Animal testing is cruel, unethical, and dangerous to humans. The National Institute of Health has admitted that 95% of animal tests - which cost US taxpayers more than $15B per year - fail to translate to humans. This money would be better spent on new methods, including the use of microchips that construct postage stamp-size organs from human cells.
This revolutionary treatment is a major breakthrough that could one day save the lives of people who would currently be considered dead. Although there's a long way to go before human application, the practical use of this system could eventually keep organs healthy for longer and provide those in need with transplants.
There is a 27% chance that any human will live without the assistance of medical life support for at least 100 days after the receipt of a lab-grown organ before 2025, according to the Metaculus prediction community.
