What are those colors you see when you rub your eyes? | Paul CJ Taylor
In the 1600s, Isaac Newton conducted a series of experiments to better understand the lights and colors that sometimes appear when your eyes are closed. If you’ve ever sat around an evening campfire or unintentionally glanced at the Sun, you may have noticed illuminated patterns briefly dance along your vision. So how do these visual illusions form? Paul Taylor explores the science of afterimages. [Directed by Sofia Pashaei, narrated by Alexandra Panzer, music by Cem Misirlioglu, WORKPLAYWORK]. Hosted on Acast.

Interview: How do kidney transplants work? | Alexander H. Toledo
In 1954, Joseph Murray attempted a type of kidney swap that no doctor had tried before. The surgery was a success, and the patient would go on to live with the transplanted organ thanks to one key factor: it came from his identical twin. 70 years later, nearly 100,000 kidneys are transplanted annually in the US alone. So how does this surgery work today? Alexander H. Toledo explains the procedure. [Directed by Biljana Labović, narrated by Addison Anderson].Extended content: After the talk, Shoshana speaks with Leilani Graham, a writer and healthcare consultant, who survived four cardiac arrests and then a heart transplant about her personal trials and the realm of organ transplants.
