Mini-brains may already be sentient and suffering, scientists warn

To prevent torturous experiments on organoids, some are calling for clearer definitions of consciousness.

Surprising Science
  • Mini-brains (also called organoids) are tiny lumps of tissue capable of generating rudimentary neural activity.
  • Neuroscientists use mini-brains to conduct research and experiments that help them learn about the brain.
  • As scientists generate increasingly complex mini-brains, however, some are concerned they might be experiencing pain.

Men with psychopathic traits are more desirable to women, Canadian researchers say

The results have startling implications about the evolution of psychopathy in humans.

  • The researchers asked about 50 male university students to participate in a mock dating scenario.
  • Men with more psychopathic traits were seen as significantly more desirable by women who watched videos of the encounters.
  • Psychopathic traits may help men to mimic the qualities women are looking for, but it's a short-term strategy that comes at a cost.

Conscious machines: How will we test artificial intelligence for feeling?

A review of the multifaceted questions we'll ask to determine whether robots have a felt quality of experience — an "inner feel."

  • The reason we entertain thought experiments such as reincarnation and an afterlife is because we're sentient beings. These concepts are innate to our experiences as conscious human beings.
  • The ACT test probes A.I. to examines whether it can grasp these questions — i.e., the mind existing separately from the body, or the system without the computer. If so, then there's reason to believe it's a conscious being.
  • For machines to develop consciousness, they will need to have the right architectural features. For instance, for humans we possess a working memory, attention, and brain stems — all of which serve as the neural basis of our conscious experience. If there is a machine analog to these things, then it may suggest that the machines are conscious as well.
