Por Que Alguns Humanos Antigos Consumiam Seus Mortos?

For generations, in the isolated mountains of Papua New Guinea, a gesture of love and mourning has silently transformed into one of the strangest diseases ever recorded by medicine. How could a funeral ritual full of emotional significance open the doors to a biological mechanism completely new to science? This video explores the accidental history of kuru, when the act of honoring the dead through the consumption of the brain became, unbeknownst to anyone, the transmission route for an invisible protein called a prion. Over decades, what seemed like a curse revealed itself to be misunderstood biology — a discovery that would forever change our understanding of the human brain. From remote mountain villages to Nobel Prize-winning laboratories, this is the incredible and disturbing story of how the deepest love for the memory of loved ones hid, for generations, a danger that science would take decades to understand.
