Those studies showed that when the scientists engineered hormone-sensitive cells to overexpress genes for the androgen receptor, the cells behaved like hormone-refractory ...Do we perceive using 'mindsight'?

Another key find in the FSU study is that prions formed in host cells are amyloids, a family of fiber-forming proteins that often are associated with neurological disorders in humans.
