Dr. Kiki Sanford is a neurophysiologist, a popular science communicator and creator of This Week in Science (TWIS) podcast and radio show. This is her fourth appearance here. In this episode, we chat about some some very interesting recent topics on TWIS. 1) Researchers showed that mini human brains implanted into mouse brains survived and functionally integrated into the host tissue. 2) Magnetoreception in birds is possible thanks to a protein in their eyes. They may actually have a heads-up display in their eyes for the Earth’s magnetic field. 3) Amazon’s announcement of its Vesta family robot project. 4) A new, non-invasive patch is being developed to allow diabetics to monitor their gluscose levels. Kiki has a special way of inspiring us to learn about science, so don’t miss BGM’s most popular guest.
