DNA computer performs calculations without continuous power

Researchers at Maynooth University demonstrated a DNA computer that completes calculations without a continuous electricity supply, New Atlas reported. Short DNA segments combine with a larger DNA scaffold in warm saline solution. As the mixture cools, the molecules settle into a structure that represents the answer. The team tested several programs, including calculations up to 100 bits in size. Adding three and 10 took around 30 seconds. A researcher described the system as faster than other DNA computers, but said it is slower than silicon computing and is not intended to match its speed.
