring together planetary science and quantum physics. It turns out that Earth’s rotation and the presence of oceans and atmosphere on its surface mean it can be described as a “topological insulator”—a term usually reserved for quantum phenomena. Insights from the study of these effects at the quantum level may help us understand weather and currents at the planetary level—including insights into climate change and exoplanets.
