There should be reference material for researchers on which science fiction sounds like a good idea. Scientists are exploring the creation of "bodyoids," which are human bodies grown in artificial wombs without consciousness or the ability to feel pain. These bodyoids could provide a new source of organs for transplants, reducing the long waiting lists for patients.
They might also help in testing new medicines, potentially decreasing the need for animal testing and making drug development more efficient. While this idea raises ethical questions, believers in the idea think bodyoids could revolutionize medicine by offering ethical alternatives to current practices involving sentient beings. They suggest starting with small-scale tests on animals to explore the feasibility of this approach.
