A Mouse With Two Dads — and a New Frontier for Biology | Katsuhiko Hayashi | TED

You’re familiar with the story: a sperm and an egg meet to create an embryo, which has the potential to give rise to new life. But what if you could create a sperm or egg from any cell, even a single skin cell? Biologist Katsuhiko Hayashi discusses the science of in vitro gametogenesis (IVG) —…

You’re familiar with the story: a sperm and an egg meet to create an embryo, which has the potential to give rise to new life. But what if you could create a sperm or egg from any cell, even a single skin cell? Biologist Katsuhiko Hayashi discusses the science of in vitro gametogenesis (IVG) — an experimental technique for creating lab-made sperm or eggs out of just about any type of cell — and explores its implications for endangered species, human reproduction and more. (Recorded at TED2024 on April 18, 2024)

    tl;dr they put a sperm cell nucleus in an egg and fertilized it with another sperm

Lev Zasetsky could have been an anonymous human data point in history’s largest conflict — just another one of tens of millions of casualties in World War II, the treatment of which stretched deep into the Cold War. But his particular brain injury was so peculiar that he drew the interest of Alexander Luria, the Soviet Union’s most accomplished neuropsychologist, as Lev became a complex mix of scientific oddity and miracle.

Zasetsky’s form of aphasia resulted in him being able to write, but not read his own writing or even understand all of what he had written. It’s a case that delves into the earliest history of Popular Science and reframes our modern understanding of psychology, history, language, communication, and the human spirit.
