Monday 12th February 2024. Biology is undergoing a quiet but profound transformation. Several aspects of the standard picture of how life works have been exposed as incomplete, misleading, or wrong. Philip Ball explores the new biology, revealing life to be a far richer, more ingenious affair than we had guessed. There is no unique place to look for an answer to this question: life is a system of many levels—genes, proteins, cells, tissues, and body modules such as the immune system and the nervous system—each with its own rules and principles. In this talk, discover why some researchers believe that, thanks to incredible scientific advancements, we will be able to regenerate limbs and organs, and perhaps even create new life forms that evolution has never imagined.
