Shining A Light On Dark Energy, More Than Trees, Senior Portrait: Julia, and The Deakins Line

The universe is expanding and we have a better idea of how quickly thanks to the efforts of Johns Hopkins Astrophysicist Adam Riess. We talk with the Nobel-prize winning physicist about his work. Then, at one level, trees provide the fibers that bind the essays together in Angela Pelster's new book, Limber. But her conversation with Nathan shows the book is about much more than branches and leaves. And, we continue our senior portraits series with a visit with a woman who recalls growing up in Baltimore’s Remington neighborhood 70 years ago. Plus, border disputes have popped up between Maryland and neighboring states for as long as their borders existed. Today, we look back at a Supreme Court decision that decided Maryland's far western border.
