Rewritable Holographic Memory
A genetically engineered microbial protein could mean better data storage.
By using lasers to etch data onto microbial proteins, researchers at the University of Connecticut may have demonstrated a way to produce rewritable holographic memory. Holographic memory stores data in three dimensions instead of two and could make data retrieval hundreds of times faster. The first holographic-memory systems have recently come to market, but they do not yet feature discs rewritable in real time.
