Live Science reports that scientists built a DNA computer that calculates in a drop of water. A post describing Maynooth University’s Scaffolded DNA Computer says it ran 10 molecular programs, including 100-bit calculations. The account describes a technique called DNA origami: one long DNA strand and hundreds of shorter synthetic “staple” strands self-assemble into a microscopic computing grid after heating and cooling in water and salt.

@MediaQSI🧬 Researchers create DNA computer that performs 100-bit calculations without electricity A team of researchers at Maynooth University, Ireland, has created a “first-of-its-kind” DNA molecular computer that uses DNA strands to perform complex mathematical operations without electricity. Detailed in the journal Nature, the system — called a Scaffolded DNA Computer (SDC) — is one of the most complex and fastest molecular computers, and “points to new possibilities for long-term data storage, energy-efficient computation and, in time, molecular systems that could operate inside cells for applications such as disease detection,” according to the researchers. The researchers designed the computer via a technique known as DNA origami. Using specialized software, they mapped out a long primary DNA strand and hundreds of shorter, custom-synthesized “staple” strands. They then added the physical DNA strands to a test tube containing a drop of water and salt. When they heated and then cooled the mixture, the strands self-assembled into a highly organized, microscopic computing grid, with the long strand acting as a structural scaffold. The system successfully executed 10 different molecular programs, including complex 100-bit calculations. 🚀 @MediaQSI

@ohmegamonsterA reusable DNA computer does math in a drop of salt water. Short DNA strands latch onto a longer DNA backbone; heat and cool, and the molecules settle into the right answer — the lowest-energy state — so it does not need constant fuel or heavy error-correction like most molecular computers. Ten programs shown: multiply by 3, divide by 2, error-check, and add numbers up to 25 bits (a 100-bit computation). 700+ runs; simple sums ~30s; larger can take hours. Same mix reused ~24 times; one rerun 1.5 years later after adding water. Unlock: programmable molecular logic you can run again — computing inside chemistry or biology without silicon, without tossing the molecules after one shot.

@serge_golubevIrish scientists just dropped the most complex DNA computer yet 🧬💻 Maynooth University unveiled the Scaffolded DNA Computer (SDC): a DNA-origami molecular computer. 🧬 One long DNA strand = structural scaffold. Hundreds of short synthetic “staples” click into precise spots, forming a computing lattice. 🧬 The program is encoded directly in the DNA bases (A, T, C, G) before it goes into solution. Heat starts the computation, then the molecules self-assemble into the most thermodynamically stable structure — and that’s your answer. 📏 It ran 10 different programs — add, subtract, multiply, divide — and handled 100-bit calculations with zero errors. It can even run up to 25 computations in a row in the same solution without losing accuracy. 🧪 Key flex vs. traditional computers: (https://tech.yahoo.com/science/articles/researchers-create-dna-computer-performs-123000833.html?guccounter=1) no constant power needed. It runs autonomously on chemical reactions. No battery, no plug — just chemistry doing its thing. 🙌 Event Horizon

@SciNatureNews🚨: Scientists have built a computer that performs calculations using billions of DNA molecules in a drop of water. The Scaffolded DNA Computer uses DNA strands that self assemble into programmable structures. Instead of continuously using electricity to process instructions the system lets molecular interactions settle into an energetically favored state that represents the answer. Researchers tested 10 different programs including multiplication division parity detection and addition of 25-bit numbers. One system handled a 100-bit calculation and small versions completed tasks in under a minute. The computer is far slower than conventional silicon hardware so this is not a replacement for your laptop. Its importance is showing that computation can be built directly into molecular systems with very little ongoing energy input.

@EDUCATEDGUESS6A DNA computer ran ten programs, including a 100-bit task, by settling into its lowest-energy state. It is a lab system, not a silicon replacement. Its promise lies in biological settings, smart materials and archival storage, where chemistry computes. https://www.nature.com/articles/s41586-026-10996-5
