"Mad Cow" Mechanism May Be Integral to Storing Memory, Whitehead Inst Press

Excerpts: 
 
 
(...) yeast cell turns blue.  
 

Scientists have discovered a new process for how memories might be stored, a
finding that could help explain one of the least-understood activities of the
brain. What's more, the key player in this process is a protein that acts just
like a prion - a class of proteins that includes the deadly agents involved in
neurodegenerative conditions such as mad cow disease. 

The study, (...), suggests that this protein does its good work while in a prion
state, contradicting a widely held belief that a protein that has prion activity
is toxic or at least doesn't function properly.
