World-first unpowered DNA computer sets speed record

Researchers at Maynooth University in Ireland built a DNA computer that performs calculations without a constant electricity supply by relying on DNA origami self-assembly. The system handles problems up to 100 bits, with its fastest calculation (3+10) taking about 30 seconds — faster than other DNA computers.

• DNA computer runs without continuous power via molecular self-assembly
• Handles problems up to 100 bits; adding 3+10 took about 30 seconds
• Fastest among DNA computers, though slower than silicon
• One gram of DNA could theoretically store hundreds of millions of gigabytes
