Electrons move so quickly that, until recently, their motion was impossible to observe. In this episode, James Gaynor, an assistant professor of chemistry at Northwestern University and member of the International Institute for Nanotechnology, takes listeners inside the race to watch electrons move in real time. Using ultrafast laser tools that capture events lasting mere attoseconds, Gaynor's lab is uncovering the earliest moments of how light interacts with matter. He explains how this fundamental research could one day help scientists design faster electronics, more efficient energy technologies, and advanced bioelectronic devices by understanding chemistry at its beginning.

In honor of Star Wars Day, this episode explores futuristic light technologies seen in science fiction—like invisibility cloaks or powerful directed energy— and how far away we are from such innovations. In this episode, Matt Jones, a chemist at Rice University and Northwestern alum, explains how scientists are learning to control light by engineering materials at the nanoscale and why when materials are reduced to billionths of a meter, they begin to exhibit entirely new optical properties—from color-changing nanoparticles to structures that interact with light in unexpected ways. The conversation explores the emerging field of metamaterials and how curiosity-driven, fundamental science lays the groundwork for innovations that may shape the future.

The future of robotics isn't just smarter software, but smarter materials. In this episode, Northwestern University's Ryan Truby explains how his lab is designing soft, bio-inspired robots powered by artificial muscles and nanoscale engineering. From safer human-robot interaction to real-world applications like disaster response and health care, he shares how rethinking a robot's body could transform what machines can do.
