Artificial Prion Created

jabberjaw writes "Nature is reporting that researchers at the University of California San Diego have created a synthetic prion which, when injected into mice will bring about symptoms similar to those displayed by cattle suffering from bovine spongiform encephalopathy, aka mad cow disease. The researchers first crafted healthy prion proteins using bacteria. They then shook these proteins until they resembled the tangled structure of an unhealthy prion. Afterwords, these prions were injected into the brains of mice who fell ill two years later. Perhaps someone who is more familiar with this field of research would care to fill us in on the details as the article was rather light."
