Global data production is estimated to reach 463 exabytes per day by 2025 — which is the equivalent of 212,765,957 DVDs per day, per the World Economic Forum.
Our existing data-storage systems, which can hold only so many 0s and 1s, and consume huge amounts of energy and space, cannot last us forever, putting us on the cusp of a serious data-storage problem that can only worsen over time. DNA-based data storage may come to the rescue as an alternative to hard drives since our genetic code is millions of times more efficient at storing information than current solutions. Now, in a breakthrough development, researchers at Northwestern University have devised a new method for recording information to DNA that takes minutes rather than hours or days.
The researchers utilized a novel enzymatic system to synthesize DNA that records rapidly changing environmental signals straight into its sequences, and this method could revolutionize how scientists examine and record neurons inside the brain.
