The biocomputer in action, with proteins finding their way to the solution set at the bottom.

Oh and about that energy efficiency? Lund's Heiner Linke says that they require less than one percent of the power a traditional transistor does to do one calculation step.

The CBC reports that the model biocomputer used in the experiment is only about the size of a book, rather than, say, IBM's Watson (pictured above) that's comprised of some 90 server modules. The ATP-powered biocomputer is admittedly limited for now (it's only solved {2, 5, 9}), but the scientists involved say that scalability is possible and we might not be far off from seeing the tech perform more complex tasks.

"Our approach has the potential to be general and to be developed further to enable the efficient encoding and solving of a wide range of large-scale problems," the research paper says.
