Ologies with Alie Ward - Paleohistology (WHY TEETH EXIST) with Yara Haridy

Excuse me, why do you have teeth? How did they get in your mouth and where did they come from? Let’s ask researcher, tooth enthusiast, and Paleohistologist Dr. Yara Haridy.  She opened up the archives at Chicago’s Field Museum to chat about ancient skulls, drawers of bones, and the evidence that changed how we think about chompers. Drop your jaws as we discuss the origins of teeth, why yours hurt, the long-debated rumors of extinct species, how particle accelerators and paleontology worlds collide, what tools fossil pickers rely on, teeny tiny mysteries, why you should hug a tree before it kills you, and why a catfish might become your overlord.

Is there anything you wouldn’t do for your favorite person? That question is at the center of Sarah Harman’s debut novel All the Other Mothers Hate Me. The book follows a single mom, Florence, who goes to extreme lengths to defend her son when he becomes a suspect in the disappearance of his school bully. In today’s episode, Harman tells NPR’s Ayesha Rascoe about her misfit protagonist and her observations of British culture from an outsider’s perspective.

Short Wave - A failed galaxy could solve the dark matter mystery

Cloud 9 is a failed galaxy. It’s a clump of dark matter, called a dark matter halo, that never formed stars. But this failure could be the key to a mystery almost as old as the universe itself: dark matter. Scientists don’t know what dark matter is, but Cloud 9 could offer new clues. Three researchers weigh in on this new discovery and why it could be a missing piece to the story on how the universe formed.
