Prions jump species barrier
Test tube experiments may help identify the most hazardous prion proteins.

Infectious prion proteins from hamsters can change normal proteins from mice into new, infectious forms of prion - simply by mixing the proteins together in a test tube.
Researchers at the University of Texas Medical Branch in Galveston suggest their discovery could be turned into a useful test for whether a given prion strain is transmissible from one species to another.
