Scientists Turn Bacteria Into Living Hard Drives
By feeding strings of human-written data into colonies of bacteria, scientists have discovered a way to turn tiny cells into living, squirming hard drives. A team of Harvard scientists led by geneticist Seth Shipman has just developed a fascinating way to write chunks information into the genetic code of living, growing bacterial cells. It could be the code for a computer program or the lines of a poem. Either way, these living memory sticks can pass this data onto their descendants, and scientists can later read that data by genotyping the bacteria.
