【生物电脑:以蛋白质供能】

【生物电脑:以蛋白质供能】一个多校联合研究团队近日公布了其开发的生物电脑(biocomputer)隆德大学研究者Heiner Linke称生物电脑在进行运算时所需能量仅为传统晶体管电脑的1%,同时以蛋白质而非传统电能为能量来源。同时,还放出了一张动图表现蛋白质在电脑运算过程中的走向。

Scientists built a book-sized, protein-powered biocomputer

Supercomputers are absurdly impressive in terms of raw power, but it comes at a price: size and energy consumption. A multi-university team of researchers might've sidestepped that, though, with protein-powered biocomputers. Lund University notes that where this should really be helpful is with cryptography and "mathematical optimization" because with each task it's necessary to test multiple solution sets. Unlike a traditional computer, biocomputers don't work in sequence, they operate in parallel -- leading to much faster problem solving.
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.
