Learn about a revolutionary approach to DNA computing that overcomes the single-use limitation of traditional molecular computing systems through this 25-minute conference presentation. Discover how the Scaffolded DNA Computer (SDC) leverages thermodynamic principles to execute computations using simple thermal annealing, naturally reaching correct outputs by moving to equilibrium without requiring explicit error correction mechanisms. Explore the system's demonstrated capabilities in performing arithmetic and cellular automata computations on 12-bit and 24-bit memory in under a minute, and scaling up to 75 bits over several hours. Understand the breakthrough concept of renewable DNA computing, where the same molecular mix can be reset and reused multiple times using just two DNA strands - one for program reset and another for new input introduction. Examine how these thermodynamically favoured principles extend to DNA storage platforms, enabling computable, scalable, rewritable, and sustainable alternatives to destructive sequencing methods. Gain insights into how this approach reduces material waste, minimizes energy consumption, and creates pathways for long-term, low-energy computing and storage technologies that could transform molecular computation from disposable to renewable systems.
