Studying Biology: • Start with a question. –For example: How? Why? When? Where? Etc? • How do we get answers? –Strong Inference presents one method (article on webpage)
What causes Mad Cow Disease (aka BSE)?
Brain tissue from cow with BSE. Scrapie in sheep, CJD or Kuru in humans looks similar.
How could you test for the infectious agent?
