💧 A Computer Inside a Drop of Water

At Maynooth University in Ireland, a saltwater drop containing DNA answered 10 + 3 = 13 in 30 seconds. There are no chips or wires. Short DNA strands and one long scaffold strand are briefly heated, then self-assemble as the drop cools. The system needs no continuous power.

The resulting molecular pattern is the answer. The molecular processor ran 10 programs and reused the same drop up to 25 times without losing quality.

Large numbers expose the limit. Adding numbers up to 34 million took about 14 hours. It will not replace a smartphone, but its developers call it the fastest DNA computer.
