Yeast prions: DNA-free genetics?
Article Abstract:
Geneticist Susan Lindquist and her colleagues have found evidence suggesting that a protein can pass on a trait simply by being present in a cell. The research is supportive of the existence of prions, infectious particles believed to cause some neurological diseases in humans.

Flipping yeast
Article Abstract:
Researchers, who are trying to prove whether prions from one mammal can infect another one and 'flip' its proteins, are using yeast as a scientific model. One group of scientists has found that a protein called hsp 104 helps flip PSI yeast.

Putting prions to the test
Article Abstract:
Some researchers believe in the existence of prions, or proteinaceous infectious particles. These infectious proteins may be responsible for diseases such as mad cow disease, scrapie and Creutzfeldt-Jakob disease.
