DNA used as rewritable data storage in cells

Genetically encoded memory could track cell division inside the body

They aren’t yet competition for Intel, but bioengineers have created a one-bit “memory” made of DNA that can record, erase and rewrite data within living cells.

One day, doctors might be able to insert such devices into a cancer patient to tally how many times a cell divides and flag when to shut the cancer down. Or researchers might track exactly what happens inside cells as they age.

The work is a step forward in synthetic biology, a new field in which scientists create tools to control life’...
