Recommendation

How do you feel about disembodied, possibly conscious mini-brains grown from human stem cells? Would they represent a thrilling scientific advance that could be used for the good of humanity, or a sin against God and nature? Should they be used in scientific experimentation, and if so, should there be strict policies guiding their use? If you’re not sure where you land on that issue, you’re not alone. In this article from Nature, journalist Sara Reardon explores the many moral quandaries plaguing neuroethicists who are tackling this issue. 

Take-Aways

  • Scientists are growing human brain “organoids” in labs.
  • Experts are unable to agree on a definition of consciousness.
  • Ethicists and scientists are attempting to create guidelines for the humane use of organoids.
